Built so that the factory Rothmans Porsche Rally Team could hit the international stage, the SC RS used the Turbo’s body with fibreglass bumpers and aluminium doors. In Autumn 1983, Porsche presents the 911 SC/RS for motor racing. The engine originates from the 911 SC, with improved performance achieved by the mechanical ball fuel injection, increased compression, the cylinder heads from the 935 and forged pistons. Racing seats are fitted in place of the standard seats.
The technology in racing during the mid 60s was shifting from carburetors to fuel injection. Porsche began experimenting and the Bosch injection system proved to be the most reliable. Though the performance did not increase, it did provide superior throttle response over the Weber carburetors, and it was easier to tune. To compliment the new engine, a new body was created which reduced drag levels. Porsche dubbed the resulting car, with its new engine and body work, the 906E, with the 'E' representing 'Einspritzung, or injection.
Porsche 9R3 “LMP 2000”
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.
Porsche 718 RSK Mittellenker
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.
Because the traditional pre-test is cancelled in 1981, Porsche is forced to start at Le Mans without testing. None the less, the race ends successfully: Jacky Ickx and Derek Bell win almost an hour ahead of the second placed competitor – right in time for the 50th anniversary of Dr. Ing. h.c. F. Porsche AG, and 30 years after Porsche’s first start at Le Mans.
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 2708 Indy
Porsche again attempted to enter CART in 1987. This time it would be a full factory effort, chassis and all. The car had an aluminum-plastic monocoque chassis attached to a 2.6 Liter, 800hp V8. Information gained from their 1980 bid would be used to build the car. This was their first mistake. Indy had stepped up their game over that seven year span. The pole speed at Indy had advanced from 192 mph in 1980 to 215 mph in 1987. It was a different world.
Porsche 911 Cup 3.8 (993) (1994 - 1998)
The 993 Carrera Cup 3.8 was developed from the 993 Carrera RS, as purpose-built competition car designed by Porsche for its single-model racing series taking place around the world. Replacing the 964 Carrera Cup, the 993 Carrera Cup had a claimed 315 bhp on tap, weighed only 1,100kg, and offered a top speed of around 270km/h (170mph). Approximately 216 samples were built. The Carrera Cup should not be confused witth the Carrera RSR, or the 993 Carrera RS Clubsport version.
Röhrl and Geistdörfer very nearly won that San Remo Rally, after a comeback that would have been one for the ages. Röhrl and Geistdörfer were up against a field of faster, more powerful four-wheel-drive cars in their rear-wheel-drive Porsche 911 SC, and somehow managed to pull within an eyelash of victory. Unfortunately, a broken driveshaft forced the pair to retire, leaving Michele Mouton's Audi Quattro to run away with the race.
The pinnacle for hillclimb racing was the mid-1960s and perhaps the most extreme machine of the era was the Porsche 909 Bergspyder. It took weight saving to the extreme. The 909 Bergspyder did not win a major event. It ended up being an awesome laboratory of ideas (not all worked). The 909 Bergspyder was based on the 910, but Piëch had tasked his team of engineers, including the legendary Peter Falk, to remove weight on every component.
The Porsche 961 was the racing version of the 959 supercar. While the 959 rallye car was also internally called 961, publicly only the circuit racer was called 961. Only one 961 was built. It had 959 prototype chassis number which in turn was from the 1985 911 Turbo chassis number sequence: WP0ZZZ93ZFS010016. The 961 was entered at the 1986 Le Mans 24 hour race. Uncommonly, the 24 hour race was scheduled for May 31-June 1 that year, two weeks earlier of the typical Le Mans weekend in the middle of June.
Following a development year with Penske Motorsports in ALMS, Porsche revealed the final version of their LMP2 contender for the 2007 season. Known as the 'EVO' model, it had a host of upgrades that made it suitable for customer-funded teams to successfully compete. This model dominated the P2 class at events like Le Mans and Sebring. It raced from 2007 till 2010 with strong results across the board.
One year before Porsche started production of the legendary RS Spyder, they experimented several unique 550 Prototypes. Two of these were fitted with removable hardtops that transformed the diminutive roadster into a sleek coupe. These were quite successful on faster circuits, but the roadster was later preferred as a more saleable car. The Coupes were retained by the factory to contest the Carrera Panamericana race.
Porsche 904 Bergspyder
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.
The Porsche RS Spyder, internally called 9R6, exists only thanks to a customer order made in 2004 by Penske Motorsports, a subsidiary of Penske Racing. The 9R6 was built according to the Le Mans Prototype class 2 (LM P2) regulations and to be raced at the American Le Mans Series (ALMS) in USA and Canada. The ALMS was created in the spirit of the Le Mans endurance races, hence the name of the series.
In 1967, Porsche brought a new kind of car to Le Mans. The 907 had a small flat-six and incredibly low bodywork, was aerodynamically optimized. Ford won Le Mans, but the 907 proved its worth. At the end of March, 1968, Porsche had four type 907 chassis ready, and brought them to the 24 Hours of Daytona. Fully developed, the 907 now used a 2195 cc aircooled, magnesium alloy flat-eight with Bosch fuel injection, good for 278 bhp at 8700 rpm. The 907LH (lang heck, or long tail) was slippery, stonking fast and wicked hard to drive. And it won.
In 1978, the works team fields two 911 SC at the East African Safari Rally. The name of game is to survive 5,000 kilometres of the toughest tracks in sweltering heat and torrential rain. The conditions take their toll: of the 72 starters, 13 reach the finish line. Martini Racing Porsche System Engineering signs on two specialists to drive: Sweden’s Björn Waldegård (Start No. 5) and Kenyan Vic Preston Jnr (Start No. 14).
Although the longtail 917 was introduced first, it was meant only for the Le Mans. This meant, the short tail 917 K ("Kurz" in German for short) was raced first. The only engine available in 1969 was the 4.5-litre flat 12. The factory team enters one 917 K also for the Nürburgring 1000 km race, where it scores 8th. The factory team would not enter 917 K for racing anymore in the season, only private teams will.
porsche 934
Using the 930 Turbo as a basis, Porsche built the 934 for Group 4 GT racing. It replaced the outgoing Carrera RSR while winning GT Championships in Europe and performing very well in America for Trans Am. Porsche built the 934 from a standard 930 bodyshell and production rear spoiler, but almost nothing else was left alone. The suspension was converted to solid mounts and nylon bushings with adjustable anti-roll bars.
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.
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.
With the car retiring after the 2017 LMP WEC season, the Porsche team decided to throw it a truly memorable send-off. Freed from any restrictions brought upon by strict regulations in the class it competed in, Porsche threw out the rulebook and established a new benchmark. Amongst the notable parting gifts was a significant horsepower bump, increasing the turbo V4 to 720 horsepower from 500 horsepower. Additionally, the electric motor received a 10% boost, now generating 440 horsepower. In total this gave the 919 a remarkable 1160 horsepower.
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 935/77 (1977)
The 935/77 was a result of relaxed rules and the car got a completely new suspension. The mirrors were incorporated into the front fenders and the rear window had a new angle. The 935/77 was visually very pleasing. While the 935/76 had a single turbocharger, the 2.85-litre engine of the 935/77 had two turbochargers. There was also a "baby" 935/77 built with a smaller 1.4-litre turbocharged engine to compete in the national German DRM series under 2 liter class.
In 1967 and 1968, the Porsche 910/8 Bergspyder was the dominant force before the 909 came along. Porsche’s 910 was essentially an updated 906 and were championship-winning machines thanks to being extremely nimble and well-suited to mountain roads. It had titanium (brake calipers), beryllium (brake discs), magnesium (wheels), electron (tank), plastic (body) and aluminium. The running gear was similar to that of a Formula 1 car, including an eight-cylinder boxer engine.
The racing sportscar is prepared by Porsche following the Le Mans GT2 regulations for the over 1,150 kg weight classification. It features a 3.6-litre engine with two turbo-chargers (KKK 24 with 33.8 mm restrictors), which delivers around 450 hp at 5,750 rpm. Even this racing vehicle, with its suspension featuring a McPherson front axle and Porsche multi-link rear axle with LSA system, closely resembles its production relative. Utilizing a steel 993 Twin Turbo chassis with modifications for racing, scored numerous victories in a wide variety of racing venues.
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.
In 1983 Porsche produced a stunning one-of road car for TAG owner Mansour Ojjeh. Based on a 934 chassis, it was designed to mimic the potent 935 racecars and subsequently became the one of the first slantnoses. Both the front and rear sections were made similar to the potent 935 race car which dominated the Group 5 Championship. This silhouette series allowed radical modifications which contributed to the repositioned nose, ultra-wdie flares and extended rear bodywork.
The 959 took both first and second place in the 1986 Paris-Dakar rally. For 1986, the Dakar Porsches finally got all the upgrades from the 959 project, including the active four-wheel drive system offering four driving modes adjusted by the computers. This gave Porsche a 1-2 finish, with supporting 959 Dakar engineer Unger Kussmaul crossing the line at sixth. Once the champagne had dried up, Porsche deemed its Dakar program accomplished.
Porsche 917/10 Turbo
The first turbo-Porsche, Can-Am winner 1972, Interserie winner 1972, 1973. The first ever publically seen turbocharged Porsche was the 917/10 Turbo with chassis number 917/10-011. It was entered for the June 11, 1972 Can-Am Mosport race. Mark Donohue was fastest in the qualification with it, but scored second in the 80 laps race after the 8.1-litre McLaren. The Porsche Turbo era had begun. Eight 917/10 were racing in 1972 in Can-Am and in Interserie.
The 917/20 Turbo is a confusing car - its chassis number reads 917/30-001, but it is not the real 917/30. In its first race it was called as the 917/10 Turbo. Sharp eye can detect that it was not just the 917/10 Turbo, but an evolution of it. At the same time it was not the evolution of the 1971 Le Mans 917/20. Still, the car should not be called as the 917/30 to distinct it from the "real" 917/30 Can-Am racers and in 1974 it was decided to call it as the 917/20 Turbo.
Porsche 718/2 F2
In 1959 Porsche unveiled the prototype of a narrow, open-wheeled car called the Porsche 718/2 that married the 718's mechanicals with a more traditional single-seat Formula body. For 1960 the production 718/2, starting with chassis number 718201, received revised bodywork, a 6-speed transaxle, and a wheelbase extended by 100 mm. A total of five cars were built. Some of these four-cylinder cars were later raced in F1 under the 1962 1½ litre formula.
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.
The Porsche 904 Story & History
Porsche’s Type 904, officially called the Carrera GTS because Porsche and Peugeot were in dispute over numeric designations with “0” in them, succeeded the RSK Type 718 as the last sports-racing iteration of the 356 series. Developed after Porsche left Formula One in 1962, the 904 (as it soon became popularly known) was also the last full-competition Porsche that could be readily driven on the street. This is the full story.
For the 1978 Le Mans, Porsche created two new 936/78. The first one was built using chassis 936-001, which had already served for the 936/76 and 936/77. The second car was built on a new chassis and numbered 936-003. Because of the new water-cooled 24-valve engine, the 936/78 came with huge NACA ducts on the sides for the radiators and a new rear end with hanging spoiler.
In 1953 Porsche created a series of 550 prototypes and 550-03 became the most important car in Porsche history by winning the 1954 Carrera Panamerica with Hans Herrmann at the wheel. This singular victory lent the Carrera nameplate to future models and also marked the first international victory of a mid-engine car. Only 15 prototypes were made until regular production began in 1954 of the Porsche RS Spyder.
Jo Siffert was the first to take the 917 to Can-Am championship. The car he used in 1969, was the 917 PA Spyder. Although he participated in one Can-Am race in 1970 with a 917 K, that season he skipped. He was back from mid-season 1971 and now with the 917/10. Only two 917/10 were created in 1971. The chassis 001 was used for testing and the 002 by Siffert. He took part in six races out of ten, managed podium finishes three times and scored 4th in the season, like in 1969.
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 907 K
The K in 907K stands for short-tail ("Kurz" in German). Porsche brought four new 907s with short-tail bodies to the rugged Sebring circuit in March 1968. Seven laps in, one 907 was out, and a second suffered engine troubles after 46 circuits. Not to worry, as the other two dominated the race. Porsche 907 024 with drivers Hans Herrmann (Germany) and Jo Siffert (Switzerland) went from the pole position to a dominating victory at an average speed of 102.512 mph, 10 laps ahead of its sister 907.
On 3 January 2019 the 718 Cayman GT4 Clubsport was unveiled in two variants, Competition and Trackday, with first customer cars delivered to customer teams ahead of the 2019 Roar Before the Rolex 24 Hours at Daytona International Speedway. The race car is powered by a 3.8-litre naturally-aspirated flat-six engine producing 425 PS (419 bhp; 313 kW) at 7,500 rpm and 425 N⋅m (313 lb⋅ft) at 6,600 rpm connected to a 6-speed PDK gearbox. The kerb weight is 1,320 kg (2,910 lb). Both variants feature a welded-in roll cage, a six-point harness and race bucket seat, a selection of body parts made of natural-fibre composite materials and race suspension from the 911 GT3 Cup.
The 906 LH was capable of achieving 174 mph/280 km/h with its 2-litre engine (906 K: 165 mph/265 km/h). At high speed the long tail started to create lift (opposite to downforce), which made the car go fast on the straight, but was dangerous to drive. At Le Mans, the 906 LHs with their experimental bodies competed in the 2-litre prototype class.
