Land Rover Range Rover Sport 2010

Auto Car | Land Rover Range Rover Sport 2010 | The Range Rover Sport reaffirms its status as the most exciting and dynamic member of the Land Rover range with a comprehensive package of engineering and design changes for the 2010 model year. The vehicle’s stylish new appearance signals the transformation under the skin, which includes two powerful and efficient new engines – the LR-TDV6 diesel and LR-V8 5.0-litre supercharged – enhanced levels of interior craftsmanship and refinement, and significant improvements to both on-road and off-road driving dynamics.



The vehicle retains the acclaimed LR-TDV8 diesel engine and this model also benefits from upgrades to the design and under-the-skin enhancements. A comprehensive programme of chassis system modifications has transformed the Range Rover Sport’s on-road dynamics, while also delivering a substantial improvement in its off-road capabilities.The introduction of new systems such as Adaptive Dynamics, working in conjunction with the existing Dynamic Response, known as active ride control (ARC) on Supercharged models, and the addition of the road-focused Dynamic Program to the Terrain Response™ system help enhance agility and ride quality. Further improvements to the Terrain Response™ system ensure that off-road capability is kept at the expected class-leading level.



The Range Rover Sport’s stylish, muscular exterior has been updated to provide a cleaner, more sculpted feel. Striking signature LED headlamps combine with a new two-bar grille, front bumpers and wings to create a more sporting and aerodynamic stance. At the rear, new light clusters and a revised bumper design mirror the smoother front end.The interior has been comprehensively redesigned, using higher quality materials, soft-touch finishes and superior craftsmanship to create a premium environment which is truly worthy of the Range Rover brand.“The Range Rover Sport has generated a passionate following among customers who require the performance and refinement of a true sports tourer but who value the formidable off-road ability of a Land Rover.  Now that we have widened its range of capabilities even further, the following for the Range Rover Sport looks set to grow stronger still.” Phil Popham, Managing Director, Land Rover Under the banner of e_TERRAIN TECHNOLOGIES, Land Rover is implementing a range of measures to reduce fuel consumption and CO2 emissions, without compromising the Range Rover Sport’s renowned dynamic driving characteristics and all-terrain capabilities.
Both the new LR-V8 supercharged petrol engine and the LR-TDV6 3.0 sequential turbodiesel were designed from the outset to deliver class-leading fuel economy and improved low-end torque. The LR-V8’s new, high-pressure, spray-guided direct injection system optimises combustion and the engine is fitted with a new variable camshaft timing system as well as a sixth-generation, twin-vortex supercharger whose high-helix rotor design improves its thermodynamic efficiency by 16 per cent.   Faster warm-up thanks to the new cooling system also improves fuel economy, as do the low-friction design features.



The parallel sequential turbocharging system of the 3.0-litre diesel makes use of its larger, primary turbo most of the time. The smaller, secondary turbo remains dormant when higher power is not required, reducing pumping losses and, consequently, fuel consumption. A highly efficient, third-generation common-rail injection system with piezo injectors and fuel metering also makes a substantial contribution to fuel economy. The new engines have been optimised for low-end torque as well as economy, making it possible to activate the lock-up clutch of the ZF HP28 automatic transmission at lower speed. This reduces slip in the hydraulic torque converter, improving both fuel consumption and CO2 emissions. The higher torque at lower rpm also enables longer gearing for more economical cruising.



The Range Rover Sport incorporates several other energy-saving features too. At standstill, the idle speed of the LR-TDV6 has been reduced from 750 rpm to 710 rpm, while that of the LR-V8 has been reduced from 700 rpm to 600 rpm. In both cases, a fuel saving is made without compromising refinement. Intelligent Power System Management (IPSM) includes smart regenerative charging, in which the alternator charges the battery when it is most economical to do so, such as when the vehicle is coasting rather than accelerating.  The air conditioning pump on the new LR-TDV6 3.0-litre engine is now driven through a clutch, which disengages when the air conditioning is not in use, making further fuel consumption savings.
