The New Range Rover's LR-V8 Engine

The 2010 Range Rover gets an all-new 5.0-litre LR-V8 supercharged petrol engine. The engine was developed in conjunction with Jaguar - the first time an engine has been designed from the outset with the requirements of both brands in mind. Shared primary objectives included the highest possible torque and fast response from low revs.

Although the basic architecture of the LR-V8 supercharged is the same for each brand, some changes were needed for the Land Rover engines to satisfy demanding all-terrain requirements. For example, the engines feature a deeper sump to accommodate the extreme tilting angles experienced when driving the Range Rover off road, and to accommodate the front differential which attaches to it. In addition, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor.

The supremely powerful supercharged LR-V8 delivers 510PS and 625Nm of torque. One of the most advanced petrol engines ever built, the engine is packed with innovative features to ensure that it is also one of the most frugal in its class.

The LR-V8 was developed with an emphasis on delivering a smooth, refined and responsive driver experience, with excellent power characteristics. Compared to the current 4.2-litre V8 the supercharged engine increases power and torque outputs by 29 per cent and 12 per cent respectively.

Despite this extra power, CO2 emissions are just 348g/km, 7.4 per cent lower than the 4.2-litre; fuel consumption is reduced by a similar amount. Yet when it comes to regulated emissions the engine is incredibly clean, meeting the EU 5 regulations not due to come into force until 2011.

The Range Rover's engine has also been designed around a 5W-20 semi-synthetic oil. The new oil has a lower viscosity, primarily at low temperatures, reducing parasitic losses in the engines and contributing to an extension in service intervals from 10,000 miles to 15,000 miles or 12 months. The new LR-V8 engine is also fitted with an electronic dipstick for added peace of mind.

Responsive New Transmission

The 2010 Range Rover's new petrol engine is mated to the revised and super-smooth ZF HP28 6-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 have made it possible to actuate the transmission's lock-up clutch much earlier in each gear, reducing slip through the hydraulic torque converter, so 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.

The Diesel Alternative

For customers who prefer diesel power, the acclaimed 272PS 3.6-litre TDV8 engine continues to be available on the 2010 Range Rover. It is paired with the smooth and responsive ZF HP26 6-speed automatic.
