I used the below settings and got this achievement first try
- Select Quick Play (Press RB to see that option)
- Select Chile
- Select El Puma Reverse (last one on the right)
- Select WRC (Team doesn't matter and crew doesn't matter)
- Go to Options > Gameplay settings
- Set Damage Effects to Realistic
- Start the rally
Just floor it and aim for the trees on the bend and you should damage your car beyond repair.
