The Range Rover has been revised for the 2006 model year, with two new petrol engines and numerous detail changes.
The Range Rover gains two Jaguar-derived petrol engines, which 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 400 bhp 4.2-litre engine, with maximum torque of 420 lb ft. It offers over 35 percent more power than the outgoing V8, over 25 percent more torque, and is projected to be around 1.5 seconds faster from 0-62 mph.
The new, naturally aspirated 305 bhp 4.4-litre V8 is also quicker and more powerful than the outgoing V8. The 0-62 mph time is projected to be around half-a-second faster and maximum power is increased by 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 Jaguar-sourced 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. The six-cylinder turbodiesel powertrain continues unchanged.
The new engines are matched to the latest-generation ZF six-speed automatic electronically controlled transmission, which now drives through an electronically-controlled centre differential. Low-range is also available for extreme off-roading.
Both steering and air suspension have been revised to improve performance and comfort. The supercharged version gets Brembo front brakes, too.
The exterior sees subtle styling changes, with 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 version also gets a mesh-design front grille and power vents, and unique 20-inch alloy wheels.
The interior styling remains unchanged, although the supercharged model does offer two new trim colour combinations – jet/jet (all black) and ivory/jet. Black lacquer wood is also now available, and all supercharged vehicles get special sports-designed stainless steel accelerator and brake pedals.
To reduce interior noise, the front side glass is now laminated and the profile of the A-post has been modified to reduce wind noise.
Additional equipment includes a rear camera for easier reverse parking, a tyre pressure monitoring system and adaptive front headlamps that swivel when cornering. 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 in-car phone is now Bluetooth-enabled and can be voice, touch-screen or steering wheel operated. Cradle-mounted phone handsets also allow for SMS text messaging (via an on-screen keyboard). A new, easy-to-use touch-screen is standard on all derivatives.
Sales of the latest Range Rover models commence in spring 2005, depending on market.
