Flat Out in a Porsche 917 - Shakedown for Rennsport Reunion V 

We live in a world of Hybrids and Race cars full of electronic aids. The sound of the 917 changing through the gears....the best sounding race car ever. Over 50yrs old....and 600+hp in a car that weighed 800kgs. 250mph rocketship. The guys who drove in that era, at night and in the rain after multiple stints were probably the best drivers ever....period.

Always will be the ultimate race car for me, flaws and all. Incredible motor music. I love F1, but I would rather watch 917s battle with Ferrari 512s any day.

Either full throttle or no nothing - that sounds terrifyingly wonderful.

The exhaust note.....I'm speechless.

A fat racing engine in a cool looking shape, straight pipes, no bullshit lab to make engines sound the way they do: Perfection.

The best sounding car engine - EVER. The best looking and most charismatic car - EVER. 917 - the ALL TIME top-dog.....!!!!

FACT - The Gulf livery makes a car faster. GOOGLE it.

the sound of the 917' is just so iconic. I remember watching the 9 hour races at Kyalami in Johannesburg when David Piper in the 917 battled against the Ferrari 512 driven by Ignazio Giunti, who set the lap record during the night. I can still recall the screaming engines of those two cars during the 1970 9 hour.

Best exhaust sounds ever made - That car is so imposing and so domineering. My era as a young boy. Good times !

My God! That car sounds great!

917 - Porsche's real Holy Grail.

the exhaust note is equal parts classic Porsche flat-6 snarl, and Lamborghini/Ferrari-esque V12 screaming. It's a sound that takes your breath away, and sounds like the car has a soul intake, rather than an air intake. the car is beautiful and terrifying at the same time.

If the sound of that engine doesn't stir your soul, you're definitely not a gearhead.

"The throttle are made for just zero and full... to hold in half is not really meant for this car" If that doesn't make a person a little nervous before driving a 917 said person is already dead.

This video leaves me wanting more! That sound was so pure. Vintage race cars are where it's at.

The sound at 4:08. Just music to my ears. The 917 is still my all time fave. Those were the days.

Listening to that thing makes me want to watch Le Mans with Steve McQueen again

Those last 30 seconds gave me the goosebumps! What a beautiful and brutal sound!

This is a video I keep coming back to time and again. The 917 was... is... the greatest race car ever made. Period. The sound of the engine stirs me to my core every time I hear it. And yes... the last few seconds of the video literally bring me to tears. I can close my eyes and simply get lost in the sound of the 917 as it screams. No car has ever sounded better, from any era. What a gift Porsche gave the motor heads of the world.

What a great race car, Performance ,sound, wonderful.

the flat 12 engine in this is SUCH a beast. The downshifts sound like mini nuclear bombs going off..sooo good

It's amazing how contemporary looking this car is all these years later. Beautiful. Thanks for sharing

At the 1971 1,00 kms of Spa-Francorchamps this car driven by Pedro Rodriguez and Jackie Oliver raced door-to-door with the # 20 car of Jo Siffert and Derek Bell over the older 14.100 km/ 8.8761 mile circuit. The # 21 won at an average speed of 249.069 kph/153.273 mph, 4 seconds ahead of the #20. The winning average at the Indy 500 that year was 253.85 kph/157.735 mph by Al Unser Sr. So they had quite the battle. Unfortunately, Pedro Rodriguez was killed at the Norisring in Germany on July11th, 1971 in a Ferrari 512M when he was ridden into a wall and the car burst in flames. Jo Siffer died in a flaming crash at Brands Hatch in a BRM F1 car on Oct. 24th, 1971. After Siffert's death, fire extinguishers and driver's air supply became mandatory and a redesign of the cars to move the fuel tank behind the drivers from along side the drivers was made. Although the numbers were used by Steve McQueen in the movie Le Mans, this car didn't appear in the movie.

The sound of the engine brings tears to my eyes and goosebumps a plenty

At 4:09, perhaps the single greatest engine sound ever!

McQueen has got to be looking down and smiling.

That upshift at 4:08 sounds exactly like the gear change in the movie Lemans - the completion of the first lap the view goes from inside the cockpit as the 917 comes down the main staight past the pits and it shifts into high - same exact sound!

50 yrs later still nothing else even close and really never will .It stands alone at the top of mountain for eternity

the last 15 seconds of the vid were great......

Wow! Just love those 917k and that flat 12 - wow! Thank you for sharing

I fell madly in love with this car in the movie Lemans!

Still one of the very best looking and sounding sportscars ever built!

Still have most of my 917 slot cars which was my fave in the 70s....The sound of that flat 12 is impossible to duplicate

Absolutely love seeing that car being driven like it was designed for!

Today the supercars haven't the essence of the old supercars and this car is the best example :)

Piëch's masterpiece. That's by far the most incredible and perfect video I've seen since years. Thank you! I need to train in GTR2 now.

This is how these old race cars need to be, still going out on the track and racing!!

such a beautiful car with a beautiful livery.

love that sound! the 917 has to be one of my favorite racing cars ever

Nothing beats a flat 12 from Porsche. The most bad ass Porsche built, in my opinion.

Holy smokes!! Never have I heard anything like this....truly incredible sound.

My favorite car of all time was in the movie LeMans. The #25 white 917 that led the race early on. Had a tail, not the same rear end as the blue and orange Gulf team cars.

Glorious. And a very pleasant commercial right in the middle. :-)

No other engine makes this kind of sound.👍🏻👍🏻❤️❤️❤️

I always enjoy those videos with someone giving a talk while driving, thus limiting his driving attention to the minimum, in a sport car, on a twisting road... and usually holding the wheel casually with a few fingers on top of that! Which removes virtually any chance to react well if an unexpected event occurs (from others or from his lack of attention). Gives a very good image of sport car drivers and an inspiring lesson to future drivers, well played.

Wow, the sound of these cars makes one eyes tear up a bit. Just soo awesome!

That sound, its literally music!

That engine sound WOW - awsom 917 flat 12

imagine if this engine /gearbox had been put in a road going car..OMG the sound!!

That sound! The sound of gods hammering at the forge.

I'm in love with that car...gotta feel for this automobile😍

The sound, the sound. Oh my...speechless.

When race cars were race cars, driven by true pilots, and not computers-on-wheels controlled by robot-drivers. Monster flat-12 sound !

What an awesome machine, and the sound! I love it.

This is a great video. Thank you!

Came back to this video just cause of the sound. And that car corners well too!

I grew up with a father who is pure Tifossi but we both love Porsche I came home from the hospital after birth in a 356. In my opinion the 917 is the most beautiful (modern) sports car ever built.

Superb exhaust note.music to ears.👍

"Zero and Full. Half way? It's not really made for this." Porsche giving us profound life advice.

Sinister, but beautiful looking car at the same time. So raw. Bone chilling cabin and a sound to match!

The exhaust is like music.

perfect! great job...just wish it was longer

My favourite Le Mans car of the lot. The noise that comes out of that flat-12 is glorious. Love the growl, even more than the noise out of an old Ferrari or Aston.

That sound!

Amazing stuff

this engine roars like a beast! awesome!

This was beautifully done.

My dads friend had one, when he'd died we were helping to clear out the garage, everybody else was to fat to get in the 917 to drive it out in to the yard, I was the only one slim enough the get in, it was the most exciting 15 seconds of my life, so loud, still have two mufflers laying around somewhere

WOW thank for the glorious audio!....oh and looks the business too

That is the most gorgeous car I have ever seen!

Damn, that thing sounds amazing!!!

Great video! Brings back many memories. The days when race car driver's drove the car's, not the car's driving the driver. I believe this was the car Steve McQueen drove in the movie Le Mans.

4:00 fechem os olhos e sintam o arrepio com esse som! espetacular !

The 917 engine was a perfect engine, it had no flaws.

Sounds just AMAZING!! :)

I'm a Ford GT40 fan but these cars are worthy of respect a truly formidable race machine.

To me this will probably always be the most beautiful racecar ever built...and I was lucky enough to see (and hear) some of them on the Nürburgring GP Track 10 years or so ago...wonderfull...

Oh! God ! The sound of those engines ..... glorious!!

What a beautiful sound

Wow a 4 minutes video that felt like 20, superb!!

0:29 My goodness, its like waking a sleeping dragon or something.

The sound of that beast just makes me happy.

damn what a monster, and sounds awesome to

That sound is just too delicious..

beauty of speed..

Good lord, what a sound that thing makes.

Got to hear this car today, man it sounds brutal

I could fall asleep each night to this noise, just dreaming of the sound over and over.

The numbers on the 917 are unreal.

That last shot with the exhaust sound.. mm mm good

Watch LeMans, the movie with Steve McQueen (1971) for more... Of this great footage and sound.

what an incredible car

that sounds amazing

the sound that thing nakes is awesome 😍😍😍👍👍👍

one of the greatest race cars of all times .... and looking at the dire electrified future it probably won't change any more

Its so fast and sooo beautiful😍😍😍

Sounds superb......!!!!!!!!!!!!!!!!!!!!!

My old boss Bruce McCaw owns one of these. When I worked for him, I drove a 964 club racer. What a sweet ride!

Oh, that glorious sound i n 3rd and 4th!!!

A binary throttle, on - off
