Mazda CX-5 in auto-brake accident on Japanese test drive

As we slowly march towards a world where our cars will drive for us, there will be mishaps. Systems will act up, not behave has intended or we'll simply forget to turn them on. We all remember when Volvo tested the S60's City Safety system. Now Mazda has had an issue of its own.
During a test of a Mazda CX-5's Smart City Brake Support on a dealership lot in Japan, a prospective customer and a dealership employee were injured when they hit a urethane barrier used for testing the system. According to Bloomberg, which spoke with the Saitama Prefectural Police, the impact with the barrier left the customer with an injured neck while the dealership employee suffered a fractured arm. Considering the injuries, we imagine this wasn't a small barrier.
"For any safety function, it's impossible to be 100-percent free of accidents. These technical functions aren't always the easiest to understand," IHS Automotive auto parts analyst, Hiroshi Ataka told Bloomberg.

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.

Mazda hands over first factory-restored Miata

In August 2017, Mazda announced that it will be offering factory quality restoration work for the original, NA body Mazda MX-5 Miata introduced in 1989. The program also included parts support, as Mazda wants to underline how much the original Miata still means to it. The program was launched with exemplary work carried out on a Miata owned by Mazda, but the first customer car has now been finished. The first car was picked from 600 applications sent to Mazda. Out of all these cars needing factory certified work, the 1992 British Racing Green V-Special owned by retired tomato farmer Keiji Nishimoto was chosen to be the first. The Eunos-badged limited-edition car was bought new by Nishimoto, and he told Mazda the car had been instrumental in creating some wonderful road-trip memories. The V-Special edition came in a British roadster-style color combination: "Neo" green over tan leather, complete with a retro-style Nardi wood wheel. The car also has a front strut bar and a limited-slip differential. Nishimoto had already been planning to get his car restored, but getting it done by Mazda during the summer was even better. The car was finished in August, and it was officially handed over to its owner in September. To have owned and enjoyed a car for a quarter-century and getting a chance to experience it in as-new condition again must be a fantastic experience. Nishimoto says the car is now good for another 25 years of driving. For the time being, the TUV Rheinland certified restoration program is only available for Japanese customers. But since a large percentage of first-generation Miatas are still on the road, and a large percentage of those will need bodywork done in all the usual places, we would happily see Mazda reach out to European and American customers as well.
