2012 Bentley Mulsanne compare

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 Lexus LS 460 F-Sport's performance upgrades don't transform it into a sports car, but add a sporty edge to the luxury sedan's already good cabin and comfort tech offerings.

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.
