If you are talking about engine performance and how a car can be so great on the road or on the track, the Porsche GT2 RS is one of the sports cars that can deliver that. With 611bhp and a lightweight body, it sprints from 0-62mph in 3.5 seconds, 0-100mph in only 6.8 seconds and 0-124mph in 9.8 seconds. The listed top speed is a conservative 205mph. And all of this is achieved using a regular manual transmission – there’s no twin-clutch PDK option.
