At the start of the challenge or a few seconds after, slow the car to 181 to 183 mph. Do not let the meter at the top of the screen transfer below 24th or you will be out of contention. When you feel that you have enough room between the cars that will wreck and yourself, accelerate. You should have enough speed to get to about 4th place. Stay alert to dodge the wrecking cars. Do not slow if you happen to drive through some smoke. You have to time it correctly in order to catch the lead pack.
