Mercedes-Benz has dreamed up something no production carmaker has done before — a rear wing where even the endplates come alive. A fresh patent filing describes a clever piece of engineering: extended lower elements, a hinge, an electric motor, and what looks like an ordinary endplate. Folded flat, the whole thing acts as an oversized side wall — separating high and low pressure zones, stopping air from spilling over the edge, sharpening aerodynamic efficiency.
And then it gets interesting. On command, those elements pivot upward — turning into two miniature wings flanking the main element. Downforce spikes almost instantly. Exactly what you want at high speed and on the racetrack, where tenths of a second decide everything.
Mercedes-Benz engineers spell out the problem with race cars in their own filing. Every track demands a different level of downforce — which means either dragging a warehouse of different wings to every event, or fitting a complicated adjustable rig. Huge inventories, massive costs, fiddly install-and-remove cycles, and plenty of room for mounting mistakes. The new idea is supposed to be simpler, cheaper, and remotely controllable.
Will it ever reach a showroom? Big question. But the patent slots neatly into the future of the Mercedes-AMG GT or a CLE 63 Black Series. And for race teams, this kind of wing is a dream — you tune the car for the track with a button, without taking half of it apart.
