The 2023 model year brought a big change for the 4 Series as all versions transitioned to the iDrive 8 with its dual screens inside a curved piece of glass. In addition, BMW is now installing a small gear selector in all configurations of the 4er except for the M4 as the range topper is sticking with its bulky gear lever. As evidenced in new spy shots, additional changes are planned for the 4er, seen here testing as a coupe.
The prototype photographed without camouflage on the look-at-me kidney grille along with circular exhaust tips is a regular trim level equipped with the M Sport Package. The other two depict a hotter M440i with additional disguise to better conceal the front fascia. It looks as though BMW will better differentiate the M Performance version from the lesser trim. We can already see the front bumper has a more intricate design compared to the current M Lite variant.
