From 19Bozzy92, it is the Porsche 956, the first ever, original Group C prototype that debuted in 1982. This particular car being focused on is a customer model that raced during the 1983 and ’84 seasons.
The 956 in this video is chassis 956-101 which is a very important Porsche: the first ever customer-delivered Porsche 956 Group C car. It was sold in 1983 to Kremer Racing and fielded in both the 1983 and 1984 World Endurance Championships. It also took part in two 24h Le Mans races, ending in 3rd position in the 1983 edition driven by Mario Andretti, Michael Andretti and Philippe Alliot with the blue Kenwood livery you see in this video.
The car has been restored in its 1983 Le Mans specs, featuring the low drag/long tail rear aero package typically used by Porsche and customer teams for the French race and its long straights. Even if you all know the typical big and tall rear wing which has always characterized both 956 and 962, that’s the short tail/high downforce version of both cars. The ‘Long Tail’ term, ‘Langheck’ in German, comes from the fact that the bodywork portion below the rear wing is way longer than the high downforce version, even if the lenght of the car is probably the same, since the short tail’s rear wing extends far behind the final rear portion of the body.
Since I’ve mentioned the 962, it’s always a bit difficult to understand if you have a 956 or a 962 in front of your eyes, due to the extreme similarity the two cars shares. The most recent 962s are quite easily distinguished, sometimes due to the headlights and generally by the wing (the one detached from the body, in particular, like at 4:24 of the white ‘Le Mans’ 962). The livery can also help too, but some older 962s may still feature the high downforce or the long tail setup and wing taken from the 956, making them looking exactly the same. Apart for what is the main reason the 962 exists: the longer wheelbase that was necessary for Porsche to comply with IMSA safety rules (in the 956 the driver’s feet were ahead of the front axle center line, being too dangerous for the driver in case of a crash). But if you don’t have both the 956 and the 962 close to each other, it’s still hard to spot those extra centimeters. The best method is to check the gap between the door and the front wheel arch, which translates into that blue space between the white square with the number and the actual wheel arch in this case. As you can spot, that blue area is really short on the 956, just the direction indicator light fit inside that space. On the 962 the area would have been of around 25/30cm wider and that’s very noticeable even from the grandstands because there’s a lot more space between the direction indicator light and the front wheel arches.
Here’s a couple of pictures to better visualize it (look at the direction indicator): – 956 (Long Tail):

The Porsche 956 is powered by the Type 935/76 2.65-litre, twin-turbo flat-6 engine that was able to produce up to 630bhp at 8,200rpm in the 1984 956 ‘B’ evolution version.
