Mash the gas from a stop, and the 3.0T delivers linear power that propels the 4114-pound sedan to 60 mph in 5.5 seconds, 1.5 seconds sooner than the old 255-hp, 3.1-liter A6 Quattro hit that mark. Sure, the BMW 535i xDrive and Mercedes E550 4MATIC are quicker, but the BMW requires twin turbos, and the Benz has eight cylinders. More importantly, neither can match the 3.0T’s 18 mpg in the city and 26 on the highway. A big surprise is that this new Audi even outruns the current V-8-powered A6 4.2 Quattro — despite the bigger engine’s 50-hp advantage.
