2014 Audi RS7 Sportback

Audi RS7 Sportback, which made its debut at the 2013 North American International Auto Show in Detroit, stands for dynamics at their most beautiful. The large five-door coupe uses a 4.0 TFSI engine producing 412 kW (560 hp). The sprint from zero to 100 km/h (62.14 mph) takes just 3.9 seconds, and the speed governor can be deactivated upon customer request to permit a top speed of up to 305 km/h (189.52 mph). Despite this superior performance, the Audi RS7 Sportback consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg).

Aesthetic design, innovative technology and impressive sportiness: The Audi RS7 Sportback, the large five-door coupe from Audi, combines many strengths to produce a fascinating character. Its strong heart is the 4.0 TFSI, which takes Audi's downsizing strategy to the high-end category. The twin-turbo V8 displaces 3,993 cc and develops awesome power, with 412 kW (560 hp) available between 5,700 and 6,700 rpm. A constant 700 Nm (516.29 lb-ft) of torque are available between 1,750 and 5,500 rpm. Interior of 2014 Audi RS7 Sportback.

Because the high-revving four-liter engine has been rigorously designed for low load-change and flow losses, it develops this power quickly and spontaneously. The cylinder heads have the exhaust side on the inside and the intake side on the outside. The two twin-scroll turbochargers, which produce up to 1.2 bars of relative boost pressure, are located together with the intercooler in the inside V of the cylinder banks. Consequently, the gas paths are very short and response very good. 2014 Audi RS7 Sportback Seats View.

The RS-specific engine management and unthrottled intake system also contribute to the dynamic character of the twin-turbo V8. Switchable flaps in the exhaust system make the engine sound even fuller at the push of a button or under strong acceleration. Audi also offers an optional sport exhaust system. The Audi RS7 Sportback sprints from 0 to 100 km/h (62.14 mph) in just 3.9 seconds. Audi limits the top speed in the standard configuration to 250 km/h (155.34 mph). Top speed with the optional dynamic package is 280 km/h (173.98 mph) and 305 km/h (189.52 mph) with the dynamic package plus. Audi RS7 Sportback (2014)

Yet the new top model of the model series consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg). This top value is due in part to the standard start-stop system and innovative thermal management. The most innovative efficiency technology in the new Audi RS7 Sportback is the cylinder on demand (COD) system. At low to medium loads and engine speeds, it deactivates cylinders 2, 3, 5 and 8 by closing their valves via electromechanical actuators. The 4.0 TFSI then runs as a four-cylinder engine until the driver accelerates more strongly again.

2013 Audi R8

Audi R8 is the sporty spearhead of the Audi model lineup. Now the high-performance sports car is more dynamic than ever, with the S tronic transmission and new features on the exterior, in the cabin and for the brakes. All models now come standard with all-LED headlights. The rear lights mark the premiere of another dynamic innovation: dynamic turn signals. The powerful new Audi R8 V10 plus with 404 kW (550 hp) sprints from zero to 100 km/h (62.14 mph) in 3.5 seconds. Audi R8 2013.

Thanks to Audi ultra lightweight construction, the top-of-the-line model with a manual transmission has a curb weight of just 1,570 kilograms (3,461.26 lb). The reshuffled Audi R8 lineup comprises two body styles - Coupé and Spyder - and three engines. The standard sprint times for both models equipped with the new seven-speed S tronic have improved by 0.3 seconds while fuel consumption has been reduced by as much as 0.9 liters per 100 km (22 grams CO2 per km [35.41 g/mile]).

The eight-cylinder engine powering the Audi R8 V8 delivers 316 kW (430 hp) and 430 Nm (317.15 lb-ft) of torque, the latter between 4,500 and 6,000 rpm. In combination with the seven-speed S tronic, it accelerates the R8 Coupé from zero to 100 km/h (62.14 mph) in 4.3 seconds on its way to a top speed of 300 km/h (186.41 mph). The Audi R8 V10 with the S tronic completes the standard sprint in 3.6 seconds and has a top speed of 314 km/h (195.11 mph).

The ten-cylinder engine produces 386 kW (525 hp) and delivers 530 Nm (390.91 lb-ft) of torque to the crankshaft at 6,500 rpm. Audi is demonstrating its expertise in ultra lightweight construction technology with the updated R8. The Audi R8 V8 with the six-speed manual gearbox (without a driver) tips the scales at just 1,560 kilograms (3,439.21 lb); the R8 V10 plus with the manual transmission weighs 1,570 kilograms (3,461.26). The Audi engineers have reduced the weight of the top model by roughly 50 kilograms (110.23 lb).

The exterior design has been honed ever further. The restructured all-LED headlights and rear lights are standard with all models. The Singleframe grille with tapered corners at the top, the redesigned diffuser and the large, round tailpipes are the most eye-catching new features. The diffuser of the Audi R8 V10 plus features a different geometry and is made of carbon fiber-reinforced polymer. The rear lights of all models include dynamic turn signals, a worldwide first from Audi.
