When Porsche entered into races, Porsche astonished the world with its performances. But participation in Formula One races brought mixed results. In the 1961-1962 season, Porsche participated as a constructor but produced just one win in a championship race, claimed by Dan Gurney at the 1962 French Grand Prix. In a non-championship race, one week later Stuttgart’s Solitude it repeated the success. At the end of the season, Porsche retired from F1 due to the high costs.
In 1983, Porsche returned to Formula One, supplying engines badged as TAG units for the McLaren Team. It was a success as the Porsche-powered cars won two constructor championships in 1984 and 1985 and three driver crowns in 1984, 1985 and 1986.
Less than ten years later, in 1991, Porsche returned as a engine supplier, but this time the results were disastrous: Footwork, the Porsche-powered cars, didn’t score a single point and at over half of the races it even failed to qualify. Since that year, Porsche has not participated to Formula One.
Still, lightly-modified Porsche’s participate in many competitions around the world, mostly in amateur classes for enthusiasts. The only professional category is the Porsche Michelin Supercup raced as a support category for European Formula One rounds.
