Ultra-Grand Touring 1999–2003
Engaging wholeheartedly in the “mine’s bigger than yours” supercar competition among the major auto makers, Porsche reached back to an aborted Le Mans
Engaging wholeheartedly in the “mine’s bigger than yours” supercar competition among the major auto makers, Porsche reached back to an aborted Le Mans contender for the technology to create a supercar of its own to show that the Zuffenhausen company wasn’t ready to yield to anyone when it came to ultra-quick and ultra-costly sports cars.
I
n 2003 Porsche’s Leipzig plant manager Siegfried Bülow had to go back to his 8,000-strong pool of potential employees employ ees because he anticipated needing 70 more staff to carry out another task for Porsche: the assembly at Leipzig of the Carrera GT. At the Detroit Show on January 8, 2002, Wendelin Wiedeking announced that in the second half of 2003 Porsche would go ahead with the production of a refined version of the exotic open two-seater that it unveiled, to general astonishment, at the Paris Louvre on September 28, 2000. For its new model Porsche revived revived a de signation first used in 1957 for a lightweight version of the four-cam Carrera, a car cut o ut for competition. The The twenty-first-century Carrera GT, howev however, er, was conceived not as a racer but as t he ultimate roadgoing Porsche. “With the Above left: Carrera GT,” said Wiedeking, “we A cutaway drawing want to do more than just demonrevealing the machinery strate our technical competence in (see page 1486) the sports -car segme nt.

Carrera GT Gestation
The new Carrera GT traced its origins to cars built for racing. Apart from its success at Le Mans, Porsche was shut out in its 1998 GT-racing season. Breathing asthmatically through restrictors, its tur bocharged engines were denied the power that could have made them competitiv competitive. e. Particularly lacking, said Norbert Singer, were the mid-range torque and response needed to accelerate away from the slow corners that proliferated proliferated on the latest race-track designs. Drawing a line under the turbo-blow turbo-blown n era, motorsports chief Herbert Ampferer recommended that Porsche face its racing future with naturally aspirated engines. Work on such

an engine was put in hand to power a new open GT1 twoseater, the LMP 2000. On November 28, 1998, Porsche announced at its annual motorsports gathering that it would not compete in 1999 but would have a new racer ready for the 2000 season. “We “We decided to stop for one year,” year,” said Horst Marchart, “and develop a complete new car.” Ampferer had recent experience to draw upon: the V-10 of 3.5 liters that he’d he’d built and tested to take the place of the Type 3512 V-12 supplied to the Footwork Arrows team. His engineers, led by Thomas Ludenbach, scaled up the concept of this engine to 5.5 liters, keeping the 68-degree vee angle that they’d they’d used with the earlier unit. This angle had been determined as the optimum a fter an extensive series of analytical studies of bank-angle options and 16 different firing orders. That it was not identical to the 72-degree spacing of the crankshaft’s big-end throws proved proved irrelevant in practice. Twin overhead cams for each cylinder bank were geardriven and opened four valves per cylinder. The V-10’s main castings were aluminum, using a Nikasil coating directly on the cylinder bores. The cylinders were cast integrally with the block to keep the engine as short as possible—22½ inches long—and also stiff enough to be used as the rear portion of the frame.
Much like Honda’s Formula One V-12, the new Porsche ten grouped its pumps and accessories in a case that extended across the front of the crankcase below the crankshaft nose, whence its train of gears was turned. A single water pump on the right side served both cylinder banks. The left-hand bank was offset forwar forward d of its mate to accommodate the sideby-side titanium connecting rods. Butterfly throttles controlled the Motronic-generated Motronic-gener ated mixture to an engine capable of revving to 10,000 rpm and producing 680 horsepower. For the rest of the LMP 2000 Ampferer’s crew had drivetrain and suspension componentry that was carried over, with improvements, from the GT1/98. Britain’s Lola Composites produced a new carbon-fiber frame tub to Porsche’s designs, while Norbert Singer went back to the tunnel to develop an open body—also in carbon fiber—with marked bulges over its wheelhouses. Although the program suffered suffered some delays, a prototype LMP 2000 was ready for tests at Weissach by the beginning of November 1999. Among its first testers were Allan McNish and Bob Wollek, the latter calling it “an excellent car.” All that remained was to marry it to Porsche’s unmatched 24-hourracing expertise and subject it to Weissach’s rough roads and rollers and the long grinds around Paul Ricard. But But this was not to be. On November 21 Porsche announced that the project would be halted. This was a “business decision,” it said, driven by by the need to concentrate all engineering resources on the development of its Cayenne. Cancellation of the LMP 2000 was a stunning disappointment, wrote Mike Cotton. “Many people working at Weissach have been betrayed by Dr. Wiedeking’s ‘U’-turn on motorsport,” sport, ” he said, “not least the dozens of engineers and technicians who have have put their hearts and souls into the creation of a new challenger, a vehicle that might well have been Porsche’s 17th Le Mans winner.” Were Ferry Porsche still living, Cotton speculated, the promise of a year earlier would not have been broken. In the two years since Ferry’s death, the Briton thought, “Porsche “Porsche AG AG has become a vastly different different company to the one he knew, in which the accountants have finally triumphed over the engineers. In 1999, it seems, profit comes before pride.” Cotton was not alone in judging this decision harshly. Popular and TV-friendly Supercup races were all very well, but Porsche’s friends and allies were accustomed to see it jousting

Putting its reputation on the line in racing over half a century was an important foundation of the respect afforded the Porsche brand. New boss Wiedeking had backed the GTracing efforts of 1996 through 1998, despite meager results in the latter two years. Now he was prepared to take a chance that Porsche’s reputation could survive a longer furlough from the tracks.

Responding to Supercar Competition His decision to halt the LMP 2000 project did not imply that the Porsche chief lacked a competitive character. In fact he was not one to shy from a challenge, especially especially in the commercial arena. And there, in 1999, he perceiv perceived ed threats to Porsche Por sche that were just as menacing as any race-track attacks. Other car makers were preparing and unvei unveilling exotic sports cars at the apogee of the market. Ford’s Ford’s Aston Martin revealed rev ealed its Vanquish Vanquish and MercedesBenz its SLR, to be built in Britain by McLaren. BMW introduced its upscale Z8. Aud Audacious acious initiatives from the VW Group included Lamborghinis, a revival of Bugatti, Bentley’ss Hunadieres concept car Bentley’ and—most outrageous of all—the Volkswagen W12 open two-seater with its 500-horsepower W-12 engine, a stunning s ports car that VW said it planned to produce. 1 These provocations spurred Wiedeking into action. “In recent times,” times,” he said, “the giants in the business have discovered the sports car, serving—you might say—some special cream on top of their big cakes. More and more companies are now rounding off their model range with high-performance vehicles claimed to be ‘sporting’ and ‘dynamic.’” ‘dynamic.’” Porsche wasn’t going to play second fiddle to these upstarts. Aston Martin, BMW and Mercedes-Benz were one thing, but Volkswagen! It was time 1. The The decision was later reversed, and the W12 did not go into production.

It can also showcase our abilities in design and engineering. engineering.” ” “There were were no design restrictions, restrictions,” ” said one of his troops, Harm Lagaay, “and no need to use any carryover parts from existing projects. The only brief was to make a strong statement in the field of top-end sports cars, which Porsche Porsche had not made since the 959 of the mid-1980s.” Borrowing Borrowing from other projects wasn’t prohibited, so use was made of the 5.5liter V-10 that Herbert Ampferer’s racers were developing for the LMP 2000. It kept its small-diameter racing clutch, and was detuned initially to 558 bhp at 7,500 rpm and 442 lb-ft of torque at 4,500 rpm.2 While August Achleitner, Porsche’s manager of vehicle concepts, initially oversaw the planning of the Carrera GT and the building of the first two prototypes, the final production version was designed by a special team headed by Michael Hölscher. In a last project before his retirement Weissach veteran Norbert Singer took charge of the aerodynamics. Michael Laub oversaw the suspension and chassis, Dieter Steinhauser the body construction and Willi Seidel the electronics. Complete-vehicle integration was assigned to Bernd Zackl while the immensely experienced Roland Kussmaul was technical project leader. As test driver the talents of Porsche-contracted Walter Röhrl were at the ready. Final development development of the powertrain was under the direction of Bernd Ramler, formerly formerly a designer of competition 2. It was noted at the time that the horsepower figure was exactly exactly 1 bhp higher than that announced by Mercedes-Benz for its SLR roadster. “It could be corrected farther upward,” said Wendelin Wiedeking.

engines for Mercedes-Benz racing arm AMG. During the V-10 V-10 engine’s perfection its bore was enlarged by 2 mm to 98.0 mm, which with its 76.0 mm stroke gave gave 5,733 cc. Designated the M80, it continued to have a rigid closed-deck aluminum block whose bores were Nikasil-coated to provide a reliable running surface. During development the block’s deck height was raised 7 mm to make room for taller slipper-type pistons that had three rings instead of the two that sufficed for the racing verversion. Ti Titanium tanium connecting rods joined pistons to crankshaft. In the interest of freedom from vibration the engine was not asked to contribute to the strength of the rear of the chassis as it was when fitted to its racing counterpart and to the first two prototypes of the Ca rrera GT. The V-10’s top end flaunted two camshafts per bank. Replacing the racing version’s version’s noisy gear drive were chains. A chain to each bank drov drove e a fine-pitched spur gear which in turn rotated gears on the camshaft noses. In the inlet cam’s drive gear was the unit giving VarioCam phasing of the inlet-lobe timing over a 40-degree range. Unusually for a racing-bred engine, the bearings carrying the camshafts were between the pairs of cam lobes for each cylinder cylinder.. Racing engines of the period usually put the bearings between the pairs of cam lobes to get the ultimate in stiffness. Cup-type tappets took side thrust from the cam lobes. M80 operation was under the control of its Bosch Motronic ME7.1.1 system, which fired the same special Beru coils and plugs for each cylinder that were developed for the Cayenne’s V-8. Fuel injection was sequential to multiple points. Each bank of five cylinders had its own cast-

Weighing 472 pounds, 66 pounds more than its racing predecessor, the the vee-ten sat low in the chassis thanks to the battery of external pumps for its dry-sump system. An array of nine scavenging pumps cleared the oil, five five from the sump and the rest from the valvetrain. Cooled by by an oil/water heat exchanger and stripped of air bubbles, oil was delivered delivered to a reservoirr cast into the transaxle housing as was the practice in reservoi the GT1/98. For pressure a single pump sufficed. All accessories were grouped at the front of the engine and driven by flat flat grooved belts. Here, in a production Porsche, was the realization at last of the V-10 engine for the “F-Wagen” that the Porsche team designed during 1938 and completed at the beginning of 1939. That Type 114 sports car would have had shaft drive to its overhead cams and only 20 instead of 40 valves for its 1.5 liters. Nevertheless Nevertheless it was destined for a mid-engined sports car, exactly the formula of the Carrera GT. It would not however have enjoyed the latter’s 612 net bhp at 8,000 rpm and 437 lb-ft of torque at 5,750 rpm. The The new pure-bred ten was limited to a maximum of 8,700 rpm.
Transverse Transmission
1478
Entirely new to Porsche technology was a transverse-shaft transaxle tucked close behind the final-driv final-drive e gears of the Car Car-rera GT. Originally designed for the LMP 2000, this was in line with modern racing-car technology as revi revived ved by Ferrari for its Formula One cars in 1975. A key advantage was that it brought the heavy bulk of the gears more forward, reducing reducing the overhung masses at the rear of the chassis to gain more agile handling. From Fr om the clutch the drive went to the center of the lower or input shaft of the all-indirect box, driving through a pair of spiral-bevel gears. The input shaft was designed as an inner shaft linked to an outer casing which, in combination, gave gave torsional flexibility flexibility to the drive. Lower Lower ratios of the six-speed box were on the left side and higher gears on the right, next to the reverse gearing. Unlike the racing version the Carrera GT’s transmission had synchromesh and helical teeth in the gear pairs made by Albrecht Hör’s Hö r’s Hör Technologie at Weiden, near nea r the Czech border. Hör, which had built drivetrain parts for the eminently successful Audi A8 sports-racers, carried out the transaxle’s complete design, development and manufacture. From the transaxle’s transverse driven shaft a pair of gears took the drive forward to the t he differential. The latter, from ZF, provided provided up to 30 percent control of wheelspin both on acceleration and on the overrun. As originally designed for the LMP 2000 the engine and 145-pound transaxle were set as low in the chassis as possible to achieve a ground-hugging center of gravity. This required
Top: Ceramic discs were a feature of the Carrera GT’s PCC clutch, which at 6.7 inches in diameter was just over an inch smaller in diameter than the 928’s 7.9-inch multiple-disc clutch. Bottom: Designed and built by Hör Technologie, Technologie, the Carrera GT’s transaxle received its input from the clutch (1) and a pair of spiral-bevel gears (2) turning the lower input shaft. From there the individual ratios (3) drove the output shaft, from which a pair of transfer gears (4-5) took torque to the differential and thence to the half-shafts (6).

For Porsche’s Porsche’s sportsracer, heavier heavier than an F1 car and designed for endurance, a 6.7-inch diameter was specified. This was a big step down from the 11.5-inch clutches of the 911 Turbo Turbo and GT2. To cope with this small diameter the clutch had to have multiple driven discs and suitable materials. For For racing Porsche Por sche has used triple driven discs, for example in its L e Mans-winning GT1/98. These These had carbon/carbon friction faces which were fine for racing but in a road car would need replacement as early as 10,000 miles. In its road ca rs Porsche Porsche introduced a special Fichtel & Sachs clutch on the 928 that had twin driven discs so it could be only 7 7/8 inches in diameter, again again with the aim of lowering the engine and driveline. Some three decades later twin discs were the choice for the Carrera GT as well. The rotary inertia of the clutch discs has a major effect on speed of gear-shifting; too much inertia can make shifts slow and difficult. With this in mind, and also thinking of the need to c ope with heat, Porsche decided to use silicon-carbide ceramics for the discs. Lighter than the steel alternative and heat-resistant, ceramics had already found a home at Porsche in brake dis cs. The The Weissach Weissach engineers turned to the same source, Meitingen’s SGL Brakes GmbH, to supply the ceramic discs. Eight hundred test-bench hours simulating 16,000 racing starts proved the merits of the composite of carbon with silicon carbide for this application. Supplier to many Formula One teams, Sachs Race Engineering was nominated to deliver the complete clutch assembly. Pagid provided titanium carriers for the organic linings of what was dubbed the PCCC for Porsche Porsche Ceramic Composite Clutch. A Belleville spring provided the necessary pressure while hydraulics actuated the disengagement through a cylinder concentric with the clutch output and a ball bearing. The whole package, including the PCCC weighing only 7.7 pounds, was bolted to the back of the crankcase at three points.

work for the aerospace community as well as Lamborghini, Ferrari, Ferrari, Bugatti and Italian motorcycle companies. ATR also made the carbon-fiber bodywork of the Carrera GT.The whole process of manufacturing the components for Porsche’s supercar took ATR four days. Using four different different methods to form the various frame and body elements, its peak production capability was two frames and bodies per day. The passenger-carrying central tub had integral rollover rollov er hoops to protect its two occupa nts. Between it and the engine was the 24.3-gallon fuel tank. Fabricated of six aluminum panels using a Plasmatron process whose very light localized tempe ratures ensured sound and clean seams, it also housed the fuel pumps and filters. All wiring a nd pipework from front to rear was channeled through the tub’s central backbone. Enclosing the supercar’s underside was a belly pan comprising three carbon-fiber moldings. It was shaped to develop down force just behind the front wheels and also at the rear, where air accelerated through a raised venturi. Where they intruded into the venturi the lower suspension arms were given a low-drag profile. That the venturi was not just for show was illustrated by its contribution of three-quarters of the Carrera GT’s down force at 185 mph of almost 900 pounds.
Suspension by Pushrods
1480
Suspension systems proper traced their pedigrees back to Porsche’s 1987–88 chassis for CART racing in America. This marked Weissach’s first use of pushrod suspension with the coil/damper units mounted on the frame and driven through rocker arms. The technique was revived for the GT1/98 and carried over to the stillborn LMP 2000, which gifted it to the Carrera GT. Suspension proper was of conventio conventional nal parallelwishbone design using forged aluminum parts except for the rear lower A-arms, which which were fabricated of stainless ste el. At the rear the coil/damper units were mounted atop the carbon-fiber cradle where they were visible when the rear deck was lifted, while at the front they were splayed under the cowl just in front of the windscreen. In the latter instance the 8.7-inch pushrods were made of H400 stainless-steel alloy tubing which was hydroformed to expand its crosssection through the middle to increase their stiffness. Proportions of the rocker arms, also stainless steel, were such that the springs had a mechanical advantage over the pushrods of some 1.3:1. Links from the rocker arms operated the front and rear anti-roll bars. High-placed rack-and-pinion steering was power power-assisted. -assisted. Naturally Naturall y the brakes had ceramic discs. Internally vented and cross-drilled, these measured 380 mm in front and 350 mm in the rear rear.. It was a me asure of the relati relative ve physics and dynamics that the Cayenne Turbo Turbo S had front discs of the same diameter and even bigger rotors at the rear. Brembo
Pushrods from the lower front suspension arms actuated tub-mounted rockers that drove the coil/damper units as well as long links to the front-mounted antiroll bar.
supplied aluminum monobloc calipers with six pistons apiece. ABS was fitted to the dual-circuit system. Brake and clutch pedals were cut from extruded aluminum, the same material serving for the accelerator. They pivoted at the floor from a cast-aluminum carrier. Experiments with materials for the Carrera GT’s five-spoke wheels proved that forged magnesium was 25 percent lighter than aluminum and 60 percent less hefty than steel. Thus Thus magnesium was adopted for the Japanese-made rims, which measured 9.5 x 19 inches in front and 12.5 x 20 inches in the rear. Respective sizes of the bespoke Michelin Pilot Sport 2 tires were 265/35ZR19 and 335/30ZR20. Needless to say in the crowded machinery of the Carrera GT there was no room for a spare. Packed into the Carrera GT’s nose were three radiators. Two set into the corners vented directly into the low pressure of the front wheelhouses while the outlet from a large central core of aluminum, sloped steeply forward, was ducted back into the tops of the wheelhouses. Between the radiators were horizontal columns of energy-absorbing H400 stainless, going forward to the front bumper. Similar columns of H400 were used at the rear to soak up energy in mandatory crash tests. Final track widths of the Carrera GT were similar to those of the GT1 racers at 63.5 inches in front and 62.5 in the rear, while wheelbase, lengthened lengthened during the project for aesthetics more than function, became 107.5 inches. The aesthetics were the responsibility of Harm Lagaay Lagaay,, whose task was none too easy. No recent Porsche cues or design idioms were relevant. The GT1 racers had been styled to look as m uch as possible
STYLING THE PROTOTYPES
With the coupes, as well, it was difficult to avoid results that looked 911-ish. In the next stage, the development of a full-size model, designer Tony Hatter played a key role. “We took a lot of time over it,” said Harm Lagaay. “We

like a 911, not to explore new design directions. The Boxster looked backward in style, not forward, while the 911 was a successful evolution of a classic. In meeting Wiedeking’s challenge, Lagaay needed to make a fresh start. He had to employ the most subtle of means. “Our brand is not identified by any distinctive element such as a radiator grille,” he explained, “so its personality derives from the way we design the details and handle the surfaces. The typical Porsche shape is set by the combination of surface treatment, highlighting and tension, which to a large extent comes from the transition between convex and concave shapes.” Here Lagaay and his team had the rich legacy of such dedicated artists of sheet metal as Erwin Komenda, Dick Dick Soderberg and Wolfgang Möbius upon which to draw.
Styling the Prototypes The Carrera GT was a baptismal project for a new arm of Porsche, a West Coast design studio. Porsche Engineering Services, Inc. was set up in March 1999 in Los Angeles to carry out design work for Porsche Porsche and other clients as well. That spring, the studios in both Ca lifornia and Baden-Württemberg were assigned two days of sketching concepts that would suit a super-Porsche. super-Porsche. Three of these were chosen to be modeled in one-quarter scale. When these were evaulated at the end of May 1999, one was rejected as not having enough Porsche-ness Porsche-ness and another as having insufficient aerodynamic potential. Coupe concepts were set aside at a n early stage in favor of an open car, said Harm Lagaay: “People “People who buy such a car want to be seen.”

With the coupes, as well, it was difficult to avoid results that looked 911-ish. In the next stage, the development of a full-size model, designer Tony Hatter played a key role. “We took a lot of time over it,” said Harm Lagaay. “We needed surface tension to communicate some emotion.” tion. ” Another challenge to the designers was that the car’s forms had to have high feasibility, August Achleitner told Peter Morgan: “Our stylists had a very difficult difficult job, because they had to take a ccount of the technical requirements. That makes this car different to a normal study. We didn’t want to show a car that will be watered down for production. It is very near to a production car.” That, plus interruptions, meant that the Carrera GT’s body design wasn’t ready until March of 2000. The silver-skinned silver-skinned clay model showed a sleek two-seater that artfully married elegance with aggressiveness. True to Porsche’s principles, it expressed eager urgency without the meretricious excesses of some of its big-company rivals. Its low nose with wide inlets was unremarkable; unremarkable; instead the Carrera GT’s character was expressed by the dashing sweep of curved lines on its flanks, from air vents behind its front wheels to engine-room inlets, and also by twin headrests fronting a carapace above its V-10 engine. A fine mesh over the engine was its “negligee,” “negligee,” according to Lagaay, Lagaay, both concealing and rev revealing. ealing. The wing spanning its rear deck above a central tunnel in the engine cover lifted electrically to be more effective at high speeds. The finished Carrera GTs—initially two concept cars were built—abounded in fascinating detail. Lifting their rear deck revealed viscera, coil/damper units and an oil filler and cooler, with wheel-removal wheel-removal tools in a receptacle on the left. Cladding concealed the engine. High-intensity headlamps hid under transparent fairings while neon tubes were used for turn-signal and brake lamps. Side mirrors had vee-strut mountings. During development their position was changed to give better visibility to the rear. A very high yet narrow console of magnesium separated the passengers and placed the sequential shift lever high and next to the wheel, like that of a rally car. The steering wheel itself was new to Porsche with a Y shape to its central spoke, which carried several controls. This foreshadowed the style of the similar wheel of the Cayenne. Instead of fixed dials, the concept Carrera GT used a highdefinition display to communicate with its driver. driver. He could choose either a highwa highway-touring y-touring display or one which suited closed-circuit racing, even presenting his lap times.

Assessing the Prospects The Paris launch of the Carrera GT came as a stunning surprise. The old “leaky” Porsche company was a thing of the past. Harm Lagaay explained to Peter Morgan how this was achieved: This has been an extremely inspiring project with such a small group of people, all thinking and working in the same way in creating this super-P super-Porsche. orsche. Young or o r old, it didn’t matter who was working on the project, they were all saying to themselves that this was going to be the best. I think that’s how we managed to keep it such a closely guarded secret. Those of us involved were 100 percent committed to the project, and even the best3. Here was an echo of the Buckelwagen version of the original Porsche 550 Spyder of 50 years earlier.

A feature of the Paris “reveal” was stunning action footage of Walter Röhrl driving the silver concept GT through a dramatic desert moonscape. This was filmed during the third week of August August 2000 in Nevada’s Valley of Fire State Park, Par k, northeast northea st of Las Vegas. With temperatures of 105º F and upward in the baking desert, Röhrl wished he hadn’t brought black jeans to Nevada. Driving the prototype Carrera GT was no sinecure. Its triple-plate racing clutch—not the final design—was so fragile that a gang of pushers was always at the ready to t o get it i t going. “Around “Around corners,” c orners,” however, however, said Röhrl, “it drove like an out-and-out racing car.” Some compared the Carrera GT to the 959 of almost 20 years earlier. Although both were envisioned as establishing Porsche at a new high level of the market, conceptually the newer car was the antithesis of its predecessor. The 959 was packed to the gunwales with electronics and hydraulics at the state of the art and beyond. It was the very quintessence of Porsche as a technological innovator and leader. The Carrera GT in contrast made no such claims. Its creation did lead to the filing of some 70 patents, but these related more to construction methods than to vehicle performance technology. In fact the Carrera GT proudly forswore any but the most essential electronic aids including, controversially, Porsche’s PSM system for handling control. It was an avowedly emotional interpretation of a sports-racing car for the road, much more a Dauer GT than a 959. And unlike the four-wheel-drive supercar, when built it would be homologated for sale in the good old US of A. One thing the Carrer Carrera a GT would not be was a spectacular money-loser for the company in the tradition of the 959. “You may rest assured that it is not our corporate policy to subsidize this product segment,” said Wendelin Wiedeking at the GT’s Paris launch. “Rather, each and every car we introduce must contribute to our overall overall business results. So we will test the acceptance of t he car in the market and the size of the market before taking the final decision to build the Carrera GT.” Assessing the market’s size was the tricky part, Wiedeking admitted: “Nobody really knows for sure how big the market segment is for the Carrera GT and its possible competitors,” embracing two-seater sportsmobiles costing between $300,000 and $500,000. A certain jostling for position seemed likely likely.. Producing the Carrera GT would make nonsense of a statement by sales chief Hans Riedel in the context of the Cayenne decision. “We don’t live by replacement,” he said, “but we live by discretionary income. So we want to enter larger and less volatile segments.” This fitted the Cayenne decision to a T, but it would be hard to find a smaller and more volatile segment than the one the Carrera GT would occupy. Yet Riedel had another saying that was applicable. It was: “With 12 the

Canvassing Canvas sing his dealers and distributors about demand, working with pricing in the range of $350,000 to $400,000. Hans Riedel had little difficulty in drumming up int erest in this spectacular car. By the end of 2001 more than 1,000 provisional bookings had been logged with Ludwigsburg. At that time the rumor mill ground out reports that the go-ahead to produce the Carrera GT had already been given, with spy shots showing an early double-bubble roof design. Wendelin Wiedeking Wiede king confirmed this in Detroit in January 2002. He mentioned a 1,000-car run phased over several years at a rate of two or three cars daily.
Challenge of Production
1484
Development of the Carrera GT for production was assigned Development to Weissach’s motorsports group, which faced no shortage of challenges. Replacing the engine as the rear-frame structure with a cradle added some 100 pounds to the car’s weight. The V-10 was converted from its noisy gear-train camshaft drive to the quieter chains that facilitated facilitated the use of the VarioCam system. Instead of the sequential-shift racing transmission used in the concept cars, said August Achleitner, a gate-type manual shift was used “because the Americans prefer it.” The lever was placed high, operating through a Flexball cable system.
Taming the wild racing engine with a more biddable clutch was essential. Only 6.7 inches in diameter diameter,, a twin-disc ceramic-faced ceramic-f aced clutch coped with 435 lb-ft of torque at 5,750 rpm from the 5,733 cc (98 x 76 mm) t en, which produced produced 605 bhp at 8,000 rpm in production form. A proper monocoque chassis needed to replace the provis provisional ional aluminum structure of the prototypes. For the production cars some body parts and a monocoque of carbon-fiber-reinforced resin were made by Italy’s ATR composites at Colonnella. Such amenities were required as air-conditioning, electric windows and a functional if small front trunk compartment. The latter provided storage for the two removable carbonfiber roof panels, weighing a total of only 10.6 pounds. True to the commitment made when the Carrera GT was designed, its styling was only slightly changed. Harm Lagaay asked Grant Larson to take a fresh look at Tony Tony Hatter’s work. He subtly amended its proportions, increasing front overhang on the production model. Windscreen surround changed from black to body color c olor while NACA NACA ducts now provided fresh f resh air to the engine. External door handles were concealed. Fog lamps were lost when the nose spoiler was reshaped in search of the final drag coefficient, which was 0.39. The The operation of the rear wing, which rose automatically, included a mode that kept it raised for better airflow from the rear compartment when a given engine temperature was exceeded. The final design for the Carrera GT’s interior sidelined the electronic display in favor of a conventional 911-type gauge package, albeit with a 10,000 rpm tachometer and 235 mph speedometer. The column and its controls also came from the 996. With their structures made mad e of Ke Kevlar-reinfor vlar-reinforced ced resin, the bucket seats—which lacked rake or tilt adjustments—weighed only 23 pounds apiece against 44 pounds for a 911’s seats and 29 pounds for the carbon-fiber seats of a GT3. Kevlar reinforcement also featured in the dash and other interior surfaces to protect occupants from the splintering shards that carbon fiber can produce in a crash. Both the doors and the A-pillars were reinforced by high-strength steel tubes. A finishing to uch was special optional Ascot Brown leather with a “cloud effect” finish made of the hides of “heavy southern German bulls.” That the designers were successful was hinted at by Road & Track’s comment that “the interior clev cleverly erly combines high-tech with elegance, sport with civility. civility.” ” One reason why the Carrera GT omitted a panoply of electronic add-ons and features such as four four-wheel -wheel drive was that a major objective of the project was “to keep weight as low

2.3-mile test track was handy for shakedowns of the completed cars. Pilot-line cars were ready for the production Carrera GT’s first exposure to the specialist press late in 2002. Bizarrely, the venue was a former Communist-era landing strip 2½ miles long in the former East Germany, now used as a test center by Michelin. “We “We were looking for a place where we could cou ld safely show the Carrera GT’s potential,” explained press man Jürgen Pippig. Even though the open spaces of Gross-Döllin near Schorfheide, 35 miles northeast of Berlin, offered few opportunities for over-enthusiastic reporters to hit anything, one of them managed it anyway. anyway. Within the runway’ runway’ss limits the cars could top 200 mph. Porsche would make 1,500 such supercars in three years, the world was informed at the Carrera GT’s coming-out ceremonies in the spring of 2003. The festivities began on Monday, March 3, when the charter terminal at Geneva’s airport was given fancy dress for a presentation to the press just before the opening of the city’s famous Salon. Hubris was not in short sho rt supply supp ly.. “After “After the legendary legenda ry 917 and 959,” 9 59,” said Wendelin Wiedeking, Wiedeking, “we have made our ou r mark for the third th ird time.” Sales chief Hans Riedel praised the “masterpiece of engineering skill from Weissach.” Production of the new model would begin in the autumn, the press men were told. The next day the show car was on Porsche’s stand at Geneva.
Porsche raised the glamour stakes in May in Monte Carlo before the Monaco Grand Prix. With Cartier and Sunseeker it hosted a glittering GT-centered reception for 150 invited guests. Then before the Porsche Michelin Supercup race Michael Hölscher had the honor of pedaling the silver car for two laps of the Grand Prix circuit. This was just the right audience for a car base-priced at €390,000 but actually selling, in Germany, for €452,690. List price in Britain was £330,000 and in America $440,000. This was higher than the $399,000 initially announced to American dealers, who had also been told that production would be limited to 1,000 cars. In Japan, said Car Graphic, “you won’t get much change out of $500,000 but we’re tempted to say it’s worth every cent. We just didn’t want to give it back, such was the power, sound, feel, shattering performance and all-round charisma of this thi s latest Por Porsche sche superstar. su perstar.” ” “Work “Work the throttle, brakes and clutch right,” reported Excellence, “and the Carrera GT rewards with an adrenaline rush beyond any we’ve experienced in a road-going Porsche. Here’s a sports car with shocking performance that’s usable on real roads.”
Real-World Reactions Had Porsche gone too far in taming its supercar? “The crux of this test,” summed up Autocar, “is that Porsche has somehow so mehow managed to make its fastest production car feel like a 600 bhp Boxster. For For the engineers charged with rendering such power usable (in the broadest possible sense) and for the majority of us, that t hat is the t he Carrera GT’s greatest achievement. And yet

said Kevin Smith in Motor Trend. “Out of some 30 starts,” found an Excellence tester on the streets of San Francisco, “I’ll stall the big V-10 once for every cylinder.” For some Carrera GT buyers the clutch was a fatal flaw; one sold his car because he couldn’t start it on “any kind of a hill.”

said Kevin Smith in Motor Trend. “Out of some 30 starts,” found an Excellence tester on the streets of San Francisco, “I’ll stall the big V-10 once for every cylinder.” For some Carrera GT buyers the clutch was a fatal flaw; one sold his car because he couldn’t start it on “any kind of a hill.” There was a trick to it, reported Kevin Jeannette of Gunnar Racing in the pages of Panorama. “The “The Carrera GT doesn’t have a standard clutch arrangement, arrangement,” ” he said. “Rather it’s an electronically electronicall y controlled deal that requires no use of the throttle to get it rolling. You simply put it in gear and let the clutch out, never never touching the gas pedal until after it gets rolling. The problem problem is in trusting the system to modulate the throttle properly. Porsche engineers have done a great job in getting the settings exactly right. However However,, most people tend to push the gas down anyway, which of course gets everything ever ything haywire and causes the engine to stall.” For more aggressive aggressive starts with traction control switched on, the clutch was ideal, found Road & Track: “Holding the engine at 3,000 rpm and dropping the clutch produced ample wheelspin to catapult the car to 60 mph in 3.6 seconds and to the quarter-mile mark in 11.3 seconds at 131.6 mph.” Though not quite so quick as a Ferrari Enzo, which had more power and less weight, this was performance to spare. Speeds in gears at 8,300 rpm were 50 mph in first, 86 in second, 112 in third, 147 in fourth, 175 in fifth and 205 in top. If just over 200 mph were seen as slow for a twenty-first-century supercar, said tester Walter Röhrl, “What is the need for going faster?” He had a point. Exercising the Carrera GT as it was meant to be driven offered “biblical power, power, spine-tingling noises, the torque of an avalanche and raw speed like you simply wouldn’t believe,” raved Britain’s Jeremy Clarkson. “This “This is the best, most amazing, most stupendous engine that I’ve ever come across. All cars have a moment when you feel the power start to lose its war with the aerodynamics. But this one just keeps on going. 150. 170. 200.

Their Their new exhaust system was guaranteed to produce a “deep and sonorous tone.” Noises were part of the Carrera GT experience, Pete Stout reported in Excellence: “The idle is accompanied by gearbox rattles. Lots of ’em. Its gearbox noise increases as you accelerate in first gear, sounding more than a bit truck-like. The total frenzy of the V-10 is intoxicating, even when traveling from stoplight to stoplight at legal speeds. The The GT accumulates speed with a shriek that’s pure race car. Its soundtrack offers all the sounds I trek to L aguna Seca or Sears Point just to listen to. The difference is that a mere enthusiast, rather than a works driver, is making them.” Handling and grip were superb, testers reported. While Porsche claimed cornering capabil capability ity of up to 1.35 g, Road & Track measured a commendable 0.99 g on “a less-than-ideal and dusty” skid pad. “The “The car is quickly guided to the apex with stability, stability,” ” R&T found. Applying power, it added, a dded, “the driver has to be patient. Too eager on the throttle and the rear will step out. Even then the onset of oversteer is so progressive that it will never catch you by surprise.” It was a different story if rear traction were lost when entering a corner, said Top Gear : “You’re history. If the back comes round when you turn in, it’s almost impossible to catch. There is absolutely nothing you can do to rescue the situation.” situation. ” Here was clear conflict with the R&T verdict that A high perspective of the final Carrera GT showed its continued use of the “negligee” above the engine that concealed yet revealed in the spirit of that item of feminine lingerie.

With its roof panels in place the Carrera GT was snug but when they were removed, found Autocar, “the buffeting in the cabin at 100 mph-plus is enough to have you blinking to stop the wind licking your eyeballs. It seems an unfortunate oversight in an otherwise complete package.” Another fault, owners discovered, was the open gap in the fenders behind the front wheels. Sticky tires shot dirt and gravel through the gap, even reaching the rear scoops that cooled the engine bay. In America aftermarket screens were made, aping the mesh of the engine covers, to solve this problem. To cope with the long, low nose and its tendency to scrape on the slightest incline, Germany’s edo competition offered an electrohydraulic nose-lift system.
Grand Touring Adventures May 6, 2006, saw production of the Carrera GT end at Leipzig. In fact fact demand had been softening since the autumn of 2005, affected by the availability availability of used cars at substantial discounts, and the assembly team cut back from 70 to 22.

The cancelled cars had been scheduled for sale in the US, where dealers—some of whom had been critical of Porsche’s decision to make so many—did not bemoan their failure to arrive.

He experienced the full assault of customer care Porsche-style: “They “They asked me if I wanted a loaner car to try one out, then I got a key chain, they they sent me a jacket, I got a hat, I got books about the car, I got a letter telling me when the car would be in.

Record attempts were to be made and he was invited.

This didn’t mean that the Carrera GT’s owners failed to explore its considerable potential on both street and track, sometimes with consequences both costly and tragic.

Although PSM would have availed little in this head-on crash into a retaining wall at 145 mph, plaintiffs argued that it was “a modern life-saving safety feature” that Porsche “inexplicably failed” to provide. In depositions from Porsche engineers, reported John Draneas, “one testified that Porsche did not think that its PSM system would work on the Carrera GT because the car’s frame structure and suspension mountings would create strong vibrations that would interfere with its operation. The other engineer testified that PSM was not offered because the customers didn’t want it.” In this lawsuit the argument was moot because Porsche was judged a minor contributor to the fatal crash, ponying up only 8 percent of the reported $4.5 million settlement.

Here was irony indeed, for in the development of Porsche’s previous supercar, the 959, Helmuth Bott eschewed none of the most advanced means of endowing his creation with optimum stability.

Completing his economic a nd engineering education in Munich, he joined BMW as a trainee in 1984. His curriculum vitae there included two years as product manager for coupes and special engines. From 1994
Dürheimer headed R&D and product management for BMW’s motorcycle arm where, as he said, “I was trying to get them interested in racing, but getting no response.” Thus Dürheimer was susceptible when, in 1998, “someone contacted me and said, ‘Are you interested in sports cars?’ So I said, ‘Why not?’ I already knew something about Weissach from the joint work we’d done on motorcycle projects, so I appreciated the strength of the individual departments.” Wolfgang Dürheimer joined Porsche in January 1999 with the assignment of working on the Type 996. Only after his arrival did the bombshell of Marchart’s retirement explode, propelling the youthful yet experienced engineer into his board position. Supervisory-board Supervisory-boar d chairman Helmut Sihler welcomed this new-generation technical chief. “Young, talented yet very experienced people must and will constitute the future of our company,” said Sihler. “In recent years Wolfgang Dürheimer not only has shown what he can do but also has grasped the product and company philosophy of Porsche in a visible and vital manner.” Commenting about his new job, Dürheimer said: “We “We know what we have to do. We are pure, and we remain pure. We don’t need any bric-a-brac. The attractiveness of our cars lies in their purity. We know that Porsche drivers appreciate that, and they’ll also be able to do that in the future.” Evolution rather than rev revolution olution was his declared objective: “The “The new must be new, without making the old look old.” Like Ulrich Bez before him, Dürheimer brought some of BMW’s engineering ma nagement methods to Porsche. Paying Paying a compliment to the knowledge and competence he found at Weissach, he “s trengthened the cooperation, secured the lateral connections between departments and optimized the information flow.” The new top engineer considered it a “prerequisite to develop and implement a completely new organization model. I’ve introduced a new upper-level upper-level department whose mission is described by its name: ‘Concepts, Innovation Innovation and Computer-Driven Technologies.’” For the Carrera GT, he added, “we’re working flat out on this development, which represents racing technology for the road. road.” ” While his motorsports people were developing developing the GT GT,, Dürheimer said that “we can very well do without participation in major motorsports until we’ve completed this project. project.” ” Here he touched on a topic of intense interest to all Porsche enthusiasts. After the disappointment of its parking of the LMP 2000, the company had had little to say about a possible return to the front lines of the s port that had made its reputation. The only news was no news. Committed as he was to bringing the Carrera GT to market at the end of 2003, said Herbert Ampferer, Ampferer, he had no time to prepare for 2004. Thus 2005 was the earliest that any toplevel initiative could be launched by Porsche. In fact that year found the wraps coming off the first pure racing Porsche Porsche to take to the track since the GT1/98. 1491
