Owner of the Autopolis circuit Tomonori Tsurumaki ordered 30 Buick powered US built single seater race cars called Sabre FC45 for a race to take place on his circuit's grand opening on November 1990, consisting of a mixture of invited US CART drivers such as Stan Fox, Johnny Rutherford, Dick Simon, Gary and Tony Bettenhausen against local Japanese drivers. The cars were originally built for a spec racing class to have been run by USAC; however, this class was never realized. After the grand opening, Tsurumaki planned on a series with the cars, known as Formula Crane 45. With only a handful of cars during the 1991 and 1992 season the class was not very successful. When Autopolis went bankrupt the assets including the cars were sold to the highest bidder.[1]
