I didn't follow Blancpain when it started, For years I never paid attention to Ratel's low cost GT3 cars. So I have no idea what is meant when a series like PWC or Blancpain{What the heck IS a Blancpain btw} that have Sprint or SprintX races. What is the definition of a SprintX vs Sprint style of race? And, have missed any other types?
Google says... http://world-challenge.com/latest/s...-releases-regulations-racing-format-schedule/ There are 3 paragraphs in the middle which briefly describe the SprintX, Sprint, and Touring Car formats for 2018.
Thanks Bernd, it just seemed to my American eyes that the word was made up. lol. And Lazza, that is fairly simple. Thanks for the link.
