The Audi S lineup is not a world filled with many choices. Sure, you can pick your poison in terms of which S vehicle you want, but you do not have a say in which engine is mounted under the hood. However, it seems the upcoming Audi S6 and S7 might be poised to break with that tradition.
Rumor has it that the more athletic versions of the A6 and A7 will be offered with a choice of engines. The standard engine for both cars is slated to be a turbocharged 4.0-liter V8 with around 450 horsepower, but Audi is reportedly going to offer up a diesel, as well, marking the first time such an engine has been offered with an S-branded vehicle. This 3.0-liter turbodiesel V6 should be good for 300 horsepower and 450 pound-feet of torque.
