The rotary engine that Mazda used in the beloved RX-7 and RX-8 doesn’t work like other engines. This episode of Science Garage explains what’s going on inside the magic triangle that gets you all that high revving action that rotary drivers love! People who know them love them AND hate them. From rotors and apex seals to housings and E-shafts, you’ll learn about the Wankel Rotary Engine, and HOW IT WORKS!
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.
Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

No why because times where different then and I am sure billet blocks and heads didn't come into existence. There is intellectual aptitude yes but pure intellect alone does not subsitute for pratically reality of manifesting things. You need skill and intellect to make something manifest. In the case with these guys. They are keeping this relic of mechincal engineering around and are improving upon it as we speak and breath. So yeah...do not doubt that something is assumingly futile because it has failed in the past.

Red Valkyrie Haven't watch Wangan Midnight, and I personally prefer skills and techniques rather than raw power. But I heard of a tale of the crazed driver of the mountain passes.

I've heard that story many times. And for some reason, whenever it gets to the point of him lighting his cigarette, an odd piece if music begins playing. At first it sounds all silly and fun, but then it suddenly turns all serious. And just as the verse is about to kick in, you can here a different middle-aged man, possibly a friend of the crazed driver, shout at the top of his lungs for someone to save him. And then all sounds are cut, replaced by the clear sound of tires screeching. Gives me goosebumps whenever I hear it.

Hey Donut Media, can Bart make a video about Toque vectoring? Big fan. Appreciate your vids

[@user-cl2ls7kz7o]

Cool concept. Aero guys love it because it's light compact and puts out "tons" of power. But in reality the three stoke design doest let itself well to reliability, efficiency (because the cuin is a lot bigger than they claim), and if you turbo anything it can have great power.

Vadim Blyat Doesn't necessarily has to be old, RX-8 exists.

[@justaguynamedmax8207]

That One Guy rx8? You mean that car you can't even find on the road anymore because they all had shit motors?

[@tyson8254]

Either that or people don't know how to lubricate. I have a 13b-MSP in my RX-7 GSL.

[@Rodrox239]

ak operator no, he means that car that won 4 times the drift world contest

[@justaguynamedmax8207]

Rodrigo Mangas that means nothing. Drifting is for 14 year Olds and vaping douch bags.
