The achievement is called Race Hero. And you have to win every deathrace in this game.

For this one simply go to your map < races < click on the skull thats there. After about 3 races there is 2 qualifiers. And then 5 races in the final set. Also if you want alot of money bet your max every race considering when you lose you just have to hit retry. Also you do not have to complete the bonus race for this achievement to unlock.

Simply look on your map and travel to the crowned skull. there are about 5-6ish races that you have to win. If you when all of them you get this achievement and you get a crown!
