Maserati Gran Cabrio MC, 2013

 
 
 
  •  Maserati Gran Cabrio MC, 2013
The new Maserati Gran Cabrio MC completes the open-top range with a highly sporty and aggressive look, while maintaining the strengths and characteristics of a true grand tourer, ideal for long journeys.
The Gran Turismo MC Stradale inspired and encouraged by the considerable success, which was warmly received by customers thanks to a masterly translation and adaptation of racing characteristics for use on the road.

Exterior
The new, sporty look can be seen in each stylistic element of the Maserati Gran Cabrio MC's bodywork. Inspired directly by the cars of the Maserati Trofeo MC World Series and the GT4 version, the new design perfectly blends sportiness, dynamism, the search for aerodynamic perfection, elegance and style. These stylistic elements already partly characterised the Gran Turismo MC Stradale and the Gran Turismo Sport, and seamlessly unite form and function.

The car, 48 millimetres longer than the Gran Cabrio and Gran Cabrio Sport, is characterised by a front end which is inspired directly by the MC Stradale, adopting a profile designed to optimise the aerodynamic lift and flow. These differ from those on other versions of the Gran Cabrio due to the increased car length and other aerodynamic elements at the rear end.

The bonnet incorporates two generous air outlets at the centre to optimise cooling of the powerful V8, and two more air outlets to cool down the brake discs have also been added to the two front wings.

Initially introduced on the Gran Turismo Sport the new headlights, which adopt LEDs for the daytime running light (DRL) function, complete the new look of the Maserati Gran Cabrio MC. Though they maintain the external shape seen on the other three versions in the Gran Cabrio range, the new headlights adopt the most modern technology, perfectly enhanced with an extremely sporty look thanks to the matt black colour of the structure.

The bi-xenon unit inside the headlight also incorporates Adaptive Light Control, which follows the movement of the steering by up to 15 degrees.

The rear is characterised by the large spoiler, for greater negative lift at high speeds. Inside the spoiler, built into the luggage compartment, is the third brake light. The standard version comes in the same colour as the body and it is also available, within the various car customisation packages, with a carbon finish.

The bumper has been completely redesigned at the bottom to make the new model even sportier and at the same time ensure optimal aerodynamic efficiency. The circular exhausts have been moved to the centre of the bumper and the specific layout of the air ducts, built into the lower part of the bumper, ensure greater streamlining, stabilising the air flow from the underbody.

Finally, the dynamism of the Maserati Gran Cabrio MC is accentuated by the 20" MC Design rims, available in glossy Titanio or matt Grafite, and made using flow-forming technology. In addition to being lighter, they feature the traditional Trident, skilfully worked into the double-spokes.

Interior
The interior of the Maserati Gran Cabrio MC has received a thorough overhaul with particular attention paid to ergonomics.

The new seats, completely redesigned from both an aesthetic and functional point of view and enhanced with high-quality materials, now ensure the optimum balance of comfort and performance, elegance and functionality. The new structure of both the front and rear seats now incorporates the headrest and is enhanced by an upper, central trim, with a design inspired by the car's front grille.

Particularly important, especially with convertible cars, is the attention paid to the rear passengers. For this reason, the frame for the front seats, which is also available in a completely carbon-fibre version, has been completely redesigned to ensure 20 mm more legroom for the rear passengers.

Particular attention has been paid to the ergonomic and comfort-related aspects of driving. The seats, with an increased profile to enhance their wrap-around structure and lateral containment, ensure sporty driving while guaranteeing superior comfort, even on very long journeys.

The steering wheel features a new design, with the rim flattened at the top and bottom for greater manoeuvrability, also for sports and high-speed use, without interfering with the driver's legs.

The rear seats have been redesigned according to the same logic: maximum comfort, maximum passenger restraint in sports driving and ample use of quality materials.

To complete the new, super-sporty look of the new Maserati Gran Cabrio MC, it incorporates the Trofeo-design steering wheel paddles as standard, with increased dimensions as seen on the Gran Turismo Sport, and an aluminium pedal unit.

The Engine and performance
As with the most sporty Gran Turismo in the range (the Gran Turismo Sport), the Gran Cabrio MC also adopts the new 4.7-litre V8 engine, which delivers 338 kW (460 HP) together with substantial torque of 520 Nm at 4,750 rpm.

The pistons, positioned at an angle of 90°, are made of reinforced, hardened aluminium, as is the engine block. The crankshaft, with five-point balancing, is made of high-strength steel.

The timing system, with a system of two chains per bank, features dual variable valve timing.

The new power unit, in combination with the MC Auto Shift transmission, is now able to propel the Maserati GranCabrio MC, in closed soft top configuration, to a top speed of 289 km/h (179 mph) with acceleration of 0 to 100 km/h in 4.9 seconds.

Automatic transmission (MC Auto Shift)
Like other sports models in the Maserati range, the Maserati Gran Cabrio MC also adopts an automatic six-speed ZF transmission able to transfer all the power of the 460 HP V8 engine to the ground. Calibrated specifically for application on the sportiest version in the Gran Cabrio range, the MC Auto Shift transmission features five operating modes. It can be used in Auto-Normal, Auto-Sport, Manual-Normal, Manual-Sport and Ice modes.

In Manual mode, gear changes are carried out directly by the driver through the steering wheel paddles, as with a truly manual gearbox. In Manual-Normal mode, the driver can change gear until the threshold value is reached, while in Manual-Sport mode the gear is maintained until the driver next changes gear, even if this may result in over-revving and the intervention of the limiter.

On the Gran Cabrio Sport, Sport mode includes super-fast mode, which derives directly from the Gran Turismo Sport and the Quattroporte Sport GT S and permits gear changes that are 50% faster.

This mode includes automatic blipping (short burst of acceleration) when downshifting with the Launch Control system, called MC Start Strategy(which operates only with MSP deactivated).

Using the MC Start Strategy, the driver holds down the brake pedal, presses the accelerator pedal and then releases the brake pedal when the optimum engine speed is reached (2,300-2,500 rpm).

Chassis and suspension
Performance, safety and comfort were the guidelines that Maserati engineers followed when designing the chassis for the new Gran Cabrio MC. In light of the experience gained with the Gran Turismo MC Stradale, it is fitted with single-rate dampers, to give maximum emphasis to the car's sporty character, which guarantee greater rigidity in order to ensure optimum road holding in all driving conditions, without detracting from maximum passenger comfort.

Braking, always powerful and safe, is guaranteed by Maserati's patented Dual Cast system, which includes brake discs with aluminium bell and steel braking surface, 360×32 mm at the front and 330×28 mm at the back.

This system guarantees the best pedal feeling and braking efficiency, which translates to an excellent stopping distance of 100 to 0 km/h over just 35 metres.

In addition to the conventional holes to optimise cooling of the discs, they also feature grooves which allow the film of water, which deposits on the discs when driving on wet surfaces, to be eliminated and ensure that the operation of the pad's friction material is restored in order to ensure maximum power and braking efficiency at all times.

The one-piece aluminium alloy brake callipers, produced by Brembo and available in various colours, are also six-piston at the front and four-piston at the rear. This configuration ensures greater uniformity in braking, a constant clamping force and the sensation of a stable and reliable pedal, reducing brake wear at the same time.

In deference to Maserati tradition, the monocoque chassis is made with different materials to ensure maximum weight reduction and maximum torsional rigidity. The use of high-strength steels for the structural part and the use of aluminium and composite materials for the moving parts, ensure maximum performance in complete conformity with the spirit in which the new Maserati GranCabrio MC was conceived.

Mazda MX-5, 2013

 
 
 
  • Mazda , MX-52013

Powered by a 126 PS MZR 1.8-litre coupled to a five-speed manual or the 160 PS MZR 2.0-litre with a choice of automatic or manual six-speed transmissions, the facelifted Mazda MX-5 is introduced in Europe, starting in fall 2012.

The facelifted Mazda MX-5 is more fun to drive than ever. The latest version of the best selling roadster in history not only features more responsive acceleration and braking, but also an aggressive front-end design as well as enhanced pedestrian safety.

Mazda's technology specialists fine-tuned the acceleration management program (on manual shift models) to improve acceleration control and with it the linear response to throttle input, especially at lower speeds. By optimising the vacuum brake booster, meanwhile, they also enhanced brake return control. The upshot here is better handling thanks to superior front-rear load distribution. Drivers will appreciate these advancements most when braking into or accelerating out of curves. The Mazda MX-5, which has always excelled on winding roads, now reacts even more faithfully.

Preventing pedestrian injuries
The facelifted Mazda MX-5 is ahead of the curve in other ways, too. The new active bonnet system automatically raises the hood during an impact with a pedestrian, enlarging the crumple zone to prevent or at least diminish the severity of injuries, particularly to the head. The lower section of the front bumper has also been reinforced to better protect people's legs. The Mazda MX-5 is thus ready for stricter EU pedestrian safety standards.

When adding these safety features, designers also reworked the front-end of Mazda's legendary two-seater. The deeper grille and new bumper design express a lower, wider stance and a more assertive face, while the new fog lamp bezels and chin spoiler improve aerodynamics. Available as a retractable hardtop coupe or classic soft-top convertible, the new MX-5 comes in a choice of eight body colours including one stunning new option: Dolphin Grey. Inside, the glossy dark grey steering wheel spokes and panel décor provide a refined sporty optic.

McLaren MP4-12C Spider, 2013

 
 
 
  •  McLaren MP4-12C Spider, 2013

'The 12C Spider utilises all of McLaren's Formula 1 knowledge and expertise at building lightweight driver-focused sports cars. Just like the 12C, the 12C Spider is "pure McLaren" - it is built without compromise to offer maximum driving enjoyment and performance, but with the added appeal of roof-down driving. No other sports car has this combination of abilities.'

The new McLaren MP4-12C Spider, unveiled at the 2012 Pebble Beach weekend in California, is the second vehicle in the growing range of high performance sports cars from McLaren Automotive. This lightweight, mid-engine open-top sports car combines the astonishing performance of the 12C with the increased exhilaration of roof-down motoring. Unlike most other spiders or convertibles, the 12C Spider offers the same performance, handling and driver enjoyment as the fixed-roof coupé version.

The 12C Spider uses the industry-leading carbon fibre MonoCell as the 12C, which needs no extra strengthening to provide the necessary rigidity and strength for an open roof car. In conventional steel or aluminium chassis cars, extra strengthening - and associated weight increase - is normal during the conversion from fixed-head coupé to open-roof convertible. This can compromise performance, handling and driving enjoyment.

The composure of a sports car, the fun of a convertible
'In the new 12C Spider you get the best of both worlds,' says McLaren Automotive Managing Director Antony Sheriff. 'You get all the performance and driving integrity of the 12C, plus the thrill of open-roof motoring.

The new 12C Spider is mechanically identical to the 12C. It uses the upgraded 625PS engine, which is part of the 12C Model Year 2013 upgrade. Acceleration - 0-62mph (100 km/h) - takes just 3.1 seconds (when fitted with Pirelli P Zero Corsa tyres), the same as the coupé. Fuel consumption and emissions also remain the same, returning 24.2 mpg (11.7 l/100km) on the combined cycle and 279g/km. The figures are much better than most high performance convertible sports cars, in keeping with McLaren's commitment to class-leading fuel efficiency. Maximum speed is 204 mph (329 km/h).

The Retractable Hard Top (RHT) on the 12C Spider is a fully automatic two-piece design which can be raised or lowered in less than 17 seconds at speeds of up to 30 km/h (19 mph). When lowered, the roof stows beneath a body coloured hard tonneau cover which incorporates twin buttresses. With the roof raised, the area beneath the tonneau cover can be used as additional luggage space.

The 12C Spider features a heated glass rear window, which can be operated independently of the roof. With the roof down, the rear window moves automatically to an 'aero' position to minimise buffeting. Additionally, with the roof up, the window can be lowered to give direct access to the sound of the twin-turbo 3.8-litre V8 engine mounted directly behind the cabin.

A roll over protection system includes a steel structure within each of the rear buttresses to absorb any impact and protect occupants. An 'active' pop-up system was ruled out as it would have added weight.

The detail changes of the 12C Spider extend to both the audio and climate control systems. Audio output changes when the roof is open - to compensate for extra external noise - while the climate control adapts when the roof is lowered.

12C programme included Spider from the outset
'The 12C Spider is not a converted version of the 12C,' notes Sheriff. 'Importantly, the two were conceived and developed at the same time, and alongside each other. The 12C programme included a coupé and convertible from the outset. The carbon fibre MonoCell chassis and all other mechanical components were designed to produce maximum performance in both configurations.

'The 12C Spider fully subscribes to the McLaren overriding principle, that every single component should be 'Pure McLaren'. Each constituent part was conceived, designed and produced to McLaren specification - nothing is shared from other manufacturers. The goal is to maximise driving enjoyment, performance and efficiency. Just as important, we always seek to innovate. By producing the 12C Spider with all the performance, handling and ride quality of the 12C, we have done just that.'

12C SPIDER: THE DETAILS
As with the 12C, everything on the 12C Spider was designed for a reason. There is no unnecessary 'jewellery', no styling fripperies. It is a 'pure' sports car, designed to deliver maximum driving appeal and performance, with unmatched efficiency.

'As with all McLarens, the 12C Spider is a racing car at heart,' notes Design Director Frank Stephenson. 'That is not true of many - if any - other high performance convertibles.

'It has the same timeless elegant style that distinguishes the 12C but with the added romance of open-top driving,' adds Stephenson. 'We have tried very hard to preserve the same design purity. With the roof in place, it looks like a coupé sports car that could just as easily be at Le Mans, as in London or Los Angeles. With the roof down, it looks like it belongs on Sunset Boulevard or the Cote d'Azur.'

Retractable Hard Top (RHT)
The Retractable Hard Top (RHT) has been designed specifically for the 12C Spider. Low weight, combined with high strength, was of paramount importance - as with all areas of the 12C.

The two roof panels and tonneau are made from the same composite material used in the construction of the 12C body. This is light, strong and allows for a very high standard of paint finish. Heated rear glass completes the roof construction.

The fully automatic mechanism raises or lowers the roof in less than 17 seconds, and can be activated at speeds up to 30 km/h (19 mph). It is controlled by a two-position switch on the centre panel within the cabin.

At the end of the roof lowering cycle, the windows fully close, and the rear glass adopts an 'aero' position that also reduces cabin wind buffeting. Continuing to hold the switch after the cycle is complete fully lowers the windows and rear cabin glass.

The RHT is operated by a single hydraulic pump. It is mounted as low as possible in the vehicle to optimise the centre of gravity, and improve handling.

Dual-purpose tonneau cover
When lowered, the roof stows beneath a body coloured hard tonneau cover which incorporates twin buttresses. With the roof raised, the area beneath the tonneau cover can be used as additional luggage space. This can accommodate 52 litres of luggage in two specially designed bags, supplied as standard. This is in addition to the 144 litres of luggage space provided under the bonnet.

Retractable rear glass provides increased audible drama
The rear glass can also be operated independently of the RHT. Roof up, the rear glass can be lowered to allow more engine sound into the cabin and also allows for a semi-open driving experience even in inclement weather. Roof down, the screen acts as a wind deflector, minimising disturbance in the cabin.

Roll over protection system
A roll over protection system ensures maximum occupant safety. Each rear buttress contains a steel structure to absorb the impact energy and protect both driver and passenger. An 'active' pop-up system would have added unnecessary weight.

Carbon fibre MonoCell ideally suited for convertible use
As with the mechanically identical 12C, the 12C Spider is a mid-engine two-seat rear-drive high performance sports car. Unlike rivals, it uses a carbon fibre monocoque chassis, the MonoCell. This confers major advantages in weight, strength and torsional rigidity - all improving handling, ride comfort and performance.

The MonoCell is a unique one-piece moulded chassis that weighs just 75kgs (165lbs). It is 25 per cent stiffer than an equivalent all-metal structure and 25 per cent lighter than a comparable aluminium chassis (the difference with a steel chassis is even greater). It is also stronger and safer in a crash, acting as a safety survival cell, as it does in a Formula 1 car.

'It provides the perfect combination of occupant space, structural integrity and light weight,' explains Chief Engineer Neil Patterson. 'It is the ideal chassis to deliver groundbreaking efficiency and performance in the sports car market.'

The MonoCell is unchanged from 12C to 12C Spider, as it was originally designed for both applications. 'This is highly unusual,' notes Patterson. 'Most convertibles require a strengthened chassis to reduce flex, thus adding weight - while still not achieving the structural integrity of a coupé. This flex can compromise handling precision and reduce ride comfort; while the added weight affects performance.'

The carbon fibre MonoCell not only gives advantages in strength and weight, it also improves packaging. The one-piece moulded design has been created to provide the perfect cabin - roomy, yet compact. 'We started with the driver,' says Design Director Frank Stephenson. 'With the 12C and 12C Spider, the driver sits close to the centre line of the car, improving control and driver enjoyment. The pedals are positioned inboard, reducing wheel well intrusion. The result is the perfect driving environment- unique and uncompromised.'

The steering column is centred on the driver, and is parallel to his seat and shoulders. The brake and throttle pedals are both placed directly in line with the driver and all primary controls are within reach. The overall cabin architecture is both elegant in its design and uncluttered and intuitive to use.

As with the 12C, the 12C Spider has class-leading all-round visibility. 'Enormous emphasis was put on ensuring excellent visibility, both for safety and driving precision,' adds Stephenson.

McLaren: The carbon innovators
The carbon fibre MonoCell of the 12C and 12C Spider follows more than three decades of McLaren carbon innovation. In 1981, McLaren Racing introduced the carbon monocoque to Formula 1™. It offered an unbeatable combination of strength and weight-saving, and soon recorded the first victory for a carbon-based F1 car, at the British GP, driven by John Watson.

The legendary McLaren F1 road car, launched in 1992, was the first road car to use a carbon chassis and body. In fact, since 1981 McLaren has never built a car without a carbon chassis.

On the 12C and 12C Spider, aluminium extrusions and castings are jig welded onto front and rear structures and bolted directly to the MonoCell. Along with the carbon MonoCell, they carry the lightweight composite body panels. Apart from the roof, and the engine cover, body panels are identical to the 12C. A redesigned glass engine cover maintains an unobstructed view of the handsome twin turbo V8 engine.

'The front and rear aluminium structures are easy to repair,' adds Patterson. 'They absorb impacts and can be replaced easily. Cars with full aluminium chassis use their structure to absorb and crumple on impact, causing more damage and expense to the whole structure, including the passenger cell.'

Mercedes-Benz A45 AMG, 2014

 
 
  •  Mercedes-Benz A45 AMG, 2014

The A45 AMG sees Mercedes-AMG embarking on a new era. For the first time in the company's history extending back over more than 45 years, Mercedes-Benz's performance brand is offering a fascinating high-performance vehicle in the compact class. 

The basis for these impressive figures is provided by the high-tech package which has been put together by Mercedes-AMG.As a high-performance engine belonging to the BlueDIRECT family, the AMG 2.0-litre four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers. The combination of multiple fuel injection and multiple spark ignition improves fuel utilisation and increases thermodynamic efficiency substantially, leading to lower exhaust emissions.Other highlights include the gravity-die sandcast all-aluminium crankcase, weight-optimised crank assembly with forged steel crankshaft and forged pistons with friction-optimised piston rings, NANOSLIDE cylinder wall technology, air-water charge air cooling, generator management and ECO start/stop function.

The Mercedes-Benz A45 AMG is representative of the "AMG Performance 50" strategy for the future, which is to run up to the 50th birthday of Mercedes-AMG GmbH in 2017. With a maximum output of 265 kW (360 hp) and up to 450 Newton metres of torque, the AMG 2.0-litre four-cylinder turbo engine is the most powerful series production four-cylinder engine in the world. The sensational power density of 133 kW (181 hp) outstrips even the most powerful super sports cars. At the same time, the engine also boasts supreme efficiency and complies with the EU6 emissions standard.The A45 AMG also leads its segment in terms of fuel consumption, returning 6.9 litres per 100 kilometres (40.9 mpg) in NEDC combined mode. These credentials indicate that a further high-performing member of the BlueDIRECT family is now taking to the road.The performance-oriented AMG 4MATIC all-wheel drive onboard the A45 AMG sets new standards in the car's segment.

The substance of the new Mercedes-Benz vehicle architecture for front- and all-wheel drive provides the perfect basis for the A45 AMG and at least two other high-performance premium automobiles from Affalterbach. In designing and developing the Mercedes-Benz A45 AMG, the experts at AMG have drawn on the company's decades of experience in motorsport and the production of powerful, high-performance vehicles. As such, the A45 AMG will inherit the corporate DNA and embody the AMG brand claim "Driving Performance" to perfection: a fascinatingly sporty driving experience combined with impressive craftsmanship and pronounced individuality.

The most powerful series production four-cylinder engine in the world
Two figures show that the Mercedes-Benz A45 AMG holds pole position in its displacement segment: the newly developed AMG 2.0-litre turbo engine is the most powerful series production four-cylinder turbo engine in the world. A maximum output of 265 kW (360 hp) and up to 450 Nm of torque are unmatched by any other mass-produced turbocharged four-cylinder engine worldwide.

The power density of 133 kW (181 hp) is also absolutely unrivalled.In this discipline, the new AMG high-performance turbo engine even outstrips the most powerful super sports cars.

The high power and torque output and the combination with the performance-oriented AMG 4MATIC all-wheel drive lead to extremely dynamic performance: the A45 AMG accelerates from zero to 100 km/h (62 mph) in 4.6 seconds, while its top speed stands at 250 km/h (155 mph) [electronically limited].The specially developed AMG engine is also a model of efficiency - the Mercedes-Benz A45 AMG also leads its segment on this front, with fuel consumption of 6.9 litres per 100 km (40.9 mpg) in NEDC combined mode. This is accompanied by particularly low exhaust emissions:the A45 AMG already complies with the EU6 emissions standard which is not scheduled to enter into force until 2015, combined with the limit for the particle count per kilometre which will be mandatory from 2017.

Twin-scroll turbocharger and AMG sports exhaust system with exhaust flap
Mercedes-AMG addresses the essential challenges concerning the response of small-displacement turbo engines by means of a twin-scroll turbocharger, maximum derestriction of the exhaust system and an innovative injection strategy. The twin-scroll technology provides for a more spontaneous build-up of charge pressure, making effective use of exhaust gas back pressure, exhaust gas temperature and exhaust gas impulse. This results in a swifter build-up of torque right from the lower rev range.As a positive side-effect, the twin-scroll technology also benefits fuel consumption and exhaust emissions. At a maximum charge pressure of 1.8 bar, the AMG 2.0-litre four-cylinder turbo engine also leads the field in this respect.

The AMG sports exhaust system features large pipe cross-sections and an automatically controlled exhaust flap.This technology, which is familiar from the SLK 55 AMG, reconciles the two apparently conflicting aims of tangible dynamism and hallmark Mercedes comfort on long journeys.The flap is continuously adjusted by map control according to the power called up by the driver, load status and engine speed. The two striking tailpipes of the AMG sports exhaust system emit a fascinating, full engine sound which is particularly impressive during powerful acceleration.

An AMG Performance exhaust system with exhaust flap and featuring a dedicated tailpipe trim design is optionally available for the A45 AMG. This provides for an even more emotional and striking engine sound when the throttle is open and during gear shifting. The double-declutching function during downshifting and the interruption of ignition and injection during upshifting under full load produce a particularly throaty sound with the AMG Performance exhaust system and create a level of emotionality which is otherwise the reserve of engines with more than four cylinders.

High-performance cooling system with components from the SLS AMG
The highly capable driving dynamics of the A45 AMG call for a highly effective cooling system. On the basis of the components belonging to the SLS AMG, a low-temperature circuit is additionally deployed for air-water charge air cooling of the four-cylinder turbo engine. The large cooler section at the front level of the cooling module is supplemented by an additional cooler in the wheel arch. Together with the charge air cooler which is connected in series, a high-performance electric pump ensures the required flow through the water coolers located behind the large intake ports. This provides for ideal cooling of the highly compressed charge air, thereby contributing towards optimum engine performance.

Cooling of the transmission oil is integrated in the water cooling circuit for the engine. The water cooler positioned behind the front apron is supported by the heat exchanger which is fitted directly on the transmission and supplied with cooling water as required by means of an auxiliary pump.

Engine production - a tradition of hand-built excellence
Similarly to all eight- and twelve-cylinder engines, the new AMG 2.0-litre four-cylinder turbo engine is also hand-built according to the traditional AMG philosophy of "one man, one engine". An exclusive assembly line has been set up for the new AMG engine at the Mercedes-Benz engine production plant in Kölleda - where all BlueDIRECT four-cylinder engines are built for the A- and B-Class models. A characteristic feature of the "one man, one engine" production process is the AMG engine plate bearing the signature of the responsible engine fitter. Apart from serving as an AMG hallmark confirming superlative production quality, the AMG engine plate also attests to the peerless DNA of Mercedes-Benz's high-performance brand.

AMG SPEEDSHIFT DCT 7-speed sports transmission
Dual clutch transmission and all-wheel drive - the drive package onboard the new Mercedes-Benz A45 AMG is a demonstration of high-end engineering prowess.The AMG SPEEDSHIFT DCT seven-speed sports transmission is directly flange-mounted on the transversely installed AMG 2.0-litre four-cylinder turbo engine.Key software modules have been adopted from the SLS AMG super sports car with its inspirational power transmission concept. The dual clutch transmission of the A45 features seven gears, three driving programmes, a double-declutching function and RACE START for optimum acceleration. The strengths of the AMG DCT sports transmission include spontaneous gear shifting without any interruption in tractive power, a tailor-made control strategy, extremely smooth and easy gear shifting and a high level of efficiency. Reinforced gear wheels provide for maximum stability. Synchroniser rings with carbon-fibre friction linings improve durability while also optimising the response time during manual gear-changing - the ideal basis for ambitious laps on cordoned-off race tracks.

"Momentary M mode" for even greater dynamism and driving enjoyment
Another special feature designed to enhance dynamic performance and driving enjoyment is so-called "Momentary M mode". In C and S mode, this enables the driver to activate manual mode ("M") without having to remove a hand from the steering wheel, by pressing the "up" or "down" shift paddle once. In Momentary M mode the driver experiences the dynamism and performance of gear-shifting in manual mode in all of the automatic driving programmes, with automatic up- and down-shifting into the bargain.This allows the driver to devote his full attention to the vehicle's impressive performance.

The shift times in manual mode "M" and in Sport mode "S" are similarly sporty in character to those of the SLS AMG GT super sports car. Briefly and precisely interrupting ignition and injection under full load leads to even faster gearshifts with a more emotional sound than ever. In "C" mode (Controlled Efficiency), tangibly soft transmission and engine characteristics support a fuel-efficient and comfort-oriented driving style.The ECO start/stop function is also active in "C" mode.

Performance-oriented AMG 4MATIC all-wheel drive
The new A45 AMG comes with variable, performance-oriented AMG 4MATIC all-wheel drive as standard. In developing this all-wheel drive, the focus firmly was on performance and dynamism. The power flux to the rear powertrain is provided by a compact power take-off unit (PTU) which is fully integrated in the seven-speed sports transmission. It does not possess an oil circuit of its own. Instead, it is supplied with lubricant from the oil circuit of the sports transmission. This configuration gives rise to substantial weight advantages in comparison to rival systems which branch off power by means of an add-on component with its own oil circuit. Together with the friction-minimised tapered roller bearings, the PTU achieves an excellent level of efficiency. As an additional bonus, the system weight of the new AMG 4MATIC all-wheel drive is up to 25 per cent lighter than the all-wheel drive versions offered by the competition.

A two-part propeller shaft transfers the power from the AMG 2.0-litre four-cylinder turbo engine to the rear axle. In the interests of favourable weight distribution, an electrohydraulically controlled multi-disc clutch is integrated with the rear axle differential. The multi-disc clutch immediately detects slip at the front axle. A hydraulic pump instantaneously presses the discs together and channels the engine torque to the rear wheels as necessary. All this takes place virtually without the driver noticing. To enable particularly fast response, the pump is always active and does not need to be started up each time it is required, such as is customary with other systems. Power distribution is fully variable: in normal driving, the A45 AMG uses front-wheel drive in the interests of optimum efficiency. When the driving dynamics so require, the variable AMG 4MATIC all-wheel drive splits the torque between front and rear axle up to a ratio of 50 : 50. The variables influencing the power distribution ratio are vehicle speed, lateral and longitudinal acceleration, steering angle, speed difference between the individual wheels, selected gear and accelerator position.

Three-stage ESP® with ESP® Curve Dynamic Assist
An exclusive feature is the interaction of the AMG 4MATIC all-wheel drive with the three-stage ESP® and the ESP® Curve Dynamic Assist. The three ESP® stages enable the driver to vary the dynamics of the A45 AMG according to their individual wishes at the push of a button. The safety-oriented "ESP ON" mode supports the driver in maintaining neutral handling characteristics. The system initiates braking intervention on one or more wheels and reduces the engine torque on detecting that the operating conditions are becoming unstable.

Briefly pressing the ESP® button activates "ESP SPORT Handling" mode. This dynamically oriented driving mode applies appropriate control strategies for later ESP® intervention and increased drive torque at the rear axle. This means more fun at the wheel for drivers who are keen to exploit the vehicle's dynamic potential. Pressing the ESP®button longer activates "ESP OFF". In this mode, the ESP®functions are not available. ESP OFF should only be used by experienced drivers on cordoned-off race tracks. When the driver steps on the brake pedal in the course of braking in "SPORT Handling" mode or "ESP OFF" mode, all the safety functions of the ESP® system are restored.

ESP® Curve Dynamic Assist complements the ESP® system to perfection: during dynamic cornering, imperceptible braking intervention on the inside wheel gives rise to a defined yaw moment around the vertical axis, resulting in precise cornering by the Mercedes-Benz A45 AMG and ensuring that the vehicle remains under control at all times. Curve Dynamic Assist is adapted according to the selected ESP® mode.In "ESP SPORT Handling" mode and "ESP OFF" mode it supports the driver's wish for increased agility and driving dynamics. ESP®Curve Dynamic Assistis an additional function of the Electronic Stability Program which noticeably improves not only agility, but also active driving safety in critical conditions.

AMG sports suspension with independent front and rear axle
Like every AMG high-performance automobile, the new A45 AMG also incorporates sophisticated axle technology. For enhanced driving dynamics, the three-link front suspension is provided with stiffer steering knuckles and totally new elastokinematics. Newly developed, more rigid bearings are employed in the lower link plane. These provide for more agile cornering properties and more precise and direct feedback from the road surface. The more rigid bearings also lead to higher camber stiffness, enabling higher cornering speeds. In developing the complete front axle, great importance has been attached to attaining the best possible traction in highly dynamic driving.

The four-link rear axle of the A45 AMG is also a totally new development. In the course of optimising the elastokinematics, the strut bearings were duly adapted for maximum driving dynamics and control. The rear axle carrier is provided with more rigid bearings for increased driving stability; the subframe is rigidly connected to the body. The AMG sports suspension with specifically tuned spring/damper units and larger stabilisers provides for high lateral acceleration and a reduced rolling tendency in fast double bends. The Mercedes-Benz A45 AMG comes as standard with twin-spoke AMG light-alloy wheels, painted in titanium grey with a high-sheen finish, fitted with 235/40 R 18 tyres.

AMG speed-sensitive sports steering and AMG high-performance braking system
The electromechanical Dual Pinion AMG speed-sensitive sports steering with AMG-specific, speed-dependent power assistance and a constant steering ratio (14.5 : 1) enables high steering precision and agility. The electric motor is installed in space-saving configuration on the steering gear. The AMG high-performance braking system with ventilated and perforated brake discs all round in size 350 x 32 millimetres at the front and 330 x 22 millimetres at the rear provides for spontaneous and reliable deceleration.

Exterior design with sporty and muscular highlights
Mercedes-AMG adds emphatically sporty and muscular highlights to the emotional exterior design of the new Mercedes-Benz A-Class sporting the new dynamic style, sculptural character and feature lines on the sides. These refinements ensure that the A45 AMG looks the part as a distinctive high-performance automobile - a genuine AMG through and through.

The front view of the Mercedes-Benz A45 AMG is characterised by the AMG "twin blade" radiator grille and the cross strut in the AMG front apron, both painted in matt titanium grey. Striking black flics surround the large cooling air intakes at the sides. An interesting side view is guaranteed by the AMG light-alloy wheels in twin-spoke design and the side sill panels with inserts in matt titanium grey. The AMG rear apron with its highlighted air outlet openings at the sides features a diffusor insert and trim in matt titanium grey. Two square, chrome-plated tailpipes of the AMG sports exhaust system with exhaust flap add an appropriately bold finishing touch.

Dynamic and exclusive interior design and appointments
Inside, too, the new A45 AMG boasts a heady mix of hallmark Mercedes-AMG dynamism and exclusivity. The sports seats in ARTICO man-made leather/DINAMICA microfibre with red contrasting top-stitching, the multifunction steering wheel with shift paddles and the AMG DRIVE UNIT set new standards in terms of both appearance and quality. The dashboard trim comes in carbon-fibre look - a perfect match for the five air vents in black/red, the red seat belts and the AMG door sill panels. The AMG instrument cluster presents information by means of a central colour display with the AMG main menu and the RACETIMER.

Numerous individualisation options are available for the Mercedes-Benz A45 AMG (selection):
  • AMG Aerodynamics package: AMG rear aerofoil, additional flics in front apron, larger front splitter
  • AMG carbon-fibre exterior mirror housing
  • AMG Exterior Carbon-Fibre package: front splitter, side sill panel inserts and trim on rear apron in genuine carbon fibre

MG 3, 2014

 
  •  MG 3, 2014

MG has used the 2013 Shanghai Motor Show to preview the exciting new MG3 supermini, in advance of the UK and European launches in late 2013.

Carrying forward the styling cues first illustrated on the MG Zero concept vehicle, the new European MG3 is a distinctive statement of modern British style designed to target young and style conscious buyers, wanting something that's fun to drive and own.

This unique and contemporary style was brought to the super-mini segment by the design and engineering team at the MG Birmingham site in Longbridge, UK. The MG3 will become the second in a new generation of MG vehicles to leave the assembly line at the Birmingham factory.

At launch, customers will be able to personalise both the exterior and interior of this new supermini MG making it fun to buy and own, as well as the MG trademark of being fun to drive.

British Style fun
MG's UK-based design team have given the new MG3 a cheeky touch of flair from every viewing angle.

There is an echo of the fun and sportiness that lies at the heart of the MG brand. With a rear valance insert inspired by generations of MG racing cars, a unique superelliptic tail pipe finished in chrome and a body-coloured tail spoiler, the MG3 looks distinctly sleek and sporty - a designer's dream.

SPACE FOR FUN
Normally this is where the compromise comes on small sporty cars - but not with MG3. Fun, entertaining and easy to live with, the MG3 combines style and enjoyment with practical spaciousness. The designers and engineers have combined to create an exceptional amount of space and versatility in a very compact five-door package.

Extensive work from the MG Design and Engineering team on the architectural package has resulted in interior packaging that rivals or surpasses anything in its class. In a 4m long package, the MG3 will easily accommodate four 6ft individuals; a level of accommodation typically associated with larger cars that mirrors the spaciousness of the MG6 range.

The MG3's 'rolled and raised' front dashboard design creates an airy forward cabin space and increased legroom, while allowing excellent access to primary and secondary controls. This theme is continued in the rear of the car, where the front seats are sculpted to allow rear passengers excellent space to travel in comfort.

Class-leading rear headroom is another characteristic which sets the MG3 apart. Many cars in this sector compromise on interior space, particularly in the rear. But rear headroom in the MG3 is more than generous.

FUN BOY 3
Designed with the core value of being fun to drive, the MG3 chassis has been honed from hundreds of thousands of miles of testing on European roads. Intended to deliver impressive levels of body control, sharpness and a willingness to corner to engage keen drivers, MG's world class team of chassis engineers have also delivered sure footed handling and impressive ride comfort. Together this makes the MG3 suitable for every journey, from crowded urban routes, to flowing British B-roads or cruising on a European motorway.

MY MG3
In addition to a wide range of body colours a range of personalisation options will be available, allowing the MG3 to be tailored to the individual behind the wheel. Roof, side and bonnet graphics will allow owners to personalise their own MG3. Interior trims, wheels, vents, surrounds and mats will all be available in a choice of designs, colours and finishes allowing you to make your MG3 truly personal.

KEEP IT IN THE FAMILY
The new baby MG will be powered by a healthy 105PS version of the VTi-TECH petrol engine, joining the MG6 DTi-TECH and TCi-TECH engines in the European family. The dynamic and responsive VTi-TECH engine is mated to a 5-speed manual transmission that makes this little baby perfectly suited to nipping in and out of city traffic or enjoying a great British B road.

Mini Countryman ALL4 Camp, 2013

 
 
  •  Mini Countryman ALL4 Camp, 2013

The innovative roof-top tent is showcased above a MINI Countryman which, thanks to its intelligent all-wheel drive system ALL4, is well-suited to travelling over rough terrain. But this simple and practical sleeping solution can easily be mounted on a MINI or MINI Clubman. The upper half of the tent is simply folded out of its storage box. Plump up the pillows and two occupants are ready to relax, then wake up to a perfect view of the ocean, mountain or valley.

The roof-top tent quickly folds away into its box when it's not needed. The exterior has been painted in Absolute Black metallic with white stripes to match the car beneath.

Finding overnight accommodation can be a real headache, especially for drivers who have taken a spontaneous trip to a festival or beach. But there's no need to worry about finding the perfect place to bed down when travelling in this MINI. Even when completely off the beaten track, all the owner has to do is head upstairs.

How about an early morning ride out to buy breakfast? It's easily done because a mountain bike can be easily transported on the specially fitted bicycle rack.

Mitsubishi GR-HEV Concept, 2013

 
  •  Mitsubishi GR-HEV Concept, 2013

Beyond the specific one-ton pickup application, the addition of an electric motor to a Diesel engine brings further benefits:
    Instant response from the electric motor boosts Diesel engine accelerations.
    The motor also increases high-end torque of the Diesel engine.
    Quieter accelerations and high-speed cruising (within legal limits).
    Cleaner Diesel emissions.

Ever since it started R&D on electro-mobility back in 1966, today's Mitsubishi Motors Corporation (MMC) always considered that electric vehicles (EV) should eventually become long-term core products - a view vindicated by recent concerns over global warming.

From the pioneering i-MiEV in 2009 and a self-imposed objective of 20% of EV-based cars by 2020, MMC has already made significant steps in this direction as demonstrated with the all-new Outlander Plug-in Hybrid Electric Vehicle ("PHEV") and its most innovative "Dual Design" architecture.

Expanding further, Mitsubishi Motors now explores the full electro-mobility engineering palette - Pure Electric (EV), Hybrid Electric (HEV), Plug-in Hybrid Electric (PHEV) - hinted at through two concept cars world-premiered at the 2013 Geneva Motor Show, next to the New Outlander PHEV, one of which is the cutting edge GR-HEV Concept Sport Utility Hybrid Truck.

Going Hybrid
If electric vehicles are to have a significant impact on the environment, they should be able to attract a wide spectrum of customers with a full palette of EV-based vehicles across the range, from small runabouts to big SUVs, each using a dedicated application of the technology (EV, HEV or PHEV)

In this respect, New Outlander PHEV has already proved that EV powertrain and long-haul D-Segment crossover are perfectly compatible.

At MMC. the next logical step will be to expand further, adapting electric componentry to the demands of an even larger, tougher, sportier vehicle with both work and leisure in mind in either mature or emerging markets.

Such was the brief behind GR-HEV Concept, Mitsubishi Motors' inaugural take at Hybrid (HEV) technology, applied for the first time to a Mitsubishi one-tonne pickup truck, a format very much in demand in emerging markets and a Mitsubishi export best-seller, starting with Europe, its number one market (with over 615,000 units, out of the 1.42 million units exported from MMTh between 1992 and 2012).

Below 149 g/km
With this evocation of a possible next "Dual Design" vehicle, Mitsubishi Motors introduces an all-new proprietary HEV solution, featuring a 2.5 litre Mitsubishi Clean Diesel engine and a front-mounted electric motor, mated to an automatic gearbox - all controlled by an electronic operating system - as well as a battery pack located (and protected) within the ladder frame - further protection being provided by cross guard bars.

Simpler and more affordable than either EV and PHEV, HEV is deemed best suited to the heavy-duty daily requirements of pickup truck users and a perfect vector for MMC's green ambitions all the way to the most remote corners of the planet with an ambitious target for CO2 emissions below 149 g/km - far better than segment average.

The combination can also provide pure electric power on demand with available AC supply (100V~240V), to replace a generator or to allow the use of a 100V winch for instance, as well as the ability to drive over short distances in pure-electric mode.

GR-HEV Concept also uses Mitsubishi's renowned full-time 4WD technology, featuring Super All Wheel Control (S-AWC) integrated vehicle dynamics control system to deliver high stability traction and driving performance under all road conditions.

This HEV-dedicated driveline uses S-AWC to tailor output and braking to each wheel for every drive mode (2L, 4H, 4HL, 4LL) selected by the driver to help when facing difficult driving conditions:
    Safer, sure-footed all-terrain performance over mud, sand, snow-covered surfaces as S-AWC system leverages motor's instant response and controls braking force at each wheel.
    Torque regulation for instant response and excellent all-terrain performance.
    Improves stability when towing.

Cutting edge
Rugged, handsome and eminently usable, this 4WD Sport Utility HEV Truck show car was developed as a conceptual successor to a long line of one-tonne Mitsubishi Motors pickup trucks - from the original 1978 Mitsubishi L200.

All successful in their time, they always stood apart with their handsome design.

GR-HEV Concept continues with this tradition adding a strong dose of aerodynamic chunkiness while escaping the square-rigged look that seems to prevail in the segment.

On the contrary, over its long 5.42 m long dual-cab body, MMC Design produced a very muscular athletic shape, highlighted by a sharp blade-like character line, starting from the headlamps and progressing to form a very dynamic upswept beltline.

Carrying over a theme first developed for today's L200, GR-HEV Concept offers a total (pick-up) look whereby the long load bed is the visual continuation of the passenger cabin, simply delimited by a graphic J-shutline, itself serving as support to integrated running boards.

The load bed extends the 3D-sculptured shape of the cabin, whether in the wide open trapezoidal wheel arches (and their asymmetrical flat moulding, suggesting motion), in the shapely tailgate or in the helix-complex rear combination lamps. With their "scattered diamond" LED design, they give an impression of precision-cut jewellery and premium quality appearance of the tail.

Topping it up, the upper structure is no less dramatic with a low roofline highlighted by twin elongated satin-finished side mouldings. Arching over the cabin, they extend to flying buttresses over the backlight, connected by a twin-boom aerofoil. As a clear statement of (tough) intent, the integrated bed cover intersects sharply all the curves.

Front, the aerodynamic blades of the grille seem milled directly from solid brass as if to shield the Three-Diamond logo, in-between the sculptured wraparound diamond-shaped headlamps - an overall effect of width, stability and solidity.

Finishing touch, GR-HEV Concept rides on dynamically styled 3-spoke alloy road wheels using lightweight non-alloy spokes. Taking Mitsubishi's Three-Diamond corporate emblem as the design theme, they suggest strength.
