2019 Mazda CX-5 Signature AWD diesel unveiled in New York

NEW YORK —It seems like we've been waiting forever, but the wait is finally over. Mazda has finally launched a diesel version of the CX-5 for the U.S. market, unveiled at the 2019 New York International Auto Show. Specifically, the 2.2-liter Skyactiv-D turbo-diesel engine will be offered in the higher-end CX-5 Signature AWD, part of what Mazda calls its "path to premium," as the company continues to set its sights on some of the more expensive competition. The Skyactiv-D 2.2 makes use of a sequential twin turbocharger that employs a smaller turbocharger first at low rpm for quick throttle response, after which a valve opens to spool up a larger turbocharger at higher rpm. Mazda says this provides "smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque." Mazda estimates the output of the engine to be 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm. The engine has a rev limit of 5,500 rpm. As of right now, it's only in the all-wheel-drive version and only in the Signature trim level. As such, it gets a ho-hum EPA fuel economy rating of 27 mpg city, 30 highway and 28 combined. We previously saw fuel economy figures for a potential front-drive diesel CX-5 getting just slightly better fuel economy, at 28 city, 31 highway and 29 combined, but no word yet on if and when that'll be made available. The mediocre diesel fuel economy, while expected given the midstream shift from one emissions strategy to another, is particularly disappointing in context. The non-turbo CX-5 AWD, which makes 187 hp and 186 lb-ft, gets 24 city and 30 highway for 26 combined mpg – just 3 mpg less in the city and 2 mpg less overall than the diesel. The much more powerful CX-5 Turbo, which makes 250 hp and 310 lb-ft, gets 22 city, 27 highway, and 24 combined. Mazda is taking pre-orders for the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 starting now, at an MSRP of $42,045, including $1,045 in destination fees. We have to point out that this is a sizable jump in MSRP from a CX-5 Signature AWD with the more powerful turbo engine, which lists for $38,235 – a $3,810 difference in fact. Given the lackluster fuel economy and considerable decrease in power and torque, we're concerned that the diesel may be a tough sell at this sort of premium.

Are you the 2016 Mazda Miata?

Tech nerds are spoiled. Every year, there's a new iPhone that arrives following months and months of breathless speculation and rumormongering. We car folk have a more difficult life, because vehicles with the iPhone's cult-like devotion and following, while plentiful, only receive hefty updates after several years. Case in point, the Mazda MX-5.
There's a new one coming, and much like the iPhone 6, it'll arrive in just a few weeks. So, in lockstep with the tech folk, we're anxiously biding our time and waiting with baited breath for the expected debut date of September 3. Also, like Apple fanboys, we're clamoring over any hint or teaser as to what the next-gen Miata will bring, which is why we're showing you the above image.
That is, allegedly, the new MX-5 hiding under the sheet. Auto Motor und Sport has the image, which according to World Car Fans was released by Mazda. Of course, we've reached out to the Zoom-Zoom brand for verification of its authenticity, and will be sure to update as soon as we hear back.

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.
