Seven years young, yet still no wrinkles for the sensuous A5 coupe! All A5s, including the convertibles, are delivered with the quattro all-wheel drive hardware. Base models use Audi’s 220-hp 2.0L turbo four, paired to a six-speed manual or eight-speed automatic, while the S5 shares the S4’s 333-hp supercharged 3.0L V6, six-speed manual and seven-speed auto box. Need more power? The RS 5’s 4.2L V8 churns out 450 horsepower at 8250 rpm, while torque is set at 317 lbs.-ft.
