It's been no secret in recent years that Land Rover has been itching to reduce the weight of its products. Even before Ford sold the brand to Tata, it had been working on a variety of lighter weight concepts and it looks like the next-generation Range Rover will be the first benefactor of those efforts when it debuts in 2012.
The new flagship SUV is expected to cast a shadow similar to the current model, just with a lower roof. This should significantly reduce the frontal area and, therefore, the overall aerodynamic drag. Mass will be reduced by using a riveted aluminum chassis with the same type of construction as the Jaguar XJ. Composite materials will also play a part in the body panels. How much will these efforts save? Land Rover is apparently targeting a cut of 450 kilograms (992 pounds).

A 3.0-liter turbodiesel V6 engine that is now available in the Jaguar XF and XJ should bring CO2 emissions down from the the current 300+ grams / kilometer to under 200 g/km along with fuel economy of 33 mpg (U.S.). A diesel-hybrid is also expected in the lineup a couple of years after launch.
