This five-passenger wagon fills a price gap between Land Rover's LR3 and its ultraluxury Range Rover models, but is smaller than either and competes with sporty SUVs such as the BMW X5 and Porsche Cayenne. Based on LR3's underskin architecture, Range Rover Sport comes as the HSE model with a 300-hp V8 and as the Supercharged version with a 390-hp V8. Both engines are sourced from Jaguar, which is owned by Land Rover's parent company, Ford. A 6-speed automatic is the sole transmission. All-wheel drive with low-range gearing is standard and includes Land Rover's Terrain Response system, designed to automatically tailor AWD performance to specific off-road conditions. Also included are ABS, height-adjustable air suspension, and traction/antiskid control. So are front side airbags, curtain side airbags, and a navigation system. Standard on Supercharged, available on HSE are wood interior trim, heated seats, and Land Rover's Dynamic Response suspension system designed to counteract body lean in turns. DVD entertainment is optional.
