Who is the "Infinite Challenge" cast member that has potential to become an actual racer?

MBC's "Infinite Challenge" held a 'speed racer' special. It's been rumored that there's one cast member who showed exceptional skill as a racer.

The show's staff stated, "There is a cast member who showed superior driving skills and was admired by a current active racer. From the first practice he was noted by the other members, and is currently considered the ace of the group."

The "Infinite Challenge" members declared their participation in the Korea Speed Festival" in May at Songdo. They will be revealing their preparation for the tournament in the March 22nd broadcast.

According to the staff, the cast members showed confidence even up to the point where they got into the car for their first experience. They had previously had some racing experience in 2010 with the 'F-1' special, so they didn't imagine it would be too difficult. However, when they got into the car with an actual racer and witnessed the high speeds, their faces turned pale and one member even had difficulty walking afterwards.

The nervous members worked on circuit training, and battled each other to decrease their times with every round.

The 7 men are each working to become the best racer. The 'speed racer' special will be broadcast on March 22nd.
