A few images of the upcoming BMW M4 appeared online in a Belgian website, along with the promise that this concept will be displayed for the first time at the Pebble Beach Concours d'Elegance that starts in a few days. This all still needs confirmation, but the car in the images looks to be the real thing.
Rumors indicate that this car should have around 450PS (444bhp or 331kW) and 500Nm (369lb/ft). It should lose 100kg (221lbs) thanks to the use of carbon fiber reinforced plastic parts, like the i3 and i8.
I believe that today or possibly tomorrow, BMW will officially reveal this new sports car, so don't miss it here.
