New Engines Deliver Exceptional Performance and Economy
The most significant changes on the 2010 Range Rover Sport are to its powertrains. The vehicle benefits from two powerful new engines that combine refined performance with improved fuel efficiency and lower emissions: the 245 PS LR-TDV6 3.0 twin-turbo diesel and the 510 PS LR-V8 5.0 supercharged petrol.
The new 3.0-litre diesel features an innovative parallel sequential turbocharging system to deliver class-leading refinement and torque. Compared with the much acclaimed 2.7-litre diesel that this engine replaces, the 3.0-litre unit provides 29 per cent more power and 36 per cent more torque, while at the same time reducing CO2 emissions by 8.3 per cent to 243 g/km.
The 5.0-litre LR-V8 supercharged petrol engine is all-new and designed by the Jaguar Land Rover powertrain team using an impressive collection of state-of-the-art technologies. This engine was developed to deliver a smooth, refined and responsive driver experience, producing an impressive 510 PS and 625 Nm of torque.
Strong and Compact
The new LR-V8 engine is built around a stiff, all-new, aluminium block with cast-in iron liners and cross-bolted main bearing caps to reduce noise, vibration and harshness. For the first time at Land Rover, the blocks are high-pressure die-cast rather than sand-cast, providing a superior finish and greater dimensional accuracy. The engine also has aluminium heads, with four valves per cylinder and strong, spheroidal-graphite cast-iron crankshaft and steel connecting rods. The cylinder heads and block are manufactured using recycled aluminium alloy for the first time, thus reducing the environmental impact of manufacturing the new engine.
The new direct injection petrol engine is more compact than its predecessor. Overall engine length has been reduced by the relocation of the oil pump within the engine architecture.
Responsive New Transmission
Both the LR-V8 petrol and LR-TDV6 3.0-litre diesel engine on the Range Rover Sport are mated to the revised and super-smooth ZF HP28 six-speed automatic transmission. Its characteristics have been optimised by Land Rover engineers to provide class-leading response, with rapid and refined shifts. The dramatic enhancement of both power and torque low down the rev range on the new engines has made it possible to actuate the transmission's lock-up clutch much earlier in each gear, reducing slip through the hydraulic torque converter, and thereby helping with the improvements in both fuel consumption and CO2 emissions.
The transmission features an intelligent sport mode, which can sense and adapt transmission characteristics to particular driving styles. In addition, for the first time on the Range Rover Sport, the driver can change gears manually with the option of a steering wheel mounted paddle-shift.Published 8 April 2009
