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.

2020 Mazda3 Review & Buying Guide | The connoisseur's choice

Completely redesigned last year, the 2020 Mazda3 pretty much carries over, continuing to be the connoisseur's choice for a compact car. For starters, its elegant sedan and unique hatchback body styles are considerably more stylish than expected for this segment. Park it next to a similarly priced Honda Civic or Toyota Corolla and people are likely to think you paid far more than you did. The same goes for the cabin, which is functional yet stylishly minimalist (if a bit cramped). Then there's the driving experience, which continues to delight those who value sharp responses and a driver-focused character. The switch to a less sophisticated rear suspension for this latest generation has dulled some of its corner-taking capability at the limit, but that's a low-percentile complaint. The bigger dynamic beef is perhaps that Mazda doesn't offer a hotter version in the vein of the Civic Si or VW GTI. Yet, that falls under the category of "wishes" not "problems," which the 2020 Mazda3 has scarcely few. Perhaps it won't be for everyone in the market for a compact car, but everyone should at least consider it.   What's new for 2020? After being completely redesigned last year, updates are light for 2020. The base trim level now comes standard with the Mazda i-Activsense suite of accident avoidance tech and driver aids that continue to be standard on every other trim level. 2019 Mazda3 AWD View 33 Photos What's the interior and in-car technology like? The interior quite simply makes you go "wow." A Honda Civic or Toyota Corolla, which are actually quite nice, look and feel like they should cost substantially less – especially when comparing top trim levels. Whatever trim level of 3 youÂ’re considering, however, the key to its wow factor is how the MazdaÂ’s design removes visual clutter by reducing switchgear and effectively hiding air vents and door handles. It just looks special. It's also functional. The steering wheel, which looks sensational, is an absolute treat to hold. There's considerable center console space and Mazda's tech interface, which had lagged behind its competition due to key usability issues, has been cleaned up. The dashtop screen is large and easy to see. The knob that controls it is large, not unlike BMW's iDrive, and ergonomically placed on the center console. It's not a touchscreen, though, as Mazda engineers determined that hunting for touch-operating icons can be distracting.
