While green clearly set the theme of BMW's sustainable mobility presentations, the automaker didn't exactly get ignored. Sharing the stands with the radical Vision EfficientDynamics Concept was the new ActiveHybrid X6, which BMW is positioning as the world's fastest all-wheel-drive hybrid. This more eco-minded version of the mid-size crossover matches its twin-turbocharged 4.4-liter V8 with the Two-Mode Transmission that BMW co-developed with Daimler- Chrysler and GM to create a sophisticated gas-electric system that develops 480 horsepower and 575 lb-ft of torque all while increasing its overall fuel efficiency by some 20 percent over a standard X6. As for its fast index, the ActiveHybrid X6 will sprint from 0-60 mph in under 5.5 seconds, hit 37 mph on electric power alone or top out at 130 multi-mode mph. It goes on sale here late this year. Also vying for its bit of the Frankfurt limelight was the ActiveHybrid 7, a super-efficient rear-drive variation on the 7 Series that uses a slightly different version of the 4.4L/Two-Mode package which substitutes a Lithium-ion (Li-ion) battery pack in place of the more conventional nickel-metal hydride (Ni-MH) chemistry in its X6 counterpart. While it makes only 465 horses and 516 lb-ft of torque, the sedan can make 60 mph in a claimed 4.9 ticks and proceed on to an electronically limited 150 mph. The ActiveHybrid 7 is due to go on sale here in early 2010.
