The SLS AMG is a fast car already. No doubt. But like everything with four wheels and an engine, it could be faster. That is where Vath comes in. They’re no rookies when it comes to tuning Mercedes. They’ve worked their black magic on the SLK 55 AMG and C63 AMG as well, turning them up to 565 and 756(!) horsepower, respectively. Now they’ve turned their focus to the newest coach in the AMG stable: The SLS AMG Roadster. If their past cars are anything to go by, we should expect greatness.
