What a special car. It is so long, and looks like a cockpit off an airplane, or a large shoe. Very good to know that the car has not vanished, and is in a museum.
Thanks! Never heard of that one! Noticed that it was Right Hand drive, which I wouldn't have expected.

This is one funky looking ride! Sure, I get the aerodynamics, but it looks backwards to me. The front end should be the back and vice-versa. Not a pretty car, and the wheels don't help. Still pretty cool!
He is right about Tatra,. The backbone frame and swing axles rear mounted aircooled engine streamline body design were all Tatra engineering. Porsche was familiar with the Tatra designs and knew Treblinka the chief designer. He actually got some of the ideas a little ahead of the Natzi invasion of Czechoslovakia.
Very cool indeed ! As a hobby pilot I appreciate aerodynamic bodies. However, my impression is, people want to have a big car, biggest as possible, many cubic meters of volume. They don´t really care for the cw-factor or fuel consumption or weight of a car.

Nice video, yet it's wrong. Paul Jaray was building streamliners in 1919, you can find pics of his cars from 1920. He patented these concepts, he was originally a zeppelin designer. Tatra, in the Czech republic, used these principles until it was invaded by Germany in the late 1930s. The production cars were the Tatra T77, T 87, T 97, and the T 600. This technology was stolen and used to make the first beetle. The Tatra T 600 was the Beetle's inspiration and would have made a much better choice than the German version. Volkswagen got sued, and paid a huge yet undisclosed amount of money to Tatra in 1965 for theft of technology. You all need to do a better job researching before making videos.
It been a while since I've been interested in vintage machinery, yet this is the first time I heard of ths one. What is a bit weird is that the wheels look very non-aerodynamic on many pictures, in one shot it even sports chunky off-road tires. It probably has been through a lot of modifications over its career.
My car has a drag coefficient of 0.30 (1986 Nissan 300zx with a 1987 revised front end swap with side skirts and rear-deck spoiler. Albeit much more advanced and aided by early computer models it's still interesting to understand how designers achieved those numbers. Cars today are nowhere near as aerodynamically efficiant.
I don't think they were going for land speed records or building it light like hpvs. This is slab sided but no more so than other vehicles of the 1920s and early 30s
Raindrops are not tear shaped when falling through the air. They are approximately round, but he got the drag coefficient down anyway. Thanks for posting
Considering that Persu did his work 30 years before computers were available, and computers sophisticated enough to run complex simulations were another 2 decades away, I think he did alright. I wonder how good YOU are with a slide rule. Also, the ultra high speed cameras necessary to see the true shape of raindrops were developed to film nuclear weapons tests and aerospace test flights... during the '50s. Next, you'll be criticizing Archimedes, for not discovering fractals!

I didn't mean to offend anyone, I treat all brands equally. When I created the title for the video, I used the information from the text I was working on, in the text there were comparisons with Tesla. It's just a title.
The shapes that allow aerodynamic efficiency can be quite counter intuitive. Having spent time in the MIRA wind tunnel I can confirm this phenomenon. I can understand your “ugly” comment, but the laws of physics cannot be denied.
I call bs on the aerodynamic CD figures. There is no way that vehicle, with that front end is cutting better drag figures than a Tesla, there's too much frontal area, and it's too upright to better the Tesla's figures.
It works because it's a copy of a water drop, the most aerodynamic shape there is. Blunt nose, tapering body. Mercedes developed a van based on a water drop but as it didn't offer the carrying capacity of a regular van so they looked to nature and found that the Puffer fish was just right, sort of blunt nosed with rounded corners, flat sides and a narrow tail. Their prototype came out with a very low coefficient of drag but the production model got more space with a small sacrifice of efficiency. Most cars are actually backwards. Thin fronts and bigger, blunter backs causes vortexes to form at the rear causing drag.
Tapering tails reduce departing turbulence. Not have to pull a huge low pressure area along behind you reduces drag more than having a pointy nose does.

Fantastic aerodynamic design from 100 years ago!

Was that long space behind the cabin occupied by the engine? Or, was it more of a truck?

How many persons this car can carry?
two
One and a half.

No tech specs about the engine, gearbox, total weight, fuel consumption etc.?
My guess is an air-cooled VW engine, with a standard gearbox.

The front end is definitely Heinkel Bubblecar looking.

I apologize for everything I ever said about Citroen's ......
Looks to be a very narrow vehicle. It may be a very aerodynamic design, but I have questions about its dynamic stability.m
Wow that would be interesting to see a test drive around the racetrack
It looks like a VW beetle, a French DCV and the alien from the movie "Alien" had a child.

It has to be commercially viable…
Járay Pál 3-4 évvel megelőzte. De ez is figyelemre méltó.
The problem with so-called 'perfect' aerodynamics is crosswind susceptibility.
@campbellpaul This one looks not too bad from that point of view. It also ran for 120,000 km.
@@campbellpaul It "looks" like it wouldn't have any issues with crosswinds. I could be wrong, but the long tail should help there.
i think the concept of aerodynamics includes wind
A crosswind wouldnt slow you down would it?

my 25 year old honda insight has the same drag coefficient of a tesla, not exactly breaking any records.
There were spaceships before ww1?
You say his name completely wrong. It sounds something like aww-relle-perr-shoe, with the 'aww' pronounced more like 'awl' without the l.

it's based on a raindrop, not a foot.
Raindrops are actually flat because the wind flattens them
Tapering tails reduce departing turbulence. Not have to pull a huge low pressure area along behind you reduces drag more than having a pointy nose does.
