This Porsche had a chassis that was inflated with nitrogen. It was incredibly light, which was down to some ingenious design tricks to take weight saving to the next level.
The chassis was made of extremely thin aluminium tubes, and used the nitrogen in a really interesting way - but more on that later. Porsche used exotic materials and even filled some of the other chassis tubes with oil, saving the weight of an additional oil tank and pipes.
Weighing only 895kg and having nearly 1000bhp, it was an absolute rocket-ship.

It was 30mph quicker on the straights than anything else and absolutely dominated at Le Mans. Well, whilst it was on the tarmac. It was a real handful to drive and lead to some terrible accidents.
But Porsche managed to fix these strange problems by actually examining the pattern of splatted flies on the car.
It’s the Porsche 917, one of the most iconic cars in racing. It used some of the most advanced engineering techniques of its time and was Porsche’s first car to win Le Mans.
And with 19 overall wins and 108 class victories to their name, they are now the most successful manufacturer ever to race at Le Mans.
So what clever engineering tricks did Porsche use to forge new limits and make one of the greatest race cars ever?

    Interestingly enough, VW AG wanted Audi to stop winning Le Mans so Porsche (another VWAG company) could have a chance again, since they are the sports car brand. If it wasn't for that, Audi would have most likely had won all races from 2015+ and had the most wins in Le Mans history.

    I know the Ford GT40 had it in the front (the Mk.IV in the rear) and the Porsche 917 at the rear, on top of the gearbox : a SPARE WHEEL. My question: was that in the rules back then? Or did teams/manufaturers only put that in on long circuits like Le Mans, Nordschleiffe, etc. ?

    The car at the pinnacle of the most awesome era of endurance racing. A combination of innovation, skill, gumption, and sheer speed not seen before or since. Footage of the Gulf 917s braking in the rain in the movie Le Mans shows just how on the edge things were. Also had the last word in the Can-Am series.

    Why not use a vacuum instead of Nitrogen? You could still tell if you've got any cracks with a vacuum gauge, but it'd be lighter than gas-filled. Right?

    Nitrogen was NOT used to make the car lighter. Pressurized gas was used to test cracks in magnesium. so the oil would not leak out. Wyer replaced system with normal oil tubes to add reliability, because a small crack would finish the race

Turns out, they were hiding a Nitrous oxide system in their sealed chassis. Must have had an excellent fab shop on their side.

    I'm surprised given how pedantic they were about weight that they didn't just use helium. Would have saved a few hundred grams lol. They made the shift handle out of balsa wood ffs to save several grams. I'm surprised they didn't make the driver eat food that wasn't as dense for a few days prior to the race, make em shave top to bottom for weight reduction, only hire people who have had an appendectomy to drive, and wear a race suit one size too small something hahaha. This was literally the last word in weight saving. The more you read about it the more you realize how obsessed they were with saving weight. So much so they forgot to make sure they had air going over the fucking rear wing. Absolutely amazing machine though.

    Scott: That Porsche nitrogen or gas filled space frame was not such an original idea. My friend has a 1968 Czechoslovakian Zlin Z-526F tandem seat, aerobatic trainer with a very similar system. There is a pressure gauge inside the cockpit to detect any cracks in the chrome-moly steel frame. But unlike the Porsche 917 it was not made from "unobtainium" as the late Mark Donohue once quipped when asked what the frame was made from.
