Updated with video from testing at the Nurburgring.
Following on the heels of the
M4 GTS Concept reveal this past weekend at Pebble Beach, the prototype M4 GTS has hit the Nurburgring baring its GTS specific parts.
The GTS prototype now sports the manually adjustable carbon fiber front splitter lip (with Acid Orange accent) and rear trunk wing, along with the M Performance carbon fiber rear diffuser.
The painted carbon fiber hood with heat extractor vent is from the GTS Concept, as well as the lightweight, forged and polished 666M style wheels with Acid Orange accent. The tires are presumably the same Michelin Sport Cup 2 tires (265/35 R19 at the front, 285/30 R20 at the rear) fitted on the GTS Concept.
This prototype is likely testing the new water injection system on an S55 engine which is said to have a "
noticeable increase in output and torque"
The only camouflage remains on the tail lights, which cover new
OLED lights, as already seen on the GTS Concept.
While the GTS Concept did not show its interior, here we see that the prototype is testing with race bucket seats and a roll cage.
Unlike the previous generation E92 M3 GTS which never made its way to North America, the M4 GTS will be available to the North American market.
