Jesus. Ok. Let me gather myself here...
What in the absolute expletive is going on here. This is a mockery of BMW's motorsports heritage. They took a car which was already too ugly and too large and then slapped more body onto it in all the wrong places, resulting in a Michelin Man of a car. Why is it as tall as an SUV? Why does it have the ground clearance of an SUV? Why is it inflated like a balloon? And they speckled some retro bits and pieces on it, the fences on top the front fenders which aren't actually big enough to get noticed, the aero deflector thing on the roof, the straight rear wing.
If the car itself was proper and actually looked like a BMW was supposed to look then these retro bits would probably be fine - I've seen aftermarket 3.0 CSL retro kits on E30s, E36s, E39s, and E46s and they look really good, because all those cars still look like BMWs. You can connect the dots pretty easily. This car already looked like a Chinese knockoff in and of itself and now it appears to have miserably fat fiberglass overfenders slapped onto it with completely random bulbous shapes. BMW was like, "Wow, Toyota's version of our car is selling like hotcakes, let's make ours just as ugly".
There are a couple good things. The new lights have nice detailing. The new grille is fantastic! Great job on the grille, it's both bold and classy which is key. Nicely shaped, nicely proportioned. The round brake duct air intakes in the front corners are simple and effective, a feature that belongs on a performance car and should've never evolved into the ridiculous gashes that BMW places on their cars these days. Just put a hole in the bumper, everybody loves a nice little hole.
Everything else is terrible.
Edit: And you must be joking with that goofy little shift knob lmao. You're not fooling us BMW, you're a gaudy, overpriced luxury car company now, you can't put a classic utilitarian shift knob in a hideously overstyled and becarboned interior and think we're not gonna notice that you're trying too hard. I see they also realized they forgot to put a Hoffmeister kink on the normal M4 coupe so they slapped some garnish on the 3/4 window as a treat.
Edit 2: Does this thing have side steps like a damn Toyota Sequoia? Wow, full of surprises.
