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.

Road & Track to take Miata on million-mile march

Road & Track has taken on a Miata project. One hell of a project, if we're honest. You see, the Miata in question, a 1989 example in Mariner Blue, isn't a high-mileage Mazda that the publication intends to fix up, or make race-worthy, or try to flip or give away to a reader or something. No, it's a rather typical well-used NA, with a hefty 325,000 miles on the clock to-date that the staff plans on driving until the six-digit odo reads all zeros again. One million miles or bust (or both, most likely).
Procured for the bargain-basement price of $1,600, complete with seat covers that "really do look like muppet pelts" (according to Zach Bowman) and a bondo-filled love tap on the nose, the NA Miata actually looks like just the sort of fun-machine that a real driving enthusiast would pick up to get some cheap thrills in. The R&T team already has some interesting plans for the Miata, including a potential run up Pikes Peak and loaning it out to readers (or perhaps your author...). Click through to read all about it.

2020 Mazda MX-5 Miata due for price bump, more safety tech

Mazda hasn’t released official information yet on its 2020 MX-5 Miata, but CarsDirect got its hands on an early draft of an order guide, which suggests both the soft- and hard-top versions of the roadster are due for a price bump after receiving more standard safety technology and some suspension upgrades on certain manual models. Starting price on the 2020 Miata Sport Soft-Top will be $26,580, not including destination, which is reportedly not yet listed, according to the report. ThatÂ’s $850 above the non-inclusive 2019 base price. The price hike on the Grand Touring trim is even higher, at $1,090. For the RF Club Hardtop, starting price inches up by $700 to $33,045 — again, excluding destination, which was $895 for 2019. If you want to drive stick, prepare to pay more for the Grand Touring manual versions, which will climb by $890 and $1,090 for the soft- and hard-top versions, respectively. ThatÂ’s down to new Bilstein shocks, a limited-slip differential, front shock tower braces and a sport-tuned suspension, which should make for fun driving for stick enthusiasts. The big news is that the i-Activesense suite of safety technologies, previously offered as a package, will go standard across all trim levels. It features lane departure warning, blind-spot monitoring, rear cross-traffic alert and low-speed automated braking. Apple CarPlay and Android Auto will also reportedly debut on both versions of the roadster as standard on Club trims and above. The Miata is already coming off a 2019 when it got an infusion of 26 more ponies and 3 pound-feet, bringing output to 181 hp and 151 lb-ft from its 2.0-liter Skyactiv-G inline-four engine, plus that limited-edition 30th Anniversary model. Looking ahead, Mazda is reportedly toying with the idea of electrifying its lightweight roadster for its next generation, expected mid-next decade. Related Video:
