You think you have seen it all but BMW manages to take it to the next step. We must admit, we see some details from their competitor Mercedes Benz in this version of the M4. Always difficult to tell who came first but we think it was that other German manufacturer. Anyway, it doesn’t make this car any less interesting. This is BMW’s M4 GTS concept car that found its debut on Pebble Beach in LA. The 3.0 liter engine in this M4 GTS produces 475 horsepower. This car is made for streetracing, although you probably won’t want to spend 120.000 euros on a car to race with.
