The McLaren F1. That’s almost enough said. But to be clear, with the factory rev limiter in place, this seminal supercar topped out at 231mph around the banked bowl of the Nardo test track. Which means it would go even faster on the flat. With the limiter removed, it reached an entirely verified 243mph – making it one of the few cars here that we can really believe in. Its 618hp V12 also makes it the fastest naturally-aspirated machine on this list.
