well, I did a test once upon a time on an Opel Corsa D 1.1, full weight about 1.3t, and it did reach 139 kph on gps, but.. let's say it if had it in it to go 170, i'd just back off at about 150.

I had no problems going 190-210 on a motorcycle. It's just like boat hull speed, after some limit no matter what you do it just won't go faster.
