Sadly, the car was relegated to the history books after just a single year of competition. It was undeniably quick, and to date remains the only turbine powered car to win a major race, but it suffered from the same teething issues that most prototype cars face at first. A series of minor mechanical gremlins ended a few races prematurely, while the single gear limited the car's top speed to just under 200 mph—a major disadvantage at some of the longer European tracks.
The team was working on several engineering solutions with an eye toward a seriously successful 1969 when Howmet's marketing team pulled the plug, putting an end to one of the coolest experiments in racing history.
