Kamui is faster as well. He was better than Hirakawa in Super Formula in only his first season, in the same team- Kygnus Sunoco Team LeMans. If he is part of the wec team, that would seriously surprise me. Koby speaks good english which like Nakajima, is key to getting the best out of the team, lineup/driver pairing. There was rumor that Hiroaki Ishiura (Super Formula champ) was left out because he didn't have good english. The team said it was back issues from the high downforce, but that looks questionable seeing as how he's current SF champ and previous SGT champ.
