It’s been fascinating to sample Audi’s new greener edition of the EA824 V8 in all of its various incarnations. Our first crack at the new TFSI powerplant with cylinder-on-demand was in Audi’s own 513-horsepower S8, and we then went on to try it out in the new 500-hp Bentley Continental GT and GTC V8 models. Most recently, we dipped into the 4.0-liter biturbo in the new S7 before getting behind the wheel of the closely related S6 seen here.
Versus the previous S6 with its muy macho Lamborghini-derived 5.2-liter V10, everything is quicker, more efficient and lighter in weight. The new fourth-generation S6 Quattro with S-tronic seven-speed dual clutch comes in at a European curb weight of 4,178 pounds – about 30 pounds lighter than the previous V10-stuffed car with its automated six-speed. Yes, power is slightly lower now at 414 horses, but peak torque of 406 pound-feet is slightly higher and happens over a vastly wider range of 1,400 to 5,200 rpm. Audi’s 0-62 miles per hour sprint time is now listed at 4.6 seconds, a figure that compares favorably with the outgoing car’s official 5.2-second time.
For my test drive, Audi thoughtfully provided a couple of S6 four-door setups for me to sample: those with Dynamic Steering and the torque vectoring sport Quattro rear differential, and those without. You know which trim I went for already. So equipped, these S6 sedans were all painted Misano Red… an exterior color that Americans cannot get this time around.
