2019 Mazda Miata officially announced with 181 horsepower

It turns out the rumors and leaks are true. The 2019 Mazda MX-5 Miata will indeed get a slight performance increase. This fall, the car's naturally aspirated 2.0-liter inline-four will make 181 horsepower and 151 pound-feet of torque. That's a 26 horsepower and 3 pound-feet bump over the 2018 model. It may not sound like a lot on paper, but consider the fact that it's a nearly 17 percent increase in power in a car that weighs just 2,332 lbs. When the current ND generation debuted a few years back, the Miata actually took a slight hit to power. It was offset by a sizable weight loss program, but it didn't stop people from making a fuss. These days, it's not often that a newer model actually loses power compared to the outgoing car. The new car now makes roughly the same power as the old turbocharged Mazdaspeed MX-5 from 2004. Peak power for the 2019 model comes at 7,000 rpm while peak torque arrives at 4,000 rpm. That's 1,000 more and 600 fewer revs respectively. The Miata's redline is now 7,500 rpm, up from 6,800. It should make the car feel more lively through the rev range and should drop the car's 0-60 mph time back under 7 seconds. The 2019 model only weighs 7-pounds more than the outgoing model, so it's essentially a non-issue. In order to get the extra juice, Mazda engineers did some significant work to the engine's internals. Piston mass has been reduced 27 grams while the connecting rods are down 41 grams. The exhaust system and inner exhaust manifold have been modified to reduce pumping losses by 30 percent. The intake and fuel injectors have been changed, too. A new dual-mass flywheel replaces the single-mass unit. This should help better manage engine vibrations and responsiveness. Lastly, the final drive ratio has been increased from 3.454 to 3.583. Other gear ratios remain unchanged. There are other minor but welcome changes for 2019. The steering wheel now telescopes, a boon for drivers with long legs. The doors are easier to open and feature revised door stops. The cupholders and seat levers have both been updated. Finally, there are new 17-inch wheels and a new brown canvas soft top. How all these changes will affect the car remain to be seen. While many people have been clamoring for more power, some of us here at Autoblog feel the Miata may lose some of its current character with such a significant shift in power and torque. Either way, we're as excited as ever to get behind the wheel. 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.

Mazda Koeru concept forecasts next CX-9 in sleek form

Mazda rolled in to the Frankfurt Motor Show this year with the Koeru concept you see here. The showpiece is the latest embodiment of the Japanese brand's Kodo design language, applied with dramatic effect to a large crossover shape. Could this preview the next CX-9? The Koeru takes its name from the Japanese verb for "going beyond," and the reason is plain to see: though created by a mass-market brand, the concept could easily belong to an upscale marque like Infiniti (which offers a range of crossovers), Jaguar (which just revealed its first), or Maserati (which is preparing to get in on the action as well). It strikes us as aggressive as it is elegant, with taut lines and sporty details from the sharp lights to the muscular wheel arches. Few technical details as to what lies underneath it all were made available. And these show cars often lack working underpinnings to speak of anyway. But Mazda says that, beyond the styling, it optimized the aerodynamics over the upper body as well as underneath it to reduce turbulence and "enhance vehicle stability when driving at speed." It's also said to encompass the company's latest Skyactiv, i-Activesense, and Mazda Connect technologies. Which is all well and fine, but we're looking forward to seeing what innovations the company might incorporate if and when the Koeru (hopefully) transitions from concept to reality. In the meantime you can scope it out in the live and stock image galleries above and below. MAZDA KOERU The all-new crossover concept proposed by Mazda Mazda Motor Corporation is unveiling the all-new crossover concept Mazda KOERU for the world premiere at the Frankfurt Motor Show this year. The Mazda KOERU demonstrates Mazda's unique and daring interpretation of a crossover vehicle, proposed for the fast-growing crossover market. Featuring the full suite of Mazda's new-generation SKYACTIV technologies and designed under the KODO—Soul of Motion design language, the concept offers sporty yet delightfully refined styling and driving performance. The name "KOERU", which literally means "exceed" or "go beyond" in Japanese, comes from Mazda's aspiration to deliver value that goes well beyond the existing category norms and standards. As the latest incarnation of Mazda's new-generation products, the Mazda KOERU crossover concept offers styling that exudes power, vitality and a new level of polished refinement.
