The engine do not have enough power to rev up
Please try to set top speed to about 360km/h, then increase a little bit (say 20-30) and have another trail run.
Eventually, you can find the real top speed.
This car have 1030hp, 800Kg only. Why..
jj405the susiki escudo, is not meant or top speed runs, it is a drt trial car, but if you tune it right, you could easily get it to 350km p/h
