Drive system
For the start of sales in Europe, Audi is equipping the new A7 Sportback with powerful six-cylinder engines: a 3.0 TFSI and a 3.0 TDI. The turbocharged gasoline engine in the A7 Sportback 55 TFSI quattro (Combined fuel consumption in l/100 km: 7.2 – 6.8 (32.7 – 34.6 US mpg); Combined CO2 emissions in g/km: 163 – 154 (262.3 – 247.8 g/mi) produces 250 kW (340 hp) and delivers 500 Nm (368.8 lb-ft) of torque over a broad band from 1,370 to 4,500 rpm. It accelerates the big coupé from 0 to 100 km/h (62.1 mph) in 5.3 seconds; top speed is 250 km/h (155.3 mph). In the NEDC, the Audi A7 Sportback 55 TFSI consumes just 6.8 liters of fuel per 100 kilometers (34.6 US mpg), corresponding to 154 grams CO2 per kilometer (247.8 g/mi).
The new three-liter V6 is packed with innovations. Its exhaust end lies inside the 90° vee, the short gas paths and the twin scroll charger, which prevents unwanted interactions between the gas columns, guarantee spontaneous throttle response. The B-cycle combustion process, which is designed specifically for part load, makes the V6 gasoline engine particularly efficient. To support it, the Audi valvelift system (AVS) adjusts the intake valve opening times and stroke in two stages based on load and engine speed. The three-liter gasoline unit produces a subtle and sonorous sound that never becomes intrusive even under load. This is due in part to the new tube guide in the dual-branch exhaust system that largely eliminates hum frequencies.

The V6 TFSI has shed 14 kilograms (30.9 lb) and now weighs 172 kilograms (379.2 lb). Its aluminum crankcase features integrated, thin-walled cylinder liners of gray cast iron. In combination with the newly developed rings for the aluminum pistons, this reduces friction. Another efficiency element is thermal management with separate cooling loops for the crankcase and cylinder head. The exhaust manifold is integrated in the cylinder head and bathed in coolant. This helps the engine to heat up quickly following a cold start. When the engine is warm, this solution lowers the exhaust temperature, reducing fuel consumption, particularly during sporty driving.

Audi is also offering the A7 Sportback 50 TDI quattro tiptronic (Combined fuel consumption in l/100 km: 5.8 – 5.5 (40.6 – 42.8 US mpg); Combined CO2 emissions in g/km: 150 – 142 (241.4 – 228.5 g/mi) as a second engine variant at market introduction. It produces 210 kW (286 hp) and delivers 620 Nm (457.3 lb-ft) of torque between 2,250 and 3,000 rpm. In the NEDC it consumes just 5.5 liters of fuel over 100 kilometers (42.8 US mpg), analogous to 142 grams CO2 per kilometer (228.5 g/mi). The accelerates the Gran Turismo from zero to 100 km/h (62.1 mph) in 5.7 seconds on its way to a top speed of 250 km/h (155.3 mph).
Weighing just 190 kilograms (418.9 lb), the 3.0 TDI combines numerous high-tech features. These include particularly complex thermal management, newly developed cylinder heads, greatly reduced friction, a modified chain drive and an electrically adjustable turbocharger that develops up to 2.0 bar of boost pressure. The diesel engine also works together with a 48-volt MHEV electrical system.
Additional four and six-cylinder engines will gradually round out the engine lineup in the course of 2018.
For power transmission, the Audi A7 Sportback 55 TFSI is equipped with a seven-speed S tronic, which has been redesigned in many details in view of the high torque. The double-clutch transmission changes gears quickly and almost imperceptibly; thanks to its electrically driven oil pumps and pressure accumulator, it can do so during coasting with the engine stopped.
The 3.0 TDI is mated to an eight-speed tiptronic. An rpm-adaptive torsion damper with a centrifugal force pendulum largely compensates for undesirable vibrations in the engine. This permits efficient driving from engine speeds as low as 1,000 rpm. When coasting and rolling out, a clutch in the central transmission opens and interrupts the power connection. A new electric oil pump makes it possible to engage the gear that will be needed after the rolling phase. The transmission control unit detects stop-and-go situations and ensures very comfortable starts.
The S tronic transfers the engine power to a quattro drive with ultra technology. The drivetrain is highly efficient – it always activates the rear wheel drive when needed. There are no differences in terms of traction and handling compared to permanent systems.
