Austrian parts supplier Magna has developed a concept that gives clues about BMW’s new Project i electric car programme.
The lightweight three-door hatchback MILA EV features a removable power module that includes batteries and electric drive motors.
It also incorporates solar cells integrated in the glass roof to provide additional energy generation.
With the high cost of the batteries and electric motor likely to equal or outstrip that of the car carrying it, the MILA’s EV module could become the item that the car buyer owns in future, rather than the bodywork.
Other electric car projects are looking at the battery pack as being an item that the user leases rather than owns.
Magna is working with BMW to explore electric car technology, and hopes other manufacturers will buy its electric platform as an off-the-shelf base for their own vehicles.
