The Audi S6 Plus was the first product developed by Audi’s high-performance subsidiary, quattro GmbH, and was offered from June 1996 to October 1997. The changes that the ‘Plus’ denoted were significant: Under the bonnet, the 2.2-litre turbocharged five-cylinder engine from the standard S6 was replaced by a 32-valve 4.2-litre V-8 engine, whilst the suspension geometry was lowered and track widened for more mechanical grip. A more powerful braking setup was used to cope with the extra power, and as it was targeted purely as a driver’s car, it was only available with a six-speed manual gearbox.

​

This is one of the 97 saloon variants that were produced and is likely to be one of very few specified in the rare colour of Nogaro Blue with black leather and matching Alcantara blue seat insets. It also benefits from the full S6 Plus carbon-fibre trim set, 17-inch Avus alloy wheels, electric sunroof, cell phone, and memory seats

​

This unit was given as "exchange" for advertisements of El Mundo newspaper for the President of the group to use. The marquess bought it from El Mundo with very little mileage and since then we have used it over 20 years. The engine was restored by QUattro Germany by developing and manufacturing the cylinders head and pistons for this particular unit, and the paint job has been redone and polished for having the most exquisite quality for the new owner. This is one of the most favourite and exclusive cars of the collection.
