While the M3 was reserved for the four-door sedan version, the coupe was renamed as 4-Series.
Thus, the M version was named M4.

Since the split between the coupe and the sedan/station-wagon version of the 3 Series, the 4-Series took the lead for the coupe versions. That’s how the M4 appeared on the list.

The 4-Series was a shocking appearance when it was introduced in June 2020. The kidney-grille got bigger and now covered the middle side of the front fascia from the bottom of the apron to the hood. It was ginormous! On the sides of the front bumper, BMW installed a pair of vents to cool the brakes. The sculptured door panels and the raked C-pillars resembled the silhouette of the BMW 8-Series. Four exhausts were placed under the rear apron.

Inside, the car was fitted with sport-bucket seats as standard. The instrument cluster featured a TFT color display and, on the center stack, the infotainment system was installed. It featured connectivity via Apple CarPlay and it could support Android phones. If the car was fitted with the automatic gearbox, it was fitted with a pair of paddle-shifters as well.

Under the hood, the M4 surprised its customers with the introduction of the all-wheel-drive system. It was the first M4 that sent its power to all four wheels. The standard gearbox was a six-speed manual. For that, the power went exclusively to the rear wheels. The xDrive version was available only in conjunction with the 8-speed automatic.
