According to Car and Driver, Volkswagen head of research and development Heinz-Jakob Neusser confirms that there will be a production version. However, there is no word whether the model is coming to North America. Neusser also claims that the engine in the R 400 is only mildly revised over the Golf R to take the extra boost. There is also the possibility the powerful four-cylinder could make it into other VW Group models.
It's great to hear that the Golf R 400 is more than just a styling exercise. It does a fantastic job at looking understated yet powerful, with the big wheels and bumper but few other body modifications. Now, let's hope VW deems North America worthy of its halo hot hatch.
