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.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

2020 Mazda CX-9 gets more torque and second-row captain's chairs

The 2020 Mazda CX-9 is here, and it’s even more enticing than the 2019 model year SUV. ItÂ’s not a full redesign, but Mazda shook up the features list to make it more competitive with other three-row crossovers. Most notable (arguably) of all changes comes from a small increase in torque — the 2.5-liter turbocharged four-cylinder gets bumped from 310 pound-feet of torque to 320 pound-feet. Horsepower remains the same at 250 horses. Those figures are only applicable when using 93 octane fuel. They go down to 227 horsepower and 310 pound-feet of torque when on 87. Another new feature is an off-road traction assist button, replacing the traction control button. This new feature is meant to help when navigating rougher terrain. HereÂ’s how Mazda describes its function: “When the diagonal wheels lose traction, off-road traction assist will stop reducing the engine torque and increases the brake force on the wheels without traction. This transfers power to the wheels still on the ground to help allow the vehicle to regain traction and continue the drive.” WeÂ’ll be interested to see how this helps the CX-9 on a snowy Michigan winter day soon. The number of standard features on the base Sport trim is up, too. Now all CX-9s get heated front seats, a power driverÂ’s seat, rain-sensing windshield wipers, heated outside mirrors and auto high-beams. Additionally, Mazda made its full suite of i-Activsense safety features standard. This includes adaptive cruise control, lane-keep assist and other driver assistance niceties. Mazda is also adopting the new key fob design of the Mazda3 for the CX-9. Optional on the Touring and Grand Touring are second-row captainÂ’s chairs. Previously, Mazda only offered bench style seating for the CX-9, so this addition could be a huge turn-on for some folks in this segment. The chairs have armrests, and the lack of a center pull-down means Mazda had to redesign its cupholder layout in back. In CX-9s equipped with the chairs, the cup holders and USB ports are now integrated into the backside of the front center console. If you opt for the captainÂ’s chairs in the Grand Touring or Signature trims, the seats are heated.  Pricing does increase a fair amount for the 2020 CX-9. A base front-wheel drive Sport is now priced at $34,835 including destination, a $1,510 increase from last yearÂ’s base price. The top of the range only got $750 more expensive, though, as the Signature starts at $47,160.
