Range Rover Evoque Comes With A Refined Diesel Engine


As a true Range Rover, the Evoque delivers the all-weather, all-surface capability that is a hallmark of the brand. In common with its larger siblings, the new model provides formidable all-terrain potential, enhanced by the latest version of the company’s signature Terrain ResponseTM system.

The Evoque was the first Range Rover to offer customers a choice between the standard, full-time, intelligent, four-wheel-drive system, which delivers outstanding performance and traction on all surfaces, and a low-carbon, two-wheel-drive option for further enhanced fuel economy.

The diesel powered Evoque feature the latest 2.2-litre turbodiesel, available in 190PS (SD4), 150PS (TD4) and high-economy 150PS (eD4) derivatives, which delivers an excellent balance of strong, high-torque performance, impressive refinement and outstanding fuel economy.


The 2.2 turbodiesel range has been comprehensively updated to provide significantly more power, a very broad torque curve, further reduced noise levels and lower CO2 emissions. Over 60 per cent of components are either all-new or significantly modified.

The sophisticated power unit engine features high-pressure common-rail fuel injection with piezoelectric injectors, a variable nozzle turbine (VNT) turbocharger, a variable swirl system and an uprated engine management system for optimum combustion efficiency.


Very low noise levels and impressive smoothness are achieved through technologies like a double-walled cylinder block and twin balancer shafts.

Innovations introduced in the latest version include new low-noise injectors, a water cooled turbo for improved performance, reduced piston friction for optimised efficiency, new EGR system for lower particulates, lighter engine components, faster glow plug operation, and enhanced NVH measures.

The SD4 engine achieves outstanding fuel economy and CO2 emissions, with a CO2 output of 149g/km.


Range Rover engineers have applied meticulous attention to detail to ensure that the Evoque displays a refined and harmonious sound quality under all driving conditions.

Innovative technologies, including advanced computer simulations and painstaking optimisation using state-of-the-art analysis tools like sophisticated acoustic cameras, have been used to identify and remove all undesirable sounds.

The advanced turbocharged diesel engine is both inherently quiet and smooth, but further careful optimisation of the engine installations has made it possible to reduce powertrain sound levels to best-in-class levels. All sources of unwanted noise have been isolated or eliminated, resulting in a refined sound quality across the full operating range.

Wind noise has been minimised through analysis with computational fluid dynamics, and exhaustive wind tunnel tests. Key areas, such as the shape of the A-pillar and door mirrors, were optimised very early in the development process.

A special acoustic windscreen lamination, as used on the larger Range Rovers, further reduces wind noise and also helps to eliminate high-frequency combustion noise.

Road noise in the Evoque has been comprehensively managed through the use of stiff, lightweight alloy suspension components, along with carefully optimised bushes. These features work in conjunction with extremely stiff suspension attachment points within the bodyshell and accurately applied sprayed insulation material, to further minimise NVH.

All other operating sounds within the car, from door closing sounds to the noises made by switches and motors, have been analysed and refined during the development process to create a harmonious and premium sound quality for all occupants.
