This may seem like a regular BMW i4 M50 with an M livery but it's a much more interesting prototype hiding a juicy powertrain. Spotted testing in snowy northern Europe, the EV is a quad-motor monster with the aggressive kidney grille design of the M3 CS and M4 CSL. Gold brake calipers tell us it had carbon-ceramic brakes to match what we can only assume is neck-twisting acceleration delivered by the instant response of the four electric motors.
BMW has already showcased its all-electric M testbed, but without going into any details. However, Frank Weber, Head of Engineering and R&D, told BMWBLOG last year the M division already has the technology for a high-performance EV with as much as one megawatt of power. That works out to 1,341 horsepower or roughly two and a half times more than a standard dual-motor i4 M50.
