Racing M4 model will be built to GT4 regulations; prototype makes surprise appearance at Munich event
A camouflaged BMW M4 GT4 racing car made an unexpected appearance at BMW Motorsport’s end of year Season Review event in Munich.
This is the first time the car has been seen in complete form – it’s not expected to be revealed properly until development finishes in 2017. Previous GT4 sightings were of a road-going test mule (shown below).
