Standard Sedan

The Bottom Line: The 2009 Lexus GS 450h offers power and luxury, without costing a bundle at the pump. But merely average cabin tech suggests waiting for a model update.

Specs: Sedan, Hybrid

The Bottom Line: 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 Bottom Line: The 2009 Acura TL SH-AWD tries to strike a balance between comfortable commuter car and weekend sport driver, but leans towards the former. Cutting edge cabin tech increases the comfort level and gives it a practical edge.

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: 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 Acura TL Type-S has all the ingredients to combine techno luxury with performance driving for a very attractive sub-$40K luxury sports sedan. Its cabin gadgetry is nearly flawless, but the five-speed automatic mated to the drive-by-wire throttle detracts from the sports car experience.

The Bottom Line: With plenty to wow us, there's very little we can find at fault with the 2007 Lexus LS 460L. It comes up to par with other luxury sedans in its class, then beats them all with a substantially lower price.

Specs: Sedan, L, Gas

The Bottom Line: The 2006 Lexus IS 350 uses the highest-quality cabin electronics, and its strong engine and good handling make it a lot of fun to drive. At its relatively low price, it is one of the best values in a luxury sport car we've seen.

Specs: 350, Gas

The Bottom Line: With more horsepower than most sports sedans, a hybrid engine, and a long list of tech features, the Lexus GS 450h is a consummate package of comfort, performance, and technology.
