Description
These victories were no accident. Ford made sure of that. The car was specifically, painstakingly designed for endurance, designed for speed…designed to win. Each element of the MKIV was totally different from other GT40s, starting with where it was made. The MKIV was built from scratch in the United States, unlike its predecessors the MKI and ll cars which were built entirely or partly in Europe. A little “skunk works” company called Kar Kraft built the all-new J series chassis and newly designed long, streamlined bodywork for Ford’s Special Vehicles Activity. The MKIV was easily the most radical variant of all the GT40s.
Other modifications were made as well. A NASCAR-style, steel-tube roll cage was added as a direct result of beloved racer Ken Miles’ tragic death while testing the first J Car. Though it was significantly safer, the roll cage was incredibly heavy which hurt the car’s performance.
