110mpg from a Jeep?

OK so it's a concept at this stage but Jeep has unveiled an environmentally aware off-roader at the Detroit motor show.

Powered by a hybrid electric motor and 1.5l 3 cylinder diesel Jeep claim that the car is potentially capable of 110mpg.

What is interesting is that Jeep essentially gave birth to the "Chelsea Tractor" style of transport, and although this is an obviously lightweight concept it is all Jeep, so if the Daddy of the public enemy number 1 amongst environmentally aware urbanites is looking for ways to radically green up its oh so macho GRRRRRR range and to demonstrate that you don't need a 4 litre V8 for off-road fun (for the 0.1% that do drive them in the mud) then perhaps a few more manufacturers will get equally creative. Hybrid Hummer anyone?
