Initially, Porsche's involvement in motorsports was limited to supplying relatively small engines to racing underdogs until the late 1960s. However, with models like the 911 Carrera RSR and the Porsche 935 Turbo, Porsche dominated the 1970s. They even surpassed sports prototypes, a category in which Porsche entered successful models such as the 936, 956, and 962.
Porsche is currently the world's largest race car manufacturer. In 2006, Porsche built 195 race cars for various international motor sports events. In 2007, Porsche was expected to construct no fewer than 275 dedicated race cars, including RS Spyder LMP2 prototypes, GT2 spec 911 GT3-RSRs, and 911 GT3 Cup vehicles.
The Porsche 917 is regarded as one of the most iconic racing cars, bringing Porsche its initial 24 Hours of Le Mans victories, while open-top versions triumphed in Can-Am racing. Porsche went on to dominate IMSA GTP in the 1980s with the Porsche 956/962C, a highly successful sports prototype. The Porsche 924/944 platforms also secured class wins at Le Mans.
Porsche achieved unexpected Le Mans wins in 1996 and 1997 with the Porsche WSC-95, raced by the private Joest Racing team. In 1998, Porsche won overall with the Porsche 911 GT1-98. After a period focusing on smaller classes and developing the water-cooled 996 GT3, Porsche returned to top-tier Le Mans racing in 2014 with the Porsche 919 Hybrid. This program secured overall victories at the 24 Hours of Le Mans in 2015, 2016, and 2017, completing a hat trick and achieving Porsche's 19th overall win before the 919 was retired.
In 2021, Porsche announced its return to the FIA World Endurance Championship LMDh category with Penske running their factory team, entering two new Porsche 963 cars in both WEC and IMSA for the 2023 season. The 963 made its FIA World Endurance Championship debut at the 2023 1000 Miles of Sebring. The Porsche 963 took its first victory in IMSA competition on the Streets of Long Beach with Mathieu Jaminet and Nick Tandy driving. In 2024, Porsche won the IMSA SportsCar Manufacturers' Championship, the IMSA SportsCar Grand Touring Prototype Teams' Championship, the IMSA SportsCar Grand Touring Prototype Drivers' Championship, and the FIA World Endurance Hypercar World Endurance Drivers' Championship.
Various versions of the Porsche 911 proved to be strong competitors in rallies. The Porsche works team was occasionally present in rallying from the 1960s to the late 1970s. Porsche achieved three consecutive double wins in the Monte Carlo Rally from 1968 to 1970. In 1970, Porsche also won the International Championship for Manufacturers (IMC), the precursor to the World Rally Championship (WRC). Jean-Pierre Nicolas won the 1978 Monte Carlo Rally with a private 911 SC, and Porsche's second WRC win came at the 1980 Tour de Corse. The Porsche factory team also won the Paris Dakar Rally in 1984 and 1986 using the 911 derived Porsche 959 Group B supercar.
Porsche AG never fully embraced single-seater series. In 1961, former F2 cars were moved up to Formula One, where Porsche's design was not competitive. For 1962, the newly developed Porsche 804 secured Porsche's only win as a constructor in a championship race, claimed by Dan Gurney at the 1962 French Grand Prix. Porsche withdrew from F1 at the end of that season due to high costs.
Porsche returned to Formula One in 1983, supplying water-cooled V6 turbo engines badged as TAG units for the McLaren team. These TAG-Porsche powered cars secured two constructor championships in 1984 and 1985, and three driver crowns from 1984 to 1986. The engines powered McLaren to 25 victories between 1984 and 1987. Porsche made another return to F1 in 1991 as an engine supplier, but with disastrous results, failing to score a single point. In March 2023, Porsche announced that they would not be joining Formula 1 in 2026.
Porsche first attempted to compete in the 1980 Indianapolis 500 with an engine based on the 935 sports car flat 6. Porsche returned to CART in its 1987 season. In 1989, Teo Fabi gave Porsche their only CART victory at the Red Roof Inns 200 at Mid-Ohio Sports Car Course. Porsche withdrew from IndyCar at the end of the 1990 season.
In July 2017, Porsche confirmed their departure from the FIA World Endurance Championship to focus on their Formula E campaign, which began with the 2019–20 season. André Lotterer qualified Porsche's first Formula E pole position at the 2020 Mexico City ePrix. At the 2022 Mexico City ePrix, Pascal Wehrlein claimed his and the team's maiden victory after taking pole position. In the 2023–24 season, Pascal Wehrlein clinched the Formula E Drivers' Championship, and the team finished second in both the Teams' Championship and Manufacturers' Trophy. In the 2024-25 season, Porsche secured both the teams' and manufacturers' championship.
Porsche Carrera Cup is a series of one-make racing, initially with Porsche 911 Carrera Cup cars and later Porsche 911 GT3 Cup cars. The top tier is the Porsche Supercup, established in 1993, which races as part of the FIA Formula 1 World Championship support program. The second tier consists of national Carrera Cups in various countries, with the Porsche Carrera Cup Germany being the longest-running. The third tier is the Porsche GT3 Cup Challenge or Porsche GT3 Cup Trophy, recently renamed in some markets as the Porsche Sprint Challenge.
