Well if I move the gear selector from D into 3 whilst at 50, the engine revs quite high. I havent tried it at any higher speeds.
I am too not sure about the rpms, as you said the car is built for Europe (it is actually full German spec) therefore you would think that it would be able to do 60 at a lower rpm. Even when I drive it, I always feel that I need an extra gear!
I looked on the speedo for the shift marks, but there are none. Also there is nothing in the speed section of the on dash computer that tells you anything.
Are there any official factory specs for gears and road speed available?
