NEW RANGE ROVER SPORT | POWERTRAIN
The All-New Range Rover Sport features an enhanced line-up of powerful petrol and diesel engines 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.
Among the powertrain innovations on the new Sport is the availability of the all-new 340PS 3.0-litre supercharged V6 petrol engine, the return of the SDV8 turbodiesel next year with its massive reserves of torque.
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.
Formidable 510PS Supercharged V8
The 510PS 5.0-litre V8 supercharged engine retains its place at the performance pinnacle of the Range Rover Sport line-up. With huge reserves of power and torque, the scale of the performance on offer is reflected in the 0-60mph time of sub-5.0 seconds (0.9 seconds faster than the outgoing model) – achieved with a rich sporting soundtrack generated by a carefully tuned exhaust system and sound symposer on the intake system.
Despite the performance boost, fuel efficiency has been improved by 14 percent over the outgoing model, with CO2 emissions of 298g/km.
The V8 has a compact and lightweight all-aluminium design, with class-leading low levels of internal friction. For the new Sport, the engine has been re-optimised around a state-of-the-art new Bosch engine management system.
The engine features high-pressure direct injection with an industry-leading centrally-mounted, multi-hole, spray-guided injection system. Efficiency is further enhanced by an innovative (cam torque actuated) dual independent variable camshaft timing system (VCT). A sixth-generation, twin vortex system (TVS) supercharger is fitted, which offers superior thermodynamic efficiency and extremely refined noise levels.
New 3.0-litre Supercharged V6
Available on the Sport for the first time, the 340PS 3.0-litre V6 is a state-of-the-art new supercharged petrol engine for markets favouring smaller capacity units.
The new engine has been engineered to deliver generous torque throughout the rev range, delivering confident performance with outstanding refinement. With this engine, the new Sport is quicker than the previous Sport with the 375PS 5.0-litre V8, achieving the dash from 0-60mph in 6.9 seconds, a reduction of 0.3 seconds. Enthusiastic drivers will also be pleased with the attractive sporting engine note, emphasised using a sound symposer on the intake system.
The advanced V6 engine design is extremely efficient, achieving CO2 emissions of 249g/km, a dramatic reduction of 24 percent over the outgoing 375PS V8 model.
The new V6 uses a modular design based on the advanced V8 supercharged engine, sharing that engine’s lightweight all-aluminium construction and leading-edge technologies.
Unique features introduced on the V6 include an innovative balance weight system to ensure exceptionally smooth and refined performance.
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.
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
Scheduled to make its return to the Range Rover Sport line-up early in 2014, 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.
Advanced 8-speed automatic transmission
All petrol and diesel engines in the new Range Rover Sport are paired with the advanced electronically controlled ZF 8HP70 8-speed automatic gearbox, which has been tuned by Land Rover engineers to combine silky-smooth shifting with exceptionally rapid responses and outstanding fuel economy. With eight closely-spaced ratios, gearchanges are almost imperceptible, with each shift completed in just 200 milliseconds.
Controls include the sporting vertical gear shifter, plus the option of steering wheel-mounted paddle-shift. Either system enables the driver to take control of gear shifting manually – the transmission will also accept multiple downshifts, maintaining an absolutely smooth transition between ratios.
The transmission is tuned to select torque converter lock-up as early as possible to reduce slip and energy loss. The wider ratio spread, tall ‘overdrive’ top ratio and the fact that no more than two internal clutches are open at any one time, all contribute to improved fuel economy and lower emissions.
Transmission Idle Control disengages 70 percent of the drive when the vehicle is stationary and the engine is idling in Drive, significantly reducing consumption in urban conditions. In cold conditions, the transmission selects a lower gear to speed warm up and quickly get the engine up to its efficient operating temperature.
The hydraulic actuating system has been designed for increased efficiency, with improved pump design and gear control elements.
