Land Rover's sport-oriented SUV is based on the underskin architecture of its larger, seven-passenger LR3. Range Rover Sport seats five. It 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. It includes Land Rover's Terrain Response system, which automatically tailors AWD performance to specific off-road conditions. A locking rear differential is optional. All Range Rover Sports have ABS, traction/antiskid control, front side airbags, and curtain side airbags. Height-adjustable air suspension and hill-descent control are standard, as are a sunroof, dual-zone climate control, front and rear obstacle detection, and a navigation system. Standard on Supercharged, available on HSE are wood interior trim, heated seats, steering-linked headlights, and Land Rover's Dynamic Response suspension system designed to counteract body lean in turns. DVD entertainment and adaptive cruise control are optional. For 2007, a wireless cell phone link moves from optional to standard.
