INTRODUCTION
The 2017-2018 Range Rover IV Long 4.4 V8 Diesel represented a significant offering in the luxury SUV segment. Built on the 4HX platform, this facelift brought updated styling, enhanced technology, and refined powertrain options. The 4.4-liter V8 diesel engine, coupled with an eight-speed automatic transmission and all-wheel drive, provided a compelling combination of performance and efficiency. The “Long” wheelbase version specifically targeted buyers who prioritized rear passenger space, making it a popular choice for those utilizing the vehicle for executive transport or long-distance family travel. This variant was positioned as a premium offering, sitting above the four and six-cylinder diesel models in terms of price and features.
Powertrain & Engine Architecture
At the heart of this Range Rover variant lies the 448DT 4.4-liter V8 diesel engine. This engine utilizes a sophisticated common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The engine is equipped with a sequential twin-turbocharger setup with variable geometry turbines (VGT), along with an intercooler, to maximize power and torque while minimizing turbo lag. The engine boasts a high compression ratio of 16:1, contributing to its efficiency. The eight-speed automatic transmission, sourced from ZF, is a crucial component of the powertrain. Known for its smooth and responsive shifts, it features a wide gear ratio spread, optimizing both acceleration and fuel economy. The transmission is electronically controlled and adapts to driving conditions and driver input.
Driving Characteristics
The 4.4 V8 diesel in the Range Rover IV Long delivers a substantial 740 Nm (545.8 lb-ft) of torque, providing effortless acceleration and strong pulling power. While not as overtly sporty as some of its gasoline-powered counterparts, the diesel engine offers a relaxed and refined driving experience. The eight-speed automatic transmission contributes to this smoothness, providing seamless gear changes. The long wheelbase does slightly impact agility compared to the standard wheelbase model, but the air suspension system effectively mitigates body roll and provides a comfortable ride. The all-wheel-drive system ensures excellent traction in various conditions, making it capable both on and off-road. The 0-60 mph time of around 6.8 seconds is respectable for a large, luxurious SUV.
Equipment & Trim Levels
The Range Rover IV Long 4.4 V8 Automatic came standard with a high level of equipment. Interior features typically included premium leather upholstery, heated and ventilated front and rear seats, a panoramic sunroof, and a sophisticated infotainment system with navigation. Standard safety features included a suite of driver-assistance systems, such as adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras included upgraded audio systems (Meridian), rear-seat entertainment, and various customization options for interior trim and exterior styling. The Long wheelbase models often featured executive rear seating packages with individual seats, massage functions, and increased legroom.
Chassis & Braking
The Range Rover IV utilizes a robust chassis construction, combining high-strength steel with aluminum components to achieve a balance of strength and weight reduction. The suspension system features air suspension with electronic dampers, providing a supremely comfortable ride and the ability to adjust ride height. The front suspension employs a double-wishbone design, while the rear utilizes an independent multi-link setup. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The electronic stability control system and anti-lock braking system (ABS) work in conjunction to enhance safety and control.
Market Reception & Comparison
The Range Rover IV Long 4.4 V8 Diesel was generally well-received by automotive critics. It was praised for its luxurious interior, comfortable ride, and powerful engine. However, some reviewers noted the relatively high price tag and the complexity of the vehicle’s technology. Compared to the other engines in the Range Rover IV lineup, the 4.4 V8 diesel offered a significant performance advantage over the four and six-cylinder diesels, while providing comparable fuel economy. It was positioned as a direct competitor to other luxury SUVs, such as the BMW X7, Mercedes-Benz GLS, and Audi Q7.
Legacy
The 448DT 4.4-liter V8 diesel engine has proven to be a relatively reliable powertrain, although it is not without its potential issues. Common concerns include diesel particulate filter (DPF) clogging and injector failures, particularly if the vehicle is not properly maintained. The eight-speed ZF automatic transmission is generally considered to be very durable. In the used car market, the Range Rover IV Long 4.4 V8 Diesel holds its value relatively well, due to its desirable combination of luxury, performance, and space. However, potential buyers should be aware of the potential maintenance costs associated with a complex vehicle like the Range Rover.
