Geneva Motor Show 2008 Preview: BMW twin-turbo diesel hybrid X5

Every auto show nowadays has to have its fair share of "green" concepts, and Geneva won't be any different. Over at the BMW stand, the automaker will be showing off its Vision EfficientDynamics Concept that's packing a twin-turbo, 2.0-liter four-cylinder diesel that's mated to a hybrid motor. The diesel mill alone is making 204 hp and 295 lb.-ft. of torque, but the addition of a compact generator increases power by another 20 hp and 154 lb.-ft. of torque. Power is sent through an eight-speed gearbox developed by ZF that features longer ratios to make the most of the miserly mill. BMW cites mpg figures in the 43.5-range, with 172 g/km of CO2 being shot on the tailpipe. Additionally, BMW has fitted a regenerative braking system to the X5, along with roof-mounted solar panels and aerodynamically enhanced 19-inch wheels.

All the details are available after the jump in BMW's press release.
