My RS6 made 444 bhp at the crank when it was new (I did not buy it new!), and I had no problem driving it on the street. It is just a question of exercising restraint.
It is the same with the 996 - it is capable of 0-60 faster than I can sneeze, but it doesn't mean I would do it on the way to work. There are far faster bikes out there today, too, driven every day on public roads without incident.
I just think the Brits in the video are making something that is far more authentic in terms of a modern interpretation of the British roadster. They are using a Mazda engine, so don't tell me Mazda can't make an MX-5 with 200 hp. I am not asking for sub-4s 0-60, just something in the low 5s.
