3 What links the racing version and the street-legal version? 30,000 racing victories and one assembly line. Motorsport history isn t written in a couple of hours, days or weeks. Motorsport history has to develop or be developed, such as by our engineers. They ve been working on this for years in the untouched countryside of the Stuttgart region, at the heart and soul of Porsche and Porsche Motorsport the Development Centre in Weissach and our motorsport manufacturing facility in Flacht. Both locations are inextricably linked: each Porsche is fitted with technologies that have been designed for both the road and for the racetrack. The best example is the new Porsche 911 GT3 Cup. Based on the 911, its bodyshell is created on the same assembly line as that of its series production counterpart. And it moves in the same direction: towards the next destination. 4 The origins

4 Some developers make only cautious tweaks to their successful models. We make effective ones. Our motor racing history gives us an obligation to strive, not only for the next victory, but also for perfection. With the new 911 GT3 Cup, we are drawing ever closer to our goal. It remains to be seen whether our dream of creating the best race car in the world ever comes true; but one thing is certain we have once again reinterpreted our vision of one of the most successful race cars ever. With over 2,300 sold, the 911 GT3 Cup is the undisputed number one among Porsche motorsport teams. The car competes in prestigious racing events around the globe, including various Porsche Carrera Cups, the GT3 Cup Challenges and the Porsche Mobil 1 Supercup. It also lines up in various GT racing series and endurance races. Why? Because the 911 GT3 Cup has got what it takes. Specifically, we re referring to a powerful yet extremely efficient engine and a sequential gearbox; the results of considerable development effort. Then there is the bodyshell construction which is based for the first time on a combination of aluminium and steel and boasts improvements not only in aerodynamics but also in safety another of our primary obligations. The vehicle 7

5 Newly developed Porsche sequential six-speed claw-shift gearbox In training for over 50 years. Perhaps that s why it gets into gear so quickly. The new Porsche 911 GT3 Cup is based on the 911 series production model a pure-bred sports car that offers an exceptional level of power and yet our engineers were able to raise it even further. How? By fighting hard for every kilogramme saved and every kilowatt added. Thanks to the weight-optimised modular racing exhaust system, the 3.8-litre flat-six engine of the new 911 GT3 Cup now produces 338 kw (460 hp). The power of the engine is transmitted to the rear axle by a racing clutch and a newly developed Porsche six-speed sequential gearbox with mechanical slip differential. The electropneumatic paddle shift system makes gear changes even faster and more efficient. The 911 GT3 Cup is also quicker to decelerate. Fit for endurance the newly developed race brake system performs impressively and will impress rival drivers, who can now be overtaken under braking even more frequently. The stability needed is provided by the extended wheelbase 100 mm longer than that of the predecessor as well as the optimised chassis. 8 The vehicle

6 1 2 1 Racing steering wheel 2 Racing seat and roll cage What s the best way to face a strong challenge? With ease. How is success achieved? By a show of strength, but only when this is combined with independent thought and actions. Take aluminium and steel, for example. Both materials have been used in the new 911 GT3 Cup for the first time to form a complete bodyshell. New measures have been coupled with new standards. The integral two-mount rescue device, for instance, enables faster vehicle rescue, which also reduces the risk of further damage. This is combined with a newly developed rescue hatch for the occupants to be extracted safely from the vehicle. Our objective was to develop the best working environment possible for the most important factor in motorsport the driver. The cockpit of the 911 GT3 Cup has therefore been refined, both functionally and formally. After all, ergonomics plays a crucial role in motor racing, too. It is a principle exemplified by a new generation of seats with fore/aft adjustment which meet all current FIA requirements, and by the racing steering wheel, which adjusts for height and reach. The most important functions are assigned to switches and are intuitive to select: from the windscreen wipers, main beam, com munications radio, power locking and alarm reset to neutral and reverse gear. The switch panel on the steering wheel has a matt carbon-weave finish. Another new feature is the colour display, which offers optimised clarity of presentation by means of additional function lights, and has a large data storage capacity. Despite all the innovations and the meticulously refined aerodynamics, a couple of aspects remain unchanged: aspects that define the success of the 911 GT3 Cup. Its heritage, for example, is Porsche through and through and can be traced back to the centre and the heart of motorsport. Another aspect is the reliability it offers under all possible conditions and, not least, the manageable running costs for the teams. The stuff that success is made of. The vehicle 11

7 On the road, the differences between us are clear. Not so much on the track. Porsche one-make championships. Motorsport is a hard-fought contest for every fraction of a second and every millimetre, for leadership, victory and glory. It s a contest in which we participate all around the world with heart and soul, with our engineers and with countless teams and drivers. What is it that drives us? The prospect of increased recognition for feats of engineering and the more than 1,000 races that have been run in 19 onemake championships over the course of 20 years. Competitions are ranked in three levels, from the entry-grade GT3 Cup Challenges to the Porsche Carrera Cups and, ultimately, the Porsche Mobil 1 Supercup, one of the fastest international one-make championships in the world. All follow the same philosophy: to promote customer racing events. All follow the same principle: equal opportunities by means of technically equal cars. The contest is fought with the same kit in the Porsche Mobil 1 Supercup from 2013, this will be the new 911 GT3 Cup and it makes the races even more exciting: what counts is the performance of the individual, from the driver to every member of the team. Porsche Motorsport handles the event organisation, provides track-side support as well as hospitality for sponsors and guests and, for all one-make championships, supplies the teams with race cars that are ready for action. Fierce challenges on the track are not the only things that await our customers. The races attract a bumper audience. Huge numbers of motorsport fans turn up to watch the races live or follow them from afar, thanks to global coverage on the television, in the press and online. The one-make championships have long since become a win-win for all. The race 13

8 The GT3 Cup Challenges. The gateway to semi-professional motorsport. Race locations include Australia, Brazil, Central Europe, Great Britain, Japan, Scandinavia, Switzerland, USA, Canada and the Middle East. Races are based on the regulations of the Porsche Carrera Cup Deutschland. The prerequisite for participation is a national licence. The Porsche Carrera Cups. From the fastest one-make championship in Germany to the international top event. The Porsche Carrera Cups play host in many countries to first-class motorsport highlights, such as the German Touring Car Masters (DTM). The tradition of the Porsche Carrera Cup spans over 20 years. Since the first Porsche Carrera Cup Deutschland was staged in 1990, a further seven Porsche Carrera Cups have become established in France, Great Britain, Scandinavia, Italy, Japan, Asia and Australia. Races are held on almost every weekend of the motorsport season. The passion to win fuels the fight for every hundredth of a second: young upstarts challenge old hands, amateurs compete with professionals. The Porsche Mobil 1 Supercup. The pinnacle of the Porsche one-make championships. Since 1993, the Porsche Mobil 1 Supercup has been held as part of the FIA Formula One World Championship and as the only Gran Turismo race series. All cars are supported by professional racing teams, which use two to three race cars in the championship. The events take place mainly as part of the European Grand Prix, with a race distance of approximately 70 kilometres. The drivers, which include established personalities alongside promising new talent, give everything they have from start to finish. After all, another prize might just be up for grabs: a career in GT racing. 14 The race

9 Two characters, one line: the ideal line. 911 GT3 Cup and 911 Carrera. Some dreams never come true. Others get better and better. Take the 911 GT3 Cup for example. It epitomises the purposeful evolution of Ferry Porsche s dream: a sports car that is just as powerful as it is efficient. What was nothing more than a vision over 60 years ago, has since been realised and reinterpreted again and again by our engineers who have contributed innovation after innovation on the way. To be more precise: on the racetrack, and from there to the road. Porsche Ceramic Composite Brake (PCCB), exhaust turbocharging and Porsche Doppelkupplung (PDK) are just a few we could mention. These technologies are deliberately designed to create the authentic motorsport experience behind the wheel of a 911, such as a a 911 GT3 Cup. Its DNA can therefore be traced categorically: from Weissach to Flacht, and from the racetrack back to the road. Just as Ferry Porsche dreamed it would be. 911 Carrera models: Fuel consumption (in l/100 km) urban extra urban combined ; CO 2 emissions g/km; CO 2 efficiency classes G/F 16 The production models
