2013 BMW M5 compare

With its power and high-tech handling, the 2013 BMW M5's potential feels wasted on public roads, yet its driver-assistance and cabin-tech systems are the best in the business for road trips and daily commutes.

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 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.

As optioned, this example of a 2012 BMW 335i makes for an acceptable commuter car with some very advanced cabin tech features and good fuel economy, but a few different choices could turn it back into an ultimate driving machine.
