It is way too slow for an A45, 114mph max speed is no where realistic and the acceleration isn’t either. A standard A45 has a top speed of 155mph and an acceleration from 0-60 in 4.2 seconds. So IMHO it is slow
As far as im aware cars speeds and acceleration are dependent on the category of car not on the real stats of a car. This is to help the balance of the server aswell as stopping people flooring it at 220 over a bump and entering orbit as there is no risk to doing that like there would be in reality.
