While the 270-hp 3.2-liter FSI V6 remains in the base A6, and the optional 340-hp 4.2-liter FSI V8 is the hot-rod of the group, there’s now a new middle-of-the-road offering. The 3.0T badge may confuse some into thinking this model is turbocharged, but the new engine is really a supercharged 3.0-liter TFSI V6 that puts out 300-hp and 310 ft-lbs of torque.
Strangely, both the V8 and 3.0T do the 0-60 mph run in almost identical times, with the supercharged six posting 5.9 seconds and the V8 a 5.8 second run.
In reality, the new engine is significantly lighter than the old V8 – helping the middle model to weigh in some 200 lbs. less. Not only does that aid acceleration, but fuel mileage as well, with the 3.0T averaging 21 mpg to the V8’s 18. Audi rates the car at 18-mpg city and 26-mpg highway. Otherwise, both share the same six-speed automatic transmission with Tiptronic, and quattro all-wheel drive hardware
