BMW introduced its 5-series hybrid sedan, which it calls the ActiveHybrid 5, in Tokyo because "Japan is the nation that has made hybrid cars so well known," said company r&d boss Klaus Draeger.
Draeger said it's the most powerful and efficient hybrid in its segment with a 0 to 60 mph time of 5.9 seconds and fuel economy of 40 mpg.
It will be the third gasoline-electric hybrid in the BMW lineup when it goes on sale in Europe and the United States next year.
The ActiveHybrid 5 is powered by a twin-turbo inline six-cylinder gasoline engine and an electric motor that produce a combined 340 hp. The car can drive in electric mode up to 37 mph, Draeger said. The 55-hp electric motor runs off a lithium ion battery.
BMW also markets a gasoline-electric hybrid version of the 7-series sedan and X6 SUV. BMW will add a fourth hybrid late next year: the redesigned 3-series. The ActiveHybrid 3 will use the same gasoline-electric powerplant as the 5 series.
