It's all teeth and nose.
A couple of months back, BMW M announced that it was officially entering drifting as a works team for the first time. The team it chose to back is the Red Bull Driftbrothers, and we learned that this team would be going sideways in a purpose-built BMW M4. In the first YouTube video announcing the collaboration, we saw a digital render of what the specially adapted Competition might look like, and it was wild. Now, BMW M CEO Markus Flasch has teased the finished design of the vehicle in a series of sketches posted on Instagram. Just take a minute to soak up all the cool little details.
Let's start at the front, where the first design shows a massive front splitter and a front fascia that appears to be a lot airier than the standard one. The fenders have also been widened, as drift cars (rather counterintuitively) need a lot of grip. The wider fenders also help house wheels connected to a steering rack that allows for much greater angles of attack. The other thing that drift cars need a lot more of than you might expect is air. See, if the drifter is doing his or her job correctly, the traditional intakes in the front of the car aren't getting much air. Thus, other designs we see here add a vented hood and a pair of roof scoops. But isn't the M4 front-engined?
Yes, the engine is still in the front, but to help with cooling, drifters tend to mount additional radiators in the otherwise unused trunk. That first video announcing the partnership speaks about some radical innovations the team aims to make in this department, so we look forward to seeing what the design actually turns out like. Other details from some of these designs include a massive rear diffuser free of exhaust tips that are now mounted in the louvered rear window. It's unlikely that this setup is meant to help with aero, but we can see how this would contribute to creating an area of low pressure behind the car. Fortunately, we needn't speculate much as the reveal is set for tomorrow.
