The Porsche LMP2000 (also known as the Porsche 9R3) is a Le Mans Prototype racing car that was developed between 1998 and 2000, but never raced. One car was built, and it was designed around a modified version of Porsche's 3.5-litre V10 engine that was originally designed for Formula 1 in 1992. The project was canceled before the car was built, leading to various rumors about the reason for its demise.

Design and development

In 1998 Porsche designed a Le Mans Prototype for the following season, assigning it the codename 9R3.^[2] It was initially to use a modified version of the turbocharged flat-six engine found in the Porsche 911 road car, but, although the design was completed in November 1998, Porsche opted against building the car. Due to the inherent flaws of using the heavy flat-six and the extra cooling the engine would've needed, Porsche instead redeveloped the 3.5-litre V10 engine that was originally developed in 1992 for Formula One, to replace the V12 used by Footwork Arrows; it was redesigned for both 5-litre and 5.5-liter capacities, and the pneumatic valve springs were removed, as the air restrictors mandated under LMP regulations made them redundant. The chassis was unaltered apart from suspension geometry for newer tires and the engine mountings to accommodate the new engine. In May 1999 the project was halted, but the chassis was completed and underwent a two-day private test, driven by Allan McNish and Bob Wollek who reportedly gave positive feedback.^[2]

Despite Porsche's initial denial of the 9R3's existence, rumours circulated about its cancellation, such as the car's engineers were diverted to the Porsche Cayenne SUV project;^[2]^[6]^[7] to avoid competing with its Audi R8 stablemate which won the 2000 24 Hours of Le Mans;^[2] and insufficient competition after the withdrawal of BMW, Toyota, Nissan and Mercedes-Benz.^[1] The engine from the car was used in the Porsche Carrera GT concept car and was retuned for the production version.^[1]

In July 2018, the car was seen in public for the first time at the Goodwood Festival of Speed, as part of the 70th anniversary celebrations of Porsche.^[8]

The Porsche 935 was a race car developed and manufactured by German automaker Porsche. Introduced in 1976 as the factory racing version of the 911 (930) Turbo and prepared for FIA-Group 5 rules, it was an evolution of the Carrera RSR 2.1 turbo prototype, the second place overall finisher in the 1974 24 Hours of Le Mans.

The Porsche 911 GT1 is a car designed and developed by German automobile manufacturer Porsche AG to compete in the GT1 class of sportscar racing, which also required a street-legal version for homologation purposes. The limited-production street-legal version developed as a result was named the 911 GT1 Straßenversion.

The Porsche 917 is a sports prototype race car developed by German manufacturer Porsche to exploit the regulations regarding the construction of 5-litre sports cars. Powered by a Type 912 flat-12 engine which was progressively enlarged from 4.5 to 5.0 litres, the 917 was introduced in 1969 and initially proved unwieldy on the race track but continuous development improved the handling and it went on to dominate sports-car racing in 1970 and 1971. In 1970 it gave Porsche its first overall win at the 24 Hours of Le Mans, a feat it would repeat in 1971. It would be chiefly responsible for Porsche winning the International Championship for Makes in 1970 and 1971. Porsche went on to develop the 917 for Can-Am racing, culminating in the twin-turbocharged 917/30 which was even more dominant in the role. Porsche drivers would win the Can-Am championship in 1972 and 1973. 917 drivers also won the Interserie championship every year from 1969 to 1975.

The Audi R8 is a Le Mans Prototype sports-prototype race car introduced in 2000 for sports car racing as a redevelopment of their Audi R8R and Audi R8C used in 1999.
