| Review Summary |
The big 2008 Audi A8 L W12 combines high luxury and surprisingly sporty performance. Its tech credentials are anchored by a stellar Bang & Olufsen audio system, and include some innovative driving tech. While quite nice to drive, a chauffeur makes a fine accessory. |
The 2009 Audi S8 is a very powerful big sedan with some excellent handling features, but it doesn't offer all of the latest in-dash gizmos, and you trade a luxury ride for performance. |
The 2009 BMW 750Li delivers impressive tech features on all fronts, helping justify its high price. It offers the best cabin tech package among its competitors. |
The 2008 Mercedes-Benz S63 AMG defines luxury and performance, offering usable and high-quality cabin gadgets pushed down the road by a powerful, and thirsty, engine. |
If you can pay for the gas, the 2009 Mercedes-Benz S550 has many features to recommend it, and offers an incredibly comfortable ride, but don't expect it to play well with your personal electronics. |
