Elegance on a grand scale – the Audi A7 Sportback
Audi is targeting a new vehicle class with the A7 Sportback. The large, elegant five-door model combines the emotional character of a grand coupe, the comfort and prestige of a sedan and the active practicality of a station wagon. With its lightweight body, the powerful and efficient V6 engines, the sporty chassis and the advanced assistance and multimedia systems, it sets standards in many fields of technology. The Audi A7 Sportback will roll into dealerships in the fall, with prices starting at €51,650.

Engines
The Audi A7 Sportback will hit the market with four direct-injection V6 engines: two gasoline units and two diesels. Ranging from 150 to 220 kW (204 to 300 hp), the engines propel the large five-door coupe smoothly and powerfully, with astonishing efficiency. The 3.0 TDI multitronic with front-wheel drive and 150 kW (204 hp) consumes on average just 5.3 liters of fuel per 100 km (44.38 US mpg), corresponding to CO2 emissions of just 139 g per km (223.70 g/mile). No competitor in this class can boast figures this low. All engines use Audi’s innovative thermal management system, a recuperation system and a start-stop system.

Audi has thoroughly revised the two gasoline engines, the 2.8 FSI and the 3.0 TFSI, with respect to internal friction and thermal management. The engines quickly come up to operating temperature following a cold start. A separate heat exchanger is used to also bring the transmission up to temperature. The 2.8 FSI has an additional efficiency technology on board – the Audi valvelift system varies the stroke of the intake valves as needed. This enables the engine to breathe with significantly reduced throttle losses in many partial-load ranges, boosting torque and reducing fuel consumption.

The 2.8 FSI produces 150 kW (204 hp) and 280 Nm (206.52 lb-ft) of torque at 5,250 rpm. The torque is available from 3,000 to 5,000 rpm. Audi pairs this engine with the S tronic transmission and quattro all-wheel drive. The A7 Sportback 2.8 FSI quattro sprints from zero to 100 km/h (62.14 mph) in 8.3 seconds and has a top speed of 235 km/h (146.02 mph). It consumes just 8.0 liters of fuel per 100 km (29.40 US mpg) on average, which corresponds to only 187 grams of CO2/km (300.95 g/mile).

With the top gasoline engine, the 3.0 TFSI, a supercharger compresses the intake air for improved efficiency and performance. The three-liter V6 produces 220 kW (300 hp) between 5,250 and 6,500 rpm, and delivers 440 Nm (324.53 lb-ft) of torque between 2,900 and 4,500 rpm. The supercharged engine, which in Europe is mated to the S tronic and the quattro powertrain, gives the five-door coupe the performance of a sports car.

The standard sprint takes just 5.6 seconds, and top speed is limited to 250 km/h (155.34 mph). Standard fuel consumption is just 8.2 liters per 100 km (28.68 US mpg), corresponding to 190 grams CO2 per km (305.78 g/mile).
The 3.0 TDI is available in two versions. The more powerful version of the big diesel, which has been completely redesigned, produces 180 kW (245 hp) between 4,000 and 4,500 rpm and 500 Nm (368.78 lb-ft) of torque between 1,400 and 3,250 rpm. The S tronic and quattro all-wheel drive are also standard here. Acceleration from 0 to 100 km/h (62.14 mph) takes 6.5 seconds and top speed is limited to 250 km/h (155.34 mph). Efficiency is impressive: just 6.0 liters of fuel per 100 km (39.20 US mpg) on average, which corresponds to only 158 grams of CO2/km (254.28 g/mile).

The second version of the 3.0 TDI, which will follow somewhat later, does even better in this discipline. It produces 150 kW (204 hp) between 3,750 and 4,500 rpm. With front-wheel drive and the stepless multitronic automatic transmission, it really flaunts its efficiency: 139 grams CO2 per km (223.70 g/mile) and an average fuel consumption of 5.3 liters per 100 km (44.38 US mpg) are groundbreaking figures. With the new Efficiency TDI, the front-wheel drive A7 Sportback accelerates from 0 to 100 km/h (62.14 mph) in 8.1 seconds and reaches a top speed of 234 km/h (145.40 mph).

With the 3.0 TDI with 150 kW (204 hp), the timing of the cam shafts, the turbocharger and the common rail system with an injection pressure of 2,000 bar have been designed specifically for low fuel consumption. With front-wheel drive, the V6 diesel produces 400 Nm (295.02 lb-ft) of torque. The power is continuously available between 1,250 and 3,500 rpm. With quattro all-wheel drive, it is 450 Nm (331.90 lb-ft) of torque that is available between 1,250 and 3,500 rpm.
