White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.

Subaru, Mazda profits dip; both blame exchange rates

While some larger automakers took a beating on Q4 earnings, some of Japan's smaller operations managed to keep their heads just above water despite currency issues and slumping sales industry-wide. Subaru, which capped off its 11th consecutive year of U.S. sales increases, reported a 42-percent drop in operating profit in the final quarter of 2019; Mazda, which operates on an even smaller scale, saw a 76-percent drop.  Per Automotive News, both companies faced challenges apart from navigating currency exchanges.  Subaru Subaru's 2019 was marred by warranty costs stemming from repairs on high-volume models, including the Impreza and Crosstrek. Despite the drop in profit, company revenues only slid 2.3 percent. The company also says that it has managed to curtail incentive spending, largely thanks to replacement models that needed less help moving out of showrooms.  America remained a bright spot, with 2019 sales volumes increasing by nearly 3 percent over 2018. Subaru is hoping that figure will increase to 4.0 percent in 2020. Subaru's wholesale deliveries also increased in western Europe, but dropped precipitously (28 percent) in the company's home market.  Mazda The smaller Mazda faced similar challenges, but its 2019 lacked some of Subaru's more dramatic bright spots. Worldwide shipments of new vehicles dropped by 8 percent, aiding a revenue decline of 5 percent. Mazda's vehicles remained profitable on a per-unit basis, but only just.  Mazda has been undergoing aggressive cost-cutting measures, but even those were no match for reduced volumes and unattractive currency exchange rates.  Despite these challenges, both companies are keeping their earnings outlooks unchanged. The fourth quarter of 2019 represented the third quarter in both companies' fiscal years, which will end in March.  Related Video: This content is hosted by a third party.

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.
