VEHICLE HIGHLIGHTS, A locking center differential and a new off-road-inspired version highlight 2004 additions to Land Rover's oldest SUV. In price and dimensions, Discovery falls between Land Rover's Freelander and Range Rover. It comes in S, SE, and top-line HSE models. An available 3rd-row seat increases passenger capacity from five to seven, adding a '7' suffix to the badge. SE and HSE have wood and leather interior trim and dual sunroofs. A 217-hp 4.6-liter V8 is the sole engine, a 4-speed automatic the only transmission. All-wheel drive with low-range gearing and traction control is standard. For '04, the system gains a driver-activated center differential that locks in a 50/50 front/rear torque split for enhanced off-road traction. Dropped for '04 is Land Rover's Active Cornering Enhancement (ACE), which used hydraulic suspension levers to reduce body lean in turns. The S model has 16-inch alloy wheels, the others have 18s. ABS is standard. Self-leveling suspension and a rear-obstacle-detection system are standard on HSE, optional for the others. A navigation system is standard on HSE and optional on SE; rear DVD entertainment is available on both. Also new for '04 is a limited run of 200 G4 Editions, named for the Land Rover-sponsored off-road challenge. They're painted orange and include self-leveling suspension, front brush bar, rear access ladder and lamp guards, and unique cloth upholstery. Land Rover is owned by Ford.
