Powertrain & Engine Architecture
At the heart of the Range Rover IV Long 5.0 V8 lies Land Rover’s AJ-V8 engine, specifically the 508PS variant. This engine is a 90-degree V8 featuring a Roots-type supercharger, providing instant throttle response and a broad torque curve. The 5.0-liter displacement is achieved with a bore of 92.5mm and a stroke of 93mm. Fuel is delivered via multi-port fuel injection, and the engine utilizes variable valve timing on both intake and exhaust valves. The engine is longitudinally mounted in the chassis. Paired with this engine is ZF’s 8HP70 eight-speed automatic transmission, known for its smooth shifts and efficiency. This transmission features a wide gear ratio spread, contributing to both performance and fuel economy. The transmission is electronically controlled and adapts to driving conditions.
Driving Characteristics
The combination of the 510 hp V8 and the eight-speed automatic delivers impressive performance. Acceleration from 0-60 mph is achieved in around 5.5 seconds, making it a genuinely quick SUV. The supercharger eliminates much of the turbo lag often associated with forced induction, providing immediate power delivery. The automatic transmission is well-tuned for both relaxed cruising and spirited driving. While not as engaging as a manual transmission, the eight-speed unit offers responsive shifts and allows the engine to remain in its optimal power band. Compared to the 3.0-liter SDV6 diesel variants, the V8 offers significantly more power and a more refined driving experience, albeit at the cost of fuel economy. The V8 also feels more effortless when towing or carrying a full load.
Equipment & Trim Levels
The Range Rover IV Long 5.0 V8 typically came standard with a high level of equipment. Interior features included leather upholstery (often semi-aniline leather), heated and ventilated front seats with massage function, a premium Meridian audio system, and a panoramic sunroof. The infotainment system featured a touchscreen display with navigation, Bluetooth connectivity, and a rear-seat entertainment system. Optional extras included executive rear seating with individual climate control and massage functions, a split-tailgate, and various exterior styling enhancements. Trim levels varied slightly by market, but generally, this engine was offered in the higher specification HSE and Autobiography trims.
Chassis & Braking
The Range Rover IV Long utilizes a full aluminum monocoque chassis, contributing to its relatively low weight for a vehicle of its size. The suspension system features air suspension with electronic dampers, providing a comfortable ride and the ability to adjust ride height for off-road use. All-wheel drive is standard, with a sophisticated Terrain Response system allowing the driver to select different driving modes optimized for various surfaces. Braking duties are handled by ventilated discs on all four wheels, with ABS and electronic stability control as standard features. The long wheelbase variant benefits from a slightly softer suspension tune compared to the standard wheelbase model, further enhancing ride comfort.
Market Reception & Comparison
The Range Rover IV Long 5.0 V8 was generally well-received by automotive critics. It was praised for its luxurious interior, powerful engine, and impressive off-road capability. However, its fuel economy was often criticized, as was its relatively high price tag. Compared to the diesel variants, the V8 offered a more prestigious driving experience but came with a significant fuel cost penalty. Reliability was generally good, although some owners reported issues with the air suspension system and electronic components.
Legacy
The Range Rover IV Long 5.0 V8 remains a desirable vehicle in the used car market. Its combination of luxury, performance, and off-road capability continues to appeal to buyers seeking a high-end SUV. The 5.0-liter supercharged V8 engine is known for its durability, although regular maintenance is essential. While newer Range Rover models offer more advanced technology and improved fuel economy, the fourth-generation Range Rover IV Long 5.0 V8 represents a sweet spot for many enthusiasts, offering a classic Range Rover experience with modern levels of comfort and refinement. Finding well-maintained examples is key, as the complexity of the vehicle means that servicing can be expensive.
