2019 Mazda CX-3 crossover updated with a tad more power and refinement

NEW YORK — Mazda's smallest vehicle, the CX-3 subcompact crossover, is getting a refresh for the 2019 model year. Visually, you'd be hard-pressed to tell what changed, and that's because not much did. The grille now has slats that are grouped in pairs, and the rear taillights have been redesigned. But there are a number of changes aside from visuals that separate this model from the 2018. Under the hood is still a 2.0-liter naturally aspirated four-cylinder engine. It picks up two more horsepower and pound-feet of torque for totals of 148 for each, though Mazda says that it also picks up torque across more of the rev band and gets better fuel economy. Mazda didn't have official mileage numbers, though. The CX-3 will also now come with the G-Vectoring Control system that helps improve turn-in by reducing torque and shifting weight forward. The steering and suspension have been slightly retuned, and the tires developed to better absorb bumps. Deeper inside the CX-3, several changes should make the driving experience more calm and refined. These include thicker door panels and rear door glass to make things quieter. The seats are now wider with redesigned foam cushions for greater comfort. A new integrated armrest in the center console and one in the rear seats with cup holders help the same cause. Mazda will also add faux suede trim to the cabins of CX-3s for a more premium feel. Pricing hasn't been announced for the new CX-3, but the little crossover will go on sale in late spring. So expect pricing to come soon. Fuel economy numbers will likely be available soon, too. Related Video:

Laguna Seca getting another awkward name with WeatherTech sponsorship

According to the Monterey Herald, and also reported by Autoweek, Laguna Seca is getting a new title sponsor and as a result, a new name. The track is currently known by the official name of Mazda Raceway Laguna Seca, a less-than-elegant name that goes away soon because Mazda is ending its sponsorship on March 31. The newspaper reports that the new sponsor is WeatherTech, and the new name, arriving on April 1, adds a word: WeatherTech Raceway at Laguna Seca. We're not sure why it can't simply be known as Laguna Seca, since that's the name that sticks after the sponsors disappear. And we don't know why adding a word is better. Why would you add syllables to say and letters to type (insert lazy writer joke here)? It seems that those in charge of the track are happy with the deal, though. The Monterey Herald reports the deal is for five years of sponsorship at a cost of $5 million and that it's about two-thirds of what Mazda was paying. But the newspaper also reports that the track won't be providing the same track access that Mazda needed, and it may attract other automakers to the track when the track's name isn't partly that of a competitor.

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.
