By winning the world championship under every one of the four difficulty settings.
On one of the levels when everyone is making a sort of U-turn there is a sign that that tells you to make a u-turn into that u-turn, don't instead head towards the sign that tells you to turn it should get you a faster lap time and a better positon.
Before you do this make sure the flags rules are off in options. On the 6th turn don't go on the track, cu through the ashphalt, on the 11th corner there is a little short cut, take that shortcut to save 4 seconds per lap. After a couple laps you will be in 1st place.
