The five-passenger Range Rover Sport is available in two trim levels: HSE and Supercharged. The HSE is powered by a 375-hp 5.0-liter naturally-aspirated V8 engine, while the Supercharged trim boasts a 510-hp 5.0-liter supercharged V8. Both powerplants feature direct fuel injection and are mated to a six-speed automatic transmission with CommandShift manual mode; additionally, Supercharged trims get steering wheel-mounted paddle shifters. Full-time four-wheel drive with Land Rover's acclaimed "Terrain Response" system helps tackle a wide range of off-road conditions, while Supercharged trims add Adaptive Dynamics with variable suspension dampening for sportier handling. Standard equipment on the HSE includes a power sunroof, 19-inch alloy wheels, bi-xenon headlights, LED tail lamps, leather upholstery, passive entry/start, a hard drive-based navigation system and a portable audio interface that supports USB and iPod connectivity. Supercharged trims are further outfitted with 20-inch wheels, heated front and rear seats, a heated steering wheel and satellite radio. Standard safety features include six airbags, four-wheel anti-lock brakes with brake assist, electronic stability control with traction control and roll mitigation, front and rear park assist and tire pressure monitoring. A new Vision Assist Package offers adaptive front lighting and automatic high beam assist, along with a surround camera system. After an extensive refresh last year, the Land Rover Range Rover Sport carries over with minimal changes for 2011. A new GT Limited Edition is offered, featuring a unique exterior style package, exclusive 20-inch wheels, leather and simulated suede seat upholstery and an upgraded audio system.
