This 5 Series is hiding a massive amount of power underneath that stock exterior. The company has been testing a vehicle they're calling the "Power BEV," which is a 5 Series sedan that hides three of their fifth-generation electric drive units that combine to deliver a massive 720 hp and a 0-62 time of under three seconds. This is quicker and more powerful than the current M5, which produces 600 hp from its 4.4L V8 and a 0-60 time of 3.2 seconds. There's no word on where a powertrain of this type will end up, but a version of it with a single electric motor will arrive in the upcoming iX3 electric SUV.
