You still here? Then try goin’ to Engine Setup and then reduce MOI to 0.1. Hopefully that’ll give you your desired result, as that’s what worked out for me. If you’re still not satisfied go to Vehicle Setup and reduce the Mass. If neither of them do it for you, just link and Add Force node to your Throttle event to give an Artificial Boost to your vehicle. But the first one was enough for me, I guess it should work out for you as well
