The 2013 Range Rover is inching closer to production as our spies have caught another prototype undergoing cold weather testing.

The 2013 Range Rover is inching closer to production as our spies have caught another prototype undergoing cold weather testing.

Heavily disguised, the model has an evolutionary design with prominent headlights, a clamshell hood and a sloping roofline. We can also see large door mirrors and vertical taillights.

The Range Rover is expected to grow in size, but the model will reportedly ride on an aluminum-intensive platform that was co-developed with Jaguar. This could enable the SUV to weigh 400 kg (882 lbs) less than its predecessor.

Engine options will likely carryover, but we can expect to see a plug-in hybrid variant which borrows some technology from the Range_e concept.
