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.

Japanese automakers ramping production for renewed American sales

The 2011 earthquake and tsunami that struck Japan took quite the toll on the automotive industry in that nation. Not content to lean on that tragedy as excuse for slagging sales, the Japanese automakers are planning on a major production expansion in North America. The aim is to reclaim the market share lost from the Tsunami-based dip, and overcome a dollar/yen exchange rate that makes exporting to America unprofitable.
Following the Tsunami, Japanese automakers ramped up production in their North American facilities to compensate, but according to Automotive News, Nissan, Honda and others have all reported plans for still-further increased production in the year ahead. As part of this ramp-up, Mazda will open a facility in Salamnca, Mexico before March of 2014. Part of that increase in output is 50,000 units of a Toyota-badged compact car, which Mazda will produce.
Other Mexican production facilities opening include a Honda plant, which will open in Spring 2014 in Celaya, and a Nissan plant, set to open later this year in Aguascalientes. Nissan also said that it will need another plant in North America within the next five years. According to Nissan Boss Carlos Ghosn, the company aims to raise its stake in the US market from 8 percent to 10, and adding production will help achieve that goal. Even Mitsubishi is aiming to boost production at its Normal, Illinois plant. Production of the Outlander Sport is currently at 50,000, which Mitsubishi wants to raise to 70,000.

Ford, Toyota clean up in Best Car For The Money Awards

The U.S. News Best Cars for the Money Awards picks winners by looking at the average transaction price, five-year total cost of ownership, the regard a car has from the automotive press, reliability figures from J.D. Power and Associates and safety data from the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety. The result, according to the magazine, is "the best combination of critical acclaim and long-term value."
Ford nabbed six of the 21 categories that received awards this year, the Focus, Fusion, Fusion Hybrid, Taurus, Escape and Edge getting trophies. Toyota and its Lexus and Scion sub-brands took another five, the Tacoma and Tundra owning the two categories given to pickup trucks. The other ten awards were split between Honda with three, Buick with two, and one each for Subaru, BMW, Hyundai, Chevrolet and Mazda.
