Range Rover 2014 Diesel Powertrain Is Impressive
The new Range Rover delivers effortless performance and imperious refinement with its highly acclaimed line-up of torque-rich petrol and diesel engines, all of which are now paired with a smooth and responsive 8-speed automatic transmission.
The vehicle’s lightweight aluminium platform has helped to deliver significant enhancements in performance, fuel economy and CO2 emissions.
Among the powertrain innovations on the new Range Rover is the availability of the sophisticated Land Rover TDV6 diesel engine, which combines outstanding performance with exceptional efficiency, achieving CO2 emissions from 196g/km.
Refined and responsive TDV6 diesel
Available in the Range Rover for the first time, the refined and ultra-efficient 258PS 3.0-litre TDV6 diesel delivers effortless performance combined with unprecedented fuel economy and emissions.
The innovative lightweight technology of the new Range Rover enables the TDV6 engine to match the outstanding performance of the outgoing TDV8 model, while cutting fuel consumption and CO2 emissions by an amazing 22 per cent when equipped with stop/start, achieving 196g/km.
With a substantial maximum torque of 600Nm, the TDV6 is capable of refined and smoothly responsive performance, sweeping from 0 – 60 MPH in just 7.4 seconds. To achieve the unprecedented blend of refined performance and remarkable efficiency, the TDV6 engine has been extensively optimised for the new vehicle.
The engine 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 for further reduced fuel consumption and emissions. Like the SDV8, the V6 has been designed using the innovative parallel sequential turbocharging concept which delivers outstanding performance and responsiveness throughout the rev range.
Range Rover’s outstanding SDV8 diesel
The magnificent SDV8 diesel was designed exclusively for the Range Rover, and for the new model its power rises to an impressive 339PS, an increase of 9 per cent. The 4.4-litre ‘super-diesel’ combines huge reserves of power with impressively low emissions and unparalleled levels of refinement.
With a staggering 700Nm produced between 1750 and 3000rpm, the SDV8 delivers completely effortless performance, surging from 0-60 MPH in 6.5 seconds, a full 1.0 second faster than the outgoing model. The engine’s outstanding fuel efficiency is reflected in CO2 emissions of 229g/km, which represents a further reduction in emissions of 10 per cent over the outgoing model.
The SDV8 achieves its incomparable blend of supreme driveability and refinement through advanced diesel technologies, most notably the innovative parallel sequential turbocharging concept which delivers outstanding performance and responsiveness throughout the rev range. The power increase for the new Range Rover 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.
