Il y a quelques temps déjà, en début d’année 2016, Porsche en avait étonné plus d’uns : flat-4 is back! L’annonce du Porsche 718 Boxster a été révolutionnaire. Le traditionnel moteur à plat de 6 cylindres fut remplacé par 4 cylindres. Avril 2016, Salon Auto de Pékin / Bejing Motor Show / Auto China 2016 / 2016 Beijing International Automotive Exhibition / 2016 （第十四届）北京国际汽车展览会（Auto China 2016）（以下简称2016北京车展）将于2016年4月25日—5月4日在北京中国国际展览中心新馆和中国国际展览中心老馆同时举行。预计展出面积22万平米。 Bref, Porsche a présenté en ouverture du Salon automobile en Chine le ‘718 Cayman’ de 300 ch et sa version ‘S’ de 350 ch. Commençons une fois n’est pas coutume par s’approcher non pas du design (quasi identique du 718 Boxster) du nouveau Porsche 718 Cayman, mais regardons sous le capot moteur à l’arrière et à l’intérieur under the hood de ce 4 pattes conçu à Stuttgart pour (re)découvrir le flat-4 moderne.
Histoire de flat-4
Mais avant de présenter le stylé Cayman 718 de 2016, regardons dans le rétro afin de (re)découvrir les actualité de l’époque, les modèles historiques, qui ont construit ce que Porsche est devenu. De même, apprécions comme l’actualité récente, actuelle, est un écho permanent aux gloires du passé. Cela va nous permettre de comprendre autant l’histoire du flat-4 que le fonctionnement du 4 pattes de Stuttgart.
1948 – Porsche 356
‘In July 1948, a murmur makes its way through the village of Gmünd in Kärnten. A vehicle drives through the idyllic town in the Alps – a car unlike any other the world had ever seen: stylish and dynamic, sporty, infinitely elegant.’
‘The Porsche 356 glistens in the Austrian summer sunshine: the first vehicle with the official brand name ,Porsche’. Previously, the automotive design office of Ferdinand Porsche had developed all of its vehicles in the name of other manufacturers.’
« La Porsche 356 brille dans un soleil d’été autrichien : le premier véhicule avec le nom de la marque officielle ,Porsche’. Auparavant, le bureau de design automobile de Ferdinand Porsche avait développé tous ses véhicules au nom d’autres fabricants. »
Heritage photo – Porsche Typ 356 Nr1 Roadster – 1948 – Gmund
Ainsi, la Porsche 356 fut la première voiture de la marque allemande Porsche. Conçue par Ferry Porsche sur les bases mécaniques de la Volkswagen Coccinelle et dessinée par Erwin Komenda, elle sera produite en série de 1948 à 1965.
1 086 cm3, 4 cylindres atmosphérique, 40 ch. …jusqu’au modèle 1950. Vitesse maximale : 140 km/h.
Le palmarès en course est impressionnant, et nombre de 356 ont inquiété et parfois battu des voitures plus puissantes, grâce à leur maniabilité et leur légèreté. Elles ont ainsi par exemple remporté le tout premier Championnat d’Europe des rallyes en 1953.
The first Porsche had a four-cylinder engine – and it won over car fans, not only by its charming appearance, but also by its fast-paced character. The very first 356 prototype – production number 1 – raced a fast demonstration lap at the city street race in Innsbruck.
Back then it still had a mid-engine; later in production, it was replaced by a rear-mounted engine. The engine in the 356 is an old acquaintance. It is based on the Volkswagen flat engine that was developed by the Porsche design office in the 1930s.
After Innsbruck, it could no longer be held back. There is hardly a classic race the car has not won: the 24 Hours of Le Mans, the 1000 Kilometres of Buenos Aires, the Mille Miglia, Targa Florio, Carrera Panamericana. The Porsche 356 was always out at the front.
1953 – Porsche 550 Spyder
In 1952, Porsche KG decided to become involved in manufacturer’s racing. The Porsche race car was to be compact, powerful and fast. And above all lightweight to ideally utilise the engine’s power. Engineers went to work – and created the 550 Spyder. Mid-engine construction, ultralight aluminium body, 550 kg unladen weight.
In 1972, the company’s legal form was changed from ,KommanditGesellschaft’ (KG), or limited partnership, to ,AktienGesellschaft’ (AG), or public limited company, because Ferry Porsche came to believe the scale of the company outgrew a ‘family operation’, after learning about Soichiro Honda’s ‘no family members in the company’ policy at Honda.
This led to the establishment of an Executive Board with members from outside the Porsche family, and a Supervisory Board consisting largely of family members. With this change, most family members in the operation of the company including F. A. Porsche and Ferdinand Piëch departed from the company.
And a four-cylinder flat engine that made itself heard quite loudly. Named the Fuhrmann engine after its designer, the engine developed a respectable 110 hp thanks to four camshafts. That was 60 hp more than the first 356 engine just five years prior. It catapulted the Spyder to high speeds of up to 220 km/h.
Its performance at the Targa Florio in 1956 was legendary. At this tradition-rich endurance race in Sicily, Umberto Maglioli and Huschke von Hanstein went to the start in a Porsche 550 A. And they finished victorious – with a full 15 minute lead over even the six- and eight-cylinder competition.

La Porsche 550 Spyder ou 550 Carrera ou 550 RS est une voiture de course et la devancière de la Porsche Boxster. Elle était inspirée de la Porsche 356 Speedster.
Moteur : 4 cylindres à plat opposés à double arbre à cames en tête 1 498 cm3
Puissance : 110 ch à 7 000 tr/min
Transmission : boîte mécanique 4 vitesses
Vitesse maximale : 218 km/h
Poids : 640 kg
La 550 a gagné sa classe dans la course Carrera (Carrera Panamericana) en 1954 avec Hans Herrmann, qui a aussi réussi avec la voiture en catégories lors des Mille Miglia.
Targa Florio 1956 – Historisches Archivfilm Porsche
En 1956, la victoire de la Targa Florio fut très importante pour Porsche grâce à Umberto Maglioli.
« Quant à la Porsche 911 Targa, elle a reçu son nom de baptême en l’honneur des victoires de son constructeur en Sicile. »
- Thierry Le Bras, pilote automobile, écrivain romancier

1957 – Porsche 718
Once again, race engineers accomplished a tremendous task. Despite the visual similarities to its predecessor, the 550 Spyder, the performance data of the Porsche 718 RSK spoke a unique language. At first, 148 hp, and in the 718 RS60 with 1.6 litres of displacement an impressive 160 hp, were teased from the four-cylinder engine.
With an unladen weight of just 530 kg, the 718 also trimmed some significant weight compared to the 550 A Spyder that weighed 550 kg. The mid-engine sports car could now sweep over the asphalt at a maximum speed of 260 km/h.
Thanks to this increase in performance, the Porsche 718 even surpassed the success of its predecessor. At the Targa Florio, the 718 was overall victor in 1959 and 1960; it raced to a class victory in 1958 and 1961, and it was the uninterrupted European Hill Climb Champion from 1958 to 1961. The 718 was also modified into a single-seater and competed in Formula-2 and Formula-1 racing.

La Porsche 718 est une voiture de course du constructeur Porsche, qui débute aux 24 Heures du Mans 1957.
Porsche engine: ‘547/3 F4′ – 1 498 cm3 – 170 hp to 8500tr/min – flat-4
Initialement prévue sous la forme d’une voiture de sport, elle est transformée en monoplace pour participer aux championnats de Formule 1 et Formule 2*
*Formule 2 : …plus tard, remplacée en 1985 par la Formule 3000, elle-même remplacée en 2005 par les GP2 Series, la F2 a connu le retour d’un championnat FIA de 2009 à 2012.
1963 – Porsche 904 Carrera GTS
La Porsche 904 est une voiture de course du constructeur Porsche homologuée pour la route. Elle a été fabriquée en 1964 et 1965 et a aussi connu une carrière en Rallye automobile. La Porsche 904 a été officiellement appelé Porsche Carrera GTS en raison du même problème de droits d’appellation qui a nécessité de renommer le Porsche 901 par Porsche 911.
Heritage photo – Porsche 904 Carrera GTS Le Mans – 1964
An innovation at Porsche: the steel box frame of the Carrera GTS is joined to a body made of polymer. The glass fibre reinforced polyester resin developed by ,BASF’ gives the car body an elementary advantage: lightness. And it made genuine racers out of the stylistically confident rockets designed by Ferdinand Alexander Porsche with their characteristic design.
Not only in motorsport competitions, but also in the hands of individual customers. Demand for the elegant mid-engine sports car was so high that in addition to the 100 units needed for homologation an additional 16 Carrera GTS cars were built.
In 1964, the Carrera GTS achieved a prestigious victory. After 720 high-paced kilometres over dusty streets and through tight bends, after seven hours and ten minutes of wild driving along the coast of Northern Sicily, Antonio Pucci and Colin Davis charged across the finish line in first place at the Targa Florio. Once again, the Fuhrmann engine, Porsche’s proven four-cylinder flat engine put on a display for its class.
The 904’s engine layout was inherited from the 718, also known as the RSK (for ,Rennsport’ or ‘racing’ & ,kurz’ or ‘short’), the factory’s leading race car. It was powered by the 1,966 cc Type 587/3, four-cam flat four-cylinder engine producing 198 hp, « probably the most complex four-cylinder » ever.
It drove a five-speed transmission. Begun as the Type 547, its development began in 1953, when the previous VW-based 1,100 cc flat-four, used in the contemporary 356 and rated at 38 hp, hit the limit of its potential. Porsche realized it needed something all-new.
The brainchild of Dr. Ernst Fuhrmann, later Technical Director, it was hoped to achieve an ‘unheard of’ 70 hp per 1 l,relying on hemispherical combustion chambers (which would be called ‘‘Hemi’ of hemispherical‘ by Chrysler in the U.S. … later under the hood in Dodge HEMI by FCA group) and Weber carburetors to generate 112 hp from the 1,500 cc four-cam engine.
The 1.5 liter produce 180 hp. A complex design that proved ‘very taxing’ to build and assemble, but very durable, it was used in 34 different models, including 550 Spyders, 356 Carreras, and F2/1s.
1976 – Porsche 924
To introduce its new model, Porsche planned a high-speed drive. It optimised a Porsche 924 to set an endurance speed record. The goal was to drive the car a distance of 10,000 miles at an average speed of over 250 km/h. The engineers soup up the standard turbocharged four-cylinder engine to 250 hp, and the aerodynamics of the 924 are further perfected in the wind tunnel. This boosts the top speed of the endurance sports car to 280 km/h.
However, the record attempt would never take place – shortly before the drive planned in July 1977 the project was stopped for strategic reasons.
As a topical response to the oil crisis of the early 1970s, it was decided that the production 924 would be equipped with an efficient four-cylinder in-line engine. For the first time, Porsche also employed a water-cooled front engine in combination with a transaxle gearbox at the rear axle.
In the base version, the compact sports car had a power output of 125 hp, and the S versions up to 160 hp. The turbocharged engine of the 924 Carrera GT even reaches 210 hp and a top speed of 240 km/h.
In successor models to the 924, the 944 and 968, the designers remained true to the combination of an in-line four-cylinder engine and the transaxle concept. The 944 became one of the most successful sports cars of its time – and it saved Porsche AG through the economically turbulent 1980s.
Heritage photo – Porsche 924
La Porsche 924 est une automobile construite de 1976 à 1988. Novatrice sur de nombreux points, cette auto fut un énorme succès commercial pour Porsche.
Volkswagen est dans une conjoncture très précaire, la Coccinelle est sur le déclin. Porsche, de son côté, voit les ventes de la 911 s’émousser peu à peu. C’est donc d’un commun accord que Porsche et Volkswagen, étroitement liés, entament le développement d’un deuxième coupé sportif accessible au grand public, comme c’était déjà le cas avec la Porsche 914.
Les ingénieurs prendront comme modèle la 928 encore en développement. Ils concevront une voiture avec la même architecture inédite ‘Transaxale’, tout en utilisant un maximum de pièces disponibles dans la banque d’organe de VW.
Le design est signé Harm Lagaay.
Harm Lagaay – carrer team design Porsche - ,Ab 1971 arbeitete er in der Design-Abteilung von Porsche in Weissach und wirkte bei der Gestaltung der Modelle 911, 924 und 928 mit. Neben den Studien Porsche Panamericana und Porsche 989 wurden die Serienmodelle Porsche Boxster, Porsche Cayman, Carrera GT, Cayenne und der 911 (Modellreihen 964, 993 und 996) von ihm stilistisch maßgeblich definiert. Der Typ 996 geriet in die Kritik: Lagaay übernahm die Frontpartie des Boxters, und die Scheinwerfer wurden von Fans als « Spiegelei » kritisiert. Mit einem Facelift behob Lagaay diesen Makel wieder. Seine letzte Arbeit war der Porsche 911 der Modellreihe 997, die von 2004 bis 2012 verkauft wurde.’
L’ancienne usine NSU de Neckarsulm (plus tard c’est devenu le QG de quattro, le département Audi Sport) est désignée pour assurer la production.
Le contexte de crise économique et la hausse du coût du carburant, entre autres, poussent Volkswagen à abandonner le projet (EA 425), la firme concentre ses efforts sur des modèles plus populaires comme la Golf. Porsche rachète donc la part des travaux de Volkswagen, et poursuit le développement de son côté. Elle s’attelle à créer une auto d’entrée de gamme de caractère, efficace, confortable et utilisable au quotidien.
C’est la naissance de la gamme des Porsche à moteur avant, gamme qui sera renforcée par la suite par les 928, 944 et 968.
La conception de la 924 est radicalement différente de celle des 911, leurs architectures sont totalement opposées :
Moteur Flat 6 arrière refroidi par air sur les Porsche 911 …jusqu’à la génération dite type ‘993’.
la 924 est dotée d’un 4 en ligne à refroidissement liquide, par eau et en position avant, sous le capot.
Implanté en porte-à-faux arrière dans les 911 et dans les premières Porsche et les Coccinelle, c’est-à-dire en arrière de l’essieu arrière, le groupe propulseur est placé sur l’essieu avant dans les 924/928/944/968.
Cependant la transmission s’effectue via un système portant le nom de Transaxale. L’ensemble boîte de vitesses et pont est positionné au niveau de l’essieu arrière, ce qui donne une répartition des masses favorable.
2016 – ’40 years of the transaxle’
On the one hand, they are ideal sports cars, and on the another an aberration in Porsche history: the transaxle models. The Porsche Museum is showing examples in a special exhibit from April 27 to October 16, 2016.
‘In 1976, Porsche introduced the transaxle powertrain configuration in the type 924 and embarked into new territory. The engine is mounted in front, but the transmission is at the rear axle. Between 1976 and 1995, Porsche built a generation of sports cars that deviated far from the established principles of the 911 – in the types 924, 928, 944 and 968. On the occasion of the 40th anniversary of these models, the Porsche Museum is showing 23 exceptional examples of these cars in the framework of the special exhibition « The Transaxle Era. From the 924 to the 928. » Over half of these cars are being exhibited at the museum for the first time ever.’

‘Transaxle Day’ on May 22
Sunday, May 22, is ‘International Museum Day’, and the Porsche Museum invites visitors to attend its « Transaxle Day ». Along with free admission on that Sunday, many guided tours will be conducted through the special exhibition. In addition, private owners will be showing their transaxle vehicles at various parking places around the museum. Visitors can look them over at the entrance plaza to the museum, in the logistics courtyard and in front of the branch office. A highlight will be the Transaxle Talk at the shop inside the museum, in which time period witnesses who were very involved with the models will offer a retrospective on the development and successes of the 924, 928, 944 and 968 models.
1981 – Porsche 944
In one of the successor models to the 924, the 944, the designers remained true to the combination of an in-line four-cylinder engine and the transaxle concept. In 1981, it closed the gap between the entry-level 924 model and the 911 SC. With 163 hp and a list price of 38,900 DM, the 944 was positioned precisely between the two models.

The centrepiece of the 944 was its newly engineered naturally-aspirated engine with 2.5 litres of displacement. The in-line four-cylinder engine is based on the right cylinder bank of the eight-cylinder engine of the Porsche 928. Thanks to the use of two Lanchester balancer shafts, the 944 engine was smoother running than many six-cylinder engines. Its digital engine electronics and L-Jetronic fuel injection also pointed the way to the future.

Turbocharger
The displacement of the new 718 Boxster and Cayman models has been considerably reduced with the aim of lowering fuel consumption. Nevertheless, the power output of the new engines has been significantly increased. This has been possible thanks to the turbochargers developed for the 718 models completely from scratch.
The respective turbocharger is particularly compact and has been optimally adapted to the displacement and power output of the engine.
The result could not deliver a clearer message. The extraordinarily wide torque plateau makes itself felt with each demand for throttle – barely 30 cm behind your back. And that’s despite a considerable reduction in fuel consumption and emission values. After all, what is performance without intelligence?

Variable turbine geometry (VTG)
The new 718 Boxster S comes equipped with variable turbine geometry (VTG). Adjustable guide vanes on the turbine act to combine the benefits of a small and a large exhaust turbocharger. Derived from the proven 911 Turbo and adapted specifically for the 718 Boxster S, this technology helps to deliver excellent responsiveness at low engine speeds and provide a high maximum power output.

English summary
The new Porsche 718 Cayman
The fourth, redeveloped generation of the mid-engine sport coupé is extending the new model series just a few weeks after the debut of the new 718 Boxster.
The same new four-cylinder flat engines with turbocharging as in the 718 Boxster are being deployed in the 718 Cayman. As a result, coupé and roadster have an identical engine output for the first time. The entry-level version starts with 300 hp from two litres of displacement. The S model delivers 350 hp with a displacement of 2.5 litres. This represents 25 hp more power compared to the predecessor models with an NEDC fuel consumption of 8.1 to 6.9 litres per 100 kilometres.
Even better torque in all engine speed ranges
The tremendous torque of the new engines in the 718 Cayman promises driving fun and agility even at low revs. The two-litre engine of the 718 Cayman achieves a torque of up to 380 Nm (plus 90 Nm), which is available between 1,950 rpm and 4,500 rpm. The 2.5-litre engine of the 718 Cayman S features a turbocharger with variable turbine geometry (VTG), a technology hitherto used exclusively in the 911 Turbo. In the 718 Cayman S, the VTG charger additionally has a wastegate for the first time.
It delivers up to 420 Nm (an extra 50 Nm) to the crankshaft at engine speeds between 1,900 and 4,500 rpm. For the driver this means even better torque in all engine speed ranges. The 718 Cayman with PDK and optional Sport Chrono Package sprints from zero to 100 km/h in 4.7 seconds. The 718 Cayman S completes this sprint in 4.2 seconds. The top speed of the 718 Cayman is 275 km/h, and the 718 Cayman S can reach a speed of 285 km/h.
New chassis tuning for greater precision and more lateral stability
In terms of their driving dynamics, the new 718 Cayman models follow in the tracks of the classic 718 cars. Thanks to their outstanding agility, the historic mid-engine sports cars won numerous races in the 1950s and 1960s such as the Targa Florio and Le Mans.
Lateral rigidity and wheel tracking have been improved in the completely retuned chassis of the 718 Cayman; springs and stabilisers have been designed to be firmer and the tuning of the shock absorbers has been revised. The steering, which has been configured to be ten per cent more direct, enhances agility and driving fun. The rear wheels, which are one-half of an inch wider, in combination with the redeveloped tyres result in an increased lateral force potential and hence in greater cornering stability.
Driving dynamics options such as the Sport Chrono Package and Porsche Torque Vectoring (PTV) allow the sporty character of the 718 Cayman to be further customised. Another available option is PASM with a ten-millimetre lowering of the ride height and additionally in the S model PASM sport suspension with a 20-millimetre lowering of the ride height for the first time. As in the other Porsche sports cars, the Sport Chrono Package can be adjusted via the programme switch on the steering wheel. Supplementing the previous settings of “Normal”, “Sport” and “Sport Plus” is the “Individual” programme, which is able to call up previously programmed individual settings for various systems.
On account of the car’s greater driving performance capabilities, stronger brake systems are now in use with 330-millimetre brake discs in front and 299-millimetre discs at the rear. The 718 Cayman now has the brake system that was previously used in the Cayman S. The 718 Cayman S, on the other hand, uses the four-piston callipers of the 911 Carrera combined with six-millimetre thicker brake discs.
Distinctive design for a more muscular appearance
The new 718 Cayman has been further developed as comprehensively in its design as in its technology. The taut proportions, prominent air intakes at the front and sides and low side profile underscore the boost in dynamics. The nose has a much sharper profile, which gives the front end a wider and more masculine appearance. The ultra-slim front lights above the air intakes, which contain the parking lights and indicators, further reinforce this impression.
Rounding off the front end of the 718 Cayman, are the significantly larger cooling air intakes and bi-xenon headlights in their new design with integrated LED daytime running lights. LED headlights with four-point daytime running lights are available as a new option. Viewed from the side, the new sport coupé reveals its striking wings and side sills. The redesigned rear has a much wider look due to the accent strip in high-gloss black with integrated Porsche badge between the tail lights. The tail lights have been completely redesigned and are distinguished by the three-dimensional technology and four brake spots that appear to float freely.
Redesigned interior and PCM as standard
Inside, revisions are visible for both the 718 Cayman and the 718 Boxster. The upper part of the dash panel including air vents is new. The new sport steering wheel in the 918 Spyder design as well as the extensive connectivity options have now been added to the 718 cockpit along with the Porsche Communication Management (PCM) as a standard feature. Mobile phone preparation, audio interfaces and the 150-watt Sound Package Plus are all part of this standard. Options are available to extend the PCM.
The Connect module, for example, includes special extensions for smartphones, such as the USB port, Apple CarPlay and Porsche Car Connect. Another available option is the navigation module with voice control, which makes it easy to input driving destinations. If the Connect Plus module is selected, this can be extended with real-time traffic information. Drivers can also make use of additional comprehensive services via their smartphone, which include the Porsche Connect App and Porsche Car Connect App.
