Land Rover diet loses 1000 lbs
As they further point out, the Discovery and Range Rover Sport are both due for replacement a couple of years after the Range Rover, and it would make economic sense to share the technology across as many models as possible to exact the best economies of scale for L-R. It was expected that the new RR might switch to Land Rover's semi-monocoque steel T5 platform, which underpins the Discovery and the Range Rover Sport, but this makes a whole lot more sense.
Curb weight for the current Range Rover is about 6,000 pounds, but with a similar 15% weight savings as Jag has witnessed, Land Rover could get that down to less than 5,000 while maintaining the off-road toughness for which its vehicles are known. The boost in fuel economy and performance wouldn't hurt either.
