Sportscar endurance racing is one of the most versatile form of motor sports out there. It can contain both blazing, young guns and veteran hounds within the same team, often in the same car. Such as Senna and Pescarolo.

It happens so that in 1984 the Nürburgring was converted into the sprint track people know today mostly of Formula One and DTM fame. While F1 left the track for the Hockenheimring following Niki Lauda's accident, only to return to the new, safety-improved, shortened and completely different track in every single way. Sporstcar racing was still big at the old 'Ring - of which the flamboyant and fearless 1982 F1 Champion Keke Rosberg famously said it (i.e. the 1983 race) being one of the maddest thing he had ever taken part in, even the 1000km endurance race was moved to the new circuit for 1984.

After a blistering victory with a stock Mercedes in a champion-studded race at the very same track two months prior and a mighty battle for the first place In Monaco right after that, rising F1-star Ayrton Senna won a seat for the 1984 edition alongside sports car legend Henri Pescarolo and then-Toleman-F1-team-mate Stefan Johansson.

Joest Racing - now known as an associate to the Audi LMP1 program since its beginnings - was one of the strongest Porsche 956 running teams at the time - as most teams did, so there was a genuine race for the top positions.

The trio finished 2 and 3rd down the fleet of Porsches (diversified by a single Lancia at 3rd position) in P8 overall.

Yes, you are right ... it was in 1984 but I can't changed that now otherwise people can't find the car.
Link is placed at some places, anyway thanks for pointing that.

No problem. In fact at that time the cars from one year were very similar to the one from previous year. they were times where there was some stability on the FIA regulations were very stable. Therefore the developments costs were also reduced and the races were spectacular: Private cars were so good as the official cars. The races were very competitive and had lots of spectators.
