M4 scores GTS bits

Wild GTS parts due for 2017 base M4

SPY PHOTOS have revealed BMW will update its M4 with juicy bits pinched from the limited-edition GTS.

Seen wearing the GTSís front splitter and bonnet, the mule spied by Autocar hints BMWís not letting the investment made in its fastest ever road car, which uses water injection and produces 368kW, go to waste.

While thereís nothing to suggest the carís mechanical specification will benefit from the same trickle-down effect, a new raised lip-spoiler and re-designed headlights round out the visual tweaks present on the mule.

Expect the facelifted M4 to break cover next year.
