The BMW M4 has been around for a few years, which means it is ripe for a mid-cycle update. Our spy spotted this M4 Coupé prototype in southern Europe, which reveals a new front fascia as well as revised LED tailights.

Cosmetically the new M4 seems to have taken inspiration from the extreme GTS variant. There is a new front lip that looks very similar to the limited-edition M4’s, as do the twin air intakes on the bonnet. The taillights also seem to have been updated and the spoiler at the back is bigger, too.

The cabin of the prototype was fully disguised, pointing to a comprehensive overhaul of the interior. Several options from the GTS, such as lightweight bucket seats, along with a host of new kit, are also likely to be available on the revised M4.

There is no indication of changes to the powertrain and the newcomer is unlikely to use the water-injection system from the GTS. However, power will possibly go up to 444bhp from the current 414 horses — essentially what you get by speccing the Competition Package on the current M4.

The changes are not specific to the M4 and should be reflected in the entire 4 Series range. The facelifted 4 Series will make its debut next year, followed by the updated M4 that we see here.
