Audi Q7 2011
Saturday, June 11, 20112011 Audi S3
Monday, May 23, 201123The Audi S3 is produced by the German manufacturer, Audi. The Audi S3 is a hot hatch, or high performance version, of the Audi A3 hatchback. Although they are similar in appearance, the Audi S3 offers a lot more than the A3. Audi S3 versions of first and second generation A3 models have been manufactured. The Audi S3 has been manufactured since 1999, with the second generation having been produced since 2006.
The second generation of the Audi S3 offers better performance than the first generation. A number of updates were made to the S3, so that the newer version with its more powerful engine and four wheel drive can reach speeds of 62 miles per hour or 100 kilometers per hour in 5.5 seconds.
The S3 is not sold in North America, because Audi believe it would be in direct competition with the Golf R32 from Volkswagen and that it would also affect sales of Audi's own TT model.
The Audi S3 is designed for action. It performs well without any fuss, making it a good choice for drivers who demand a lot from their vehicles. Upgrading from the A3 to the S3 makes sense if you are going to drive your car hard and make use of this additional power and performance. The manual transmission version of the S3 allows the driver to shift through the gears quickly, and much more smoothly than in an A3.
The S3 performs particularly well for long distance driving, so it will be a good choice for people who regularly need to travel long distances by road. Driving the S3 is a comfortable experience. It makes driving long distances feel easy. The combination of excellent performance and ease of driving provided the Audi S3 could prove dangerous for careless drivers, however, since it does make it easy to drive too fast. Unless this car is driven by a responsible person, it could be easy to exceed the speed limit.
The S3 may have either a 6 speed manual or an S-Tronic transmission. The S3, as with all models in the Audi S line, comes with quattro four wheel drive. The Audi S3 features a switch that can be used to alter the suspension. The Sport setting will not be of much use to most drivers, however, since the ride will be more comfortable on the normal setting.
The S3 provides a similar amount of internal space for passengers and luggage as the Volkswagen Golf. It will fit five adults while leaving an acceptable amount of luggage space. The rear seats can be dropped in order to provide more storage space, if necessary. The S3 is available either as a three or five door car.
The Audi S3 is generally considered to be a relatively expensive vehicle. The S3 is not just a more powerful vehicle than the A3 upon which it is based, but a more expensive one too. As well as costing more than the Audi A3, the S3 is more expensive than many similar vehicles from other manufacturers. For the price of an S3, it would therefore be possible to choose a powerful saloon car such as the 330i SE from a prestigious manufacturer, BMW. Another option would be to save some money while getting a car with similar features to the S3, such as the Scirocco coupe from Volkswagen or even to stick with the A3 from Audi. Paying for the extra performance of the S3 may not be sensible for all buyers, since they will not need the additional power. However, drivers who need more performance will find that the S3 is more suited to their needs than the cheaper A3.
The S3 does offer a number of advantages over similar models from different manufacturers, which may make it a better choice for some drivers. Neither the Sciorocco nor the 3301 SE provide four wheel drive, for example. This could be an important feature for drivers who live in a hilly, remote area, although it is not a feature that would be missed by the many drivers who rarely leave the city. The four wheel drive feature does make it possible to accelerate more quickly from a stationary start, however, which may be an advantage for some drivers and m ay make driving the S3 a more pleasurable experience for high performance drivers.
Although the competition in the same price range is very tempting, the S3 will be the best choice for drivers who want a practical, uncomplicated car that will be easy to drive, but who need more than the Audi A3 is able to provide.

The Abt R8: Sports car in perfection
There are cars and dream cars. The latter includes Lamborghini's Gallardo, Ferrari's F430 or Porsche's 911 Turbo. These cars make your heart beat faster and show the perfected magic of speed on the roads. Abt Sportsline's R8 will also be among these outstanding super sports cars and is getting ready to overtake them in the prestige duel.
The design studies already show the first impressions of Abt's sportiest creation - and prove that the Kempten-based tuner manages to perfect an excellent serial model like the R8 to detail and accentuate its racing genes already in the drawing. The front of the Bavarian R8 shows the marked Abt face. Together with the unique and beautiful rear with its four inclined arranged exhaust end pipes, the rear diffuser and the extravagant rear wing, the front of the Abt R8 is part of an overall concept that brings about phenomenal roadholding. The add-on parts of the super sports cars from the Allgäu-region improve downforce and ensure perfect balance of the front and rear axis. This is especially notable in speed ranges reserved for only a few cars. The sideblades which were developed especially for the Abt R8 and the Abt side skirts give the Abt R8 a new and individual design besides aerodynamical advantages. The aerodynamically efficient Abt body kit, which also includes carbon-fibre parts, is a real eye catcher but also shows the state-of-the-art Bavarian precision work. With the ingenious construction, which also includes a carbon-fibre bonnet, not only a maximum reduction in weight is achieved but it also ensures optimized weight distribution of the Abt R8 - the pure presence of the model athlete already shows this.
The technology and the design milestones do not only come from Maranello or Sant'Agata-Bolognese but also from Kempten. The Abt R8 will be a gorgeous dream car with the genes of a top-class race car. This special automobile will belong to one of the fastest among the fastest; the Abt R8 will also challenge the Lamborghinis and Porsches. With regards to the anticipated performance data the Bavarians are traditionally discreet. But this data already amazes sports car fans and makes them want to spur the hot-blooded Bavarian horses. 530 HP (390 kW) are to be drawn from the 4.2 litre-V8 thanks to the Abt supercharger. Compared with the serial model which already shows impressive performance data this means an increase of 110 HP (81 kW). The brand new Abt 20-inch BR wheels stylishly transfer this power onto the asphalt. The all-wheel-drive dream car accelerates from 0 to 100 km/h in just 3.9 seconds and reaches a top speed of 317 km/h. These values are synonymous with magic and this extraordinary super sports car desperately wants to be driven. By means of the Abt suspension which is adjustable in height, pressure and rebound, the performance and driving comfort of the super sports car can be adapted perfectly to the requirements of its driver.
Audi Q7, 2006
Audi Q7, 2006
The Q7 is the large Audi for sporty individualists, for people who are seeking a vehicle that will take them anywhere they want to go for sports, recreation, and business. Its dynamic proportions and distinctive lines express this character, and subtle modifications endow its styling with even more elegance.
The design: The language of dynamics
At the front end, the large single-frame radiator grille has been redesigned. Vertical chrome bars contrast with its black high-gloss finish. The bumpers too have been restyled. Their lower section is now painted in a contrasting black or gray, depending on the body color. The newly integrated underbody protection in the center section of the bumper has a distinctive ribbed design.
The interior: Room to spare
Thanks to its luxurious 300-centimeter (118.11-inch) wheelbase within an overall length of 5.09 meters (16.70 feet), the Audi Q7 has interior room to spare, and the interior flexibility is unrivalled. The seatbacks in the second row are divided into three fold-down sections to provide a level cargo floor.
This increases the luggage space from a volume of 775 liters (27.37 cubic feet) to 2,035 liters (71.87 cubic feet). With the leather upholstery option, the middle seat now has an even more comfortable contour.
Two very useful features are optionally available: either a longitudinally displaceable second seat row or individual comfort seats that are separately displaceable. Another available option is a third row for passengers no taller than 1.60 meters (5.25 feet), combined with an improved easy entry function.
A multitude of detailed improvements in the interior enhance the elegance and the sense of well-being. The instrument cluster has been redesigned: the large, round, easily readable instruments are encircled by metallic frames. Interior lights in the door linings and an inlay on the passenger side enhance the interior styling. Many details of the control elements have been restyled and also enhanced by chrome elements.
The selection of interior colors and materials is also new. Upholstery fabrics are available in black and light gray; leather upholstery additionally also in Para Brown, Savannah Beige and Cardamon Beige. Standard inlays are finished in matt black. In optional design packages, aluminum and wood finishes are used.
The power train: Performance and efficiency
The Audi Q7 is available with six powerful and highly efficient direct injection engines, two of them gasoline-powered and four diesel engines, including the world's most powerful diesel SUV, the Audi Q7 V12 TDI. Their power is transmitted via a convenient and fast-shifting six-speed tiptronic to the quattro permanent all-wheel drive, which distributes it between the axles with slightly more than half to the rear.
The 3.0 TDI puts out 176 kW (240 bhp) and delivers as much as 550 Nm between 2,000 and 2,250 rpm, yet on the EU cycle it consumes only 9.1 liters / 100 km (25.85 US mpg). The optionally available 3.0 TDI clean diesel even consumes 0.2 liters (0.05 US gallons) less.
Despite highly complex exhaust gas recirculation and the resulting world's cleanest diesel technology, it consumes just 8.9 liters/100 km (26.43 US mpg). It meets the strict LEV II Bin 5 US standard and already complies with the Euro 6 limits announced for 2014.
The technology of the TDI clean diesel is highly complex. An advanced version of the common rail injection system with 2,000 bars of pressure, new combustion chamber sensors and a high-performance exhaust recirculating system ensure a highly efficient combustion process. An innovative DeNOx catalytic converter reduces the remaining nitrogen oxides. Just upstream of it, a pump injects an additive named AdBlue into the hot exhaust flow, where this solution decomposes into ammonia, which splits the nitrogen oxides into harmless nitrogen and water. Audi partners replenish the additive during regular maintenance servicing.

ABT Audi TT-R, 2007
The Abt TT-R
The real racer from the exclusive Kempten-based tuning company bears the letter "R" in its name - of course the powerful version of the TT performing incredible 355 HP (262 kW) does, too. In a flash, namely 5.1 seconds, the sportscar reaches the 100 km/h threshold.
The cockpit of the TT-R has a lot to offer its ambitious driver.
With its dynamical design it harmonizes perfectly with the sporty vehicle character - steering wheel, gear shift knob and centre console are kept in exclusive carbon-leather optics.
The magical three letters that convert a beautiful Coupé into a race car can also be found in the car interior again, as everybody driving a TT-R cannot get enough of this exclusive model.

Audi A4 allroad quattro, 2010
Audi A4 allroad quattro, 2010
With its permanent all-wheel drive and increased ground clearance, the Audi A4 can handle any road or trail; it also offers driving pleasure - even on unpaved surfaces. Naturally, the Audi A4 allroad quattro features all the innovative technologies which impart to the A4 model line its superiority: a range of powerful and highly energy-efficient engines, Audi drive select (intelligent handling technology), the high-tech S tronic transmission, and innovative communication and assistance systems. The vehicle will be available in early summer at a basic price of 37,100 euros.
The design of the Audi A4 allroad quattro recalls the Audi A4 Avant: crisp lines enclose tastefully curved surfaces and the low roof line establishes a coupé-like silhouette. Striking details re-interpret this model line's sporty elegance. The moon-gray single-frame radiator grille bears vertical chrome strips; an accentuated bumper and large air inlets underscore this vehicle's unique identity. Chrome rings encircle the fog lights. And in the option featuring xenon plus headlights, light-emitting diodes comprise the daytime running lights and taillights. Underneath the front end and tail end, the A4 allroad has a stainless-steel underbody guard.
Interior
Refined touches, uncompromising quality and flawless functionality: the interior of the Audi A4 allroad quattro embodies all the strengths for which Audi is renowned. The cockpit clearly serves the driver. Among the control unit's highlights: the standard electromechanical handbrake - which has replaced the lever on the center console with a button - and the central on-board monitor. A color display complements the concert or symphony sound system, or the MMI navigation system plus; the MMI's offset control unit is housed in the center console.

A color display complements the concert or symphony sound system, or the MMI navigation system plus; the MMI's offset control unit is housed in the center console.
The Engines
Audi will initially offer three different engines for the Audi A4 allroad quattro: a gasoline engine and two diesel engines. All three are turbocharged direct-fuel-injection engines. They command respect due to excellent performance, impressive pulling power, smooth running, and high fuel efficiency. The engines are further bolstered by pioneering technologies arising from Audi's modular efficiency expertise. For example, all three units boast a standard on-board recuperation system, which converts mechanical energy into electrical energy during deceleration.
The Driveline
The 2.0 TDI transmits its power to a six-speed manual transmission. The 3.0 TDI and 2.0 TFSI feature the next generation of Audi's dynamic and very efficient S tronic. This innovative dual-clutch transmission switches extremely smoothly among its seven gears within a few hundredths of a second. S tronic also excels thanks to its high efficiency ratio and a broad spread of the gear ratios. The seven-speed S tronic has a fully automatic mode at the ready: the driver can shift as required, if necessary via shift paddles on the steering wheel.
The differential is in front of the clutch and immediately behind the engine. This technical stroke of genius made it possible to reposition the front axle much closer to the vehicle's front end, in turn allowing for a long wheelbase and an ideal distribution of the axle loads. The benefits include steady straight-line stability, superb ride comfort, and excellent driving dynamics.
The Audi A4 allroad quattro features quattro permanent all-wheel drive as standard equipment. Its purely mechanical center differential favors the rear, distributing power at a 40:60 ratio to the front and rear axle. If necessary, the quattro permanent all-wheel drive can route up to 65 percent to the front or as much as 85 percent toward the tail end.
The Chassis
The width of the Audi A4 allroad quattro lays the foundation for its driving dynamics. The car's track is 1,583 mm (62.32 in.) at the front and 1,574 mm (61.97 in.) at the rear - some 20 mm (0.79 in.) wider, respectively, than the A4 Avant. The body is higher on account of a new chassis with longer springs, which - like the new shock absorbers - combine sportiness with comfort. The standard, 17-inch lightweight alloy wheels are fitted with 225/55 tires. At a diameter of 690 millimeters (27.17 inches), even this standard configuration looks rather imposing. For the time being, Audi is also offering 18-inch wheels.
The chassis in the Audi A4 allroad quattro retains all the advantages which distinguish the A4 model line. Steering is straightforward and responsive. A steering box beneath the wheel conveys the driver's input directly to the wheels. The five-link front suspension and the self-tracking trapezoidal-link rear suspension consist largely of aluminum to reduce unsprung weight. 16-inch brakes with excellent cooling behavior provide for rapid deceleration. It should come as no surprise that the Audi A4 allroad quattro offers sportiness, comfort, and stability - onroad and offroad. After all, it is an A4.
On rough terrain, the Audi A4 allroad quattro relies on a high-tech feature of its Electronic Stabilization Program (ESP): the Offroad Detection (ORD) technology automatically identifies the type of driving surface and adjusts the ESP's control parameters accordingly. When the driver depresses the gas pedal, ESP increases propulsive power by tolerating more wheel spin than otherwise. If necessary, it will override for a time in the interests of safety.
On paved roads, Audi drive select further enhances the joys of driving. This control system automatically and perfectly adapts the personality of the Audi A4 allroad quattro to the driver's preferences. Audi drive select namely evaluates the engine's throttle response, the Servotronic power steering, and S tronic's shift points in automatic mode. The driver can freely switch among three different engine maps: comfortable, standard, and sporty. And MMI navigation plus provides yet another on-board control option, and is individually programmable.
The Audi drive select can be paired with Audi dynamic steering. It consists of a superimposed gear system, and varies the steering ratio as well as steering assistance in a continuously variable manner. Audi drive select functions directly at low speeds and indirectly at high speeds. At the vehicle's cornering limit, the dynamic steering keeps the Audi A4 allroad quattro on course via split-second corrective actions - subsequently obviating extensive ESP intervention.
Audi A1 e-tron Concept, 2010
Audi A1 e-tron Concept, 2010
The new e-tron model series from Audi will gain another new member at the 2010 Geneva Motor Show: The Audi A1 e-tron Concept is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city. There is also an internal combustion engine on board that recharges the battery in exceptional circumstances. The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor.
The technology of the Audi A1 e-tron
The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt/Main, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.
The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.
The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.
Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.
The electric motor: 75 kW (102 hp) peak power
The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).
The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.
The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.
The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.
This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.
The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.
The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.
The battery pack: a compact T arranged below the floor
The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).
The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.
The range extender
The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).
The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.
Driving experience
The first defining impression that the driver of the Audi A1 e-tron gets is that of nearly total silence. Even the Wankel engine in the back can barely be heard when it is running.
The second characteristic perception is the power of the electric motor, nearly all of which is available instantly and thrusts the Audi A1 e-tron forward with authority. The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms (2,623.50 lb) delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph).
The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles).
According to the draft standard, the two different operating modes yield a fuel consumption of only 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile). In electric mode, there are zero local CO2 emissions - the compact Audi A1 e-tron Concept is thus ecological and economical.
The third impression that the Audi A1 e-tron Concept makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series - the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tires; the generous, "grown-up" interior; the excellent fit and finish; and a multitude of high-end equipment.
Design
The concept car in Geneva has a special "Aqua Mint, pearl effect" paint finish; the contrasting roof arch is offset in "High Gloss Steel dark." As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept.

The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.
Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.
The electric motor: 75 kW (102 hp) peak power
The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).
The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.
The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.
The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.
This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.
The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.
The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.
The battery pack: a compact T arranged below the floor
The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).
The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.
The range extender
The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).
The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.
Driving experience
The first defining impression that the driver of the Audi A1 e-tron gets is that of nearly total silence. Even the Wankel engine in the back can barely be heard when it is running.
The second characteristic perception is the power of the electric motor, nearly all of which is available instantly and thrusts the Audi A1 e-tron forward with authority. The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms (2,623.50 lb) delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph).
The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles).
According to the draft standard, the two different operating modes yield a fuel consumption of only 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile). In electric mode, there are zero local CO2 emissions - the compact Audi A1 e-tron Concept is thus ecological and economical.
The third impression that the Audi A1 e-tron Concept makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series - the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tires; the generous, "grown-up" interior; the excellent fit and finish; and a multitude of high-end equipment.
Design
The concept car in Geneva has a special "Aqua Mint, pearl effect" paint finish; the contrasting roof arch is offset in "High Gloss Steel dark." As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept.

The Abt R8: Sports car in perfection
There are cars and dream cars. The latter includes Lamborghini's Gallardo, Ferrari's F430 or Porsche's 911 Turbo. These cars make your heart beat faster and show the perfected magic of speed on the roads. Abt Sportsline's R8 will also be among these outstanding super sports cars and is getting ready to overtake them in the prestige duel.
The design studies already show the first impressions of Abt's sportiest creation - and prove that the Kempten-based tuner manages to perfect an excellent serial model like the R8 to detail and accentuate its racing genes already in the drawing. The front of the Bavarian R8 shows the marked Abt face. Together with the unique and beautiful rear with its four inclined arranged exhaust end pipes, the rear diffuser and the extravagant rear wing, the front of the Abt R8 is part of an overall concept that brings about phenomenal roadholding. The add-on parts of the super sports cars from the Allgäu-region improve downforce and ensure perfect balance of the front and rear axis. This is especially notable in speed ranges reserved for only a few cars. The sideblades which were developed especially for the Abt R8 and the Abt side skirts give the Abt R8 a new and individual design besides aerodynamical advantages. The aerodynamically efficient Abt body kit, which also includes carbon-fibre parts, is a real eye catcher but also shows the state-of-the-art Bavarian precision work. With the ingenious construction, which also includes a carbon-fibre bonnet, not only a maximum reduction in weight is achieved but it also ensures optimized weight distribution of the Abt R8 - the pure presence of the model athlete already shows this.
The technology and the design milestones do not only come from Maranello or Sant'Agata-Bolognese but also from Kempten. The Abt R8 will be a gorgeous dream car with the genes of a top-class race car. This special automobile will belong to one of the fastest among the fastest; the Abt R8 will also challenge the Lamborghinis and Porsches. With regards to the anticipated performance data the Bavarians are traditionally discreet. But this data already amazes sports car fans and makes them want to spur the hot-blooded Bavarian horses. 530 HP (390 kW) are to be drawn from the 4.2 litre-V8 thanks to the Abt supercharger. Compared with the serial model which already shows impressive performance data this means an increase of 110 HP (81 kW). The brand new Abt 20-inch BR wheels stylishly transfer this power onto the asphalt. The all-wheel-drive dream car accelerates from 0 to 100 km/h in just 3.9 seconds and reaches a top speed of 317 km/h. These values are synonymous with magic and this extraordinary super sports car desperately wants to be driven. By means of the Abt suspension which is adjustable in height, pressure and rebound, the performance and driving comfort of the super sports car can be adapted perfectly to the requirements of its driver.
