Audi A8

Audi's redesigned top-level sedan features a smooth, powerful turbocharged V6 engine that returned 21 mpg overall in our tests, which is impressive for a large AWD sedan. Audi's new infotainment system looks complex at first, but over time we found it both logical and intuitive to use. We like how the touch screen vibrates to confirm each selection for any audio or climate task. The A8's ride is supremely comfortable, and handling is responsive. The cabin is quiet and impeccably furnished. The front seats are comfortable, supportive, and have a multitude of available adjustments, while the rear seat has limo-like room.

For 2011, Audi brought a significantly improved car. Handling became crisp and grip from the AWD system helped make it one of the sportiest luxury sedans available. Expect a ride that's firm, yet supple. The strong engines deliver smooth and effortless acceleration while attaining commendable fuel economy. Interior ambiance, quality of materials and craftsmanship are top-notch, with exceptionally comfortable and supportive front seats. However, some controls are overly complicated and the trunk is small for a car this size.
