The Range Rover Sport is available in two models, HSE and Supercharged trims. The Sport maintains a shorter wheelbase than the full-size Range Rover and features such standard equipment as an electronic air suspension, speed sensitive variable ratio steering, 20-inch wheels (Supercharged model), hill decent control, high intensity discharge headlights, and a premium Harman/Kardon LOGIC7 sound system. A DVD based navigation system with voice recognition and a seven-inch LCD screen is also standard. The Cold Climate Package, featuring heated seats, a heated windshield screen, and heated washer jets, is optional on the HSE and standard on the Supercharged model.
