Duke Dynamics and their design partner Maris Design released a rendering of their upcoming styling package for the BMW 4 Series Gran Coupe. The kit is being developed alongside their wide body M4 package and has the same sort of features.
Shown here in an extravagant chrome turquoise, Duke Dynamics BMW 4 Series Gran Coupe comes with completely revised bumpers, chromed air intakes, larger grilles, an air splitter, kidney grille with horizontal bars, vented bonnet, side skirts, and, presumably, a prominent rear diffuser and tail spoiler.
But the biggest highlight of this kit is the beautifully flared wheel arches, which, combined with a set of properly wide wheels, give the 4er a pretty magnificent look. BMW M cars always look good with flared arches, and this one is no exception.
Duke Dynamics BMW 4 Series Gran Coupe is a strictly visual treatment for now. There might be performance upgrades in the works as well, but details are yet to be released.
