When the new BMW M3 and M4 arrived I immediately cast my thoughts to how the GTS track car would look. It seems thanks to some spyshots that the development mule has been spotted. The ‘Safety Car’ stickers are just trying to trick you but what does grab my attention are the new aero parts. There is a significantly pronounced chin spoiler and an enticing rear spoiler. If you look carefully enough, you can see that the seats are actually Recaro and not BMW which confirms that this is a racing-orientated car. No word on launch at the moment but let’s hope we get some more spy shots very soon.
