BMW experiments with ‘Power BEV’ test car
BMW has revealed a test vehicle built from a 5 Series production model, showcasing some of its latest electric-car technology.
Named the BMW ‘Power BEV’, the car has had its internal-combustion engine stripped out and replaced with a trio of electric motors.
This results in a total system output of 710bhp and a 0-62mph time of less than three seconds. The battery size and range of the Power BEV haven't been confirmed.
With two independently controlled electric motors on the rear axle, BMW is working on what it has termed ‘e-torque vectoring’, where maximum power can “be translated into forward propulsion even in extremely dynamic driving manoeuvres”.
BMW says this is preferable to a limited-slip differential setup, as the “result is more effective and precise”.
It’s not yet clear how this technology will translate into a future production model, although the manufacturer says the electric motors used in the Power BEV will debut in the forthcoming BMW iX3 SUV.
The iX3 is rumoured to be in line for system output of around 500bhp, although it'll contain only one motor instead of three.
Using its fifth-generation drive units, BMW’s main goal is to explore "what is technically possible" in terms of driving dynamics.
However, in what could be a sign of future manufacturing standards, it says the Power BEV is completely free of rare earth elements.
