Mazda CX-3 almost ready for LA Show

The Mazda CX-3 is just days away from its unveiling at the 2014 Los Angeles Auto Show, but elsewhere in the world, the Japanese brand still has the compact crossover disguised for testing. These spy shots aren't too camouflaged though, and when combined with the previous teaser image, they give a pretty clear idea what the new model will look like.
The grille here is well covered, but the photo from the front reveals the similarities to the design sketch. The rear shows a similar horizontally oriented design as the Mazda2, which the CUV is based on. However, the dipping sides around the B-pillar from the teaser don't appear to be on this tester. Even with all the swirls, the vehicle looks fairly attractive.
Mazda is doing a fantastic job of keeping mechanical details about the CX-3 a secret. It's not yet known whether the model is front-wheel-drive only or if all-wheel drive is also an option. The crossover also likely shares the Mazda2's engine, which isn't revealed for North America, yet. The diminutive CUV will compete with a huge crop of new classmates, including the Fiat 500X, Jeep Renegade, Chevrolet Trax and Honda HR-V. Check out the gallery for the latest glimpses of this Japanese CUV just days ahead of its full debut.

2019 Mazda CX-5 turbo model seemingly confirmed, doesn't come cheap

We reported last month on some leaked documents that announced the 2019 Mazda CX-5 would get the turbocharged 2.5-liter four-cylinder as an option, and it's looking even more official now that additional documents have appeared on Reddit. The new information comes from a "Product Information Bulletin" that not only confirms the engine's availability but reveals pricing, trims and feature sets for the new model year. As it turns out, the turbo CX-5 won't be cheap. The base price for a CX-5 with that engine will be $35,865 with destination. That's about $5,500 more than the cheapest turbocharged Mazda6. There are a couple of reasons for this. The turbo engine will only be available on two new high-end trims for the CX-5, Grand Touring Reserve and Signature. Both of those trims bring a variety of high-end features and options with them. It can also only be paired with all-wheel drive. The Mazda6 turbo engine is available on the slightly lower Grand Touring trim and is only paired to a front-drive drivetrain. Conspicuously absent from the 2019 documentation though is the elusive Skyactiv-D diesel engine. This is strange, since the engine has been rated by the EPA, so it's presumably ready for introduction to the U.S. market. We'll be curious to learn that engine's fate. We could see the turbo gas engine threatening the diesel's U.S. introduction, since it delivers the same amount of torque as the diesel with more horsepower. Plus the diesel didn't get amazing EPA numbers. But that's just speculation on our part, and it's entirely possible the diesel will still come here. The rest of the CX-5 lineup sees some welcome upgrades, too. The infotainment on CX-5s starting with the second-lowest Touring model will get standard Apple CarPlay and Android Auto compatibility. All models also will receive G-Vectoring Plus. The feature, along with the turbo engine option, was announced for the Japanese CX-5 recently. What this system adds is a little bit of braking force to the outside wheel as the driver winds the wheel back to a straight position when exiting a corner or completing a lane-change. The idea is that it helps make the car more stable when straightening out after a turn. Also, although the turbo CX-5 models will be rather pricey, the other CX-5 models won't change much in price. The base Sport trim starts at $200 more than the 2018, the Touring model increases just $100, and the Grand Touring goes up by $400.

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.
