Yesterday I drove over the AB with my friend and crossed the pedal. Then I looked at the speedometer and was amazed ( but not positive ) I had only about 155 km/h as a maximum speed. And that with an empty car, can one explain to me??? I have only a 60 Ps car, but according to the speedometer I always had almost 190 km/h, if I have crossed ( according to the speedometer ) and now is at 155 km/h end ??? that can not be. Problem: the W Agen still has the same tire ( no winter rubbers ), the consumption has not increased, the engine does not jerk or runs somehow round also I can notice no difference in the acceleration. Except for a smallness: ( I noticed in the traffic jam ) If I have the 1st course and let it roll in idle, then the engine hoops something ( I know so far only of cars which already have some tkm on it ). Does someone have an idea why the engine at 155 km/h at the end by the way I had 155 km/h almost 4500 rpm, otherwise I always came on a straight track up to approx. 5500- 5600 rpm
