Mazda pits 2016 MX-5 Miata against the original

Mazda has toiled admirably to keep the latest MX-5 Miata true to the spirit of the original. But just how close did the team come? To find out, the Japanese automaker brought two bookending examples of its iconic roadster down to a racetrack in Spain and put them in the hands of a couple of endurance racing drivers – Jade Paveley in the original, Owen Mildenhall in the new model. Whichever crossed the finish line first at the end of one lap would win. And because 25 years of progress wouldn't exactly make it a fair match, they gave the original a four-second head start. Watch the video above to see how it went down. 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.

2018 Mazda Miata adds a cherry on top

For 2018, Mazda is adding a number of new options that should get the attention of prospective Miata buyers, and one of them is shown above. Starting with the new model year, Mazda will offer both the usual black soft top, but also a "Dark Cherry" red top. It looks quite sharp with the silvery-blue color above, and it should be an excellent complement to the Grand Touring model's newest interior option. On the Grand Touring trim, customers can choose the reddish-brown Nappa leather interior that was first applied to the Miata RF Launch Edition. The interior package adds $300 to the top-trim Miata's price tag. There are a few other upgrades sprinkled throughout the Miata lineup. The base-level Sport models will finally get infotainment with a 7-inch screen instead of the little stereo controls mounted to the dash. The midrange Club model now gets heated cloth seats that are upgraded to heated leather units with the Brembo/BBS package, which for $3,770 adds Brembo brakes, BBS wheels, a body kit and the aforementioned seats. Another $700 nets the same package but with Recaro seats that also feature seat heaters. Along with the new features come slight price increases across the board. The base 2018 Sport trim now starts at $26,185, an increase of $395. The Club increases in price by $370 to $30,045, and the Grand Touring has the smallest change of $145 to $31,085. The first 2018 soft-top Miatas will arrive at dealerships this month, and should be available everywhere in January. Related Video: Image Credit: Mazda Mazda Convertible Performance mazda mx5
