why do they limit top speeds of cars?

Question

like its weird. on the sl 65 amg, they limit it to 155 when it could probably go 230 and they limit the m5 to 155. is the some sort of tax on these cars if tehy go over or they too scared some idiot will think its a normal car and kill them selves

Answer 1

Actually it is the maxium speed of the tires. Heat build up at speeds of over 150 mph require special tires. Bugatti can make over 230 miles an hour. It comes equipt with tires that cost $1,200 each. When a tire blows out due to overheating "think nascar" it shreads brake lines and wraps around the suspension. This can be really bad at speed with out the protection of roll cages helmets and racing seats. Insurance companies might also not insure a car that can run 200+

Answer 2

1. Insurance reasons
2. z rated tires are needed for speeds over 150.
3. Roads other than the autobhan or the Desert of Nevada are designed for that speed. Most Hwys are designed for 60-70MPH. When the curve sign says 25, it means that for a reason.
4. Hi performance cars & low perfomance drivers. While James Dean was a great driver, the guy in the Ford he hit was not......

Answer 3

this is a no brainer people that look at the speadometer and say wow this car is fast it willl do 160..... with the congestion on todays roads you tell me were your going to attempt it...I think its all show.. it sells cars ...its status.. the car still has to stay on the road and the manufacturer knows that ..so restrict the cars spead thru the rear gear ratio and let the owner pin himself to the seat 0 to 100 he gets out saying wow that was enough for me now hes scared of it and doesnt need to go any faster

Answer 4

My reasoning is so the police can still catch perps, thou there does exist the odd car that has no governor, either way the highways aren't built for that kind of speed and you'd lose control, so safety.

But yes, I find it annoying.

Answer 5

SO they dont blow up
