Lotus Evora S, 2011

The Lotus Evora S comes with a sport pack as standard featuring a 'sport' button which allows the driver to control throttle response and activate the exhaust by-pass valve. The sport button also raises the instantaneous rev limit and changes the dynamic stability control settings resulting in a total experience change. There are cross-drilled brakes for improved cooling. And here's a heads up for those who buy into the old adage 'you can tell the men from the boys by the size of their toys': the external emotion of the Lotus Evora S has been improved with a completely new active exhaust which means that at the push of a button the car sounds just as dramatic as it feels.

Commenting on the Lotus Evora S, Lotus Chief Commercial Officer Andreas Prillmann said: "The Evora S is a natural progression for us but more than that, it's a taste of what people can come to expect from the next generation of Lotus cars. It retains core Lotus values such as performance through lightweight but it also gives more than that. It's the perfect combination of top performance, style and comfort. Form doesn't sacrifice function in the case of the Lotus Evora S."

Jaguar XFR, 2012

 
 
 
 
 
 
 
Jaguar XFR, 2012

A saloon with the soul of a Jaguar sports car, the XF has won accolades and enthusiastic fans across the globe for its dynamic abilities and dramatic looks. Advances in lighting technology have allowed the new 2012 Jaguar XF model range to adopt the bold Jaguar design language introduced on the flagship XJ saloon.

Sheet metal revisions to the grille, bonnet and front wings incorporating new triangular side vents give the car a more muscular, purposeful appearance. The range-topping Jaguar XFR receives its own unique, overtly assertive design to underline its performance potential while an alternative 'Aerodynamic' option is available on all other derivatives for a total of three dramatically different styling options.

The headlamps now incorporate bi-function HID xenon technology that allows them to be much slimmer and more compact while still providing outstanding beam resolution. They also incorporate LED daytime running lights arranged in a distinctive Jaguar 'J-Blade' signature pattern for instant recognition.

The tail lamps have been entirely renewed and now extend onto the central portion of the boot lid. These new units are now full-LED for stop, light and indicator functions and give the Jaguar XF a distinctive night-time rear signature. Separating them is a revised boot lid finisher with a gloss black lower edge for a cleaner appearance. The boot also features power closure on all models.
Three new paint colours and an expanded alloy wheel selection ranging from 17 to 20-inch provide the finishing touches to the revised styling.

The Powertrain and Dynamics
Key among the enhancements to Jaguar XF is the introduction of the 2.2-litre AJ-i4D turbodiesel engine. The unit features low-friction pistons and a water-cooled turbocharger to increase efficiency plus active engine mounts and modifications to the sump and block to reduce NVH levels. The result is not only Jaguar's most fuel-efficient engine ever, but one which offers levels of refinement on a par with the previously-fitted 2.7-litre V6 diesel and all the performance expected of a Jaguar sports saloon. Further refinement is assured on all models by the use of additional acoustic shielding and the use of computational fluid dynamics to smooth exterior airflow.

Power output is 190PS with an impressive torque figure of 450Nm to provide the muscular performance expected of a Jaguar. Reaching 60mph in 8.0 seconds, the car will go on to achieve a top speed of 140mph. Nevertheless the unit still manages 52.3mpg on the EU combined cycle - making it the most economical Jaguar ever - and emits just 149g/km of CO2 and is Euro Stage V compliant.

The New 8-speed automatic
The engine is perfectly complemented by the all-new 8-speed ZF automatic gearbox. Specifically adapted by our engineers for its first-time application in a Jaguar, the transmission offers a host of benefits including both improved acceleration and economy. Gearchanges are completed in just 200 milliseconds - four times faster than the average human resting heartbeat - while driver control is enhanced by the ability to perform multiple downshifts using the paddleshift technology. The use of lightweight materials ensures the overall weight remains the same as the previous six-speed transmission, while improved pump design and gear control elements increase efficiency. Standard on all Jaguar XF diesel models, it reduces the CO2 emissions of the 3.0-litre V6 to 169g/km and improves fuel consumption to 44.8mpg.

The Intelligent Stop/Start
Also making its debut with the 2.2-litre diesel engine is Jaguar's new Intelligent Stop/Start system, the first time this technology has been seen in a premium diesel saloon. This automatically shuts down the engine in just 300 milliseconds when the car comes to rest, in order to improve fuel economy and CO2 emissions by between five and seven percent.

No driver intervention is necessary, with the engine management software analysing a host of complex factors in order to decide when the engine can safely be stopped. A Tandem Solenoid Starter with a dedicated secondary battery instantly restarts the engine as soon as the driver's foot leaves the brake pedal, ensuring it is running optimally by the time the accelerator is pressed. In order to facilitate this process, the gearbox features Hydraulic Impulse Storage, which supplies oil pressure to actuate the shift elements.

For the first time, all diesel variants are also available with Jaguar's Adaptive Dynamics system, allowing the enthusiastic driver to enjoy the car's outstanding chassis control and discover the Jaguar XF's sporting soul.

The Interior
Whether experienced from the driver or passenger seat, the cabin of the Jaguar XF is a uniquely welcoming and stylish place in which to spend time, using high-end materials in a truly contemporary manner.

Continuing to feature such dramatic 'surprise and delight' elements as the Jaguar Drive Selector that rises from the centre console and air vents that rotate to their open position when the starter button is pressed, the Jaguar XF interior has also received a comprehensive update.

New seats and instruments
Revised front and rear seats incorporate a 'hoop' feature on both squab and backrest that improves not only their appearance but also the support it offers by increasing the seat's profile. New hide colour combinations, veneers and headlining choices increase the personalisation options available to buyers. All models benefit from a revision to the colour scheme on the centre console, fascia and steering wheel where the 'Tungsten' finish is replaced by a more contemporary 'Aurora' theme.

The Jaguar XF incorporates a formidable amount of technology but in true Jaguar fashion it is integrated seamlessly into the function of the car and controlled through a central seven-inch Touch-screen with a new polarising filter for better contrast viewing.
In order to reduce driver workload, additional switches have been added below the Touch-screen to instantly switch between different functions while new graphics are based on those in Jaguar's flagship XJ. The main driver instrument cluster is now a full-colour TFT unit for greater resolution and clarity.

Cutting-edge technology
Three new audio systems are offered on the Jaguar XF, all of which represent a significant upgrade on those previously available. Heading this up is a 1200W, 17-speaker premium set-up, from British audio experts Bowers & Wilkins, which offers concert hall-like sound reproduction.

All audio systems can be specified with a hard-drive based satellite navigation system that incorporates a 'virtual' CD multichanger allowing the owner to 'rip' 10 CDs at a time into the car's memory storage and play them as if they were a physical music medium. The system also now offers a number of different options for connecting MP3 players; two USB ports, one of which is iPod specific and Bluetooth connectivity that allows music to be streamed from a smartphone.

The majority of the car's functions can also be controlled from the driver's seat by Jaguar's Interactive Voice functionality, which provides an intuitive interface for safe, hands-free operation.

Brabus SV12 R Biturbo 800, 2011

 
  
 
 

Brabus SV12 R Biturbo 800, 2011

The Brabus SV12 R Biturbo 800: 800 hp (788 bhp) / 588 kW and a peak torque of 1,420 Nm (1,047 lb-ft) transform the Mercedes-Benz S 600 in latest Brabus specification into the world's most powerful luxury sedan. But that's not all: With an electronically limited top speed of 350 km/h (217 mph) the exclusive four-seater also wins the 'Blue Ribbon' as the world's fastest luxury liner. Brabus rounds out the new high-performance standard with a sporty yet elegant designer suit, custom-tailored wheels with diameters of up to 21 inches, a high-performance brake system and customer-specific interior upgrades including a state-of-the-art "iBusiness" multimedia system with Apple components.

Twelve-cylinder high-capacity engines in the S-Class look back on almost two decades of tradition at Brabus. Powered by the SV12 R Biturbo 800 engine originally developed for the Brabus E V12 "one of ten" the automotive luxury class now attains a new level of performance.

Displacement of the V12 engine that normally powers the latest Mercedes 600 models is increased from 5.5 to 6.3 liters (336 to 385 cu. in.) The displacement increase is the product of a special crankshaft with longer stroke, precision-balanced piston rods, larger-diameter pistons and corresponding larger cylinder bore. The inner workings of the Brabus engine are modified further by high-performance camshafts and flow-optimized cylinder heads.

The new air intake was custom-developed to fit in the available space under the hood of the S-Class. The combustion air is routed through a special carbon-fiber system. Also newly developed was the Brabus Biturbo system with two special high-performance manifolds with integrated turbine housings and high-performance turbochargers. The system also includes four water-to-air intercoolers. The Brabus stainless-steel high-performance exhaust system with sport catalysts and four exhaust tips with Brabus-characteristic design optimizes power yield and gives the engine a more dominant exhaust note.

Newly calibrated engine electronics with precision-programmed mapping for injection and ignition ensure exemplary power yield and compliance with strict EURO V emission limits. The high-tech lubricants for the entire powertrain are supplied by technology partner ARAL.

The Brabus SV12 R Biturbo 800 engine produces 800 hp (788 bhp) / 588 kW at 5,500 rpm and an even more impressive peak torque of 1,420 Nm (1,047 lb-ft), available from a low 2,100 rpm. For technical reasons peak torque is limited electronically to 1,100 Nm (811 lb-ft).

Power is transferred to the rear wheels via a reinforced five-speed automatic transmission. A Brabus high-performance limited-slip differential with a locking rate of 40 percent is available as an option.

The extraordinary performance figures elevate the Brabus SV12 R Biturbo 800 to the exalted position of the world's most powerful and fastest luxury sedan. Acceleration times from 0 to 100 km/h (62 mph) of 3.9 seconds and of just 10.3 seconds to 200 km/h (124 mph) are as unmatched in this vehicle category as is the electronically limited top speed of 350 km/h (217 mph).

To ensure that this level of performance can be enjoyed safely at all times Brabus also significantly upgrades suspension, brakes and aerodynamics.

These upgrades naturally also include tires capable of handling the speeds this car is capable of. The Brabus SV12 R Biturbo 800 can be equipped with Brabus Monoblock wheels with diameters ranging from 19 to 21 inches. The largest version features wheels in size 9Jx21 on the front axle and in size 10.5Jx21 in the rear. These wheels are available in four distinct designs: Three-piece forged and high-gloss polished Brabus Monoblock VI wheels with six double spokes, multi-spoke Monoblock E wheels, Monoblock S wheels with double-spoke design and especially exclusive Monoblock F Platinum Edition forged wheels with cross-spoke design. All wheels are mounted with Pirelli or Yokohama tires in sizes 265/30 ZR 21 in front and 295/30 ZR 21 on the rear axle.

To further improve the already excellent driving dynamics of the high-performance luxury sedan Brabus developed an electronics module for the Active Body Control suspension that lowers the ride height by some 15 millimeters (0.6 inches).

Maximum deceleration is even more important than exceptional acceleration and thus the Brabus high-performance brake system is part of the high-tech package of the Brabus SV12 R Biturbo 800. The brake features 12-piston aluminum fixed calipers and 380 x 36-mm (15.0 x 1.42 inches) vented and cross-drilled discs in front, and 355 x 28-mm (14.0 x 1.1 inches) discs and six-piston aluminum fixed calipers on the rear axle.

Brabus ensures extremely high directional stability with a sporty yet elegant designer suit developed in the wind tunnel. The Brabus front fascia lends the S-Class an even more striking face while its sophisticated shape reduces lift on the front axle. The large central air inlet optimizes cooling of engine and front brakes. Integrated auxiliary headlamps and LED daytime running lights further improve active safety. The Brabus front spoiler lip is made from clear-coated carbon fiber and attaches to the underside of the Brabus front fascia. It further optimizes the car's aerodynamic properties.

For an even more extravagant appearance of the sedan Brabus offers custom-tailored aluminum front fenders that replace their production counterparts. The exclusive character of these fenders is embodied by an integrated air vent made from clear-coated carbon fiber and a horizontal brace that spans the vent with embossed Brabus signet and integrated LED lights. The latter are activated just like the ones in the Brabus side sills via the keyless remote or by pulling on a door handle.

For optimizing the airflow around the sides of the vehicle the designers sculpted Brabus sill skirts that feature integrated entrance lights for added utility. They are activated by the keyless remote or by pulling on a door handle as are the blue-illuminated Brabus logos integrated into the scuff plates on both sides of the vehicle.

The Brabus aerodynamic-enhancement concept is rounded out by the Brabus rear spoiler lip, also available in a clear-coated carbon-fiber version, and the new rear fascia with centrally located reflector and custom cutouts for the Brabus quad sport exhaust system. The underside of the rear fascia also features integrated LED lights which illuminate the ground behind the vehicle. They help avoid any unfortunate missteps into puddles or potholes lurking in the dark.

Brabus combines this high-performance technical feast with exclusive interior options that suit each customer's personal taste down to the last detail. These options include fully leather interiors in any color imaginable, Alcantara supplements and exclusive wood trim sets which can be ordered in any desired color thanks to an innovative staining technology.

A particular Brabus specialty is the creation of state-of-the-art multimedia equipment including the innovative Brabus "iBusiness" concept,

Hummer H3 Alpha, 2008

 
 
Hummer H3 Alpha, 2008

The towing capability that only a V-8 can, the 2008 H3 Alpha broadens HUMMER's range of versatile, do-anything and go-anywhere vehicles. HUMMER announced the H3 Alpha at the New York Auto Show; it goes on sale this summer.

The H3 Alpha is the second member of HUMMER's exclusive Alpha series, representing the pinnacle of performance, both off the road and on it. It comes with a new, 5.3L V-8 engine that delivers 295 horsepower (224 kW) and 317 lb.-ft. of torque (438 Nm). It is partnered with a four-speed automatic transmission and enables a maximum towing capacity of 6,000 pounds (2,721 kg) - an increase of more than 33 percent over other H3 models

In addition to the V-8 engine, the H3 Alpha also includes the popular "Luxury" equipment package, the Chrome Appearance package, 16-inch chrome wheels, a 4.10 rear axle ratio and special Alpha identification, including a prominent tailgate badge, horn pad badge and embroidered front headrests with the "Alpha" insignia.

The Alpha model can be combined with the H3 X content, which includes bright roof crossbows, chrome fuel door, a body-color grille and unique spare tire cover, tires, wheels and center cap, and a brush guard. Additionally, HUMMER Accessories offers an exclusive line of GM-designed, manufactured and validated accessories that are engineered and tested for no-compromises fit, finish and performance.

The Alpha - the ultimate HUMMER
HUMMER Alpha models represent the top in performance, capability and comfort. The H1 Alpha was the first of these ultimate HUMMERs, and like the H3 Alpha, it offered a more powerful engine as well as unique styling and comfort features.

The H3 is the newest model to carry the Alpha flag, and represents HUMMER's first Alpha model engineered in conjunction with GM Performance Division.

Award-winning interior and safety enhancements
The H3 Alpha shares the same widely admired interior as all H3 models, including detail revisions and enhancements that have been implemented across the lineup. New child safety locks for the rear doors and easier-to-use power window switches were introduced during the '07 model year and reflect customers' input.

The new for the H3 Alpha and the entire 2008 H3 lineup are standard head curtain side air bags; they were previously optional. Additional standard safety features now found on all H3 models:
  • StabiliTrak electronic stability control system
  • Four-wheel antilock brakes with traction control
  • Dual front air bags with Passenger Sensing System
  • Tire pressure monitoring system
  • Vehicle-to-vehicle crash compatibility
  • LATCH rear child seat anchors

HUMMER's Rear Vision system and a navigation system are available. The Rear Vision system uses a camera mounted near the rear bumper to provide a view of objects directly behind the vehicle. Also, the safety and security of On Star is standard, and its new Turn-By-Turn Navigation feature is available.

Powertrain details
The H3 Alpha's 5.3L engine is a powerful and efficient member of GM's legendary small-block V-8 family. It is rated at 295 horsepower (224 kW) and 317 lb.-ft. of torque (438 Nm); and is similar to the small-block V-8 found in the Chevy Silverado, which was named the 2007 Truck of the Year at the North American International Auto Show.

An aluminum cylinder block is used with the H3 Alpha's engine. It helps reduce overall mass and maintains a more desirable front-to-rear weight balance. Like all of GM's small-block V-8 engines, highlights:
  •     * Deep-skirt cylinder block with cross-bolted main caps
  •     * High-flow cylinder heads
  •     * Electronic throttle control
  •     * 58X ignition system
  •     * E67 32-bit controller
  •     * Polymer-coated pistons with full-floating wrist pins
  •     * Returnless fuel system
  •     * Lightweight valvetrain
  •     * Steel camshaft
  •     * Low-restriction air intake system

GM's small-block V-8 engines are engineered to meet today's more stringent emissions standards. In fact, the H3 Alpha's V-8 engine beats the deadline for new, U.S. federal emissions standards by a year. And compared to truck engines of a decade ago, the small-block engine family is approximately 90 percent cleaner. Cast iron exhaust manifolds matched with four close-coupled catalytic converters help reduce cold-start emissions, which is the largest source of vehicle emissions.

A Hydra-Matic 4L60 electronically controlled four-speed automatic transmission is paired with the H3 Alpha's V-8 engine. And, as with all H3 models, flat-towing is enabled.

New V-8 drives vehicle-wide enhancements
HUMMER H3 and GM Performance Division engineers did more than simply shoehorn a V-8 engine into the H3's engine compartment. Accommodating the new power plant necessitated the execution of a seemingly endless number of technical details - many of which have been implemented across the entire H3 lineup.

The H3's frame was modified to accept the V-8 engine, and a special oil pan was designed to ensure constant oil pressure when driving on steep grades - a hallmark of HUMMER's off-road capability. Also, the engine compartment front of dash was modified to accommodate the V-8, and a new steering system is used on all H3 models to deliver better on-center feel and even more improved off-road reliability.

To support the torque output of the powerful V-8, the H3 Alpha's front differential case is made of cast iron; other models feature an aluminum case. New engine mounts, higher torsion bar rates to support the increased mass, and specific shock valving also are unique to the V-8-powered model, ensuring it continues to deliver the unparalleled ride quality - both on- and off-road - that customers expect.
All of the chassis and suspension changes were validated in real-world testing on off-road trails in Moab, Utah, the Rubicon Trail and other challenging off-road venues.

A HUMMER by any measure
All H3 models pack HUMMER's trademark capability into a midsize package. Compared to the H2, the H3 is 16.9 inches (429 mm) shorter in length, six inches (152 mm) shorter in height and 6.5 inches (165 mm) narrower. Roughly the same length as a midsize family sedan, H3 comfortably navigates city traffic and fits nicely in parking garages.

The H3 lineup also delivers exceptional rock crawling and climbing performance; it was engineered for off-road leadership among midsize SUVs. The heart of this capability is its electronically controlled four-wheel-drive system and suspension tuning tailored for off-road performance. In addition, the H3 features standard underbody shielding, brake traction control, and an optional 4.03:1 transfer case with rear locking differential.

Among its off-road credentials, the H3 can ford 24-inch (610 mm) streams at a 5-mph pace, climb 16-inch (407 mm) vertical steps and rocks, make its way through deep sand and race easily over sandy surfaces.

H3's more maneuverable size provides advantages, such as a 37-foot turning circle that is about the same as a typical compact car, making easy work of parking lot maneuvers and tight turns when off-roading. The 9.1-inch (231 mm) ground clearance and maximum breakover angle of 25 degrees (with 33-inch tires) both make it possible to clear large obstacles in off-road driving. Serious off-road performance is also aided by the maximum approach angle of 39 degrees and maximum departure angle of 37 degrees. These approach and departure angles permit the H3 to drive into a hole and back out again, without getting hung up in the front or rear.

The H3 is sold in 34 countries, with production in the United States and South Africa.

Saturn Flextreme Concept, 2008

 
 

 Saturn Flextreme Concept, 2008

The Saturn demonstrates that clean, practical transportation and stunning can go hand-in-hand with the electric-drive Saturn Flextreme concept, introduced at the 2008 North American International Auto Show. Featuring breakthrough E-Flex electric propulsion technology that provides up to 34 miles of all-electric, emissions-free range, as well as a sleek, monocab, the Flextreme looks as clean as it drives.

With multiple aesthetic and functional innovations such as cameras that replace side-view mirrors and unconventional doors that allow easy entry and exit, Flextreme signals that the distinguishing features of Saturn's portfolio will continue in future product introductions: striking, European-inspired; and a commitment to providing customers with functional, efficient vehicles that respect the environment.

A collaborative effort between Saturn and GM's European Opel brand, the Flextreme concept was developed to showcase the future design direction of both brands, which share many similar customer traits. This design partnership has resulted in several highly successful production vehicles in the U.S. and Europe such as the Saturn Aura; the Saturn Sky and Opel GT; Saturn Vue and Opel Antara; and the Saturn Astra and Opel Astra. The Flextreme concept debuted as an Opel at the 2007 Frankfurt Auto Show.

The Flextreme also represents Saturn's ongoing commitment to deliver vehicles that use less fuel and produce fewer emissions. Unlike conventional vehicles and gas-electric hybrids, the Saturn Flextreme concept features GM's E-Flex System that uses an electric motor powered by a lithium-ion battery to propel it for up to 34 miles of electric-drive-only range. The battery can be recharged at a household outlet in just three hours. On the road, a clean and efficient 1.3L turbo-diesel onboard engine generates additional electricity to replenish the battery and extend the vehicle's driving range. Fully charged, the Flextreme's 34-mile, all-electric driving range is enough for most daily commuters in the U.S. to travel without using any fuel or emitting any CO 2.

Saturn's commitment to innovation and clean transportation is further illustrated by the two high-tech electric Segway Personal Transporters ingeniously packaged below the Flextreme's cargo floor. With a twist of the handlebar-mounted release, the handlebar retracts and rotates downward for easy loading into the rear compartment. Once docked, the batteries of these modified Segways can be charged along with the Flextreme's batteries.

Exterior design that dares to be different
The Saturn Flextreme concept highlights the new elements of Saturn design language: more sculpted surfacing molding, clear style elements such as narrow, boomerang-shaped lights and a sloping feature line in the side graphics.

The aerodynamic details and lightweight materials help enhance the fuel savings of the electric-drive system. For example, the bottom edge of the windshield is pulled far forward so that the hood, with its characteristic crease, is very short. The integrated power socket is in the cowl panel.

The front grille and rims are covered by lightweight, polycarbonate transparent trim, which improves aerodynamics while maintaining visual aesthetics. Special light alloy wheels look like conventional wheels, yet are designed to avoid energy-robbing air turbulence.

Like the wheel design, the large, boomerang-like curved front light units are visually deceptive, and continue a theme that began with the Opel GTC Concept at the Geneva Motor Show. The vertically oriented front lights "slice up" the front end in an unusual manner. The LED headlamp unit houses a lightweight crossbeam, fog lamps and air intake for brake cooling, which are comparatively small. The curved rear lights are completely integrated into the tailgate and hidden beneath rear glass. If one of the tailgate doors is opened, an additional parking light switches on so that the Flextreme can be easily seen in the dark.

All windows, including the windshield, are made of lightweight polycarbonate, as is a large part of the roof. The Flextreme's panoramic windshield provides a bright and spacious interior and stretches over most of the roof, which is reinforced by a spine-like composite structure that extends to the rear floor.

Innovative doors open up new possibilities
In keeping with Saturn's philosophy of challenging conventional thinking, the Flextreme concept design team set out to create a vehicle that combined GM's E-Flex chassis with a body style that is dynamic, yet efficiently makes the best use of space. To do so, it uses the Flex Doors and FlexLoad systems, two innovative, customer-focused solutions that enhance the Flextreme's functionality.

With the Flex Doors system, access to the rear cargo area is through two butterfly-style rear tailgate doors that individually swing open upward along the central axis of the vehicle. This thoughtful feature allows the Flextreme's trunk to be accessible from the side when parked tightly against a wall or another vehicle, or when a bicycle rack is fitted on the rear.

The rear doors are another key distinguishing feature of the Flextreme. While the front doors open in the conventional manner, the rear doors are rear-hinged. And as there is no center roof pillar (B-pillar), opening both doors on one side creates a large opening for easy entry. For families, this feature is especially useful when securing child seats and children into the rear seating positions.

High-tech interior features enhance convenience
The Flex Load underfloor luggage compartment may be the Flextreme's most customer-friendly feature. A practical yet flexible stowage option that extends and retracts electronically, it eliminates having to lift luggage up, over and into a trunk. In the Flextreme concept on display, the rechargeable Segway Personal Transporters are docked in this underfloor luggage compartment.

Also inside the Flextreme concept are honeycomb structures that offer low weight and high rigidity. These functional, geometric structures can be found in the instrument panel's lower portion, cabin floor, cargo floor and above the center tunnel where the lithium-ion batteries are located.

The seats use lightweight construction and are anchored to the car's floor by a single track rather than the usual two, creating more foot space in the rear. Refined upholstery gives the seats a light and elegant look, with some parts in fabric/mesh and corners made of especially soft material. The steering wheel hub houses another high-tech feature: a full-size driver air bag packaged with a special vacuum technique that reduces its overall volume.

Large, panoramic, configurable displays are set directly under the windshield. They can show a complete, all-around view of the car's surroundings, using the two side cameras (one front-facing, one rear-facing) that replace the conventional side mirrors. The displays can also show information about vehicle systems such as the audio system, phone and other equipment.

All the right touches
A second display on the center console features touch-screen operation. At the top, the programmable, one-touch buttons are designed like computer shortcuts. They provide easy access to various intuitive menus, including air conditioning, communication/infotainment and navigation functions. The buttons can be freely programmed and adapted to new infotainment systems. Further down is the Flextreme's touch-screen drive selector gate, with three driving positions: D, P and R (drive, park and reverse). The gears can also be comfortably selected via touch-screen control.

A clever storage system at the front and back of the center tunnel allows front and rear passengers to stow items such as mobile phones, MP3 players, iPods and PDAs in two drawers. The best part about this system is that the electrical devices can be recharged in the drawers by induction, and Bluetooth-capable systems can transmit their data to the onboard infotainment system.

E-Flex System reduces emissions, trips to the gas station
The Saturn Flextreme concept is part of GM's ongoing commitment to develop vehicles that reduce emissions and the automobile's dependency on petroleum. Unlike conventional vehicles and gas-electric hybrids, GM's E-Flex System uses an electric motor, powered by a lithium-ion battery, to propel the Flextreme for up to 34 miles of all-electric and emissions-free range. The on board engine creates additional electricity to extend the vehicle's driving range to a total of 444 miles (715 km).

GM has initiated production engineering for the E-Flex System. Production timing depends on continued advancement of key enabling technologies; specifically, the development of lithium-ion batteries for hybrid and electric vehicle applications.

While the featured fuel in Saturn Flextreme concept is diesel, GM's E-Flex System has previously been shown in gasoline and hydrogen fuel cell concepts.
