Mazda's new turbo four fits in both the 6 and the 3

Despite the size differences, the Mazda CX-9 shares a lot with its smaller car-based siblings, the Mazda6 and Mazda3. That could allow Mazda to slot its full-sizer's new 2.5-liter, turbocharged four-cylinder engine under the hood of its smaller offerings. Pardon us while we do a happy dance. "[The 2.5-liter turbo] fits in a lot of our cars, and where we're actually going to put it is another question," Mazda North America vehicle development engineer Dave Coleman told Australia's Car Advice. Coleman specified that the turbocharged engine will fit in all the same applications that can accommodate the company's 2.5-liter gas and diesel engines. "Basically, that big space we used for the bundle of snakes exhaust manifold, the turbo is in that space too. They're all packaged to occupy the same space. It's exactly the same clearance as the exhaust manifold of the other engines." This kind of logic – if Engine A is the same size as Engine B, then both should fit in Car C – is what's lead us to imagine a turbocharged Mazda6 since the new engine was announced. In short, it's great news. Mazda's 2.5-liter turbo is a hell of an engine in the CX-9, and it's hard to imagine it'd be worse in a lighter vehicle. But just because it works from an engineering standpoint doesn't mean it's going to happen. At least, not soon. "It fits. I'm not a product planner so I don't get to make that call," Coleman told Car Advice. "It's up to the product planners to decide what they're going to put it in." The most obvious application for a turbocharged engine in the 3 or 6 is as a reborn Mazdaspeed model. But don't get too excited – Coleman said Mazda hasn't even gotten as far as building an engineering prototype with this engine. We're still firmly at the theoretical stage. And that's bad news, because it gels with what we've been reporting – that Mazda will wait a generation for future Mazdaspeed models. We just stopped doing our happy dance. Related Video:

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.

Long Road Racing will build you the Miata that Mazda won't

One of the frustrating things about new cars today is that many features are exclusive to this trim level, or that package. Even the enthusiast-friendly Miata has many restrictions how you can configure one, which can make choosing one a bit tricky. You can't have the cheapest one or the leather-clad one with a limited slip differential, for example. And adding aftermarket parts on your own runs the risk of voiding your warranty. Long Road Racing, however, has a possible solution for creating the ideal, warranty-covered Miata. You may not be familiar with Long Road Racing, but you probably heard about one of its most-publicized products, the MX-5 Cup car. The car was developed by Mazda with the intention of creating a global spec series, and Mazda reports that about 140 of the cars have been sold so far. Every single one of those cars went to Long Road Racing to be specced out for racing before reaching their customers. So the company is familiar with the car, and has applied its expertise to its "Ultimate MX-5" program. The way the program works is, once you've purchased a 2016 or 2017 Miata, you can send it to the company to have it customized to your needs. The company has an extensive list of parts to choose from, all of which have been selected by the company to work well together. But if you need something outside of its offerings, or just need help choosing from the list, you can get in touch with the company to discuss how best to achieve your goals. Long Road Racing will also customize any trim level of Miata, and can even create a Miata Mazda didn't offer. For instance, you could have a Grand Touring with the leather interior, but also with the limited-slip differential and Brembo brakes from the Club model. All of these parts are fully warrantied by Long Road Racing for the length of the OEM warranty, and they don't void the factory warranty. We had the opportunity to try out a car customized by Long Road Racing at the M1 Concourse track in Pontiac, Mich. The car was there to sample alongside some of the MX-5 Cup cars as well as several of Mazda's stock road cars to drive on course. The road-going Long car started as a Grand Touring model, and it retains its heated leather seats and automatic climate control.
