How to unlock the First on the GRID achievement in DiRT 4 - Definitive Guide
You can only get this trophy while playing in the FIA World Rallycross championship, so you will need to unlock it first. Please see the related trophy for more information on how to unlock it.
The reason you can't get the trophy before is that in the other events you will always start in the semi-finals, so you won't have the opportunity to set a qualifying time. Once you're in the last championship, you will have 4 qualifying races, the semi-final and the final. What you need to do is to win the first 4 races and set the best time as you can to earn enough points to be at the 1st position at the end of the qualifying races, and earn your trophy.
