Problem of speed

Hello. My problem is speed rather, the lack of speed in the NFS 2016. I'm starting a career and no car I can not accelerate to the speed which I expected and should be. I throw gear 3, and the car instead of spin up so that I could move up 4 is maintained at all times the speed and does not accelerate .. And what a pleasure to drive when going 80km / h. Please help..
