Tokyo 2011: BMW ActiveHybrid 5 Debuts

BMW pulled the wraps off the hybridized ActiveHybrid 5 at the Tokyo Motor Show today. BMW released details on the ActiveHybrid 5 a few months ago, but the ActiveHybrid 5 display at the Tokyo Motor Show is the first time we’ve seen it in person.

The ActiveHybrid 5 is Bimmer’s first hybrid employing an I-6 as its internal combustion engine; all of its previous hybrids like the recently deceased X6 ActiveHybrid used a twin-turbo V-8. The ActiveHybrid 5 on the other hand is powered by the turbocharged 3.0-liter I-6 from the 535i coupled to an eight-speed automatic transmission, with a 55-hp and 155 lb-ft of torque electric motor sandwiched between the two. Peak power output is 335-hp and 330 lb-ft of torque.

One of the neatest features of the ActiveHybrid 5 displayed here in Tokyo is that its navigation system is linked to the drivetrain, allowing the ECU to power up the battery to help the car get over a steep hill, and then charge it as the 5 Series drives down the hill. Whether this novel system actually works is another story, we’ll find out once the technology actually hits the road.

Fuel economy has yet to be announced but should offer a significant improvement over the 535i’s 21/31 mpg city/highway rating. The BMW ActiveHybrid 5 goes on sale in March. Pricing has yet to be announced.
