Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.

Driving a $500 junker in a 500-mile off-road rally race | 'The List' #0500

Jessi and Patrick have done some insane rally races on "The List," but in an effort to continually out-do themselves, this might be the craziest yet. It's called the Gambler 500, and the idea is that 2,000-plus participants take $500 cars and drive them 500 miles across Oregon, mostly off-road. It's a maniacal mishmash of cars with not enough doors, too many doors, airplane wings strapped to the tops, graffiti'd cartoons on the hoods, stuffed animals hanging out the windows — you get the idea. Our hosts start the race with an absolutely epic Mazda Miata sitting atop super swampers. It didn't have a top, but have no fear because it had a roll cage, so ... that's better? Unfortunately though, they didn't have time to customize the car fully to their liking before the race, so the first stop after the starting gun was naturally a garage sale for some knickknacks to give the car a little more flair. One of the defining aspects of the Gambler 500 is having the most obnoxious, bonkers car possible, and the old Miata needed a bit of a kick in the ass. Thankfully, the crew found the largest teddy bear in existence, strapped that bad boy to the roll cage, and they were on their way. There are a few routes you can choose to take in the Gambler 500, and our crew chose the most challenging, called "The Devil's Butthole." A hilarious name for an outrageously fun route, it's definitely not one that many Miatas have likely tackled. And therein lies the gamble: Will they make it to the end? As always, you'll have to watch the episode above to find out.
