After years of reporting on mules and showing of spy shots our spy photographers have snapped up images of Volkswagen's new Golf prototype. Our spies spotted the new model undergoing testing in the US. The images shot appear to show two different configurations; a two-door GTI version and what will become the standard four-door hatchback. NEXT GTI: The two-door Golf prototype sports large GTI wheels and twin exhausts. Our spy images show the new model appearing lower and longer than its predecessor. Also snapped up amongst the VW models was Audi’s new prototype A3. The next generation Golf is reported to boast more interior space compared to the outgoing model. The new Golf is expected to be revealed in 2012.Check out our gallery!
