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.

2019 Mazda CX-9 gets Apple CarPlay, Android Auto, slightly higher price

Now that Mazda finally launched Apple CarPlay and Android Auto in the 2018 Mazda6, the company isn't wasting time proliferating the infotainment upgrade to the rest of the lineup. The next on the list is the 2019 Mazda CX-9 large family crossover SUV. It's standard on Touring, Grand Touring, and Signature trims. But if you choose to go with the most affordable Sport trim, it's an option. Up-to-date infotainment isn't the only upgrade to the new CX-9. Every version receives thicker floor mats and a thicker headliner meant to further reduce the amount of noise that enters the cabin. The transmission is also retuned, and Mazda says the new tuning is meant to provide a smoother, quieter driving experience. We'll be interested to see how effective it is the next time we have a CX-9 in the office. Each individual trim level also gets some new options and features. The base Sport trim has a Sport Package available that adds heated front seats, a power driver's seat, heated mirrors, lane-keep assist and departure warning, adaptive cruise control and automatic emergency braking. The package rings in at $1,290. The Touring trim gets the fewest new features with its only new addition, besides the infotainment, being a frameless rearview mirror. The Grand Touring trim receives the 7-inch screen in the instrument panel also found in the Mazda6, along with new power side mirrors and a 360-degree camera system. The top-level Signature trim gets new badges, rosewood interior trim, and accent lighting in the grille and around the shifter. With all these new features come new prices, which are naturally higher than last year's. The smallest price increase is between base Sport models. The new one is just $150 more than the old one. The largest increase comes with the Signature trim, which now costs $1,050 more than the 2018 model. You can see the entire price list and changes below. Trim 2019 2018 Sport (FWD) $33,275 $33,125 Touring (FWD) $36,325 $35,955 Grand Touring (FWD) $41,835 $41,465 Signature (AWD-only) $46,360 $45,310 AWD Option (Sport-Grand Touring) $1,800 $1,800 Related Video:

Mazda reports highest profits in its 94-year history

We may only be a third of the way through 2014, but for Japanese companies, March 31 marked the end of fiscal 2014, and it was a banner financial year for Mazda's global operations. The Japanese independent saw its highest global operating profits in its nearly 100-year history. Its global operating profits were up a huge 238 percent. Yes, a 238 percent increase over 2012 to 1.36 billion euros ($1.88 billion), eclipsing the brand's previous best year, 2008, by 12 percent. Net earnings, revenue and global sales volume also saw increases over the last fiscal year.
What's most impressive, though, is where Mazda saw improvement. The notoriously rough European market was rather kind to the Zoom-Zoom brand, where sales increased 25 percent to 163,000 units. That figure was bolstered by a 35-percent sales increase in Great Britain and a 20-percent jump in Germany, Europe's two largest markets. Japanese sales, meanwhile, were up a respectable 13 percent, to 244,000 units. In China, Mazda saw a 12 percent bump.
Notice we aren't talking about North American sales? That's because Mazda only saw a moderate, five-percent gain in the New World, with sales climbing to 391,000 units in the US, Canada and Mexico. This is particularly disappointing considering Mazda has launched three critically acclaimed products (CX-5, Mazda6 and most recently, Mazda3) for the North American market over the past two fiscal years. Still, it isn't a particular reason to be concerned, as IHS industry analyst Stephanie Brinley notes. "Five percent isn't terrible," Brinley told Autoblog, saying that Mazda should see a bump in 2014 as the Mazda3 picks up steam.
