BMW is claiming an impressive drag coefficient of 0.24, largely due to a sealed underbody tray. Also, the 4 Series' chipmunk cheek intakes below the headlights actually flow air to intercoolers, whereas the I4's are simply smooth, air-cheating plastic. Also of course, the 4 Series Gran Coupe's grille is an actual grille that lets air flow onto a radiator, whereas the i4's kidneys are in fact a clever, brand identifying way to package radar sensors. The easiest way to tell from the front is that the 4 Series has a thick, chrome trim piece surrounding the massive double kidney grille, whereas the M50's is blacked out. However, you'd have to be a massive BMW nerd to spot the differences between the gas-powered 4 Series and the i4 M50. If you know what you're looking at, this EV screams 4 Series, specifically the G26 Gran Coupe. The i4 M50 is instantly recognizable as a BMW. It's notable that the single motor eDrive40 is closer to 45/55. The M50 achieves a 48.2/51.8-percent front to rear weight distribution. As in the iX electric SUV, the front unit is slightly smaller, lighter, and less powerful than the rear. Each motor is married to a single-speed transmission and power inverter at BMW's sprawling Dingolfing factory, forming a single power unit. The synchronous motors are the fifth generation of BMW's eDrive units. Due to the batteries living under the floor, the center of gravity is 1.5 inches lower than a normal G26's. The G26 has a 1.0-inch wider front track, and a 0.5-inch wider rear track than the standard G20, with increased negative camber on the front wheels. Active dampers come with the M50, not so on the eDrive40.

That means struts up front, plus rear air springs mounted within a five-link geometry.

The i4 uses the current G26 4 Series Gran Coupe iteration of the CLAR platform (the regular, seventh-generation four-door 3 Series is internally known as G20).
