You don’t need a lot of power to be really fast. This custom Fiat 500 owned by Roman Gurschler proves that. Roman built it to compete in slalom (autocross), circuit, and hill climb racing. Behind the drive sits a 1000 cc inline-four taken from a BMW S1000RR motorcycle that produces 199 horsepower. The power goes through a six-speed transmission to a custom AWD system built by Ronny. Add four racing slicks and you have yourself a very fast vehicle. You can watch more videos of the car racing on his Youtube channel.
