Tuomas Koriala is a Finnish simracer. He made his debut in GPVWC in the Challenge Spanish Grand Prix 2012. He wanted to gain experience from the mod so he could compete in 2013 Formula Challenge season. However the testing was quite unnecessary as the mods for 2013 changed dramatically. He surprisingly took the 2nd place in the qualifying, showing that he has the speed needed. However the races itself weren't mindblowing. He did take the lead of the Feature race as a result of David Gaspers' accident, but soon lost the lead as he spun. He kept spinning and when it was time to pit, he hit the wall after braking late in the pit entry. The reason for this unluckiness was that he didn't test the mod enough before the race, thus causing him trouble in the race. He struggled 11th. In the Sprint race he finished 9th. This was because of the collision on T1.
Before his debut, he competed in Formula SimRacing season 2012 in World Trophy, with decent results.
