2011 BMW 740i compare

The 2011 BMW 740i proves that you don't need a V-8 in an executive sedan. It offers first-rate cabin electronics and driver assistance features, and preserves BMW's sports car reputation.

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 smooth and quiet 2013 Jaguar XJ makes driver comfort its top priority, but an aging cabin technology package and an unrefined fuel-saver system give a rough edge to this refined ride.

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 powerful, comfortable 2013 Mercedes-Benz CLS 63 AMG feels like a car that's worth its high asking price, but we'd wait for the next generation of its Comand interface before taking the plunge.
