The Mercedes C63 AMG reveals the purpose of the Corkscrew. The "Corkscrew" is the most difficult corner of the Laguna Seca racetrack in the United States. It is arguably one of the most difficult corners in the world because of its huge drop and its blind crest and apex on the approach. Many talented drivers met the side barriers in this challenging left / right sequence of turns. Mercedes released this week this clip which shows the Mercedes C63 AMG drift the entire Corkscrew.
