Jaguar power for new Range Rover

The revised Range Rover gains two new Jaguar-sourced engines when it goes on sale this spring.

The new petrol units offer more performance and are predicted to have better fuel economy than the single outgoing V8 petrol. Now heading the line-up is a supercharged 291 kW (400 bhp SAE) 4.2-litre engine, with maximum torque of 560 Nm (420 lb ft SAE).

It offers over 35 percent more power than the outgoing V8, over 25 percent more torque – which contributes to more refined driving – and is projected to be around 1.5 seconds faster from 0-100 km/h (0-62 mph).

The new, naturally aspirated 225 kW (305 bhp SAE) 4.4-litre V8 is also quicker and more powerful than the outgoing V8. The 0-100 km/h (0-62 mph) acceleration time is projected to be around half-a-second faster and maximum power is increased by 15 kW (20 bhp).

Both engines are lightweight and use advanced torque-based engine management systems that, together with drive-by-wire throttle control and variable camshaft phasing (on the naturally aspirated), continually adjust the engine to deliver optimum performance, fuel economy and emissions.

For the Range Rover, the engines have been further developed to offer more torque at lower revs and to operate at more extreme angles to cope with tough off-roading. They have enhanced protection from dust and rocks, and are also better water-proofed for Land Rover's tough river-wading requirements.

The new engines are matched to the latest-generation ZF six-speed automatic electronically controlled transmission, which offers outstanding smoothness and response. It uses a centre differential (now electronically controlled) that improves both off-road prowess and on-road handling. Low-range is also available for extreme off-roading.

Steering feel is enhanced and the air suspension with adjustable ride-height is improved, for even better on- and off-road performance and comfort.

In addition, the supercharged version gets performance Brembo front brakes for better stopping power, and revised suspension that delivers flatter handling, for superior high-speed on-road performance.

The Range Rover retains its iconic shape, but there are subtle yet distinct changes. All Range Rovers for the 2006 model year get a new front bumper design, new headlamps and tail-lights, a new front grille and revised power vents. New 18-inch and 19-inch alloy wheels are also available. The supercharged derivative gets distinctive, additional styling modifications, which include mesh-design front grille and power vents, and unique 20-inch alloy wheels.

Additional customer features available include a rear camera for easier reverse parking, a tyre pressure monitoring system and adaptive front headlamps that swivel when cornering, to improve illumination. A rear seat entertainment system is now available, with two headrest-mounted 6.5-inch screens, a six-disc DVD auto-changer, infra-red remote control, wireless headphones and sockets for auxiliary media sources (such as an MP3 player or games console).

The six-cylinder turbodiesel powertrain continues unchanged, though with the refreshed exterior design details and additional features for 2006.
