The 2.0-liter turbocharged 4-cylinder that's standard in the Audi A5 is as good as it gets for a "base" engine, especially with 220 smooth horsepower, standard front-wheel drive (FWD) or quattro AWD, and your choice of a 6-speed automatic or an 8-speed automatic with Tiptronic manual control. However, we're particularly fond of the 3.0-liter supercharged V6 in the Audi S5, with its 333 horsepower and 325 lb-ft of torque. If that's not enough, and you don't mind a fuel-economy penalty, the RS 5's 4.2-liter normally aspirated V8 puts out 450 horsepower. Maybe it's a little old-school, but really, who cares?
