J'ai suivi ton conseil Guillaume et j'ai enfin la réponse !
La couleur de mon missile : Code 63A = Gris Sport Classique de chez Porsche !!
Un peu étonnant... mais il semble que selon le souhait du client, les couleurs d'autres marques soient possibles... surement restreint au sein du Groupe VW ?
Voici la réponse avec quelques commentaires généraux de mon interlocuteur allemand :
Name of color: “Sportclassicgrau Uni”
Color code: 63A
Audi Individual Exclusive Painting offers the special service that makes its customers wishes/dreams come true😊 Therefore, Audi Exclusive uses from other manufacturers original colors as well.
The Audi RS6 Avant is the high-performance model of the A6 series Special features of the RS6 station wagons included flared wheel arches, oval tailpipes and modified bumpers. At the market launch, the sports station wagon, which was initially equipped with a V8 engine, produced up to 331 kW (450 hp).
The "RS" initials are taken from the German: RennSport – literally translated as "racing sport", and is Audi's ultimate 'top-tier' high-performance trim level, positioned a noticeable step above the "S" model specification level of Audi's regular model range line-up.
Like all Audi "RS" models, the RS 6 pioneers some of Audi's newest and most advanced engineering and technology, and so could be described as a halo vehicle, with the latest RS 6 Performance having the equal most powerful internal combustion engine out of all Audi models, with the same horsepower and torque as the physically larger Audi S8 Plus. Unlike the A6 and S6, however, the RS 6's engines in the
C5 and C6 iterations have not been shared with any other vehicle in Audi's lineup. However, for the C7 generation, the Audi RS 6 has the same 4.0L bi-turbo V8 engine as the Audi RS 7, with both being positioned at the top of the Audi S and RS range, and detuned variants of the same engines are found in the Audi S8, Audi A8, and Audi S6.
