Powertrain & Engine Architecture
The heart of the D350 is Land Rover’s Ingenium engine family, specifically the DT306, a 2.997-liter inline-six cylinder diesel. This engine utilizes a sophisticated diesel commonrail fuel injection system and a variable geometry turbocharger to deliver a substantial 351 horsepower at 4000 rpm and a robust 700 Nm (516 lb-ft) of torque between 1500 and 3000 rpm. The high compression ratio of 15.5:1 contributes to its efficiency. The “mild hybrid” aspect comes from an integrated belt starter generator (BSG) which assists the engine during acceleration and allows for smoother start-stop operation, improving fuel economy. The engine is longitudinally mounted in the front of the vehicle. The eight-speed automatic transmission, sourced from ZF, is a crucial component, providing smooth and efficient gear changes. Its gear ratios are tuned to balance performance and fuel economy, with a focus on maximizing torque delivery for both on-road and off-road driving.
Driving Characteristics
The 3.0 D350 offers a compelling driving experience. While not as overtly sporty as the supercharged gasoline variants, it provides ample power for effortless cruising and confident overtaking. The readily available torque from the diesel engine, combined with the eight-speed automatic, results in strong acceleration – 0 to 60 mph in approximately 6.7 seconds. The automatic transmission is well-programmed, offering seamless shifts and responsive performance. Compared to the lower-powered diesel versions, the D350 feels significantly more capable, particularly when fully loaded or towing. The mild hybrid system contributes to a refined driving experience, minimizing vibrations and providing a near-silent start-stop operation. The Range Rover’s air suspension ensures a comfortable ride, even on rough terrain.
Equipment & Trim Levels
The D350 trim typically included a high level of standard equipment. This generally encompassed leather upholstery, heated and ventilated front seats, a premium sound system, a touchscreen infotainment system with navigation, and a comprehensive suite of driver-assistance features such as adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras included features like a panoramic sunroof, upgraded leather trim, rear-seat entertainment, and various off-road packages. The interior design emphasized luxury and comfort, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The Range Rover IV’s chassis is built around a lightweight aluminum monocoque construction, contributing to its impressive strength and rigidity. The D350 variant featured a sophisticated suspension system, including air suspension with electronic dampers, providing a comfortable ride and excellent off-road capability. Braking duties were handled by ventilated discs on all four wheels, with larger front discs (380mm) than the rear (365mm). The braking system was augmented by ABS, electronic brake-force distribution, and brake assist. Stabilizer bars were fitted front and rear to minimize body roll during cornering.
Market Reception & Comparison
The Range Rover IV D350 was generally well-received by automotive critics. It was praised for its blend of performance, refinement, and fuel efficiency. Compared to the lower-powered diesel models, the D350 offered a noticeable performance upgrade without the higher running costs of the supercharged gasoline engines. Fuel economy, while not exceptional, was respectable for a vehicle of its size and capability, averaging around 25.6-24 US mpg in combined driving. Reliability was generally good, although, as with any complex vehicle, some owners reported issues with the electronic systems.
Legacy
The Ingenium diesel engine, as featured in the D350, has proven to be a robust and reliable powerplant. While diesel engines have faced increasing scrutiny in recent years, the D350 remains a desirable option in the used car market, particularly for those seeking a luxurious and capable SUV with good long-distance cruising ability. The mild hybrid technology, while not as impactful as a full hybrid system, contributes to improved fuel economy and reduced emissions. The Range Rover IV D350 represents a high point in the evolution of the Range Rover, combining traditional luxury with modern technology.
