The Audi S6 and S7 Are Now Diesels in Europe

Audi switches out the twin-turbo V-8 for a TDI with electric supercharging assistance. Americans will still get a gas engine, however.

Seeing the new Audi A6 and A7 finally revealed last year was cool and all, but deep down, it's the performance models we really care about. Well, the wait is over. Meet the 2020 S6 and S7, newly equipped with V-6 and mild hybrid power.

In Europe, buyers will no longer be able to get a gas-powered S6 or S7. The only engine available is a 3.0-liter twin-turbo V-6 TDI combined with a 48-volt electrical system that powers a supercharger. Making 349 horsepower and 516 lb.-ft. of torque, it can get the S6 sedan from 0 to 62 mph in 5.0 seconds, and the S6 Avant and S7 to the same speed in 5.1 seconds. Top speed for all three models is electronically limited to 155 mph. Six-piston steel brakes on all four corners are standard, while carbon ceramics are optional. Likewise, 20-inch S-specific wheels are base equipment, though they can be substituted for 21s.

For buyers in the United States, Asia, and the Middle East, the powertrain is largely the same, but instead of a 3.0-liter diesel engine, buyers will get a 2.9-liter twin-turbo gasoline V-6 (not unlike the engine found in the current S4 and S5). Equipped with the same standard 48-volt system, it creates 450 horsepower and 442 lb.-ft. of torque. Audi has yet to release performance figures for the S6 and S7 equipped with this engine.

Like in the normal A6 or A7, buyers of these new S models will receive a whole bunch of standard new tech, including a digital instrument cluster, a dual touchscreen dash, and four-wheel steering. There's also that polarizing rear taillight bar that stretches the entire width of the car on the A7.

Sure, that sweet V-8 soundtrack might be gone, but this new powerplant is almost assuredly smoother, more refined, and most importantly of all, quicker.
