All new for 2008, the Lexus LX 570 replaces the LX 470 in the automaker's lineup and offers a more powerful engine as well as improved off-road capabilities. The big SUV's full-time four-wheel-drive system, for example, comes equipped with a Torsen limited-slip center differential, which automatically distributes power between the front and rear axles to improve traction on any surface.

In addition, a Hill-Start Assist Control system prevents the SUV from rolling backward on a slope when the driver switches between the brake and gas pedals, while an advanced suspension system with Active Height Control automatically raises and lowers the LX 570 to improve aerodynamics at cruising speeds and ensure optimal height over rough terrain.

A beefy 383-horsepower, 5.7-liter V8 engine drives the LX 570 (and gives the SUV the numerical part of its name). The engine comes equipped with dual Variable Valve Timing with intelligence, which automatically boosts performance at higher speeds and increases torque at lower speeds to improve towing power. (The SUV can tow up to 8,500 pounds.) A six-speed automatic transmission, which was designed for fuel efficiency, includes a sequential-shift feature, which enables the driver to select gears much like a manual transmission.

Outside, the LX 570 features a new design, with a more aggressive grille, an integrated rear spoiler, 20-inch alloy wheels, a metallic-finish roof rack, and a power rear liftgate. Other features include dual-swivel adaptive front headlights, which pivot as the driver turns the steering wheel to provide better illumination at night.

Inside, the LX 570 seats eight passengers comfortably in three rows of leather-trimmed seating. The front seats provide plenty of legroom as well as comfort, since they're heated and power-adjustable - 14-way on the driver's side, 12-way on the passenger's side. Power-sliding second- and third-row seats fold and stow away to provide additional cargo space.

Other interior features include walnut wood accents, a voice-activated navigation system with a backup camera, four-zone automatic climate control, power-adjustable mirrors, a power tilt-and-slide moonroof, and a nine-speaker audio system with a six-disc CD changer. Options include a 19-speaker Mark Levinson audio system as well as a rear-seat DVD entertainment system.
