Four examples of the Porsche RSR 2.1 Turbo were built for the 1974 season, and this particular example is internal number R13, the last of the four built. Campaigned by the Martini Racing Porsche System factory team in four rounds of the 1974 FIA World Championship for Makes, it was driven by Herbert Müller and Gijs van Lennep. Its competition debut was made in June of 1974 at the 24 Hours of LeMans. It was joined by another RSR Turbo, R12, along with a variety of privately entered cars, including three 908s, a 910, and several Carrera RSRs. R12 and R13 were entered in the Group 5 category, and raced against other three-liter sports racing prototypes from Mirage-Ford, Matra, and Ferrari.
During the race, R12 was forced to retire. R13 was in 2nd Place in the early morning until it lost fifth gear resulting it to slow and add 40 seconds to each lap. A short time later, the 1st Place car - a Matra, suffered its own gearbox issues. The problem, however, was quickly resolved by Porsche, which supplied gearboxes to the French team. When the Matra returned to the track, it had lost 45 minutes, which placed it on the same lap as R13. The Porsche still was without its top gear and unable to match the Matra's pace. When the checkered flag fell, R12 was in 2nd Place.
After the race, R13 was sent to contest the 6 Hours of Watkins Glen where it was driven by van Lennep and Müller to a 2nd Place Overall. It then returned to Europe for the remainder of the 1974 season. It placed 7th at Le Castellet in August and a 5th Place at Brands Hatch in September. At the conclusion of the season, Porsche ranked third behind Matra and Mirage-Ford in the World Championship for Makes.
After the 1974 season, R13 was sold to California dealer and race team owner Vasek Polak. In 1977 it was rented to Ted Field's Interscope Racing team for the 24 Hours of Daytona. It arrived at the race with a temporary Fablon wrap covering most of the Martini & Rossi livery and wearing race number 00. Driving duties were entrusted to Danny Ongais, George Follmer, and Ted Field. It qualified in 6th position but after encountering engine problems, it was forced to retire.
Repairs were made and in August of 1977, it was loaned to Follmer for the 3 Hours of Mid-Ohio. Follmer and Howdy Holmes finished 26th overall. It then returned back to California and put into Vasek Polak's private collection. It saw little use over the next two decades. In 1998, it was sold following Mr. Polak's death to Jeff Lewis of Newport Beach, California. After receiving mechanical attention, it was exhibited at the Monterey Historic Automobile Races at Laguna Seca in August 1998, where Porsche was the featured marque.
Mr. Lewis retained the car until 2002, when it was sold to Gregory Galdi of New York. Five years later, it was purchased by John Kotts of Texas. Mr. Kotts treated the car to mechanical attention, including an engine rebuilt. In 2007, it was displayed at Rennsport Reunion III, held at the Daytona International Speedway in Florida. In 2010, it entered the care of its current owner. Since then it has been shown at several events including the Classics at the Castle Porsche Concours to the Amelia Island Concours d'Elegance.
Currently, R5 and R9 are in private collections. The third chassis, R12, has never left Porsche's ownership and is in the marque's museum collection in Stuttgart.By Daniel Vaughan | Apr 2019

At the 1973 Frankfurt Auto Show Porsche unveiled a special 911 concept car with RSR flared fenders, a large rear wing, and the word 'Turbo' on the rear. One month later Porsche announced it would cease factory backed racing in Group 4 for 1974. However in conjunction with Martini & Rossi, Porsche entered a turbocharged Carrera in the Group 5 category.
To comply with Group 5 regulations, a 2.14 liter engine was developed with a magnesium crankcase, polished titanium rods, enlarged oil pumps, dual ignition, mechanical injection and sodium cooled valves. At the rear of the engine was the KKK turbocharger. The package produced more than 500 horsepower.
Continued testing and improvements led to the introduction of the 935 in 1976.
