Cadillac CTS, 2014

 

 

 

•  Cadillac CTS, 2014

Cadillac introduced the all-new 2014 CTS sedan, which ascends into the heart of the midsize luxury market with expanded performance, elevated luxury and sophisticated technology.

The third-generation CTS sedan is based on the high-performing rear-drive architecture of the award-winning ATS sport sedan, moving Cadillac into the prestigious class of midsize luxury sedans. It will be the segment's lightest car, enabling the most agile driving dynamics in the class. A range of power-dense powertrains underpin its performance, including the all-new Cadillac Twin-Turbo engine and eight-speed automatic transmission.

A longer, lower and more athletic-looking proportion is introduced on Cadillac's landmark sedan and evolves the brand's Art & Science design philosophy. While growing five inches (127 mm) in length, including a 1.2-inch longer wheelbase, the roofline and cowl - the base of the windshield - are about an inch lower, dimensions that complement the longer exterior to accentuate the car's lean aesthetic.

While stretched in overall length and wheelbase, the all-new CTS sedan has a lower curb weight than the preceding model and weighs about 200 pounds (90 kg) less than the BMW 528i. Lightweight features, including Cadillac's first aluminum door structures, contribute to the lower weight and a nearly 50/50 weight balance. And for the first time on CTS, Magnetic Ride Control, Cadillac's real-time damping system, is available on base models.

Cadillac's shield grille and signature vertical lighting elements - including LED front signature lighting detail - evolve on the CTS. The grille is wider, with a more detailed texture, while the headlamps flow up with the hood line, incorporating crystalline LED light guides for a technologically advanced appearance with more uniform illumination.

Active grille shutters are included on some models, improving aerodynamic performance on the highway to enhance fuel efficiency.

Inside, a roomier, driver-centric cockpit interior with integrated technology and hand-crafted appointments complements the exterior elements and supports the Cadillac CTS sedan's driving experience. Eight available interior environments are offered, each trimmed with authentic wood, carbon fiber or aluminum. Leather seating is available, including available full semi-aniline leather, with hand-crafted, cut-and-sewn executions.

Cadillac CTS Performance
The new Cadillac Twin-Turbo V-6 and eight-speed automatic transmission combination leads the CTS sedan's powertrain lineup in the new CTS Vsport. It is the first twin-turbocharged engine ever offered by Cadillac and is the brand's first eight-speed automatic.

The CTS Vsport also features:

•     18-inch aluminum wheels with Pirelli summer-only performance tires (19-inch wheels with all-season tires are available)
•     A quicker steering ratio
•     Brembo disc brakes with aluminum calipers and high-performance brake pads,
•     Heavy-duty track cooling package
•     Driver-selectable track mode with specific steering rate and Magnetic Ride Control calibrations for greater track performance
•     Electronic limited-slip differential that enhances capability on the track - including optimal acceleration out of turns.

The Cadillac Twin-Turbo is SAE-certified at 420 horsepower (313 kW) and 430 lb.-ft. of torque (583 Nm), making it the most power-dense six-cylinder engine in the segment. A pair of smaller turbochargers helps provide more immediate power on demand, with approximately 90 percent of peak torque available from 2,500rpm to 5,500 rpm. That gives the engine a broad torque curve that customers will feel as strong, willing power in almost all driving conditions - and helps the CTS sedan reach 60 mph in an estimated 4.6 seconds.

The 2014 CTS is also available with a naturally aspirated 3.6L V-6 rated at an estimated 321 horsepower and also matched with the new paddle-shift eight-speed automatic in rear-wheel-drive models (or six-speed automatic with all-wheel drive; and a 2.0L turbocharged engine rated at an estimated 272 horsepower and paired with a six-speed automatic.

Cadillac's new, paddle-shift eight-speed offers efficiency and performance advantages over a six-speed transmission, including 1.5-percent greater fuel economy.

Excellent power-to-weight ratios and racetrack-honed suspension geometries established with the development of the ATS enabled engineers to advance CTS's performance with greater feelings of feedback, control and response. The comparatively low curb weight helps make the most of the driving experience by allowing the use of lighter-weight chassis components, which reduces unsprung weight to enable more precise handling without compromising ride quality.

The CTS sedan's low mass and optimal brake sizes are expected to give it braking performance that is among the best in the segment, with standard Brembo brakes.

Suspension and driver control highlights also:

•     Multi-link MacPherson strut suspension with a double-pivot design
•     Five-link independent rear suspension
•     Available all-wheel-drive
•     Premium electric, variable-assist power steering gear from ZF Steering Systems
•     Available Magnetic Ride Control real-time damping system
•     Choice of 17-, 18- and 19-inch aluminum wheels.

A number of aluminum components are used with the suspension system, while the rear suspension is mostly steel. That helps offset the weight of the engine and transmission at the front of the vehicle, helping the CTS deliver its near-perfect weight balance and contributing to less noise and vibration.

Cadillac CTS technology and safety
The CTS sedan seamlessly blends comfort, convenience and safety technologies with the interior's hand-crafted appointments and flowing design. Active safety features provide alerts and intervene when necessary to help avoid crashes.

At the core of the car's intuitive technologies is CUE, Cadillac's infotainment system that uses smartphone- and tablet-influenced controls and commands to access information and entertainment data. An eight-inch, high-resolution color touch screen with haptic feedback allows users to swipe and drag preferences. Bluetooth connectivity with natural voice recognition is standard with CUE, along with USB and SD card ports.

An available 12.3-inch high-resolution, configurable LCD instrument cluster display complements the CUE display and supports the active safety features. It offers drivers four layouts - from basic to performance-oriented - each delivering bold, crisp graphics tailored to the level of vehicle information desired. A full-color, configurable head-up display is also available.

Cadillac CTS technologies also:
    Cadillac's first 20-way adjustable front seats
    Motorized cup holder lid in the center console
    Heated and cooled (ventilated) front seats and heated steering wheel
    Electronically locking glove box
    Electronic park brake
    Adaptive remote start feature that also activates the climate control system
    Standard Bose eleven-speaker sound system and available Bose Centerpoint Surround Sound system with 13 speakers.

The new Cadillac CTS sedan is the first Cadillac to offer Automatic Parking Assist, which enables the car to park itself in parallel spaces. It uses ultrasonic sensors to locate a suitable space and maneuver the car into the space, with the driver only required to engage reverse and apply the accelerator and brake pedals. Ultrasonic rear park assist is standard.

Ultrasonic sensors, as well as radar and cameras, support the CTS's advanced safety features to help prevent crashes. Among the most sophisticated is Fr ont and Rear Automatic Braking , which relies on short-range radar technology and ultrasonic sensors to help the driver prevent front and rear low-speed collisions via a progression of alerts that extend to complete braking, if necessary.

A Driver Awareness Package includes Cadillac's patented Safety Alert Seat technology. It uses vibrating pulses in the driver's seat to alert the driver to an imminent collision or to vehicles in the car's blind spot. The seat vibrates on the left or right side, or both sides simultaneously, depending on the direction of the risk.

GM's first application of automatic safety belt tightening is offered in the new CTS. It automatically takes slack out of the safety belts when buckled and offers real-time, active adjustments during driving to ensure optimal tension and comfort. Additional available safety features:
    Full Speed Range Adaptive Cruise Control
    Panic Brake Assist
    Forward Collision Alert
    Automatic Collision Preparation (with brake prefill)
    Lane Departure Warning
    Side Blind Zone Alert
    Rear Cross Traffic Alert
    Rear Vision Camera With Dynamic Guidelines
    Adaptive Forward Lighting
    Active pedestrian protection system (in global regions where required).

The new Cadillac CTS sedan also features 10 standard air bags, including front-passenger dual-stage low-risk deployment, which makes the most of the air bag trajectory and inflation rate based on the occupant's size, position and severity of the crash.

Additionally, OnStar is standard for one year. It can use GPS and cellular phone technology to automatically call for help in the event of a crash. OnStar service also includes myCadillac and OnStar myCadillac mobile apps, whichoffer vehicle information, controls and OnStar services via the customer's iPhone or Android smart phone.

Chevrolet Camaro Z28, 2014

 

 

 

•  Chevrolet Camaro Z28, 2014

The new Camaro Z/28 is not intended to compete in a specific race series, it is solely focused on track capability. In initial testing, the Camaro Z/28 is three seconds faster per lap than the Camaro ZL1. That extra speed comes from three areas:

•     Increased grip: The Z/28 is capable of 1.05 g in cornering acceleration, due to comprehensive chassis revisions
•     Increased stopping power: the Z/28 features Brembo carbon-ceramic brakes capable of 1.5 g in deceleration, and consistent brake feel, lap after lap
•     Reduced curb weight: The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1, with changes ranging from lightweight wheels to thinner rear-window glassChevrolet introduced the restyled 2014 Camaro line at the 2013 New York Auto Show, including the return of the Z/28, the most iconic model in Camaro history.

The Camaro models feature a revised exterior design that integrates high-performance aerodynamics for more efficient cooling and stability at high speeds. The new Chevy Camaro Z/28 also features a full aerodynamics package that creates downforce at speed, which helps make it the most track-capable offering in Camaro's history.

The first Camaro Z/28 was introduced in 1967, created to compete in the Sports Car Club of America's Trans-Am 2 class. It featured a smaller, lighter, 302-cubic-inch V-8 for improved weight balance, as well as quick-ratio steering and a heavy-duty suspension for track use. In keeping with its road-racing focus, the 1967 Camaro Z/28 was not available with an automatic transmission or air conditioning.

Like the original, the 2014 Chevrolet Camaro Z/28 is offered only with a manual transmission. In a nod to modern convenience, air-conditioning is available, but only as an option.

The new Camaro line will arrive at Chevrolet dealers later in 2013. The Camaro Z/28 is expected to be appearing at track events across the United States in spring 2014.

High-performance aerodynamics highlight changes for 2014 Camaro

The Camaro represents the most significant redesign since the introduction of the fifth-generation Camaro as a concept car in 2006.

Compared to the previous model, the design represents a strong visual change front and rear, resulting in a wider, lower, more contemporary appearance. The front fascia features a wider lower opening, and a narrower upper opening that also updates the appearance of the iconic "halo ring" HID headlamps on the Camaro RS package. The functional hood vent on the Camaro SS helps reduce heat and aerodynamic lift. Moving to the rear, the sculptural decklid, horizontal lamps and diffuser complete the powerful statement.

The Camaro Z/28 also features a full aerodynamic package designed to produce downforce at track speeds. At the front, the Z/28 features a large splitter, connected to an underbody panel that further reduces lift. In profile, the Z/28 features fender flares over the front and rear wheels, as well as extended rocker panels that contribute to aerodynamic stability. An aggressive rear spoiler and functional diffuser complete the aerodynamic package.

On the interior, the Camaro Z/28 features trim in a distinctive, matte-metallic finish named Octane, the ZL1 flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. The new seats (also available on the coupe versions of the SS and ZL1 models), feature aggressive bolsters for high-performance driving, as well as seat cutouts inspired by the five-point harnesses found on racing seats. To save weight, both front seats incorporate manual adjustment.

The rear seats of the Z/28 have also been modified for weight reduction. A total of nine pounds (four kilograms) was saved by eliminating the seat-back pass through, as well as using high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom.

7.0L, LS7 the heart of the Camaro Z/28's track-capable performance

Like the original, the new Chevrolet Camaro Z/28 forgoes ultimate horsepower and torque for improved weight balance and track performance.

In 1967, the most-powerful engine available in a factory Camaro was a 396 cid V-8 with 375 horsepower. To prepare the Camaro Z/28 for road racing, engineers specified a lighter, 302 cid V-8, officially rated at 290 horsepower. While the 302 was not the choice for drag racers, it proved ideal for sports-car racing.

The most-powerful engine offered is the Camaro ZL1's supercharged 6.2L LSA, which delivers 580 horsepower. The heart of the 2014 Camaro Z/28 is the lighter, naturally aspirated 7.0L LS7 first introduced in the Corvette Z06.

Co-developed with Corvette Racing, the hand-assembled 7.0L (427 cid) V-8 uses a number of high-performance components:

•     Titanium intake valves and connecting rods, and sodium-filled exhaust valves
•     CNC-ported aluminum cylinder heads
•     Forged-steel crankshaft and main bearing caps
•     High-lift camshaft
•     Hydroformed exhaust headers
•     11.0:1 compression ratio, and a 7,000 rpm redline.
•     10.5-quart, dry-sump oiling system

For the Camaro Z/28, the LS7 features unique induction and exhaust systems, and delivers at least 500 horsepower (373 kW) and 470 lb-ft of torque (637 Nm).

The racing-style, cold-air induction system and large K&N air filter provide maximum air flow.

The standard dual mode exhaust system and larger-diameter pipes enable improved air flow. By bypassing the mufflers during acceleration, the system increases both the torque and sound generated by the LS7 engine.

The Camaro Z/28 is exclusively offered with a Tremec TR6060 manual transmission. The six-speed features close-ratio gearing and 3.91:1 final drive ratio, both optimized for the power characteristics of the LS7.

Power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by continuously adjusting the torque bias to maximize available traction.

The differential works in unison with Chevrolet's proprietary Performance Traction Management system, which allows drivers to adjust the level of throttle and brake intervention to match their capability and driving environment.

Unlike some competitors' "track package" offerings, the Camaro Z/28 makes standard all the cooling systems required for track use. This includes the dry-sump oiling system for the LS7, which is connected to an integral liquid-to-liquid cooling system for engine oil.

A second liquid-to-liquid system provides cooling for the transmission and differential. This system pumps overcooled transmission fluid to a heat exchanger in the rear differential before traveling to the transmission. This reduces differential temperatures as much as 100 degrees F.

Camaro Z/28 chassis delivers 1.05 g in cornering grip
The singular focus of the Camaro Z/28 is most evident in the chassis, where the most has been made of every component for track use, from the ultra-high performance tires to race-proven dampers.

The Camaro Z/28 is the one of the first production cars fitted with race-proven, spool-valve dampers. Compared to a conventional damper that offers only two-way tuning for bump and rebound, a spool-valve damper allows four-way adjustment to precisely tune both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range allowed engineers to dramatically increase the damper stiffness on the Camaro Z/28 without a significant change in ride quality. Additional chassis changes include stiffer string rates and suspension bushings for improved cornering response.

The Chevrolet Camaro Z/28 features 19-inch diameter wheels and tires, which reduce unsprung weight by 42 pounds (19 kilograms) per car compared to the 20-inch wheels standard on Camaro SS and ZL1. In addition, the smaller diameter wheels lower the center of gravity by 33 millimeters, further improving handling.

At all four corners, the lightweight, forged aluminum wheels are wrapped in massive 305/30ZR19 tires. This is the first production application of ultra-high performance Pirelli PZero Trofeo R tires, and believed to be the widest front tire on any production car.

To fully exploit the grip of the Pirelli tires, the Camaro Z/28 also features Brembo Carbon Ceramic Matrix™ rotors and fixed, monoblock calipers. The large 394 x 36 mm front rotors are paired with six-piston calipers, while the 390 x 32 mm rear rotors are paired four-piston calipers. Compared to similar-size, two-piece steel rotors, the lightweight carbon discs save 28 pounds (12.5 kilograms) per car.

The combination of tire grip and braking power enable the Camaro Z/28 to achieve up to 1.5 g in deceleration. With standard front brake cooling ducts, the Z/28 is also capable of continuous track use unmatched brake feel, lap after lap.

Extensive lightweighting saved 300 pounds over the Camaro ZL1
To optimize the track performance of the Camaro Z/28, the engineering team subjected it to an intensive lightweighting program, saving 100 pounds (45 kilograms) compared to the naturally aspirated Camaro SS and 300 pounds (136 kilograms) to the supercharged Camaro ZL1.

Other examples of weight savings:

•     Eliminated the tire-inflator kit, except for Rhode Island and New Hampshire, where it is required by law
•     Removed interior sound deadener, and carpeting from the trunk
•     Replaced the standard LN4 battery with a smaller, lightweight, LN3 battery
•     Specified thinner, 3.2-mm glass for the rear window, compared to 3.5-mm glass on the standard Camaro
•     HID headlamps and foglights are not available
•     Air conditioning is only available as a stand-alone option

Audi A3 Sportback g-tron, 2014

 

 

 

•  Audi A3 Sportback g-tron, 2014

The A3 Sportback g-tron can fundamentally run on natural gas, the biomethane on sale at certain filling stations, or e-gas. Customers wanting to buy e-gas can sign up for a particular contingent of e-gas for the A3 g-tron at their Audi dealer. This enables them to take part in an accounting process that ensures that the amount of gas that they put in their vehicle at the natural gas filling station has been supplied to the grid by the Audi e-gas plant.

Audi is taking a large step towards sustainable future mobility with the A3 Sportback g-tron. The five-door premium compact model, which will appear on the market at the end of the year, runs on both the fossil fuel natural gas and on climate-friendly Audi e-gas, which Audi itself produces at a recently completed power-to-gas plant. It innovatively combines ecological balance, economy and high-tech solutions.

The Audi A3 Sportback g-tron, the brand's first natural gas car to go into production, reveals the sheer depth of the technological expertise of Audi - from ultra lightweight technology through the highly advanced infotainment to the driver assistance systems. It showcases state-of-the-art CNG technology (CNG = compressed natural gas), complete with the fuel storage technology. Its two pressurized tanks beneath the trunk floor each hold around seven kilograms (15.43 lb) of gas; they essentially use the recess for the spare wheel, thus impinging only minimally on the load capacity.

These tanks, which store the gas at a pressure of 200 bar, use the ultra lightweight construction principle of Audi: They weigh 70 percent less than conventional steel bottles, each of them weighing 27 kilograms (59.52 lb) less than an equivalent steel version. Their composition reveals an innovative layout: The inner layer consists of a gas-impermeable polyamide matrix, while a second layer of carbon fiber reinforced polymer (CFRP) gives the tank its extremely high strength; a third layer of glass fiber reinforced polymer (GFRP) provides protection against damage from the outside. Epoxy resin is used to bind the fiber reinforced materials.

A second highlight of the Audi A3 Sportback g-tron is its electronic gas pressure regulator. This compact and lightweight component reduces the high pressure of the gas flowing from the cylinders down to around five to nine bar in two stages. It ensures that the right pressure is always present in the gas rail and at the injector valves - low pressure for efficient driving in the lower speed range, and higher when the driver wants more power and torque.

When the pressure in the tank falls below 10 bar when there remains about 0.6 kilogram (1.32 lb) of gas, the engine management automatically switches to gasoline operation. The Audi A3 Sportback g-tron is designed as a bi-fuel concept. In the NEDC cycle it drives over 400 kilometers (248.55 miles) on gas and a further 900 kilometers (559.23 miles) on gasoline, so its overall range is comparable to a TDI. The driver information system always shows current consumption; two displays in the instrument cluster indicate the tanks' fuel level. The filler pipes for both are located behind the same flap.

After refueling, and whenever it is very cold, the Audi A3 Sportback g-tron is started with gasoline initially, then it is switched over to natural gas as quickly as possible. Its engine is a modified 1.4 TFSI; the cylinder head, turbocharger, injection system and catalytic converter are specifically designed to run on gas. With an output of 81 kW (110 hp) and 200 Nm (147.51 lb-ft) of torque, the compact five-door model accelerates from 0 to 100 km/h (62.14 mph) in less than 11 seconds; it achieves a top speed of more than 190 km/h (118.06 mph).

The Audi A3 Sportback g-tron is the benchmark in its segment for efficiency and economy. Its CO2 emissions in the exhaust gas remain below 95 grams per km (152.89 g/mile) in the NEDC cycle, and the fuel costs for the customer are around four euros per 100 km (62.14 miles). Over 100 km (62.14 miles), the compact car uses on average less than 3.5 kilograms (7.72 lb) of natural gas or Audi e-gas - the fuel that is produced in the Audi e-gas project from CO2 and water using renewable power. This fuel is a major step into the future of mobility for the brand with the four rings - Audi is the first carmaker to be establishing production facilities for a whole chain of sustainable energy sources.

The e-gas plant that Audi has set up in Werlte (Emsland) involes two major process stages - electrolysis and methanation. In the first step, the plant uses renewable power to break water down into oxygen and hydrogen in three electrolyzers. The hydrogen obtained from this process can be stored separately if required, for powering future fuel-cell vehicles.

However for the time being, in the absence of an area-wide hydrogen infrastructure a second process step is carried out: The hydrogen is then reacted with CO2 to produce synthetic methane, or Audi e-gas. In chemical terms it is almost identical to the fossil fuel natural gas and can therefore be distributed throughout Germany using the natural gas grid to CNG filling stations, for refueling vehicles.

The carbon dioxide used in the Audi e-gas plant is waste gas from a nearby biomethane plant that runs on organic waste and is operated by power utility EWE. That plant separates it from the crude biogas to produce highly pure biomethane. The Audi e-gas plant is expected to achieve an annual output of around 1,000 metric tons, capturing around 2,800 metric tons of CO2 that would otherwise pollute the atmosphere. As a result, the fuel is climate-neutral.

Throughout the entire production process at the e-gas plan that Audi has erected jointly with the plant engineer ETOGAS (formerly SolarFuel), the efficient use of energy flows is a high priority. The waste heat that is given off during methanation is put to good use in sanitizing the waste and preparing the biogas, appreciably increasing overall efficiency. The Audi e-gas plant is currently being commissioned and from summer 2013 will be supplying the grid with synthetic gas.

Audi e-gas is a high-energy fuel that is ideal for powering combustion engines. The CO2-neutral e-gas from Werlte can power 1,500 new Audi A3 Sportback g-tron vehicles, each driving 15,000 kilometers (9,320.57 miles) a year. In operation, these cars do not produce a single gram of CO2 that has not previously been captured during the e-gas production process. Even in the comprehensive well-to-wheel calculation, which includes the outlay for building and operating wind turbines and the e-gas plant, current forecasts predict the CO2 equivalents to remain under 30 grams per km (48.28 g/mile).

The German energy industry as a whole stands to benefit from the Audi e-gas concept. There is still the unsolved question of how to store renewable power, of which there is an increasingly frequent oversupply following the energy policy rethink, efficiently and independently of location. The world first of linking power with the gas grid as demonstrated by the e-gas project in Werlte offers a solution to this problem by storing the e-gas produced in the natural gas grid, the biggest and most efficient form of energy storage available. This prospect could provide a major boost to the expansion of renewable energies.

Audi A3 Sedan, 2014

 

 

 

•  Audi A3 Sedan, 2014

The A3 Sedan launched in spring 2013, Audi is entering the world's largest market segment, the class of compact sedans. The dynamic four-door car offers all of the strengths of the A3 model series - with low weight thanks to lightweight design, powerful and highly efficient engines and numerous high-end solutions for infotainment as well as driver assistance systems. The top model of the series is the S3 Sedan with 221 kW (300 hp).

The exterior design
The Audi A3 Sedan has a sporty stance on the road, and it is precise and highly expressive in every detail. Its design is a cross between the classic three-box concept and the coupé philosophy. The "tornado line" design element forms a distinct light-refracting edge that runs over the entire side. The overhangs are short. The four-door car has a 2.64 meter (8.66 ft) long wheelbase and an overall length of 4.46 meters (14.63 ft).

Above the side sills, the dynamic line rises more sharply than on the other two A3 models. The side surfaces are more intensively curved, and the wheel arches are slightly more flared. With a width of 1.80 meters (5.91 ft), the A3 Sedan is eleven mm (0.43 in) wider than the A3 Sportback; its height (1.42 meters [4.66 ft]) is still nine mm (0.35 in) lower than that of the Sportback.

The four-door car also expresses independent lines in the contour of its hood, in the bumpers, air intakes and its implementation of the singleframe grille. At the rear, the spoiler is integrated in the trunk lid, and the lights emphasize the car's horizontal lines with their broad and low cuts. LED technology is available as an option. Audi will also be offering full-LED headlights right at market launch - their innovative technology and distinctive appearance underscore the exceptional positioning of the Audi A3 Sedan.

Body
With a 1.4 TFSI engine, the sedan has a curb weight of just 1,250 kg (2,755.78 lb). Audi uses many hot-shaped steel parts in the passenger compartment for low weight and maximum strength, while the engine hood is made of aluminum. The body is very rigid, crash-safe and quiet.

The strict dictate of lightweight design carries over into the interior and the engines as well. The four-cylinder engine weighs just over 100 kg (220.46 lb).

Powertrain
When the Audi A3 Sedan launches in Germany and Europe, the engine line-up will consist of three four-cylinder engines. Completely redesigned, the engines bring together efficiency technologies from Audi - direct fuel injection, turbocharging, innovative thermal management and the start-stop-system. The line-up of engines and transmissions will grow further, and will include two new basic engines.

The 2.0 TDI produces 110 kW (150 hp) and develops 320 Nm (236.02 lb-ft) of torque. It accelerates the Audi A3 Sedan from 0 to 100 km/h (62.14 mph) in 8.7 seconds and takes it to a top speed of 220 km/h (136.70 mph). Its combined fuel consumption is 4.1 liters per 100 km (57.37 US mpg) - for a CO2 equivalent of 108 grams per km (172.20 g/mile).

Key performance parameters of the 1.4 TFSI are 103 kW (140 hp) and 250 Nm (184.39 lb-ft). At low engine load, the COD (cylinder on demand) system deactivates two cylinders. The 1.4-liter engine gives the car a combined fuel consumption of just 4.7 liters fuel per 100 km (50.05 US mpg); its CO2 emissions are 109 grams per km (175.42 g/mile). It takes just 8.4 seconds to accelerate from 0 to 100 km/h (62.14 mph), and the car's top speed with this engine is 213 km/h (132.35 mph).

The 1.8 TFSI produces 132 kW (180 hp) and 250 Nm (184.39 lb-ft) of torque. It utilizes an extensive package of high-end technologies, including dual injection into the combustion chambers and the induction manifold. It enables sporty performance, taking 7.3 seconds for the standard sprint to 100 km/h (62.14 mph) and reaching a top speed of 235 km/h (146.02 mph). Its combined fuel consumption is 5.6 liters per 100 km (42.00 US mpg), equivalent to 129 grams CO2 per km (207.61 g/mile).

Depending on the engine, either a manual six-speed transmission or the S tronic is used. The dual-clutch transmission shifts the gears without any noticeable break in propulsive power. It is controlled by either the selector lever or paddles on the steering wheel.

The D shifting map is laid out for maximum fuel efficiency, while the rev levels are somewhat higher in the sporty S mode. In cooperation with the Audi drive select vehicle dynamics system, the S tronic offers a free-wheeling function in its efficiency mode which further reduces fuel consumption.

Chassis
The pole position that the Audi A3 Sedan has enjoyed in its segment is largely due to its chassis engineering. Providing the foundation here is a finely balanced axle load distribution (60 percent front and 40 percent rear, varies somewhat for different engines). All engines are tilted twelve degrees towards the rear, while the front wheel suspensions are placed far forward.

The front suspension is a MacPherson design with A-arms and aluminum pivot bearings. It is joined to an aluminum subframe. The electromechanically assisted steering system operates sensitively and efficiently together with various assistance systems. In the four-link rear suspension, which utilizes a steel crossmember, the springs and shock absorbers are mounted separately. The sport suspensions for the Ambition line and S line lower the body by up to 25 mm (0.98 in).

The Audi A3 Sedan has 16- to 18-inch-wheels; quattro GmbH can also deliver wheels up to 19 inches in diameter. The front brake discs are internally ventilated.

Electronic stabilization control or ESC also includes an electronic differential lock. In fast driving through curves, it brakes the inside front wheel very slightly to minimize understeering and improve traction.

Interior
The interior of the Audi A3 Sedan is characterized by impressive attention to detail. The lines and surfaces are cleanly designed, and a long arc spans the width of the windshield. The instrument panel with its curved front is slender, and the center console is slightly turned towards the driver. The optional color display of the driver information system (DIS) shows images in highly detailed 3D graphics.

Starting with the MMI Radio system, the MMI operating system has an electrically extending screen. Its terminal is housed in the console of the center tunnel. The electromechanical parking brake is activated by a pushbutton. The steering wheel has either three or four spokes, depending on the version. The customer can also order the steering wheel with a flat bottom, multifunction keys and shift paddles. Audi can also install sport seats in the front as an option. They are standard in the Ambition line, where S sport seats with integrated head restraints are available as an option.

The interior colors - black, titan gray, pashmina beige and chestnut brown - are based on the specific equipment line. The two-tone Audi design selection lasso brown creates an exclusive color world. The S line sport package, which can be ordered for the A3 Sedan Ambition, immerses the interior space entirely in black. Available upholstery materials include fabric covers, a mix of fabric and artificial leather, Milano leather and a combination of Pearl nappa leather and Alcantara.

Thanks to the long wheelbase, rear passengers also enjoy ample space and comfortable entry. The cargo capacity of the trunk measures 425 liters (15.01 cubic feet). This capacity can be increased by folding down the rear seatbacks which come with a load-through hatch as an option. The trunk lid automatically swings upward after it is unlocked.

Infotainment and Audi connect
Like its siblings in the model series, the Audi A3 Sedan makes use of the new modular infotainment system (MIB). The top system is MMI Navigation plus with an SSD hard drive offering 64 GB of storage, a DVD drive and whole-word voice control. A high-resolution 7-inch-screen shows the map image in detailed 3D graphics. The MMI Navigation plus system interfaces to cell phones and mobile players via Bluetooth. The user terminal has a turn/push control designed as a "touchwheel" with MMI touch - the touchwheel's top surface is a touch-sensitive pad for inputting letters, symbols and numbers.

Other infotainment components include a module for digital radio reception (DAB+), the Audi phone box for conveniently coupling a cell phone to the car antenna and the Bang & Olufsen sound system. Its 705 watt amplifier drives 14 loudspeakers in 5.1 surround sound, and LED light guides illuminate the woofer grilles in the front doors.

Audi connect covers all technologies that network the driver with the car, the Internet, infrastructure and other vehicles. Audi has made the system even more appealing - whenever possible the connection to the Internet is run over the super-fast LTE standard. The LTE telephone module replaces the previous UMTS module here, which enables a download rate of up to 100 MBit/s in the car.

Audi connect lets passengers conveniently surf and e-mail via an integrated WLAN hotspot. For the driver, it brings customized Internet services from Audi into the car. They range from navigation using images from Google Earth and Google Street View to Audi traffic information online and the smartphone app Audi music stream. News and information services complete the line-up. The online community services Facebook and Twitter are integrated in a vehicle-friendly way; along with a text-to-speech function, a practical text function is provided with prepared text units.

A new Audi connect service that is making its debut in the A3 Sedan is parking space information. It shows information on parking spaces, parking garages and underground garages near a destination selected by the driver. Whenever possible, the service indicates the number of available spaces and parking fees. The street address of the parking space can be used as a navigation destination.

Features
The new Audi A3 Sedan is launching with a generous set of standard features. The package of restraint systems includes a knee airbag for the driver. The DIS with color display in the Ambition and Ambiente lines includes an efficiency program, gearshift indicator and rest recommendation feature.

In addition, the Ambition line has a sport suspension, 17-inch-alloy wheels, sport seats and the Audi drive select system. The Ambiente line adds a cruise control system, interior LED lighting package and rear parking assistant. In addition to these standard features, Audi also offers other individual comfort and convenience options - such as a panoramic glass sunroof, convenience key, auxiliary heating and xenon-based adaptive lights. In conjunction with MMI Navigation plus, the lighting system utilizes route data to optimally illuminate the roadway depending on the driving situation.

Optional driver assistance systems also come from the premium class. The adaptive cruise control (ACC) maintains a desired distance between the A3 Sedan and the vehicle in front of it up to a speed of 150 km/h (93.21 mph); with the assistance package, which combines multiple systems, the control range is extended up to 200 km/h (124.27 mph). When combined with S tronic, ACC also offers a stop&go function for low speeds.

The rear radar sensor Audi side assist monitors lane changes, while Audi active lane assist helps the driver to keep within the lane by making slight corrections to the electromechanical steering as necessary. The video camera of Audi active lane assist is also used for traffic sign recognition. A high-end solution for convenient parking is park assist with display of the surroundings - it relieves the driver of steering work in parallel and perpendicular parking maneuvers.

Another high-end option is the safety system Audi pre sense basic. Pre sense front is integrated in the adaptive cruise control system. In case of an imminent rear-end collision, the system warns the driver using a staged reaction strategy; if necessary, it can even initiate hard braking. In an emergency situation at speeds under 30 km/h (18.64 mph), Audi pre sense front can brake the A3 Sedan with nearly full braking power. If a crash occurs, the brake assist system avoids secondary collisions by ensuring that the car does not travel further in an uncontrolled manner.

Market
With the A3 Sedan, Audi is entering the world's strongest market segment, the class of compact sedans.
In Germany and many European countries, the four-door car will be available at dealers late summer 2013. The base price for the 1.4 TFSI is around 25,000 euros.

Audi A3 Cabriolet, 2014

 

 

 

 

•  Audi A3 Cabriolet, 2014

The quattro drivetrain operates with an electronically-controlled hydraulic multi-plate coupling. The body was lowered 25 millimeters (0.98 in), and 17-inch brakes are mounted behind the 18-inch wheels. 19-inch wheels are also available in conjunction with Audi magnetic ride. Progressive steering is standard.

Sporty, elegant and multi-faceted - Audi presents the new A3 Cabriolet. The compact four-seater impresses at first glance with its flowing lines and soft top. It is also at the top of its class technically - with systematic lightweight design, new engines, multi-faceted networking and high-performance assistance systems.

The soft top
The new A3 Cabriolet has a soft cloth top that is stretched over a lightweight kinematic mechanism made of magnesium-steel, and it complements the car's design perfectly. At the press of a button, the top opens or closes electro-hydraulically in less than 18 seconds, even while driving up to 50 km/h (31.07 mph). In the opened state, the top - folded into three layers - rests in a tray that barely affects luggage capacity, which is 287 liters (10.14 cubic ft).

The fully automatic soft top has a glass rear window and is offered in Black as standard. A fully automatic acoustic top is available as an alternative; it has a thicker inner foam layer which reduces the already low interior noise level of the Audi A3 Cabriolet even more. The acoustic top is available in the three exterior colors of Black, Gray and Brown, and its roofliner is available in black and lunar silver. A wind deflector is standard for the Ambiente trim line, and head-level heating is an option for the front seats. An active rollover protection system protects the occupants in case of a rollover accident. It consists of two spring-loaded plates that are recessed into the body.

The Exterior design
The new Audi A3 Cabriolet has grown compared to the previous model: its length increased from 4.24 to 4.42 meters (13.91 to 14.50 ft), its wheelbase from 2.58 to 2.60 meters (8.46 to 8.53 ft) and its width from 1.77 to 1.79 meters (5.81 to 5.87 ft). Only its height (1.41 meters [4.63 ft]) was reduced by 15 millimeters (0.59 in). This gives the four-seat convertible a more elegant and sporty look on the road. Luggage capacity grew by 60 liters (2.12 cubic ft), and it is easier to load. The wheel housings can handle wheels up to 19 inches in size.

The front of the Audi A3 Cabriolet is characterized by the Singleframe radiator grille. The flat headlights give it a resolute look; they emphasize the horizontal styling and the air intakes in the bumper. Audi offers headlights with LED technology as an option; they are the only LED headlights in the compact segment to offer variable headlight leveling control.

The rear overhang plays a key role in the harmonious proportions of the two-door car. The windshield frame is made of aluminum - and an aluminum-look trim strip runs around the entire car. On the flanks, the design features a taut tornado line and contoured sheet metal surfaces that create a fascinating interplay of light and shadow.

Body
In the base version, the car's curb weight is just 1,365 kilograms (3009.31 lb) - the new Audi A3 Cabriolet is around 50 kilograms (110.23 lb) lighter than the previous model despite its larger size and better comfort. Including its special reinforcements, which deliver high torsional stiffness, the body-in-white weighs 30 kilograms (66.14 lb) less than previously; the engine hood is made of aluminum. Weight was also significantly reduced in the interior and in the engines. This let Audi - a pioneer in this technical field - set an impressive best value in the compact class. Customers can choose from 16 different exterior paints for the body.

Interior
Elegantly drawn lines and clean surfaces also typify the interior design of the new Audi A3 Cabriolet. The instrument panel is lean and low, its front is slightly curved, and the center console is angled slightly towards the driver. The large, round air vents in jet design, the control panel for the air conditioner and the three-dimensional trim strips bring premium class elegance into the interior. The optional lighting package includes a touch-sensitive switch for the reading lights - a feature being offered for the first time.

As in every Audi, workmanship quality is uncompromisingly high, and the car's controls are simple, intuitive and convenient. It offers enough space for four adults, and the seatbacks of the two rear seats can be folded down which opens up a wide through-load area. The steering wheel and seats are new designs, and the also new electro-mechanical parking brake is operated by a pushbutton on the center console.

The trim lines are named Attraction, Ambition and Ambiente. The S line sport package for the Ambition line immerses the interior space entirely in black. Customers can choose cloth, leather or Alcantara/leather upholstery materials. The Audi design selection lasso brown conveys an exclusive look.

Assistance systems
Driving in the new Audi A3 Cabriolet is even more impressive with its highly developed assistance systems. The driver information system with efficiency program and attention assist are already standard features on the Ambition and Ambiente lines. The options program includes adaptive cruise control, Audi side assist, Audi active lane assist, camera-based traffic sign recognition, park assist with selective display and various feature levels of the Audi pre sense safety system.

Also extremely attractive is the line-up of infotainment components; at the very top are the Bang & Olufsen sound system and MMI Navigation plus. The super-slender seven-inch monitor extends from the instrument panel electrically. The user terminal has a rotary/push button control that is designed as a touchwheel with MMI touch - the touchwheel's top surface is a touch-sensitive pad for inputting alpha and numeric characters.

The Audi connect concept aims to network the driver with his or her environment. In the new Audi A3 Cabriolet, this function - which supplements MMI Navigation plus - provides a connection to the Internet, and whenever possible via the fast LTE transmission standard. The integrated WLAN hotspot lets passengers use their mobile devices to surf and e-mail freely.

The system brings Internet services from Audi connect into the car for use by the driver - from navigation with Google Earth images and Google Street View to online traffic information and services such as Facebook and Twitter. The latest service from Audi connect is parking information; it shows available parking spaces in parking and underground garages and parking lots.

Drivetrain
The three newly developed engines being offered in the Audi A3 Cabriolet at its launch all emphasize the car's sporty character. The two TFSI engines produce 103 kW (140 hp) and 132 kW (180 hp) from 1.4 and 1.8 liters of engine displacement, respectively. The 2.0 TDI develops 110 kW (150 hp); Other engines will follow - ranging from the 1.6 TDI with 81 kW (110 hp) to the 2.0 TFSI, which will power the Audi S3 Cabriolet with 221 kW (300 hp). All engines in the new Audi A3 Cabriolet combine the technologies of direct injection, turbocharging and a start-stop-system.

On average, the three engines offered at market launch have twelve percent better fuel economy than the engines in the previous model - and they do so while improving driving performance. The 1.4 TFSI, for example, accelerates the new Audi A3 Cabriolet from 0 to 100 km/h (62.14 mph) in 9.1 seconds, yet its combined fuel consumption value is 5.0 liters fuel per 100 kilometers (47.04 US mpg) and its CO2 emissions are 114 g/km (183.47 g/mile). Also contributing to this efficiency is Audi cylinder on demand (COD) technology, which deactivates two of the engine's cylinders in low load conditions.

The new Audi A3 Cabriolet also features state-of-the-art technology in power transmission. At its launch, the 1.8 TFSI is being offered with a seven-speed S tronic; together with the Audi drive select vehicle dynamics system, it offers a free-wheeling function that further improves fuel economy. The 1.4 TFSI and 2.0 TDI are each paired with a manual six-speed transmission. This will be followed by the quattro all-wheel drive system - another new feature and USP of the compact Cabriolet.

Chassis
The chassis of the new Audi A3 Cabriolet impresses with sophisticated technology that delivers sporty handling, superior vehicle safety and a high level of comfort. Some of the components of the MacPherson front suspension are made of aluminum; the four-link rear suspension handles longitudinal and transverse forces separately. The power steering system features an efficient electromechanical drive.

The ESC stabilization control system integrates an electronic limited slip differential - this makes handling even smoother and safer at the vehicle's cornering limits while driving fast through curves. The brakes are powerful and durable. Wheel sizes range from 16 to 19 inches, and tire sizes range up to 235/35. Two versions of the sporty chassis are offered; the sport suspension lowers the body 15 millimeters (0.59 in), while the S line sport suspension is 25 millimeters (0.98 in) lower.

High-end options in the new Audi A3 Cabriolet include the Audi drive select vehicle dynamics system (standard on the Ambition line). The driver can use this system to modify engine management, power steering, S tronic and air conditioning operation over several modes. This control also extends to optional systems such as the adaptive suspension control system Audi magnetic ride, adaptive cruise control, adaptive light and progressive steering whose steering gear ratio becomes increasingly more direct when turning.

The new Audi A3 Cabriolet will come off the assembly line at Audi's plant in Gyor, Hungary, which Audi has expanded with an investment of more than 900 million euros. Sales begin this autumn in Germany, and first deliveries will be in the first quarter of 2014. The base price for the 1.4 TFSI (103 kW with cylinder on demand technology) is 31,700 euros. Many sporty and comfort/convenience options round out the standard features; they include the deluxe key and S sport seats with integrated head restraints and diamond topstitching in the shoulder area.

Audi S3 Cabriolet (preliminary data)
In the top S3 version, which will follow shortly after the car's initial launch, the compact Cabriolet delivers very sporty driving performance. The 2.0 TFSI engine produces 221 kW (300 hp) and transfers 380 Nm (280.27 lb-ft) of torque to the crankshaft. With a six-speed S tronic, the car completes the sprint from 0 to 100 km/h (62.14 mph) in 5.4 seconds. The combined fuel consumption of the four-cylinder turbo is 7.1 liters per 100 kilometers (33.13 US mpg).
