Late to the “four-door coupe” party started by Mercedes’ CLS in 2005, the A7 has arguably ended up the most attractive in a class that also includes the awkward-looking BMW 5 Gran Turismo. As with the A6, the A7 gets a 310-hp, supercharged 3.0L V6 matched to an eight-speed automatic, connected to a Quattro all-wheel-drive system. New for 2013 is the sportier S7. Just as in the S6 sedan, the S7’s new 420-hp twin-turbo V8 features fuel-saving stop-start functionality and cylinder-deactivation that shuts down four cylinders under lighter loads and shares the seven-speed dual-clutch auto and Quattro all-wheel-drive powertrain with other Audi S models.
