Porsche 935 Tribute (2019)

The 935 tribute car was a non-street-legal collector's car built in a series of 77 cars. It was built from the 911 991.2 GT3 R racing car, fitted with the engine and transmission from the 911 991.2 GT2 RS street car and with the bodykit showing some design details from the 935 cars. The problem: it was not as powerful as the 1978 935 was with even smaller engine and the modern car is much heavier, so the power-to-weight ratio was almost 60% better 40 years earlier.

Porsche 550

Porsche 550A RS Spyder (1956 – 1957)

The 550A was based on Porsche’s first purpose-built racing car, the mid-engined RS 550 Spyder. Appearing at the end of 1956, the 550A differed from its predecessor by use of a full tube spaceframe with several rear supportive cross-members, rather than the heavier welded-up sheet steel internal structure of the 550. The rear swing axles of the 550 were replaced by a new low-pivot arrangement that made handling much more predictable.

Porsche 908

Porsche 908/02 K Spyder (1969 – 1972)

Introduced in 1969, the three-litre 908/2 is an evolution of the Porsche 908K Coupe. As the rule book for the season no longer required a minimum windscreen height nor the requirement to run a spare wheel, Porsche opted for a much lighter Spyder body; which looked like a chopped version of the short-tail Coupe used in 1968. The Spyder body was perfectly suited for high downforce races like the Nürburgring 1000 km and the Targa Florio. It was also about 100 kg lighter than the Coupe.

Porsche Race Cars

Porsche 904 Bergspyder (1965 – 1966)

For the underpinnings of the new 904 Bergspyder, the Porsche engineers recycled five chassis originally laid down for a production version of the six-cylinder 904/6 Coupes. The steel platform chassis of the 904 was reinforced with cross-braces to compensate for the rigidity that had originally been provided by the coupe body. The Bergspyders were tried with both the exotic twin-cam eight-cylinder engine and a highly tuned flat six.

Porsche 356 B

Porsche 356B/1600GS Carrera GTL Abarth (1960 – 1961)

In keeping with FIA regulations, Porsche created a new lightweight 356 with help from Abarth. After Porsche had considered numerous Italian companies to manufacture a lightweight 356 body, they settled on Abarth. Franco Scaglione penned the first initial drawings which attempted to reduce frontal area, overall height. Included was an adjustable scoop on the rear deck lid. Made entirely of aluminum, Abarth's body was smaller than the Reutter 356.

Porsche Race Cars

Porsche 904/6 Carrera GTS (1964 – 1965)

In 1965, the 904’s second and final production year, some examples received a version of the 911’s 2.0-liter flat-six. This version was dubbed the 904/6 and was focused on the factory works effort by Porsche. Six of these cars were so equipped and used a chassis number of 906-0xx. Porsche built a total of six similar 904/6 Works team cars with the following chassis number assignments: 906-001, 002, 005, 006, 011, and 012.

Porsche 924

Porsche 924 Rallye Turbo (1978)

As a top-secret project, the Porsche Museum workshop and the Porsche Heritage department worked on a special front-engined sports car from 1981. 40 years ago, starting on May 15, this car competed in the Deutsche Rallye-Meisterschaft (German Rally Championship). Behind the wheel was non other than Walter Röhrl, with Christian Geistdörfer next to him.

Porsche 911

Porsche 911 GT3 Cup (992) (2022 – Present)

The Porsche Mobil 1 Supercup features the Porsche 911 GT3 Cup, the world’s best-selling race car. For this season, it’s the new generation. 510 hp, optimised intake manifold, electronic gearshift and power steering, fully digital cockpit, larger rear wing, and a double-wishbone front axle. This is a meaningfully upgraded race car. The new 911 GT3 Cup is taking on a great legacy. And it has already proven itself!

Porsche 911

Porsche 911 GT3 RSR (997) (2006 – 2012)

Porsche has announced the introduction of the new 2007 911 GT3 RSR (type 997) for the American Le Mans Series and other world GT racing venues. The latest version of the most successful racing sports car in history is based on the street production model 911 GT3 RS (model year 2007) and was launched in late 2006. The 911 GT3 RSR has wider rear fenders and rear track to improve performance capabilities over its predecessor. The car has also been developed to fit into the 1,225 kg class. The new car is built in accordance with the ACO LMGT2 Regulations and the FIA Article 257.

Model In Depth

Porsche 911 991 GT2 RS Clubsport Race (2018 – 2019)

This car was officially called as the 911 GT2 RS Clubsport, but the name is rather misleading. The car was not built for the GT2 racing class which is long extinct and club sport has stood for Porsche club track days while this non-streel-legal car is a real racing car. Finally, the car was based on the 991 GT2 RS, which already had the Clubsport version. So, in order to understand what is what, we call it "991 GT2 RS Clubsport racing version". The 991 GT2 RS engine with 515 kW was powerful enough, so it was not tuned.

Porsche 917

Porsche 917 ‘Interserie Spyder’ (1969 – 1970)

By 1969, Porsche develops the 917 Spyder with a view to competing in the extremely popular North American racing series, the Canadian American Challenge Cup (Can-Am). Three units featuring 4.5-litre twelve-cylinder naturally aspirated engines are constructed in Zuffenhausen, and Jo Siffert takes one to the US to compete in the Can-Am races, ultimately placing fourth overall. The car becomes known as the 917 PA Spyder, with “PA” standing for “Porsche + Audi” as they are the two sales organisations in the US at the time.

Porsche 356 Pre-A

Porsche 356 SL Gmünd Coupe (1951)

In 1950, eleven remaining Gmund chassis were assembled after the factory returned to Germany and converted to SL (Sport Leicht) racing specification. They received 1,086-cc engines, enlarged fuel tanks, louvered quarter-window covers, wheel spats, streamlined aluminum belly fairings, and a pedestal-mounted shifter. Three Type 356/2 cars raced at Le Mans in 1951; two crashed, but 356/2-063 performed flawlessly, winning the 1,100-cc class.

Porsche 917

Porsche 917 K-71 (1971)

The “shark fins” on the tail gave the Porsche 917 KH 1971 greater directional stability and reduced wind resistance by 11 percent. In 1971 a veritable armada of six Porsche 917s started at Le Mans. The car with start number 22 was special. The white race car with the characteristic Martini stripes had the new “shark fins” on the tail that Porsche had first used in pretraining in April. This 917 was also the first Porsche with a magnesium tubular frame to be used in a race.

Porsche 935

Porsche 935/78 ‘Moby Dick’ (1978)

The 935/78 was the ultimate expression of the 911 factory race car before Porsche officially withdrew from motor sport. Raced under the Group 5 silhouette series, great liberties were taken with the design and the result was nicknamed ‘Moby Dick’ for its large size and huge overhangs. The 935/78 was built under Porsche's Chief Racing by Norbert Singer for high speeds at Le Mans. Due to the advanced shape of the car 227 mph or 366 km/h was possible.

Porsche 934

Porsche 934/5 (1976 – 1977)

In 1967 Porsche prepared a small number of 934 Porsches with 935 Group 5 parts for the Trans-Am and IMSA GTO series. In the end, the 934/5 dominated the Trans-Am series by taking to top five positions in the championship. Ludwig Heimrath became the 1977 Trans-Am champion in his 934/5 by protesting Peter Gregg's highly modified car. Together they humbled the Corvette C3s and the Group 44 Jaguar XJS.

Porsche 911

Porsche 911 Carrera 3.8 RSR (1993 – 1994)

With the 1993 Carrera 2 as the starting point, Porsche had to make at least 50 roadgoing cars in order to qualify this new model for the Carrera ADAC GT Cup, which served as the basis for a motor racing variant to come, the Carrera RSR 3.8. The RSR 3.8 was nothing short of an all-out race car that could be delivered to the track in a ‘just add driver’ form. The Porsche Carrera RSR 3.8 racked up a catalogue of impressive international race results right from the outset, winning overall at the Spa 24 Hours, Suzuka 1000km, and the 24 Hours of Interlagos.

Porsche 911 GT1 Race

Porsche 911 GT1 Evolution (1997)

Towards the end of the 1996 season, Porsche made revisions to the 911 GT1 in preparation for the 1997 season. The front end of the car was revised including new bodywork which featured headlamps that previewed the all-new generation of the (996) Porsche 911 which would be unveiled in 1997. It had the same engine as the previous version, but new aerodynamic elements allowed the 1997 version to be considerably faster than the 1996 version. At Le Mans the works cars led the race but did not last the full distance; a privately entered 1996 specification GT1 managed 5th overall and third in its class.

Porsche Race Cars

Porsche 718 RS 61 LM Coupé (1961)

The story of the 718 coupé began in 1960 when a customer ordered a one-off design from Karosserie Wendler. The car was built on the Porsche 550 chassis. Front-end design came from the 718 Spyder. The roof and the rear end were unique creations by Wendler. For the Le Mans 24h race in June 1961, Porsche created two 718 RS 61 Coupés. They shared the side view silhouette of the Wendler coupé and the rear end of the 718 Spyder, but the front design was original to the car.

Porsche 917

Porsche 917 LH-70 (1970)

With the aerodynamic instability of the 917 in the 1969, two separate configurations were used in 1970. These were the short-tail Kurzheck version and the less common Langheck or long-tail. Most of the 917's accolades were achieved by the 917 Kurzheck, leaving the Langheck a less popular, but ultimately just as potent contender.

Porsche Race Cars

Porsche Formula E – The 99X Electric (2019)

Spark Racing Technology is responsible for a big part of the Porsche 99X Electric. This is the racing car Porsche fielded in Formula E 2019 season. Maximum performance in qualifying mode? 335 horsepower and 174 mph. Zero to 100 kilometers per hour is doable in 2.8 seconds, and the minimum weight including the driver is rated at 900 kilograms of which the battery is responsible for 385 kilograms. In race and attack modes, the output is restricted to 272 and 320 PS, respectively. The useable battery capacity is 52 kWh while maximum recuperation is rated at 250 kW.

Porsche Race Cars

Porsche 787 F1 (1961)

The Porsche 787 is a Formula One (F1) racing car built and raced by Porsche for one year in 1961. The first car (a prototype) was created from the experimental Porsche F2 car with chassis number 718/2-05. The 1961 Porsche 787 was the first Porsche with fuel injection, 6-speed transmission and coil springs in all corners. Only two 787s, serial numbers 78701 and 78702, were ever built. Due to their lack of power and poor handling it was retired.

Gaaco

Gaaco 935L (Porsche 935)

In 1982 Bob Akin Motor Racing commissioned spectacular Porsche 935 to be built for their Le Mans effort. It was built by Chuck Gaa of Gaaco to have a higher topspeed and increased performance. Chuck Gaa fitted a Lola T600 front end to a new bespoke bonded aluminum chassis. According to the regulations, the body retained the 930 roof structure, but was entirely new from the beltline down. The standard 3.2-liter Porsche engine was used and put out 750 bhp.

Kremer

Kremer K4 (Porsche 935)

Using factory 935/78 ‘Moby Dick’ plans, Kremer built their own version. In doing so they modified the body to their own design to include more downforce. Only two cars were built in K4 specification. Bob Wollek drove the first car to win the Porsche Cup in 1981. Later this car was sold to John Fitzpatrick Racing and driven by John Fitzpatrick and David Hobbs to many successes in the IMSA series.

Porsche 911

Porsche 911 R (1967 – 1968)

Based on the 911S, the 911 R was produced by Porsche to compete in the FIA’s GT 2.0 category. To make it competitive, the 911R was powered by a flat-six engine, Type 901/22 from the Porsche 906, capable of 210 hp. It went on a diet too, with weight savings coming from everywhere, getting the 911 R down to just 1,800 pounds dry. Four prototypes were constructed after which Porsche had coachbuilder Karl Baur build another 20 customer cars. In the end, because of the modifications to the 911R, the FIA refused to homologate the car.

Porsche 936

Porsche 936/77 (1977)

In 1977, Porsche returned to Le Mans with the 936/77. Its body was smaller, lower, shorter and further refined aerodynamically. The engine now featured two turbochargers and delivered 20 more horsepower. At one of the most dramatic races in history, Jacky Ickx, Jürgen Barth and Hurley Haywood slayed the armada of four Renault works cars and two factory-supported “Mirage” with Renault motors. In the year 1981, the 936 celebrated a sensational comeback with another overall Le Mans victory.

Porsche 924

Porsche 924 SCCA (924D) (1979)

These cars were designed by the factory to race in SCCA D Production Championship starting in 1979. The Porsche project number of these race cars was 933. Only 16 were built by the factory. However, if you had the right connections, you "could" buy the parts as a kit from Porsche to convert your street car into a fully race-ready 924.

Porsche 356 B

Porsche 356B 1600 Super 90 GT Coupe (1960 – 1961)

Around 20 Super 90 Coupes were ordered with the lightweight GT package for racing. They used aluminum panels, a lightweight interior and plexiglas windows to shed over 200 lbs off the standard production coupe. Inside the car came equipped with a roll bar, leather-strap window lifts and speedster seats. Aluminum exterior panels included the doors, hood, rear deck lid.

Porsche 911 GT1 Race

Porsche 911 GT1 (1996)

In spite of its 911 moniker, the car actually had very little in common with the 911 of the time, only sharing the front and rear headlamps with the production sports car. Designed and developed to compete in the GT1 class of sportscar racing, which also required a street-legal version for homologation purposes. It was powered by a twin-turbo flat 6 that was good for 600 bhp. The 1996 911 GT1 clocked at a top speed of exactly 330 km/h (205 mph) on the legendary Mulsanne Straight.

Porsche 356 B

Porsche 356 B 2000 GS/GT Carrera (1962 – 1963)

As with the earlier versions, the Carrera was offered both in a Carrera GT Deluxe version for the road and the Carrera GT for racetrack duties. Unlike these earlier models, the new car benefited from the 2.0 liter engine introduced as the Carrera 2 was unveiled in September 1962. The 2.0 Carrera used a variant of the Type 547 engine with a larger bore and stoke, having 1966cc.

Porsche Race Cars

Porsche 718 GTR Coupé (1962 – 1963)

The chassis number 718-046 of a 1961 718 RS 61 Coupé was used for a new car called 718 GTR in 1962.. The Coupé version was developed from this RS 61 donor and was initially fitted with a 4-cylinder engine. This car was also upgraded to an 8-cylinder F1 derived engine which produced 210 horsepower (160 kW). The car was also fitted with disc brakes. A GTR Coupé driven Jo Bonnier and Carlo Maria Abate won the 1963 Targa Florio making it three wins at the event for a 718 car.

Porsche 944

Porsche 944 GTP (1981)

In 1981 Porsche developed two 944 prototypes to succeed the 924 GTPs which raced the 1980 24 Hours of Le Mans. To coincide with the release of the 944 in fall of 1981, Porsche prepared a GTP version to promote the car before the launch. The GTP was equipped with a special Type 949 cylinder block with dry sump lubrication, KKK K28 turbocharger and an air-to-air intercooler.

Porsche 911 (997)

Porsche 911 GT3 R (997) (2010 – 2013)

Following the Porsche 911 GT3 Cup, Porsche AG, Stuttgart, is entering yet another racing car in the 2010 motorsport season: The 911 GT3 R will be raced in series based on the international FIA GT3 regulations, thus succeeding the 911 GT3 Cup S. The main focus in developing this new model was on even better drivability and even easier handling. The 911 GT3 R is powered by a four-litre six-cylinder boxer engine delivering maximum output of 480 bhp (353 kW) transmitted to the rear axle by a sequential six-speed dog gearbox.

Porsche 911 (996)

Porsche 911 GT3 RS Race Car (996) (2001 – 2004)

In the 2000 FIA GT Championship, the 996 GT3 R was the dominant racer in the new N-GT class and won every run. In the same year, the factory-supported Phoenix Racing won the 24-hour race at the Nürburgring. In 2001, the modified version, now called the 996 GT3 RS, was used. The vehicle was not only very successful in its class, it also achieved overall victories. Modelled on the 911 GT3 R, the GT3 RS race cars offered a number of technical improvements, which combine to ensure a racing car with optimal competitiveness. 50 racing cars were produced.

Porsche 911

Porsche 911 RSR 4.0 (991.2) (2017 – 2019)

Two decades after the different 911 GT1 cars the mid-engined 911 is back! In order to install a proper diffuser under the rear end of the 991, the engine had to make room for it and the engine/transmission unit was rotated 180 degrees. The extended rear diffuser, a top-suspended rear wing and the new side mirrors help to increase downforce with reduced drag. The FIA rules meant no turbo was needed due to power limits, so the normally aspirated 4-litre flat-6 was taken from the 991 GT3 R.

Porsche Race Cars

Porsche Type 360 Cisitalia (1948 – 1949)

The Cisitalia Grand Prix is a single-seater car for the postwar 1.5-litre supercharged Grand Prix class, built by Italian sports car manufacturer Cisitalia and introduced in 1949. It was designed on behalf of Cisitalia by Porsche between 1946–47, and is therefore also known by its Porsche project number, Typ 360. An extremely advanced design, it proved too complex to build for the small Italian firm (and lead to the financial downfall of the company).

911 Carrera RSR 3.0

Porsche 911 Carrera RSR 3.0 (1974 – 1975)

For the 1974 racing season 911 Carrera RSR 3.0 (246 kW) and RSR Turbo 2.1 (338+ kW) were created - the 3.0L for the customer teams and the 2.1 turbo for Porsche’s own team. The Carrera RSR 3.0 was made in small numbers for racing. The 3.0 RSR would go on to become the most successful Group 4 racing car of its time thanks to its combination of low weight, immense Porsche 917 brakes, impeccable handling, and a 330+hp naturally aspirated flat-6.

Porsche 906

Porsche 906/8 Coupe (1966)

Four factory 906s received an air-cooled eight-cylinder boxer engine of the type 771, which was already used in the 904/8. The engine had a displacement of 2.2 liters with a compression of 10.2: 1 and vertical shafts that drove the two overhead camshafts per cylinder bank. The maximum output was 198 kW (270 hp) at 8600 rpm. All vehicles were equipped with a five-speed manual transmission of the type 906 and a ZF limited-slip differential . The gear ratios could be exchanged as required without removing the gear.

Porsche 924

Porsche 924 Carrera GTR (1981)

The Carrera GTR was the ultimate 924 Street/Race Car in 1981. The GTR had larger flares, larger wheels and tires, improved brakes and a whopping 375 horsepower from the 2.0L turbocharged dry-sump engine. At $75,000, the GTR would have cost over $200,000 in today’s money, but what you got was a 180 mph screamer for the street, but in full race trim.

Porsche 356 Pre-A Model In Depth Porsche 356

Porsche 356 SL Roadster (1951)

When Porsche went to Le Mans, they reverted to aluminum shells made at their first factory in Gmünd, Austria. Three of these coupes, called 356 SL, raced Le Mans. All three Le Mans cars were shipped to America by Max Hoffman and sold to Fritz Kosler, Ed Trego and John von Neumann for SCCA racing. Before the 1952 races at Torrey Pines, von Neumann had Emil Diedt remove the coupe's roof, creating in effect the first Carrera Speedster.

Porsche 917

Porsche 917/30 Spyder (1972 – 1973)

The final evolution of the 917 was created after Ferdinand Piëch had left the Porsche company in 1972. Two complete 917/30 Can-Am cars with 2500 mm (98.4") wheelbase were made for Roger Penske Enterprises racing team. They were chassis 917/30-002 and 003. The 001 car was not a real 917/30 and was raced in Europe at the Interserie. The Can-Am 917/30 had a 5.4-litre flat 12-cylinder twin-turbo engine which produced so much power that nobody really knew how much.

Porsche Race Cars

Porsche 718 RSK Mittellenker (1958)

Porsche created the single-seat 718 RSK Mittellenker (center steering) to compete in Formula 2 racing. The body differed from the 718 2-seat sports racer only to accommodate the central driving position, with revised seat, steering, shifter and pedal placement, and the aerodynamic fairing behind the driver’s head moved from the left to the middle. Instead of having a full-width cockpit, the body sides were extended toward the center to create a space solely for the single driver, with a short, wrap-around windshield.

Porsche 911

Porsche 953 (1984)

The Porsche 953 ranks as one of the finest off-roaders Porsche has ever made. It was basically a souped-up 911 designed specially to give Porsche an advantage in the 1984 Paris–Dakar Rally. Just a year later, it was replaced by the 959. Despite its brief run, it still managed to make quite the impression. Built around a massively enhanced suspension and a supremely powerful 300 bhp (224 kW), 6-cylinder engine, it showed Porsche knew more than just sportscars.

Porsche 911

Porsche 911 RSR 4.2 (991.2) (2019 – 2021)

This was the fourth version of the 991 RSR - the first two came with the rear engine, then the first mid-engine version was launched (all 4.0-litre) and finally the mid-engined RSR 4.2 with the largest 911 engine ever made. The increase in the engine capacity is a question mark as on production models the capacities are decreased and turbochargers are used. The 991 RSR 4.2 didn't have anything in common with the production cars anymore. No change in terms of power-to-weight ratio.

Porsche 718

Porsche 718 RSK Spyder (1957 – 1959)

The 718 was a development of the successful Porsche 550A with improvements made to the body work and suspension. The car's full name is 718 RSK, where "RS" stands for RennSport (sports-racing) and the "K" reflects the shape of the car's revised torsion-bar suspension. It had a mid-engined layout and used the 142 horsepower (106 kW) 1.5-litre Type 547/3 quad-cam engine introduced in the 550A. There were several variations, including the RSK Mittellenker.

Porsche 928

Porsche 928 Pikes Peak Special (2007 – 2009)

In 2007, 2008 and 2009 American racing driver Carl Fausett took his specially prepared and supercharged 1978 Porsche 928 to the Pikes Peak International Hill Climb and competed in the Open Division. Fausett placed third in the Open Division in both 2007 and again in 2009, where he was also the fastest 2WD car. At that time, much of the race course was gravel.
