Audi A6 Le-tron Concept







Audi is presenting its first luxury-class e-tron concept car - a technology study known as the Audi A6 L e-tron concept at Auto China 2012 in Beijing. The plug-in hybrid has a powerful drive system that enables a driving range of 80 km (49.71 miles) on pure electric power, and it was specifically designed to fulfill Chinese needs.

                      The A6 L e-tron concept is an important step towards future electric mobility in China for Audi. With its first e-tron technology study in the luxury class, the company is showing what a locally produced New Energy Vehicle from Audi might look like.

                     The basis for this study is the new A6 L, the most successful premium automobile and Audi's bestselling model in China. Audi produces this business sedan at the Changchun plant in a joint venture with FAW.

                     The A6 L e-tron concept is precisely tailored to the requirements of Chinese customers. Plug-in hybrids that can travel long distances electrically - thereby enabling zero emissions driving in local areas - are ideal for use in rapidly growing megacities. Beyond its drive system, the A6 L e-tron concept has all of the qualities that customers value in Audi cars: prestige, comfort and sporty performance.
 
                   The technology study is a parallel hybrid. It brings together a 2.0 TFSI that outputs 155 kW (211 hp) and an electric motor with 70 kW (95 hp) peak power. The liquid-cooled lithium-ion battery is located in a collision-protected space at the rear of the vehicle. In electric mode, the Audi A6 L e-tron concept can travel up to 80 km (49.71 miles) at a constant speed of 60 km/h (37.28 mph). At any given moment, the hybrid control module chooses the best suited operating mode with the focus on driving range.

                   This technology platform can be operated with only the internal combustion engine, only the electric drive, or in hybrid mode. In addition, it can recover energy during deceleration, or it can boost output power for strong acceleration by combining the two drives. The Audi A6 L e-tron concept delivers sporty performance.
The rapid advance in urbanization and the associated need to reduce CO2 emissions are a key determining factor for new drive technologies. Audi views electric mobility as a key future technology and is working on highly efficient solutions that simultaneously offer the customer a typical Audi driving experience.

                    Audi has already launched electrified drive systems in volume production with full hybrid models that have highly advanced lithium-ion technology. The Q5 hybrid quattro, A6 hybrid and A8 hybrid can drive up to three kilometers (1.86 miles) on electric power. In combined mode, which uses the internal combustion engine and electric motor, customers experience sporty driving performance and significantly better fuel economy.

                     The next step is to implement drive systems in which electric driving is the primary focus. The term Audi e-tron refers to technologies ranging from PHEV (Plug-in Hybrid Electric Vehicle) to range extenders and finally vehicles powered purely by electric batteries or fuel cells.

                 In its first Audi e-tron concept car, Audi already showed how this future might look. And in the case of the R8 e-tron, this vision will be realized in a short production run later this year.

                    Audi is using A1 e-tron and A3 e-tron test vehicles to acquire important customer feedback, which can be incorporated in later production cars. The first product will be the A3 e-tron in 2014. It will be followed by other New Energy Vehicles. In this way, e-tron will become established as a further attractive drive technology option alongside TDI and TFSI.

                    The Audi A6 L e-tron concept is notable for its elegant styling. The sedan, which has a 3.01 meter (9.88 feet) wheelbase, is 5.02 meters (16.47 feet) long and 1.87 meters (6.14 feet) wide, but only 1.46 meters (4.79 feet) tall. Its long engine hood, its low, extended roof line and the sharp lines on its sides create an athletic overall look. Characteristic Audi LED headlights emphasize the car's determined expression.

                     The car's exterior styling shows its differences from the production car. At the front, the single-frame grille with its slender cross-bars and the nearly covered air intakes attract the eye - both features are typical of all e-tron models. Powerful 21-inch wheels in e-tron design and the special rear diffuser highlight the car's progressive character. On the body, signatures identify the prototype's technology, while under the engine hood a styling capsule covers engine components. A ribbed contour at its center symbolizes the hybrid drive.

                        The body of the A6 L e-tron concept is identical to that of the Audi A6 L. It is lightweight, rigid and safe to a maximum degree, due to application of the ultra lightweight principle. Consisting of approximately ten percent aluminum, it weighs about 15 percent less than a comparable all-steel design. Aluminum components in the load-bearing structure and exterior skin, as well as the high-tech steels used in the occupant cell, make the body significantly lighter.

                            Each new future Audi model will be lighter in weight than the previous model. This makes the brand a frontrunner in reversing the upward weight spiral. In designing car bodies, developers will intelligently use new combinations of materials, including carbon fiber-reinforced polymer (CFRP). For Audi, ultra lightweight construction does not solely focus on one material, rather it seeks a flexible approach that utilizes a wide variety of materials - but with one goal: to attain the best performance with the least material usage at the best places.

                           Furthermore, advanced materials and construction methods achieve an extremely low sound level in the interior of the Audi A6 L e-tron concept. Excellent vibration comfort is attained by fine-tuning components and by hydraulically damping axle and drive mounts.

                          Audi's ultra lightweight construction competence is also found in the chassis, which combines a high level of comfort with sporty handling. The links are made of aluminum. The power steering, like the brake booster and the air conditioning compressor, utilizes an electromechanical drive.
At the limits of performance in driving through curves, the electronic transverse differential lock - a function of electronic stabilization control (ESC) - stabilizes the Audi A6 L e-tron concept by making small interventions at the front wheel on the outside of the curve.

                         The controls are intuitive. The powermeter replaces the tachometer; its pointer indicates total drive system power on a scale of zero to 100 percent. Colored segments indicate the current operating state of the A6 L e-tron concept; an auxiliary instrument visualizes the charge state of the lithium-ion battery.

                      Meanwhile, the energy flow indicator tells the driver the current operating mode and which hybrid drive components are currently active. It can be called up from the driver information system or MMI monitor. The large screen shows a bar diagram of average fuel economy and indicates the amount of recovered energy over five-minute intervals.

                       The Audi A6 L e-tron concept offers a lot of space at all seating positions. It integrates all of the model line's luxury-class features. The seats offer ventilation and massage functions, the Bose surround system delivers good sound, and the deluxe automatic air conditioning system with air ionizer ensures a pleasant climate in the car. Ambient lighting adds subtle highlights to the interior illumination.

                      The driver assistance and safety systems also satisfy the highest standards. Audi active lane assist supports the driver in lane-keeping, while Audi side assist helps to change lanes. When it is dark, the night vision assistant highlights detected pedestrians even at a distance; the parking assistant helps in parking. The Audi pre sense system can reduce the severity of accidents and their consequences in many cases.

                         The car's features also include MMI navigation plus. Many functions of the large hard-drive navigation system can be controlled by touchpad character input; the touch-sensitive pad, MMI touch, recognizes 29,000 Chinese characters. A team of engineers developed these functions at the Audi Infotainment Tech Center (ITC) in Beijing, where infotainment components from Germany are adapted to suit the wishes of Chinese 
customers..

Audi A5 DTM





Model change in the DTM: From 2012 on, Audi will bank on the A5 in the most popular international touring car racing series. The coupe, which is internally named "R17," will replace the four-door A4 DTM with which Audi has won the prestigious DTM title four times since 2004.







The technically and visually upgraded A5 that will be arriving at dealerships shortly provides the basis for the new DTM car. 



"In 2012 new Technical Regulations will come into effect in the DTM," says Head of Audi Motorsport Dr. Wolfgang Ullrich. "We've got exactly the right model for that in the A5. We're convinced that we'll be able to continue Audi's success story with it in the DTM."



The new technical specifications have been worked out by the German Motorsport Association (DMSB) and the DTM umbrella organization ITR in close cooperation with the automobile manufacturers and are setting new standards particularly in terms of safety. "Our engineers have been involved in bringing up safety in the DTM, which had already been high before, to the highest possible level," explains Dr. Ullrich. "At Le Mans this year we learned again that our concept of designing safety structures is a very good and appropriate one. This is exactly what we've been trying to feed into the DTM's safety concept together with our colleagues from BMW and Mercedes-Benz. This new principle is an outstanding example of what is possible when employees of three premium manufacturers try to achieve a common aim: to get the best possible, lowest-cost and safest vehicle - and a fantastic car in general - off the ground."


Like all new DTM cars, the new Audi A5 DTM has a high-strength carbon-fiber monocoque that is combined with a steel tube cage. In addition to the A- and C-pillars the new regulations prescribe a B-pillar in front of the driver's head to be installed in the future. The sidewalls of the vehicles feature a hybrid design with a carbon, Zylon and Rohacell construction that is structurally reinforced by pegs. In case of a side impact the walls have to be able to withstand a static load that is about four times higher than before. "The sidewall has been reinforced so that the new DTM vehicle can be exposed to a side impact (T-bone crash) without the wall failing," explains Dr. MĂĽhlmeier, Head of Technology at Audi Sport. "Up to now, a bearable side force of 80 kN at a specified point has been required whereas for the 2012-specification vehicles 360 kN across the whole length of the sidewall is now required. This means that the monocoque has not only been reinforced at a certain point but across the entire length."


The requirements for the front and rear crash absorbers have been increased as well. "At higher speed lower deceleration is specified in order to protect the driver even better than before," says Dr. MĂĽhlmeier. "To achieve this, a crash test with the whole vehicle is now prescribed for the first time as well - according to FIA standards with 14 meters per second forward and backward against a rigid wall. In the past, 'only' the front and rear crash elements had to be driven against a wall with a sled."


Although fire accidents have almost never occurred in the DTM the safety standard in this respect has been raised even further as well. In the new generation of DTM cars the fuel tank, similar to the Le Mans winning Audi R18 TDI, is integrated into the carbon fiber monocoque. This further reduces the fire hazard in case of a side impact crash.


For Audi the new DTM regulations mark a consistent continuation of the work done over the past three decades. The rally cars already had a high level of safety. For the supertouring cars Audi Sport developed a completely new side impact protection of carbon fiber and energy-absorbing foam in the middle of the nineteen-nineties. Ever since Audi has had sports prototype commitments crash tests and work with high-strength carbon composite materials have been part of its routine business. And for the R8 LMS GT3 sports car Audi introduced a pioneering safety concept for this category in 2011. "We've continuously improved in this area and will do so in the future as well," stresses Dr. Wolfgang Ullrich. "The new DTM vehicles are the best piece of proof that you can make something that is already very safe even saver. This is another thing we mean by 'Vorsprung durch Technik.'".


The V8 engine with a power output of about 460 hp (340 kW) will be adopted from the successful A4 DTM nearly unchanged. The proven six-speed transmission will continue to be used as well. Characteristic features of the 2012-generation of DTM vehicles are a larger rear wing and a reduction of the permitted aerodynamics components. The concept studies of the Audi A5 DTM by the Audi Design Team merely suggest the looks of the new Audi race touring car.

Audi A1 quattro





Audi is crowning its successful A1 model series with an exclusive top-of-the-line model. The dynamic A1 quattro, limited to just 333 units, moves to the head of the compact class. Its two-liter, turbocharged engine produces 188 kW (256 hp) and 350 Nm (258.15 lb-ft) of torque, which is delivered to all four wheels. The Audi A1 quattro sprints from zero to 100 km/h (62.14 mph) in 5.7 seconds and has a top speed of 245 km/h (152.24 mph).

                                             The A1 quattro is powered by the 2.0 TFSI engine. The 1,984 cc, four-cylinder engine combines gasoline direct injection with turbocharging in the classic Audi manner. Among its highlights are the adjustable intake cam shaft and the two balance shafts, which ensure smooth operation. Maximum torque of 350 Nm (258.15 lb-ft) is continuously available between 2,500 and 4,500 rpm, and peak power (188 kW/256 hp) is developed at 6,000 rpm.

                                              Every detail of the sporty, sonorous four-cylinder engine has been optimized for high performance and low fuel consumption. Common rail injection, a turbocharger with intercooler and a regulated oil pump are just a few examples. The Audi A1 quattro is expected to consume on average 8.6 liters of fuel per 100 km (27.67 US mpg). Yet it performs like a top-notch sports car: The standard sprint takes just 5.7 seconds, and top speed is 245 km/h (152.24 mph).

                                             The 2.0 TFSI delivers its power to the quattro permanent all-wheel drive system via a precisely shifting six-speed transmission, bringing Vorsprung durch Technik to the small-car class. The heart of this system is an electronically controlled, hydraulically actuated multi-plate clutch whose package of plates rotates in an oil bath.

                                         During normal driving, the clutch sends most of the engine's power to the front wheels. If traction decreases there, the clutch can transfer torque steplessly to the rear axle in just a few milliseconds by forcing the packages of plates together by a defined amount. A pressure reservoir helps the electric pump to develop the oil pressure. If a wheel on one of the axles should slip, it is braked by the electronic differential lock (EDL).

                                          The placement of the multi-plate clutch at the rear axle provides for a harmonious distribution of the axle loads, and the chassis of the Audi A1 quattro has been adapted to the dynamics of the drivetrain. It is much more tautly tuned than that of the production model. The front suspension is a McPherson construction; a four-link axle is used at the rear. The sensitive and efficient electrohydraulic power steering has a sporty, direct 14.8:1 steering ratio.

                                       The Audi A1 quattro rolls on 8.0 J x 18 cast alloy wheels. They are Glacier White, feature an exclusive turbine design and are fitted with 225/35-series tires. The internally vented front brake discs measure 312 millimeters (12.28 in) in diameter and are gripped by black calipers. The ESP stabilization program includes a sport mode and can be switched off entirely for a trip to the race track, for example.

                                   One look is all it takes to see that the Audi A1 quattro is a very special vehicle. It is available only in Glacier White metallic, and its roof is painted high-gloss black. The front bumper is muscular, the frame and grate of the single-frame grille are high-gloss black. The curved bars in the headlights - the wings - are red. The grille, the roof arch and the rear hatch sport quattro badges.

                                        The rear windows are tinted; the roof flows into a large, two-color wing. The color black accentuates the rear hatch and the diffuser. The LED rear lights are tinted; the rear bumper sports a distinctive look. The exhaust system terminates in two polished dual tailpipes on the left and the right, each measuring 100 millimeters (3.94 in) in diameter. The A1 quattro is 3,987 millimeters (13.08 ft) long, 1,740 millimeters (5.71 ft) wide and 1,416 millimeters (4.65 ft) tall, making it somewhat longer than the model on which it is based. Luggage capacity is 210 liters (7.42 cu ft); folding down the rear seats increases this to 860 liters (30.37 cu ft).

                                            Cool, sporty black dominates the interior of the Audi A1 quattro. The seats and the armrests on the doors are covered in Silk Nappa leather with contrasting red seams. The S sport seats up front have pronounced bolsters, integrated head restraints and a quattro badge on the backrest covers. The seats feature multi-way adjustment. The lower section of the center console shines in high-gloss black; the footrest and the pedal caps are made of brushed stainless steel. Red seams frame the floor mats, and the door sill trims bear A1 quattro badges.

                                             The instrument cluster has a number of eye-catching features, including white needles, a red tachometer, the quattro logo and the color display for the driver information system. The multifunction sport steering wheel is flattened at the bottom, wrapped in leather with contrasting red stitching and sports the car's serial number. The shift lever knob is made of aluminum. Many control elements have an aluminum-look finish.

                                             The Audi A1 quattro will be available from the second half of 2012 and will be supplied to customers with a full range of equipment. It includes many features taken directly from the luxury class, including xenon plus headlights, high-beam assistant, adaptive brake lights, LED interior lighting package, light and rain sensor, automatically dimming interior mirror, rear parking system, automatic air conditioning, alarm system, storage package, convenience key and cruise control.

                                          The infotainment equipment likewise leaves nothing to be desired. It includes a CD changer, a digital radio tuner, the Audi music interface and MMI navigation plus. The Bose sound system drives 14 speakers with 465 watts of power; the woofers in the doors are indirectly lit with light guide LEDs. Audi connect uses the Bluetooth online car phone to connect to the Internet and deliver special web services, including Google Earth, to the car. Passengers can also connect their mobile devices to the integrated WLAN hotspot.

Ferrari F12 berlinetta








 Today's on-line unveiling of the F12 berlinetta ushers in a new generation of Ferrari 12-cylinders in the form of a car that delivers unprecedented performance from an exceptional new engine, combined with innovative design that redefines classic themes along with extreme aerodynamics.



Revealed to the world for the first time on Ferrari.com in preparation for its official debut at the Geneva International Motor Show, the F12berlinetta, finished in an attractive new Rosso Berlinetta three-layer colour, represents the very cutting-edge of mid-front-engined sports cars.

This is, in fact, the most powerful and high-performance Ferrari road car ever launched thanks to the incredibly efficient engine - in terms of mechanical, combustion and fluid-dynamics efficiency - which, together with advanced vehicle architecture, aerodynamics, components and electronic controls, guarantee unsurpassed driving involvement whatever the road or track.

Ferrari's traditional transaxle layout has been revolutionised to match the more extreme performance of the car. The wheelbase has been shortened and the engine, dashboard and seats have been lowered in the chassis, while the new layout of the rear suspension and gearbox enabled Ferrari's engineers to make the rear volume of the car smaller. The overall result is a very compact car with a lower centre of gravity that is further back in the chassis, and a level of aerodynamic efficiency that sets new standards.

Scaglietti, renowned for its expertise in aluminium materials and construction, designed an all-new spaceframe chassis and bodyshell using 12 different kinds of alloys, some of which have been used here for the first time in the automotive sector, and employing new assembly and joining techniques. This has resulted in a 20 per cent increase in structural rigidity while reducing weight to just 1525 kg (70 kg less than the previous V12 coupé) with an ideal distribution between the axles (54 per cent over the rear).

The F12berlinetta's 6262cc 65° V12 engine delivers unprecedented performance and revs for a naturally-aspirated 12-cylinder. Its maximum power output is 740 CV which translates to a specific output of 118 CV/l. Torque reaches a peak of 690 Nm, 80 per cent of which is already available at just 2,500 rpm, and which provides an unrelenting surge of acceleration all the way to the 8,700 rpm limit. The engine is mated to the F1 dual-clutch transmission, which has closer gear ratios developed specifically for this car's performance. The F12berlinetta boasts a weight-to-power ratio of just 2.1 kg/CV.
Fuel consumption has been reduced by 30%, with CO2 emissions of just 350 g/km - figures which put the F12berlinetta at the top of the high-performance league. These results have been obtained by extensive research and development which focused on efficiencies of the whole vehicle: engine, aerodynamics, tyres and weights.

Similarly excellent results have been obtained with the car's aerodynamic development, thanks to the integration of the design process with extensive computational fluid dynamics (CFD) simulations and lengthy testing in the wind tunnel. Downforce has been boosted by 76 per cent (123 kg at 200 km/h) while drag has been significantly reduced (the Cd is just 0.299). These results come courtesy of two new solutions. The first of these is the Aero Bridge which uses the bonnet to generate downforce by channelling air away from the upper part of the car to its flanks where it interacts with the wake from the wheel wells to decrease drag. The second is Active Brake Cooling, a system that opens guide vanes to the brake cooling ducts only at high operating temperatures, again reducing drag.

The F12berlinetta's impressive technical specifications are completed by Ferrari's latest generation carbon-ceramic brakes (CCM3) and the evolution of the magnetorheological suspension control system (SCM-E). As is now traditional with all Ferraris, its control systems (E-Diff, ESP Premium, F1-Trac, and high-performance ABS) are all fully integrated.

The result is that the new Prancing Horse 12-cylinder accelerates from 0-100 km/h in 3.1 seconds and from 0 to 200 km/h in 8.5 seconds. It also completes a lap of the Fiorano circuit in 1'23", faster than any other Ferrari road car. Benchmark performance and maximum driving involvement are guaranteed by immediate turn-in, with smaller steering wheel angles, and increased cornering speed. Stopping distances have also been drastically reduced.

The design of the F12berlinetta is a result of the collaboration between the Ferrari Styling Centre and Pininfarina and is a perfect balance of uncompromising aerodynamics with harmonious proportions interpreting the typical elements of Ferrari's front-engined V12 cars in an original and innovative way. A coupé with sleek, aggressive lines whose compact exterior dimensions conceal exceptional in-car space and comfort. The all-new Frau leather interior highlights the balance of advanced technology and sophisticated, handcrafted detailing. In the middle of the light and lean dashboard, there are new carbon fibre and aluminium air vents clearly inspired by the aeronautic field.

The cabin has been optimised to ensure maximum usability of the interior space with additional luggage capacity behind the seats, which can also be easily reached thanks to the large aperture offered by the tail-gate. With the cockpit designed around the driver, typical of all Ferraris, the Human Machine Interface approach is emphasised, grouping all the major commands within immediate reach to guarantee maximum ergonomics for the most involving driving experience.
