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.

Mazda2 nets Japan Car of the Year, Cherokee first US model to ever crack top 10

The 2015 Mazda2 is quite high up on our must-drive list. Yes, the teeny, tiny successor to the 100-horsepower five-door is worth getting excited over, largely because the previous generation was one of the absolute best smiles-per-dollar values on the market.
While we eagerly await for our opportunity to take to the 2's helm, our expectations of the new car have just been heightened thanks to its win in Japan's Car of the Year competition. Called "Demio" in the land of the rising sun, Japanese journalists handed out Mazda's second COTY award since the CX-5 took the title in 2012.
In more surprising news, the new Jeep Cherokee has made the list of 10 Best Cars in Japan. The Jeep's triumph marks the first time an American car has cracked the top ten, finishing eighth. It's not, however, the first Fiat Chrysler vehicle to snag the title, following in the footsteps of the Alfa Romeo Giulietta and Fiat Panda. Still, the fact that an American brand can make such impressive inroads into the traditionally tough-to-crack Japanese market is a seriously big deal.

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:
