Land Rover has officially unveiled images of its next-generation Range Rover for 2013, announcing the SUV will be both bigger and lighter than its predecessor.

The 2013 Range Rover has been designed and engineered on an all-aluminum unibody structure that is 39 percent lighter than the outgoing steel body.

This allowed Land Rover to knock off a total weight of up to 926lbs, depending on market and specifications. The U.S. market 5.0-litre V-8 Range Rover is about 318 kg (700 lbs) lighter than the 2012 equivalent, for example.

On the inside, the new 2013 Range Rover receives a bunch of upgrades and over 4.7 inches more legroom than the outgoing model.

The engine lineup remains the same as before, consisting of a supercharged V8 petrol engine, TDV6 and TDV8 diesel engines. But duo to the new featherweight structure, they are all much more economical now.

Full specifications and pricing details are expected to be released ahead of the vehicle’s formal unveiling at the Paris Motor Show in September, with deliveries to customers starting in early 2013.
