Cultivated power - the V6 engines 2011 Audi A7

Audi offers the A7 with a choice of four powerful and cultivated V6 engines: two gasoline and two diesel units. They produce between 150 kW (204 hp) and 220 kW (300 hp), and their efficiency sets new standards in the vehicle class. The new 3.0 TDI, which will be available somewhat later, produces 150 kW (204 hp) and with the multitronic transmission consumes on average just 5.3 liters of fuel per 100 km (44.38 ÚS mpg), corresponding to groundbreaking CO2 emissions of just 139 g/km (223.70 g/mile). All engines feature a recuperation system, thermal management and a start-stop system.

The standard automatic transmissions also play a role in the high efficiency of the Audi A7. Audi offers two different transmissions depending on the engines: The convenient multitronic sends engine power to the front wheels, the sporty seven-speed S tronic to all four wheels. The quattro permanent all-wheel drive system is state of the art. Featuring a crown-gear center differential and torque vectoring, it is particularly flexible and dynamic. The optional sport differential actively distributes the power between the rear wheels.

The chassis, too, combines sporty precision with luxurious comfort. The Audi A7 rolls on large wheels measuring from 18 to 20 inches in diameter. Its links are made of aluminum; the newly developed power §teering features a highly efficient electromechanical drive. The Audi drive select dynamics system is standard and can be supplemented by the optional adaptive air suspension with controlled damping. The dynamic §teering system, which varies its §teering ratio according to the speed being driven, will follow somewhat later.
