BMW will be offering a two-cylinder motorcycle engine mated to a generator to extend the range of the i3 when it goes on sale later this year.
The package will be available as an option for i3 shoppers looking for more range out of their compact vehicle, although no cost was announced. The full-electric i3 will have a range of 60 to 90 miles on a single charge, while the motorcycle engine can extend that range to about 250 miles on a single tank of gasoline.
Housed in the trunk and connected to a generator that helps recharge the battery, the engine will actually not transmit any mechanical power to the vehicle’s wheels. According to Herbert Diess, BMW’s head of research and development, the motorcycle engine option could be adopted by as much as 50 percent of the i3′s initial buyers. The German automaker believes that it’ll level off at about 20 percent of total orders later on.
