Range Rover Sport 2014 Model Has Impressive Diesel Powertrain
The all-new Range Rover Sport features an enhanced line-up of powerful diesel engines, all available with diesel-saving Stop/Start paired with an advanced 8-speed ZF automatic transmission, which deliver outstanding performance with immediate responses and a dynamic and connected character. The substantial weight saving of up to 420kg delivered by the aluminium platform has helped to deliver a step change in the performance on offer, together with significant gains in fuel economy and CO2 emissions.
The weight reduction measures on the new Range Rover Sport open up the future possibility for the fitment of a smaller, lighter power plant, such as a four cylinder engine. A model which could have an overall weight of less than 2000kg, a reduction of over 500kg from the previous lightest model.
Responsive and ultra-efficient TDV6 / SDV6 turbodiesels
The responsive and ultra-efficient 3.0-litre V6 turbodiesel has been significantly upgraded for fitment in the new Range Rover Sport. The V6 is available in two versions (258PS TDV6 and 292PS SDV6) delivering major power increases over the equivalent units in the outgoing model which boasted 211PS and 256PS. With 600Nm of torque, both variants deliver outstanding performance along with exceptional efficiency. The SDV6 model hits 0-60mph in just 6.8 seconds and achieves CO2 emissions of 199g/km – down 13 percent.
The 258PS TDV6 reaches the same benchmark in 7.1 seconds with CO2 emissions of 194g/km, representing a 15 percent improvement over the same model. To achieve the unprecedented blend of refined performance and remarkable efficiency, the TDV6 engine has been extensively optimised for the new vehicle. It uses a new eight-nozzle low-flow injector design for more precise injection and improved fuel atomisation, a revised intake system with twin intercoolers offers enhanced charge cooling, and the engine features the latest tandem solenoid intelligent Stop/Start system. Both TDV6 and SDV6 variants feature the innovative parallel sequential turbocharging concept which delivers outstanding performance and responsiveness throughout the rev range.
Range Rover’s outstanding SDV8 turbodiesel
The much acclaimed 4.4-litre 339PS SDV8 diesel offers huge reserves of torque and completely effortless performance. Designed exclusively for Range Rover, the 4.4-litre ‘super-diesel’ develops a staggering 700Nm between 1750 and 3000rpm, surging from 0-60mph in just 6.5 seconds. The engine’s outstanding fuel efficiency is reflected in CO2 emissions of 229g/km. The SDV8 achieves its incomparable blend of supreme driveability and refinement through advanced diesel technologies, most notably innovative parallel sequential turbocharging.
The increased power output of the current version of the SDV8 engine was achieved through a revised intake system with twin intercoolers and an optimised calibration. The updated installation also achieves a 10kg weight saving, through the use of cast alloy engine mounts (in place of iron) and a redesigned sump.
