Previewed in concept form in 2006, the range-topping Q7 is powered by a 6.0-liter twin-turbocharged and intercooled diesel V-12. The race-bred engine makes 500 hp and a glorious 738 lb-ft of torque, propelling the SUV to 62 mph in 5.5 seconds. The variable turbos do their job and make peak torque available from 1750 rpm. We like torque.
You may also remember this engine from its showcase in the back of the R8 V12 TDI concept that was parked at the Detroit show. Audi brought that car to Geneva as well where it wore a coat of red paint. The V-12 was born from a 5.5-liter unit used in the Le Mans-winning R10 prototype.
Power makes its way to the ground via a beefed-up quattro all-wheel-drive system, after going through a specially designed 6-speed tiptronic auto. To help you hold on tight for the ride, Audi supplies wheel-mounted paddle shifters.
