The F90 M5 prototype drops more camouflage, revealing the full shape of the headlights and kidney grilles, as well as the shape of the rear tail lights. It also now wears more aggressively styled side skirts and a small trunk lip spoiler. The brake calipers are now painted blue like all steel M brakes.
We expect the F80 M5 to launch approximately a year after the standard G30 5 Series is launched, with an online reveal for the F90 M5 coming in Summer 2017, an auto show debut in Fall 2017 and sales beginning at the end of 2017 - early 2018.
