why do speedometers go as high as 140 – 160 mph but some average cars can’t go faster than 100 -120?
In: Technology
I believe the speedo is determined by engine rpm, transmission ratio in top gear and diff ratio. with no resistance, the engine at redline in top gear, the rear wheels should be that number.
Not sure how factual that is but my car has multiple different clusters with different red rpm numbers and speeds for different engine packages
