BMW has revealed partial specifications for the BMW i3 fitted with the range-extending engine.

When equipped with the optional range-extender, the BMW i3 will offer a range of up to 186 miles (300 km). This is possible when the batteries are completely charged and the small gas tank is full. Without the range-extender, the car will provide a driving range of between 80 miles (129 km) and 100 miles (161 km) under electric power, making it a viable solution for urban driving.

Various reports are indicating the range-extender will be a two-cylinder gasoline engine taken from BMW's Motorrad (motorcycle) division. We will know for sure next month in Geneva when the car will be presented, along with the i3 Concept Coupe and the i8 Concept Spyder.
