The intriguing BMW M4 GTS prototype recently spied testing has now been snapped hitting the famous Nurburgring for the very first time.

The thing which has caused some debate about this prototype are the MotoGP stickers it is wearing making it appear like the MotoGP safety car. However, the car also features a host of aerodynamic and visual changes and could be an early prototype for a lightweight, M4 GTS variation. For example, it features a revised front bumper and splitter as well as a fixed rear wing. Additionally, the car is sporting a special set of lightweight wheels as well as Recaro racing seats.

As for the existing M4, it is of course powered by the same twin-turbocharged six-cylinder engine as the new M3. This powertrain revs to 7600 rpm and produces an impressive 431 hp between 5390 rpm and 7000 rpm and 406 lb-ft of torque from a low 1800 rpm to 5390rpm. That torque figure is available across a broader rev range and is an improvement over the outgoing BMW E92 M3 of 40 per cent.

As a result of brand new powerplant, both the 2014 BMW M3 and 2014 BMW M4 will sprint to 100 km/h from a standstill in just 4.1 seconds when equipped with the optional seven-speed M double clutch transmission. Top speed is limited to 250 km/h but this can be increased to 280 km/h with the optional M driver’s package.
