Full details of the all-new Range Rover have been released – and the bad news is you'll desperately want to find the £71,000 needed to buy one.

One of the most desirable four-wheel drives around, this is the fourth generation of the popular model and boasts a new look, new technology and a hybrid engine option for the first time.

It's lighter, stronger and more refined than its predecessor thanks to an all-aluminium body which has helped shave a whopping 420kg over the outgoing model – that's almost as much as Morgan Three Wheeler!

"Launching the all-new Range Rover represents a major milestone for Land Rover, being the first exciting output from an unprecedented investment in premium vehicle technologies," said John Edwards, Land Rover's global brand director.

"The new Range Rover preserves the essential, unique character of the vehicle – that special blend of luxury, performance and unmatched all-terrain capability. However, its clean sheet design and revolutionary lightweight construction have enabled us to transform the experience for luxury vehicle customers, with a step change in comfort, refinement and handling."

There's a wide choice of engines including a supercharged 507bhp V8 capable of propelling the semi-detached house-sized motor to 60mph in just 5.1 seconds. Two diesel engines – a 255bhp TDV6 and a 336bhp SDV8 – are aloes available and all come with an eight speed automatic gearbox.

A diesel hybrid power train will join the line up later in 2013 which aims to produce just 169g/km.

As you'd expect for a premium car costing from £71,295, it's packed with kit. Highlights include a dual-view eight-inch screen which can display different things for the driver and passenger, keyless entry, soft-closing doors and voice control equipment.

A spokesman for Jaguar Land Rover added: "Order books are now officially open with the first months of production expected to fill up immediately.

"Sales of the outgoing Range Rover remain extremely strong. In the last 12 months we have sold more vehicles across the range than in any other rolling 12 month period, retailing nearly 280,000 units world-wide."

Production of the new Range Rover will also boost UK PLC with Jaguar Land Rover investing £370m into its UK manufacturing facilities.

As part of the investment package, JLR has installed a new aluminium bodyshop at the company's Solihull plant, near Birmingham.

Dr. Ralf Speth, Jaguar Land Rover CEO, added: "This outstanding new Range Rover symbolises our commitment to investing in Britain and exporting around the world."

First deliveries of the new model are expected later this year.
