2011 Audi A8 compare

The 2011 Audi A8 is an exceptional luxury sedan, with top-of-the-line infotainment and driver assistance features and performance tech that makes it handle like a sports car.

The 2013 Audi S7 features a phenomenal amount of tech both in the cabin and under the hood. An impressive sport driver, its fuel economy remains decent enough for a daily commute.

The 2013 BMW 750Li does double-duty as a freeway cruiser and a getaway car, whether you drive it yourself or hire a chauffeur. A wide array of connected features add new capabilities to the already first-rate navigation and stereo systems.

The conservatively styled 2013 Audi S6 Quattro is a high-tech sport sedan that makes few compromises where cabin technology, on-road performance, and optional safety features are concerned.

The 2014 Acura RLX makes a game attempt at being a high-tech roller, but suffers from flaws serious enough that they should send Acura back to the drawing board.
