Trois berlines Audi 200 Quattro furent choisies et spécialement préparées pour ce projet conçu par le directeur général exécutif d'Audi, le Dr Ferdinand Piëch.Caractérisées par des appendices aérodynamiques légers en Kevlar à l'avant et à l'arrière (qui abaissaient le Cx à 0,27) et par un toit et des portières en aluminium, ces voitures étaient équipées du moteur cinq cylindres en ligne de 2,2 litres alimenté par turbo et catalysé qui, préparé pour les records, délivrait au maximum 650 ch. Deux de ces voitures reçurent des moteurs à 20 soupapes, mais la troisième – objet de la vente – a une culasse à 25 soupapes comme l'a confirmé l'ancien directeur du département Technologie des Moteurs, Ulrich Baretzky. La voiture proposée ici est donc unique. Les voitures furent aussi équipées d'un arceau cage de sécurité et de vitrages latéraux en plastique, tandis que les roues étaient en alliage de magnésium.La piste de vitesse de Nardò, en Italie du sud (ancien circuit d'essai de FIAT) fut choisie pour cet assaut sur les records des 500 et 1 000 km détenus par la C111 à 320,78 km/h et 318,30 km/h respectivement. Le système de traction intégrale Quattro d'Audi s'était déjà illustré dans les rallyes internationaux et le but de la tentative de Nardò visait à démontrer sa capacité d'endurer des efforts soutenus à très grande vitesse sur la route.Le directeur du développement d'Audi, van Basshuysen, prit la direction des opérations sur l'anneau de vitesse de 12,65 km du 1er au 4 avril 1988. Une équipe de 13 pilotes (majoritairement allemands) avait été recrutée pour ces tentatives de record que soutenaient Michelin, Shell, Boge et Ermitee. Un réservoir de très grande capacité (340 litres) fut installé afin de réduire le nombre d'arrêts ravitaillement, qui ne demandaient que 25 secondes pour refaire le plein grâce à un système de remplissage rapide type aviation. Pour gagner du temps sur les changements de roues, les voitures furent équipées d'un système de crics pneumatiques intégrés, les roues étant elles-mêmes fixées par un seul gros écrou et serrées/desserrées au moyen d'un outil pneumatique. Un système de contrôle de pression des pneus fut installé pour améliorer la sécurité. Les pilotes étaient en contact radio permanent avec le stand et les fonctions essentielles de la voiture étaient enregistrées par télémétric.Deux records de vitesse furent battus : 500 km à 324, 509 km/h et 1 000 km à 326, 403 km/h. Malheureusement, la tentative dut être abandonnée lorsqu'une crevaison causa un accident (châssis n° N6000/2). Audi avait été à l'époque engagée dans d'autres tentatives de record dont celui de 30 000 km. Audi vendit par la suite les trois voitures de record : deux ont été détruites, si bien que cette voiture, châssis numéro 1 est la seule survivante.Un des pilotes de ces records, le Dr Siegfried « Sigi » Brunn, connu comme « le dentiste le plus rapide d'Allemagne », avait commencé par rouler à une moyenne de 350 km/h après seulement trois tours de chauffe ! Le Dr Brunn, racheta la voiture à Audi après la réussite de la tentative. Le propriétaire actuel acheta directement l'Audi à Sigi Brunn. Quelques pièces de rechange (roues, nouveaux éléments de carrosserie, suspension) sont disponibles par négociation séparée après la vente et sur demande. Immobilisée depuis les années 1990, cette voiture est une des plus importantes voitures de l'histoire de la marque proposée en vente publique au cours de ces dernières années.1988 Audi 200 Turbo Quattro 'Nardò 6000' Speed Record CarChassis no. N6000/1Capitalising on the outstanding success of its pioneering, five-cylinder, four-wheel-drive Quattro rally cars, Audi took up a new challenge in 1988: to break the speed records held by Mercedes-Benz's diesel-powered C111 experimental prototype since 1978. Three identical Audi 200 Quattro saloons were selected and specially prepared for the project, which was the brainchild of Audi CEO, Dr Ferdinand Piëch. Featuring lightweight Kevlar aerodynamic modifications to the front and rear bodywork (lowering the drag coefficient to 0.27 Cd) and an aluminium roof and doors, these cars were powered by Audi's 2.2-litre inline five-cylinder engine, which in turbocharged and catalysed record-breaker form produced a maximum of 650bhp. Two of the cars were built with 20-valve engines while the other one – that offered here – had a 25-valve engine, as confirmed by Audi Sport's former Head of Engine Technology, Ulrich Baretzky. The car on offer is therefore unique. There was also a built-in roll cage and plastic side windows, while the wheels were of lightweight magnesium. The Nardò Ring in southern Italy (formerly FIAT's test track) was chosen for the attempts on the 500km and 1,000km records, held by the C111 at 320.78km/h and 318.30km/h respectively. Audi's Quattro all-wheel-drive system had already proven itself in international rallying, and the aim of the Nardò exercise was to demonstrate its ability to sustain continuous loads at very high speeds on the road. Audi's Head of Development Richard van Basshuysen directed proceedings at the 12.65km circular track, which took place from 1st to 4th April 1988. A team of 13 (mainly German) drivers had been recruited for the record attempt, while sponsorship came from Michelin, Shell, Boge, and Emitec. An extra-large (340-litre) fuel tank was installed, minimising the number of stops, which took only 25 seconds to replenish thanks to an aerospace quick-filler. To speed up wheel changes, the cars were equipped with a built-in, pneumatically operated jacking system, while the wheels themselves were secured by a single large-diameter nut, locked/unlocked by a pneumatic gun. A tyre pressure-monitoring system was used for increased safety. Drivers were in radio contact with the pits at all times, and the cars' vital functions were telemetrically monitored. ...
