Land Rover's luxury mud-plugging image isn't fairing well in an era of high gas prices and eco concerns, so its rolled out two new technologies at the London Motor Show to prove that the automaker has its eye on a sustainable future.

Two LR2 prototypes are on hand featuring a parallel hybrid system mated to a turbo diesel engine. Testing is currently underway and so far, LR has seen a reduction in CO2 emissions by up to 20 percent. The Electric Rear Axle Drive (ERAD), originally shown on the LRX concept, can deliver power to all four wheels through a 288-volt electric motor producing around 150 lb.-ft. of torque. When complete, the system is expected to proliferate across the Land Rover line-up, along with a new lightweight architecture and a refined start-stop system, under the banner of e_Terrain Technologies.

The second development is the Crankshaft Integrated Starter Generator (CISG), which incorporates an electric motor into a dual clutch transmission, giving a boost in torque and starting the diesel mill.

Both systems aren't going to be ready for primetime for a few more years, but Land Rover's start-stop technology should find its way to production sometime next year.
