2018 Mazda CX-5 teased ahead of LA reveal

While it will make its full debut at the LA Auto Show, Mazda released a teaser of the new CX-5 ahead of time. Like so many other teasers, the car is obscured by low light, but we can make out some significant details. For one, it appears that Mazda has toned down the muscular curves of the current CX-5's front fenders. In fact, many of the crisp creases of the current model have been softened on this new version. Below you can see a brighter version of the teaser alongside an image of the current model. The greenhouse also appears lower and longer than the current model, and it's highlighted by a chrome strip running from the A-pillar back to the roof. Where it terminates also seems to suggest this CX-5 could have the "floating" roof look that's so popular now. However, when comparing the teaser image with recent spy photos, it could just as easily have a more traditional rear pillar and roof design. Those same spy photos also reveal that the new CX-5 will get a more aggressive, concave grille with a mesh insert. This image is all Mazda has revealed of the new crossover so far, so we'll have to wait until the reveal on November 16 for all the details. Related Video:

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.

Tech of the Year special, plus we drive the hydrogen Mirai and more | Autoblog Podcast #809

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick and Road Test Editor Zac Palmer. They kick the discussion off by talking about what they've been driving as of late, including the Toyota Mirai, Dodge Hornet, Alfa Romeo Tonale and a trio of subcompact SUVs. After that, they dive into a discussion about the 2023 Autoblog Technology of the Year award winner, which is Mercedes-Benz's Dolby Atmos Spatial Audio. Once they wrap up that segment, we get to hear the crew's latest Cybertruck takes from before the big reveal. Finally, the show wraps up with a fun Spend My Money segment.
