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.

Mazda6 sees gains in ugly month for midsize sedans

Though June overall wasn't a terrible month for automaker sales, at least for the most part, it was pretty hideous for midsize family sedans. Basically every single model in the segment saw declining numbers including the Subaru Legacy, Nissan Altima, Ford Fusion, Volkswagen Passat, and even perennial volume sellers such as the Honda Accord and Toyota Camry. All of these cars are down in year-to-date numbers, too. But there's one bright spot, and it comes from Mazda. Mazda reports that the Mazda6 actually had a really good month. It sold 3,204 examples of the family sedan in June 2018, compared with 2,360 in June of last year. That's a nearly 36 percent increase month-over-month. It was also enough to bump Mazda6 sales for 2018 ahead of 2017's numbers through June. Those numbers also put the Mazda6 ahead of the Volkswagen Passat for June, and just 20 vehicles shy of the Subaru Legacy. Admittedly, these are still small numbers all around. In the same month, Honda sold over 26,000 Accords, and Toyota sold about 27,000 Camrys. Sales of Mazda's other vehicles also indicate that crossovers really are the new hotness. The CX-5 sold a whopping (relatively) 12,710 units. The CX-3 and CX-9 sold about 2,300 examples each, which is below both Mazda3 and Mazda6, but both crossovers gained more this month and over the year than both cars. Mazda3 is actually down this month and overall. All of this also seems to give some credence to Ford's decision to move away from traditional sedans. Still, for fans of more conventional cars, it's a bit heartening to see that more niche players can find some success with the design. We're also pleased to see such an excellent sedan recognized with actual buyers. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Full 2016 Mazda MX-5 Miata pricing released

Take heart, roadster fans. The first 2016 Mazda MX-5 Miatas due for the US are now in production. To go along with that milestone, the Japanese automaker has finally released full pricing for the fourth-generation Miata. As previously revealed, the 2016 Miata in the base Sport trim starts at $24,915 (plus $820 destination), and for that outlay buyers get a 2.0-liter four-cylinder making 155 horsepower and 148 pound-feet of torque that's matched to a six-speed manual. The convertible comes standard with features like LED lighting and a Bluetooth-equipped audio system. For $1,075 more on all models, customers can spec a six-speed automatic gearbox, and keyless entry is another $130 but standard with the auto 'box. One rung up is the Club trim for $28,600, and it improves things with 17-inch wheels, a more aggressive body kit and a seven-inch touchscreen infotainment system. Order the manual trans, and the roadster gets a limited-slip differential, Bilstein dampers and a shock-tower brace. There's also a $3,400 package to make this version of the convertible even sportier with 17-inch BBS wheels, Brembo front brakes, side sill extensions and a rear bumper skirt. Among the regular trims, the top rung is the Grand Touring for $30,065 that adds luxuries like heated, leather seats, automatic climate control, rain-sensing wipers, and adaptive headlights. Mazda's i-Activesense is also standard and includes blind spot monitoring, rear cross-traffic alert and lane-departure warning. Finally, there's the Launch Edition, which is limited to 1,000 units, and it sells for $30,495 (or $31,570 for an automatic). All of them come in an exclusive combo of Soul Red with Sport Tan leather, and buyers get all of the Grand Touring's kit, plus standard keyless entry. The order site for these special roadsters opens on May 5, but hopefuls can pre-register now for a reminder. The first 2016 Miatas should hit dealers in late summer. That should provide some time for top down driving fun before it gets too cold.
