Why you absolutely need to take your Miata to a track

Our long-term 2016 Mazda MX-5 Miata entertained us all summer, but we couldn't let the good weather pass without taking a trip to a race track. So we headed to GingerMan Raceway on the other side of Michigan to give it some exercise. It's there that I fell deeper in love with our little silver-white Club and immediately regretted not taking it to the track every single weekend prior. I make a very simple case in the video above: Miatas belong on the track. They're made for it, especially our ND Club, the most track-friendly version Mazda currently makes. The Miata is also a wonderful tool for those learning to drive in these conditions. It gives you good feedback, there isn't too much power available, but the engine's output is plenty to make things entertaining. It's also one of the more balanced performance cars you can buy today and doesn't rely on fancy electronics to go faster – it's a nearly direct connection between you and the car, with no weird intermediaries or adjustable elements. This is really the simplest form of fun. To sum up: If you have a Miata, take it to a track. If you don't have a Miata, go buy one. Watch the video again if you're not convinced. Related Video:

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Xcar tries to figure out what makes the Miata so great

Over the past 25 years and 3 model generations, the Mazda MX-5 Miata has shown that you don't have to be the best to be a massive success. The little, Japanese roadster has never been the absolute peak of automotive performance, but it's precise handling, good reliability and frugal running costs have helped make it a star. Autoblog recently tried to give you the experience of driving one on video, and now Xcar Films has made its own in an attempt to show what makes this droptop an icon.
As Xcar puts it, the Miata isn't the world's best sports car, but it is the world's favorite. When they were originally designing the roadster, Mazda's engineers took everything that made British droptops from the '60s great, and junked all of the stuff that made them a terror to own. The result was a car that would start up everyday with no fuss and get drivers wherever they needed to go with a huge grin on their face.
The fourth-generation Miata is imminently on the way for its September 3 unveiling, and the very early rumors indicate that Mazda doesn't plan to rock the boat too much with the latest one. It supposedly rides on a longer wheelbase and wider track but with the weight trimmed by over 200 pounds. Check out Xcar's video for a primer on MX-5 history and why the automotive world loves this little roadster.
