The 2010 Lexus LS range bristles with gas or hybrid powertrain technology, exudes world-class fit and finish, and keeps driving dynamics well-muted as it hits mid-life. New in 2007, the current LS is among the quietest sedans you can experience, and in either V-8 or V-8 hybrid form, it's at least as swift as the competition's standard-issue four-doors. And while it lacks the opulent touches of a Jaguar or an Audi, the long-wheelbase LS' backseat takes a backseat to none.

The 2010 Lexus LS 600h L teams a 5.0-liter V-8 engine and a hybrid drive system for V-12-like power. The gasoline V-8 makes 389 horsepower on its own, but altogether the system achieves 438 horsepower. Altogether, the LS 600h L moves quickly, with an almost eerie quiet; the only time you hear the gasoline engine is when accelerating hard. Lexus claims a 0-60 mph run of 5.5 seconds. Surprisingly, the LS 600h delivers better fuel economy than many V-8s, at 20/22 mpg.

The full-hybrid system can operate for short distances, almost silently, on electric power alone. There's even an EV button-a feature never before used on a Toyota hybrid in the U.S. market-that forces the system to use only electric power for several minutes. It recharges its nickel-metal-hydride battery packs either via the engine or through a regenerative braking system.

Prices soar to $109,000 for the hybrid model.
