Standard Sedan

The Bottom Line: The 2010 Mercedes-Benz E550 Coupe strikes a balance between luxury and sport, with engaging driving and high quality cabin electronics, while presenting a very stylish exterior.

The Bottom Line: 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 Bottom Line: Although none of its cabin tech is over the top, the 2009 Acura TSX offers a complete roster of useful in-dash gadgets. Its enjoyable driving characteristics make it a great driver in a variety of situations, from commute traffic to road trips.

The Bottom Line: Although not in any way a sport sedan, the beefy-looking 2008 Ford Taurus will get you around in comfort, and the navigation system makes it easy to set up complex routes.

The Bottom Line: You won't notice the 2007 Acura RL's shortcomings if you don't push it hard, and its cabin gadgets are very easy to use. If it weren't for the mediocre fuel economy, the RL would be a very good high-tech commute car.

The Bottom Line: The 2007 Jaguar Super V8 looks good and features a luxurious interior, whether you sit in the front or back. But its tech offerings are a mixed bag, with a dated stereo but modern cell phone integration.

The Bottom Line: The 2006 Cadillac STS-V is built like a tank, goes like a train, and drinks like a fish. A comfortable, tech-laden cabin and blistering top-end performance make this car a serious contender on the sports sedan stage.
