The original Range Rover was the world's first luxury 4x4 when it was launched in 1970. There have been three new distinct versions, with the most recent model unveiled in 2002. Since the release of the latest version, sales of Range Rovers have been running at record levels.

The 2007 model year upgrades come on top of a number of major improvements for the 2006 model year, when two new petrol engines were introduced. Both give better performance and greater fuel economy than the single V8 they replaced. The flagship model uses a 396 bhp/PS (291 kW) 4.2-litre supercharged V8, which is 35 per cent more powerful than the previous engine, has over 25 per cent more torque - which contributes to refinement and ease of driving - and is about 1.5 seconds quicker from 0-62 mph (100 km/h).

The other V8 is the normally aspirated 306 bhp/PS (225 kW) 4.4-litre engine, also quicker, more refined and more economical than the previous engine.

For the Range Rover Vogue these two Jaguar-derived engines were specially developed to offer more torque at lower revs. For tough off-roading, the engines can operate at more extreme angles and have enhanced protection from dust and rocks. They are also better water-proofed for Land Rover's tough wading requirements.

"Supreme breadth of capability is a hallmark of the Range Rover Vogue," says Land Rover managing director Phil Popham. "It inspires a sense of confidence no matter what the conditions. The latest Range Rover Vogue offers effortless performance, irrespective of terrain, and has better on-road performance than ever before, both in handling and straight-line speed.

"The new TDV8 model has the finest blend of performance and economy ever offered on a Land Rover vehicle. It is faster, quieter and more refined than any diesel engine in our history, and is exactly the right powerplant to underline the Range Rover Vogue's reputation as the world's most complete luxury 4x4."
