One of the toughest obstacles in sim mode is staying under the speedlimit while navigating offroad terrain as quick as possible for nearly an hour in the truck, car and sxs category. This guide shows a method to make staying under the speedlimit a bit easier.
Then just dont shift higher than 4th/5th gear – be careful on downhill sections tho, heading down fullgas can still push the engine over the limit, so step of the throttle from time to time.
Which leads to the car topping out at 130 kph in 4th Gear – 10 kph below the limit, which is a nice cushion.
This made me the only person to have a penalty free run in the truck class as of October 10th in sim mode so far. I might not be fast, but without any penalties – i dont need to be.
So there you have it, I hope this will help you a bit in succeeding out there in the desert – see you on track.
