Porsche 910 was the evolution of the 906 with Ferdinand Piëch as its main driving force and Hans Mezger as the head engineer. It came before 907, 908 and 909. Compared to the 906, the 910 had 13" Formula 1 wheels with central locking (906 had 15" 5-bolt wheels), more rounded design everywhere and the roof panel was removable. Because of the targa roof, the cool-looking gullwing doors of the 906 had to be forgotten.
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 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.
Developed for endurance sports car racing, the 906 was a street-legal racing car that raced in the FIA's Group 4 class against cars like the Ferrari Dino 206 P. They often won their class behind the much larger prototypes such as the Ford GT40 Mk II and Ferrari 330 P3/4. Based off the same principles as the 904, the 906 used a boxed steel chassis with a fiberglass body that added rigidity to the design. The greatest success of the Porsche Carrera 6 "Standard" was undoubtedly the victory at the Targa Florio 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.
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.
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.
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.
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.
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.
One of the most confused of all Porsche is this DKS or Dreikantschaber. It might appear like a mid-engine RS61 Coupe, but it is a rebodied 356B with a rear-mounted engine. Unlike the earlier 356s, this one featured fared-in driving lights and cut-off greenhouse reminiscent of of the RS61 coupe. Porsche didn't give this new a car a name since it was homologated and considered a Carrera 2 by the FIA. It was nicknamed Dreikantschaber.
The Porsche 904 debuted late in 1963, for the 1964 racing season. Porsche designed the 1965 Porsche 904 Carrera GTS variant to compete in the FIA-GT class at various international racing events and a street-legal version debuted in 1964 in order to comply with FIA’s Group 3 homologation regulations. When the 904 Carrera GTS debuted, it represented Porsche’s first foray into fiberglass bodywork and the last hurrah for its four-cam, four-cylinder engine.
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.
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.
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.
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 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.
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.
While all 356 Carreras are rare and desirable cars, the 1961 B Carrera GT is a very special animal indeed. Built from lightweight materials and sporting Porsche’s most powerful racing engine of the time, they were in a different league to the most highly specified road car that the Stuttgart factory then produced. Porsche produced only 49 of the 356B Carrera versions for 1960/61 and all were coupes. Many were painted Silver.
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.
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.
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.
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
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.
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.
Following the Pre-A prototypes and a run of quad-cams with the 1500cc engine, the 1600 Carrera GT was a performance 356 that used a larger version of the Porsche 550 Spyder's potent engine. As early as 1958, some Carreras were fitted with a larger engine known as the Type 692. The new unit featured a larger displacement which was better suited for the 1600cc class. Furthermore, it was improved considerably adopting plain bearings and new ignition system.
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.
In May of 1957, Porsche offered two distinct versions of the Carrera, one called the de Luxe for the street and this model, the Gran Turismo, for the track. The main difference between the two models was weight. The Carrera GT was a purpose-built car with little on board amenities. For instance, no heater was fitted giving the car its 'icebox' nickname. Furthermore, the interior was stripped of sound deadening, side windows were replaced by pull-up Perspex units and only simple door panels were fitted.
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.
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.
The Porsche 550 Spyder was introduced at the 1953 Paris Auto Show. It was simple, small and packed a real punch. It was Porsche's first production racing car. The car was completely street legal, so it could be driven to the races and back home. A really special engine was developed for it, engineered by Ernst Fuhrmann. It was a flat DOHC engine, meaning it had 4 overhead camshafts like the Porsche type 360 design for Formula 1.
Planned as a successor to the Porsche 550. A one off prototype was the 1956 super-light design utilising one of the spare 550 frames – 550-098 called ‘Mickey Maus’ which, with Richard von Frankenberg at the wheel, was reduced to a melted wreck that same year in a spectacular crash at the Avus race track. Known as Type 645, it was the beginnings of the new Type 718 Porsche with a shorter wheel base and unique suspension.
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.
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.
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.
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.
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 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).
The Porsche 64, also known as the Type 64 and Type 60K10, is considered by many to be the first automobile from what was to become the Porsche company. The first KdF Berlin-Rome competition car, chassis number 38/41, was finished on August 19, 1939. It had a streamlined body and small 4-cylinder aircooled 1100 cc flat engine.
