A rather easy achievement. Can be done on the first real race in this DLC. When you start the DLC for the first time you will already be racing, but this doesn't count. You have to drive to a race on the map.
On each race you can earn 3 stars. Each star has an individual requirement. To get 3 stars you have to meet all the 3 requirements in 1 race.
It helps if you get used to the snowy underground and know the tracks. So if you don't get it on the frst race just keep racing and you will get better. If everything else fails remember to drill down the difficulty in the options. The requirements remain the same but the opponents are easier to beat.
