|BMW 5 Series Hybrid|
BMW estimates the fuel efficiency will increase by 10 percent over the standard model and that it will be slightly more expensive than the conventionally powered sedan. It will also likely have a power advantage over the standard 535i, with the additional electric motor providing aid in the acceleration.
The luxury sedan will come with eight speed transmission and auxillary climate control function. The battery pack is located in the trunk. There is regenerative braking along with an auto start-stop for increased fuel economy. But the two-mode system allows it save fuel while on the highway, too.
Interestingly, the powertrain will interact with the navigation system. That allows it to provide fuel economy feedback according to the planned route.
The 5 Series is scheduled to enter production next year.
