The 1961 Porsche RS was one of the last Spyders made by Porsche that used the potent 4-cam engine. It was a successor to the 1960 RS60 which was a highly developed version of the original 550 RS Spyder. These diminutive racecars excelled on the tighter courses like the Targa Florio which was first won by Porsche in 1956. That victory marked the first time a sports car with a midship engine had won a major motor sports event.
Porsche 911 GT3 R Hybrid 2.0 (2011)
The Porsche 997 GT3 R Hybrid 2.0 is an update to the 997 GT3 R Hybrid. Compared to its predecessor, which debuted in 2010, the 2011 second-generation hybrid is 20 percent lighter and more efficient without any concession to lap times. While sharing the same paint scheme, the new vehicle is easily identified by its lack of intakes in front of each rear wheel - changes to engine cooling allowed the slats to be dropped and aerodynamic efficiency improved. It gets a traditional race-bred flat six engine. The GT3 R Hybrid has a completely independent second driveline in the front of the chassis, a clever and complex hybrid electric set up that rockets it from standstill to 60 mph in just 2.5 seconds.
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 919 Hybrid (2017)
According to Porsche, it retained the monocoque from 2016, but 60 to 70% of the 2017 car was new, with the largest alterations being to its aerodynamic demands. This included a major redesign of the front of the 919 Hybrid with wider arches for the front wheels to make it less aerodynamically sensitive from small bits of discarded rubber from the track surface. Porsche remained in the 8 MJ (2.2 kWh) MGU category for the 2017 season. The engine was modified to be lighter and more compact, and Porsche stated that it was its most-efficient ever.
Porsche 908/02 Flunder
The 908/02 K Spyder and 908 K Flunder Spyder were basically the same cars with slightly different bodyworks. If you look at the non-Flunder Spyder, you see that the body drops after the front wheel arch and rises again before the rear wheel arch. In the Flunder version, this concavity doesn't exist. The difference between the two versions was mainly visual, no difference in racing use. The first competition the Flunder was entered, was the Nürburgring 1000 km on June 1, 1969.
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.
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.
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.
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 906 Ollon-Villars (Spyder)
A spider body was fitted, and its inaugural appearance was at the Swiss Ollon-Villars hillclimb where it was met with disappointing results that were clearly to-do with poor testing and rushed development. The Ferrari's easily dominated the event and sent Porsche and their ''Ollon Villars Spyder' back to the drawing-board.
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 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.
The Group 6 Porsche 936 was the successor to the 908/03 and the turbocharged 917. While the 917 had a 5.4-litre flat-12 biturbo engine, the 936 got a 2.1-litre flat-6 single turbo engine. The reason for the 2.1-litre displacement was to fit inside the 3-litre class (turbocharged cars had a coefficient of 1.4). Despite the small capacity, the engine developed more than five hundred horsepower. Imagine such power in a ~700 kg/1540 lb car!
2001 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.
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.
In 1984 Porsche offered a full works-specification car known as the 956B. This provided the New-Man Joest Racing team with a winning formula and they dominated the 1985 24 Hours of Le Mans with a resounding victory. One of the main differences between the customer 956 and the 956B was the Bosch Motronic engine management. This allowed more precise ignition and injection which in turn provided better economy and more power.
The Porsche 997 GT3 Cup was a series of race cars created by Porsche to enter the Fédération Internationale de l’Automobile (FIA) Group GT3 racing class. Replacing the 996 GT3 Cup, the 997 Cup's 3.6 litre engine is rated at 294 kW (400 PS; 394 hp) and was mated to a six-speed sequential transmission. In 2009, the GT3 Cup received several 997.2 updates including a new 3.8 litre engine with an output of 331 kW (450 PS; 444 hp).
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.
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.
The 996 GT3 R was a one-year-only (2000 model year) special of which only 63 were produced. The car took the basic GT3 bones and amplified it for motorsport. The Mezger engine produced over 400 horsepower, while factory-fitted adjustable shock absorbers gave better handling. Most notably, the GT3 R wore carbon-fiber bodywork meant for ultimate light weight in motorsport. The 996 GT3 R was introduced in 1999 as a replacement for the 993 RSR. Before its introduction, it was extensively tested at Weissach and Paul Ricard. In the 2000 FIA GT Championship, the 996 GT3 R was in the N-GT class and won every run. Won the 24-hour race at the Nürburgring. 
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.
The Porsche 956 was a Group C sports-prototype racing car designed by Norbert Singer and built by Porsche in 1982 for the FIA World Sportscar Championship. It was later upgraded to the 956B in 1984. In 1983, driven by Stefan Bellof, this car established a record that would stand for 35 years, lapping the famed 20.832 km (12.93 mi) Nürburgring Nordschleife in 6:11.13 during qualifying for the 1000 km Sports Car race.
The 917 Kurzheck Coupé (917K) first appeared in 1970 and contributed more to the Porsche 917 story than any other variant. It was a high-down force version that featured a cut-off tail for increased downforce. This reduced the cars top speed, as much as 30 mph. Le Mans winner 1970, Interserie winner 1970 and Manufacturers' World Championship for Porsche in 1970.
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.
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.
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.
The 996 GT3 Cup served as the basis for the 996 GT3 road car, featuring a 3.6 litre engine with 355 hp. For the 1999 season the engine output was increased to 365 hp. For the 2001 season the GT3 Cup received modified aerodynamics including an enlarged rear wing and improved cooling. For 2002, the GT3 Cup received several changes, adopting facelift 996.2 features such as Turbo-style headlights. The new body significantly improves aerodynamics and cooling. Engine output was increased to 380 hp. For 20003 onward, the power was hiked once again, with the engine now pumping out 385 bhp @ 7250 rpm and of torque 288 ft lbs @ 6500 rpm.
The third-generation 919 Hybrid (2016 MY) is powered by a turbocharged four-cylinder, two-litre petrol engine delivering almost 500 hp that drives the rear axle. The V4 engine, which is fully load-bearing, is turbocharged and features 4-valves per cylinder, DOHC, a Garrett turbocharger, direct fuel injection and an aluminium cylinder crankcase. In addition, the electric motor delivering more than 400 hp to the front axle. The latter is fed by two energy recovery systems.
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.
Three factory race cars were fitted with a flat eight-cylinder power plant derived from the 1962 804 F1 car, the 225 hp (168 kW) 1,962 cc (119.7 cu in) Type 771, which used 42 mm (1.7 in)-throat downdraft Weber carburetors.  The Type 771s, however, suffered a "disturbing habit" of making their flywheels explode. The 904/8 cars had a short and relatively unlucky racing career.
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.
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.
Porsche 928 Pikes Peak Special
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.
The longer tail 908 Spyders were created only with the Flunder body - the body that's upper surface is almost flat between the axles - and not with the "normal" curvy Spyder body. Very few LH Flunders were created, both with 908/02 and 908/01 chassis numbers. 908 LH Flunder Spyder was first used at the 1969 Le Mans 24h race by Jo Siffert and Brian Redman, but they had to retire because of the gearbox failure. The only excellent result was 3rda at the 1970 Le Mans.
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 908/01 LH Coupé
The FIA’s new three-liter prototype (Group 6) and five-liter sports car (Group 4) regulations adopted for 1968 presented the opportunity for Porsche to update its 907, which had won races but lost the championship. In came a 2997 cc flat-eight engined 908. Despite its aero appearance, it was no easy car to drive fast, weaving as speeds approached 200 mph. Despite winning the 1000km Nürburgring, the 908 was anything but convincing in 1968.
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.
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.
Successful VW Dealer and racer Walter Glöckler built several specials for the German Car Championship including this roadster. It was built with assistance from Porsche in Zuffenhausen and raced without its optional hardtop in the 1952 champion before being shipped overseas for SCCA racing. Weidenhausen created the body from aluminum with a nose that bore close resemblance to the 356 Porsche but had semi-skirted rear wheels and cutaway rear corners similar to Glockler-Porsche 1 and 2.
The Porsche 962 arrived on scene in 1984 as essentially a Porsche 956 for the IMSA/US market. A biturbo version was used in competition racing in Europe, while an IMSA version with a turbocharger featured in North America. The 962 C was based on the 956, with a 120 millimetre longer wheelbase and competed in LeMans. It differed from the IMSA version. The driver trio Stuck/Bell/Holbert was victorious at Le Mans in 1987. Porsche offered the 962 to privateers to race on their own and they were hugely successful.
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.
Based on the road-going 996 911 GT3 RS, the GT3 RSR features improvements to its predecessor in all key areas. The vehicle is available in an ACO (Automobile Club de l'Ouest) version for competing in Le Mans and in the American Le Mans Series as well as in a FIA specification. The 911 GT3 RSR features a modified front which improves downforce at the front axle. The 3.6-litre, six-cylinder boxer engine delivers 445 hp at 8,250 revs. Maximum torque is now 405 Nm at 7,200 rpm, with top revs reached at 8,500 (for the FIA specification with two 30.8 mm air restrictors). Race cars never got more exciting than this.
A handful of push-rod 356As were delivered from the factory with a lightweight package that was usually reserved for the Carrera race cars. Called GTs, these got the stripped out interior, aluminum doors, a large fuel tank and Porsche ATE disc brakes. As few as four Speedsters came equipped this way. Since the four-cam was only a marginal improvement in power, the regular 1600 Super was more than enough for the small car.
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.
The fifth and the last of the 718/2 F2 cars, with chassis number 718/2-05 was an experimental formula racing car. It had the 718/2 chassis, but a different body. The car never got its own type number. It was a one-off car, continuous development project that later evolved into something that became the prototype for the 1961 Porsche 787 F1 car and then even for the 1962 Porsche 804 F1 car. 718/2-05, was first seen at the F2 race on Solitude race track near Stuttgart in July 1960.
As the rules do not permit higher output engines, the engine for the 991 RSR was taken from the 997 GT3 RSR 4.0 and the development work focused on the chassis, body, aerodynamics and the gearbox. A wishbone front suspension replaced the McPherson struts used in 997. A new development was the lightweight gearbox. One of the priorities in the development was the more evenly balanced weight distribution. The centre of gravity was lower, too.
Although Porsche concentrated primarily on development of its twelve cylinder 917 from the middle of 1969, the eight cylinder 908 was also developed further. This 908 received a completely new tubular frame based on that of the 909 Bergspyder and its three liter engine was moved forward by mounting the gearbox ahead of the differential to achieve more equal weight distribution.
Porsche 908K
The Porsche 908/01 K Coupé was basically a 907 K with the new 3-litre flat-8. “K” in the designation stands for Kurz which is “short” in German, meaning the car had short-tail body compared to the 908 LH (“langheck”, long-tail). Although 907 and 908 were similar, there was a visual difference - the 907 had symmetrical front openings and the 908/01 K had asymmetrical. The 908/01 K debuted on May 19 at the Nürburgring 1000 km race and won it outright.
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.
The 1961 4-cylinder special Spyder is the car that became the 1962 8-cylinder W-RS Spyder. It started during the 1961 racing season, when three special 718 racing cars were created for the factory team. Two of those special cars were built as coupés and one as a Spyder - with chassis number 718-047. For the 1962 season, the car got some changes and became known as the Porsche 718/8 W-RS Spyder. Out went the four cylinder and in came an eight-cylinder engine from the Porsche F1 race car (enlarged to 2 liters).
The Porsche 804 was produced by Porsche to compete in Formula One (F1). It raced for a single season in 1962 in the 1½ litre formula. For 1962 Porsche developed an 8-cylinder engine for F1. It was air-cooled and had twin overhead camshafts, four Webber carburetors, and two valves per cylinder. Porsche stayed with carburetors and steel rims while other manufacturers had moved to lightweight wheels and fuel-injection.
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.
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.
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.
During the Geneva Motor Show, a Porsche 911 GT3 R with innovative hybrid drive is making its debut. The innovative hybrid technology featured in the car has been developed especially for racing, standing out significantly in its configuration and components from conventional hybrid systems. In this case, electrical front axle drive with two electric motors developing 60 kW each supplements the 480-bhp four-litre flat-six at the rear of the 911 GT3 R Hybrid. Instead of batteries, an electrical flywheel power generator delivers energy to the electric motors.
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 718 RS 60
For the 1960 season the FIA made changes to the regulation regarding the windscreen and cockpit size. These rules changes together with a larger (1.6-litre) Type 547/3 engine, developing 160 horsepower (120 kW) and a new double wishbone rear suspension brought about the RS 60 model. The RS 60 brought Porsche victory at the 1960 12 Hours of Sebring with a car driven by Hans Herrmann and Olivier Gendebien. 1960 also saw Porsche win the Targa Florio with Hans Herrmann being joined on the winner podium by Jo Bonnier and Graham Hill. z
For the 1969 racing season an absolutely new Porsche 917 with 4.5-litre 12-cylinder engine was created. Ferdinand Piëch relied on the skilfulness of Hans Mezger, who was responsible for the overall construction of the vehicle and its engine. The aim was to create the fastest racing car ever. Short and long tail versions were developed, called as the 917 K ("Kurz" = short in German) and the 917 LH ("Langheck" = long tail). The first car was assembled in December 1968.
