Speed limits in motor racing
In 2013 a young female water skier was killed in the annual Hawkesbury River Bridge to Bridge ski race. These people get up to incredible speeds on the river.
A coronial enquiry was held and the Coroner's report released late last week. Among the recommendations was that the speed should be limited. One wonders if this could be applied to motor racing in the future? |

It's only a recommendation.

Top speed down Conrod straight hasn't really increased in 20 years, despite all the developments and power increases over that period of time.

Yeah, but 20 years ago.

NASCAR does, in effect, restrict speed by the use of restrictor plates at some of the faster tracks.

This was a "solution" to limiting speeds at Daytona and Talladega implemented in 1988. It should have been temporary but they've not figured anything else out and it's kinda ruined the actually racing at those tracks, imho. It was also used temporarily at New Hampshire, I believe after Kenny Irwin jr. was killed in a practice crash the same year as Adam Petty, but that was actually temporary. |

Speeds are limited in rally as well - stages are designed to keep below a set average speed. We've seen stages amended (Finland I think was fairly recent) to bring speeds down.

Aren't they restricted on Conrod to c.300kph by virtue of a fixed final drive ratio and the rev limit mandated by VASC? Or have I just made that up/imagined that to be the case?

THis is old news. Back in the 1970s, Monza had three chicanes added to reduce speeds. Same for Le Mans in 1990.

I think it's more about putting in a hard limiter, so even if you had the full Mulsanne, you couldn't go past, say, 215 mph; I think it's more that sort of thing.
And those limiters can be tricky; you have to stay ahead of the development of the cars with those, otherwise you run into the problem that, on long straights, you run out of push. You can pull up with the slipstream, but as soon as you pull out, you stall and can't advance any further. Actually, that's kind of what's happened, in effect, with the change to TCR from TC1 in the WTCR. With that ~75-hp cut, the Dottinger Hohe is actually "too long"; they run out of grunt to actually be able to make the pass; that could end up being an issue along the front side of the circuit at Macau as well. |

For whatever technical reason it may specifically be, the fact is the top speed for (V8) supercars has indeed been limited.

So it seems chicanes could be the best way to limit top speed, and the cheapest for competitors.

Track design overall and vehicle specs also contribute to controlling or limiting speeds - as they have done for decades. |
