Porsche 911 GT3 R Hybrid

A Porsche 911 GT3 R Hybrid with innovative hybrid drive will be unveiled at the 2010 Geneva Motor Show, taking the evolution of the iconic sports coupe to new levels in motor sport and opening a new chapter in an illustrious racing record that has witnessed more than 20,000 victories in 45 years.

After its debut in Switzerland, the Porsche 911 GT3 R Hybrid will be tested in long-distance races around the Nürburgring, Germany. The highlight of this test programme will be the 24 Hours race around the 14-mile Nürburgring Nordschleife circuit on 15/16 May 2010. However, the focus is not on the Porsche 911 GT3 R Hybrid winning the race but rather serving as a spearhead for the technology and a 'racing laboratory' that will provide invaluable knowledge and insight on the subsequent use of hybrid technology in road-going Porsche sports cars.

110 years since Ferdinand Porsche - the company's founder - developed the world's first car with hybrid drive, the Lohner Porsche Semper Vivus, it is entirely appropriate that Porsche is once again employing this visionary drive concept in a production car-based GT racing programme.

The hybrid technology featured in the Porsche 911 GT3 R Hybrid has been developed especially for racing, and is set apart from conventional hybrid systems in its configuration and choice of components. Uniquely, an electrical front axle drive with two electric motors each developing 60 kW supplements the familiar 480 hp (353 kW) four-litre flat-six 'boxer' petrol engine at the rear of the Porsche 911 GT3 R Hybrid. Consequently, the Porsche 911 GT3 R Hybrid has four driven wheels, offering even greater traction and agility.

A further significant point is that instead of the usual batteries of a conventional hybrid-powered road car, this 911 features an electric flywheel power generator - mounted inside the cockpit beside the driver - that delivers energy to the electric motors on the front axle.

The flywheel generator itself is an electric motor - with its rotor capable of spinning at speeds of up to 40,000 rpm - and stores energy mechanically as rotation, or kinetic, energy. The flywheel generator is charged-up whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators.

The driver is able to call upon this extra energy from the charged flywheel generator at his command for competitive advantage, such as when accelerating out of a bend or overtaking. The flywheel generator is slowed down electromagnetically in the generator mode and able to supply up to 120 kW to the two electric motors at the front axle from its resource of kinetic energy. This additional power is available to the driver after each charge process for approximately 6 - 8 seconds.

Energy formerly converted into heat, and thus wasted, upon every application of the brakes is now converted highly efficiently into additional drive power.

Depending on racing conditions, hybrid drive is used in this case not only for extra power, but also to save fuel. This again increases the efficiency and, accordingly, the performance of the Porsche 911 GT3 R Hybrid, by reducing the weight of the fuel tank or making pit stops less frequent, for example.

Porsche Intelligent Performance

The Porsche 911 GT3 R Hybrid is a perfect example of the Porsche Intelligent Performance philosophy, a principle to be found in every Porsche and defined as more power on less fuel, more efficiency and lower CO2 emissions - on the race track and on the road. Already, customers can buy a Porsche 911 coupe with a six-cylinder 345 bhp engine which can return nearly 30mpg Combined and produces just 225 g/km CO2; a feat unrivalled in its performance class and just one example of the application of Porsche Intelligent Performance to maintain outstanding driving dynamics yet lower running costs and environmental impact.

Devising smart, individual engineering solutions to combine performance and efficiency with everyday usability is something for which Porsche is renowned, and is evident in such developments as lightweight body construction methods, Porsche Ceramic Composite Brakes (PCCB) and the Porsche Doppelkupplungsgetreibe (PDK) double-clutch gearbox.

Porsche 930 Turbo
The Porsche 930 (usually pronounced nine-thirty) was a sports car built by Porsche, 930 actually being the "type number" for the pre-964 generation Porsche 911 Turbo produced between 1975 and 1989. It was Porsche's top-of-the-range model for its entire production duration and at the time of its introduction the fastest production car available in Germany.

Model history
Porsche began experimenting with turbocharging technology on their race cars during the late 1950s, and in 1972 began development on a turbocharged version of the 911. Porsche originally needed to produce the car in order to comply with homologation regulations and had intended on marketing it as a street legal race vehicle like the 1973 Carrera 2.7 RS. When the homologation rules changed, Porsche continued to develop the car anyway, deciding to make it a fully-equipped variant of the 911 that would top the model range and give Porsche a more direct competitor to vehicles from Ferrari and Lamborghini, which were more expensive and more exclusive than the standard 911. Although Porsche no longer needed the car to meet homologation requirements, it proved a viable platform for racing vehicles, and became the basis for the 934 and 935 race cars. Ferdinand "Ferry" Porsche, who was running the company at the time, handed development of the vehicle over to Ernst Fuhrmann, who adapted the turbo-technology originally developed for the 917/30 CAN-AM car to the 3.0 litre flat-six from the Carrera RS 3.0, creating what Porsche internally dubbed as 930. Total output from the engine was 260 PS (191 kW; 256 hp), much more than the standard Carrera. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and stronger gearbox became part of the package, although some consumers were unhappy with Porsche's use of a 4-speed whilst a 5-speed manual was available in the "lesser" Carrera. A "Whale-Tail" rear spoiler was installed to help vent more air to the engine and help create more downforce at the rear of the vehicle, and wider rear wheels with upgraded tires combined with flared wheelarches were added to increase the 911's width and grip, making it more stable.

Porsche badged the vehicle simply as "Turbo" (although early U.S. units were badged as "Turbo Carrera") and debuted it at the Paris Auto Show in October 1974 before putting it on sale in the spring of 1975; export to the United States began in 1976.

The Porsche 930 proved very fast but also very demanding. The 911 was prone to oversteer because of its rear engine layout and short wheelbase; combining those traits with the power of the turbocharged motor, which exhibited significant turbo-lag, meant driving the car required more skill to drive at the edge of its (higher) level of performance. Even though the rear engine layout provided superior traction, sudden bursts of power to the rear wheels in mid-corner could break the tires loose, causing the car to literally spin out of control. This effect was amplified if an unexperienced driver would instinctively lift the throttle in reaction. The vehicle needed to be kept at high revs during spirited driving to minimise the turbo lag. Skilled drivers quickly learned how to drive the Porsche 930 properly, and with that knowledge came the ability to drive the car above and beyond the levels of most other sports cars. Nevertheless, some fatal accidents resulted in product liability law suits brought against Porsche in the US, where Ralph Nader had made his name criticizing the rear engine-rear wheel drive layout of the Chevrolet Corvair.

Porsche made its first and most significant upgrades to the Porsche 930 for 1978, enlarging the engine to 3.3 litres and adding an air-to-air intercooler. By cooling the pressurized air charge, the intercooler helped increase power output to 300 hp (DIN); the rear 'whale tail' spoiler was re-profiled and raised slightly to make room for the intercooler. Porsche also upgraded the brakes to units similar to those used on the 917 racecar.

Changing emissions regulations in Japan and the U.S. forced Porsche to withdraw the 930 from those markets in 1980. Believing the 928 would eventually replace the 911, Fuhrmann cut-back spending on the model, and it was not until Fuhrmann's resignation the company finally committed the financing to re-regulate the car.

The Porsche 930 remained available in Europe, and for 1983 a 330 PS (243 kW; 325 hp) performance option became available on a build-to-order basis from Porsche. With the add-on came a 4-pipe exhaust system and an additional oil-cooler requiring a remodelled front spoiler and units bearing the add-on often featured additional ventilation holes in the rear fenders and modified rockers.

Porsche offered a "Flachbau" ("slantnose") Porsche 930 under the "Sonderwunschprogramm" (special order) program beginning in 1981, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end. Each Flachbau unit was handcrafted by remodeling the front fenders. So few were built that the slantnose units often commanded a high premium over sticker, adding to the fact that they required a premium of up to 60 per cent (highly indivdualized cars even more) over the standard price. Several sources claim the factory built 948 units. The Flachbau units delivered in Europe usually featured the 330 hp (246 kW) performance kit.

928 sales had risen slightly by the 1985 model year, but there was still some question as to if it were truly capable of superseding the 911 as the company's premier model, and for 1986 Porsche re-introduced the Porsche 930 to the Japanese and U.S. markets, now featuring an emission-controlled engine producing 282 PS (207 kW; 278 hp). At the same time Porsche introduced the Targa and Cabriolet variants, both of which proved popular.

Porsche discontinued the 930 after model year 1989 when its underlying "G-Series" platform was being replaced by the 964. '89 models were the only versions of the Porsche 930 to feature a 5-speed transmission. A turbo version of the 964 officially succeeded the Porsche 930 in 1991 with a modified version of the same 3.3 litre flat-6 engine and a 5-speed transmission.

Porsche 901

Porsche 901 was the name originally intended for the Porsche 911. By the early 1960s, Porsche project design numbers had reached into the 800s. For instance, Porsche's 1962 F1 model was called Porsche 804.

At the Internationale Automobil-Ausstellung (Frankfurt Motor Show) in Frankfurt in September 1963, Porsche presented its successor to the Porsche 356 as the Porsche 901. It took several more months until the cars was sold to customers. In late 1964, after having sold about 82 cars, the Porsche 901 was presented at the Paris Auto Salon. There, French car maker Peugeot objected to Porsche using any three digit number where the middle number was 0, owning the naming rights and having already sold many models with that scheme.

So, Porsche simply replaced the middle 0 with a 1, and called the car Porsche 911.

Also, other Porsche models were affected, which were primarily intended for racing but also sold as road legal cars. Here, Porsche kept the internal part number of 90x, but sold the car with a name, like: Porsche 904 as Carrera GTS, Porsche 906 as Carrera 6.

Porsche enthusiasts continue to refer to these cars by their three digit design numbers.

Later, Porsche introduced pure racing cars which were not sold for road use, so not competing with any road-going Peugeot. These carried the design numbers: Porsche 907, Porsche 908, Porsche 909.

Nearly three decades later, a 905 was entered in the 1991 24 Hours of Le Mans, but not by Porsche (which then had won over a dozen times already), but by Peugeot: The Peugeot 905 won twice, in 1992 and in 1993. A Peugeot 908 Diesel was entered in the 2008 event, and won in 2009. Peugeot never used the number 901, though.

Additionally, the 901 number is used among Porsche enthusiasts as shorthand to identify the aluminum 5-Speed transmission used in early 911s, the part number for these transmissions used an 11 digit code that began with 901 as did many other parts on the early cars. Later 911s from 1969 used a different magnesium case and a part number beginning with 911.

Porsche 550 Spyder

The Porsche 550 was a sports car produced by Porsche from 1953-1956. Inspired by the Porsche 356 which was created by Ferry Porsche, and some spyder prototypes built and raced by Walter Glöckler starting in 1951, the factory decided to build a car designed for use in auto racing. The model Porsche 550 Spyder was introduced at the 1953 Paris Auto Show. The Porsche 550 was very low to the ground, in order to be efficient for racing. In fact, former German Formula One racer Hans Herrmann drove it under closed railroad crossing gates during the 1954 Mille Miglia.

The Porsche 550 / 1500RS or Spyder became known as the "Giant Killer". The later 1956 evolution version of the model, the 550A, which had a lighter and more rigid spaceframe chassis, gave Porsche its first overall win in a major sports car racing event, the 1956 Targa Florio.

Its successor from 1957 onwards, the Porsche 718, was even more successful, scoring points in Formula One as late as 1963. A descendant of the Porsche 550 is generally considered to be the Porsche Boxster S 550 Spyder; the Spyder name was effectively resurrected with the RS Spyder Le Mans Prototype.

The Porsche 550 "Little Bastard", serial number 550-0055 is best known for being the car in which James Dean was killed on September 30, 1955.
