It is the Los Angeles Auto Show next week and they will be hosting two special guests from Volkswagen. The outrageous GTI Roadster Gran Turismo Concept and the possible-production Golf R400 Concept. The GTI Roadster is powered by a twin-turbo 3.0-litre V6 engine that pushes out a whopping 503 hp and all of this is sent to all four wheels with the 4MOTION system. To really complete the bonkers looks, they fitted massive 20-inch alloy whels and wrapped them in seriously low profile rubber.
