...Although still covered in a cloth covering, the shapes and lines of the M3 front bumper are now easily seen and there's no mistaking its M6 like design (see the comparison photo below). The middle bumper intake is a trapezoid shape like on the M5/M6, although more aggressively angled. This is flanked by two huge air intakes on each side, which are shaped and angle up aggressively like the M6. There may also be a bit of the 1M bumper style thrown in - at the outer edges of the bumper's side air intakes where air curtain vents appear to be.
