The Penske PC4 was a Formula One car designed by Jeff Ferris and used by Team Penske during the 1976. The car was driven to victory in that year’s Austrian Grand Prix by John Watson. German industrialist Günter Schmid brought the Penske PC4 chassis for his newly formed ATS Racing team, set up to participate in the 1977 Formula One season. The team initially fielded a single entry for Jean-Pierre Jarier. He scored a point for sixth place in the team’s debut race in the United States. ATS expanded to two entries later in the season. German Hans Heyer, toiuring cars and Le Mans driver, joined the team for the German Grand Prix. With little experience in single seaters, he did not qualify. He was the third reserve, meaning that he would get the chance to race if three drivers dropped out; however, Heyer chose to start the race anyway, slipping out of the pits and joining the pack without the officials realising. Only when his gearbox failed after 10 laps was it realised that Heyer should not have been competing, whereupon he was disqualified. He never attempted another race in a single-seat car. He is the only driver to be credited with a DNQ (Did Not Qualify), DNF (Did Not Finish), and DSQ (Disqualified) in the same race, earning himself a lifetime ban from Formula One in the process.
