INTRODUCTION
The 2017-2018 Range Rover IV facelift, particularly the Long wheelbase variant powered by the 3.0L V6 supercharged engine, represented a refinement of the already highly successful fourth-generation Range Rover (introduced in 2012). Built on the 4×4 platform (often referred to as the L405), this iteration benefited from styling updates, technological enhancements, and improved efficiency. The 380 horsepower engine, coupled with a smooth-shifting eight-speed automatic transmission and Land Rover’s renowned all-wheel-drive system, provided a luxurious and capable driving experience. This specific configuration aimed to balance performance with fuel economy, making it a popular choice for buyers who desired a refined SUV without the higher running costs associated with the larger supercharged V8 or diesel options.
Powertrain & Engine Architecture
At the heart of this Range Rover variant lies the Jaguar Land Rover AJ306 engine, a 3.0-liter V6 engine utilizing a roots-type supercharger for forced induction. This engine, internally designated as 306PS, produces 380 horsepower and 450 Nm (331.9 lb-ft) of torque. The engine features direct fuel injection and variable valve timing, contributing to its responsiveness and efficiency. The supercharger, mounted centrally in the V, provides instant boost, minimizing turbo lag and delivering a linear power curve. The engine is longitudinally mounted in the front of the vehicle. The eight-speed automatic transmission, sourced from ZF, is a key component of the powertrain. Known for its smooth and quick shifts, it contributes significantly to the vehicle’s refined driving experience. The transmission features a wide gear ratio spread, optimizing both acceleration and fuel economy.
Driving Characteristics
The 3.0L V6 supercharged engine delivers brisk acceleration, achieving 0-60 mph in approximately 7.4 seconds. While not as overtly powerful as the Range Rover’s V8 options, the V6 provides ample power for everyday driving and confident overtaking maneuvers. The supercharger ensures strong low-end torque, making the vehicle feel responsive even at lower speeds. The eight-speed automatic transmission seamlessly manages power delivery, and the all-wheel-drive system provides excellent traction in various conditions. The air suspension, standard on this trim, contributes to a comfortable ride, absorbing bumps and imperfections in the road. Compared to the higher-output V8 models, the V6 offers a more balanced driving experience, prioritizing refinement and efficiency over outright performance. The manual transmission was not offered in this configuration in the US market.
Equipment & Trim Levels
The 2017-2018 Range Rover IV Long 3.0 V6 Supercharged came generously equipped as standard. Key features included leather upholstery, heated front and rear seats, a panoramic sunroof, a premium sound system, and a touchscreen infotainment system with navigation. Standard safety features included a suite of driver-assistance systems, such as lane departure warning, automatic emergency braking, and adaptive cruise control. Optional extras included upgraded leather trim, rear-seat entertainment, and a variety of exterior styling enhancements. The Long wheelbase model specifically focused on rear passenger comfort, offering increased legroom and available executive rear seating packages with individual climate control and massage functions.
Chassis & Braking
The Range Rover IV utilizes a robust aluminum monocoque chassis, contributing to its strength and relatively low weight. The suspension system features double-wishbone front suspension and an independent multi-link rear suspension, both incorporating air springs and adaptive dampers. This setup provides a comfortable ride and excellent handling characteristics. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The vehicle’s Terrain Response system allows the driver to select different driving modes optimized for various surfaces, such as grass, gravel, snow, mud, and sand.
Market Reception & Comparison
The Range Rover IV Long 3.0 V6 Supercharged was well-received by critics and consumers alike. It was praised for its luxurious interior, comfortable ride, and capable performance. Compared to the V8 models, the V6 offered a more affordable entry point into the Range Rover lineup without sacrificing too much in terms of refinement or capability. Fuel economy, while not exceptional, was better than the V8 options. Reliability was generally good, although some owners reported minor issues with the infotainment system and air suspension. Compared to competitors such as the Porsche Cayenne and BMW X5, the Range Rover offered a unique blend of luxury, off-road capability, and British heritage.
Legacy
The 3.0L V6 supercharged engine has proven to be a relatively reliable powertrain, although regular maintenance is crucial. The ZF eight-speed automatic transmission is known for its durability. In the used car market, these Range Rovers hold their value reasonably well, particularly well-maintained examples with low mileage. The combination of luxury, capability, and relative efficiency makes this variant a desirable choice for buyers seeking a premium SUV. While newer Range Rover models offer even more advanced technology and features, the 2017-2018 IV facelift remains a compelling option for those seeking a refined and capable luxury SUV.
