I would say that about up to 250 km&#x2F;h car seems to be an expectation based on the manufacturer listed electronically limited maximum speeds for normal German family cars. 2 liter turbo diesel BMW goes up to 240 km&#x2F;h without any problem, but that is not a common German highway speed, I would put it (based on my limited experience) to around 160, up to 180 km&#x2F;h.
