Mazda3 with Skyactiv-X engine technology caught testing in the wild

Sometimes, automakers are fine with their mules coming under the watchful lenses of spy shooters. Proof of this can be seen plastered across the bodysides of the Mazda3 mule you see above. Clearly, Mazda wants the world to know that engineers are working hard on the company's so-called Skyactiv-X engine technology so badly that it's created a custom matte black vinyl wrap for its test mules. Clever. Expect to see this sweet new engine tech in the 2019 Mazda3. This SCCI, or Spark Controlled Compression Ignition system holds tremendous potential to boost the efficiency of gasoline-powered engines by 20-30 percent, thereby matching the fuel economy of a comparatively sized diesel engine. As an added bonus, torque figures are expected to jump a similar amount. Besides the placard-sized stickers, there isn't much to see here. The car is clearly a Mazda3 hatchback, though the fenders are punched out a bit and the fuel door is modified from stock. We'd wager that future prototypes will wear a lot more camouflage to cover up next-gen bodywork. In other words, stay tuned.

Driving classic Mazdas to experience the weird and wonderful rotary's triumph

AUGSBURG, Germany — Everything weird and wonderful about Mazda's relationship with the Wankel rotary engine is embodied in the delightful 110S Cosmo Sport of 1967. Just shy of 1,200 were built and, for most of its life, it remained a Japanese curio. Driving one is a rare privilege, and yet here I am, leading a convoy of owners through Bavaria away from a private museum holding the most extensive collection of Mazdas outside of Japan. Created by local franchise holder Walter Frey, what started out as a business relationship in the 1970s has blossomed into a lifetime love affair. Whether the residents of Augsburg are quite so enamoured is another question. As I leave the museum I pass a sign proclaiming my entry into an "umwelt zone" for low-emissions vehicles. The oil-tinged plume of smoke in my wake rather makes a mockery and underlines one reason there are no rotary engines in the current Mazda product range. Created by a German but perfected by the Japanese, it seems appropriate to celebrate the association with the Wankel engine here. Mazda may have gone on to sell nearly 2 million rotary-engined cars to the world — the U.S. included — but 50 years ago it brought two Cosmos to the Nurburgring and entered them into the grueling Marathon de la Route as a proof of concept. After 84 hours of continuous running and a fourth-place overall finish, Mazda had demonstrated to the world a rotary could stay the distance. I have a slightly less grueling schedule but look forward to following the instructions to rev the hell out of the Cosmo to clear the smoke out of its system. Those following me will certainly be hoping this does the trick. A thirst for oil as well as gasoline isn't the only rotary trait. The two chambers of its motor displace 491 cc apiece, equivalent to about 2.0 liters in a regular reciprocating design. In this second-series car, it delivers around 128 horsepower, which drives the rear wheels through the transmission's five gears. There doesn't seem to be a whole lot of progress in any of them, truth be told, the characteristic lack of torque making for more noise than meaningful acceleration. It's a small car and weighs just more than 2,000 pounds, with a power-to-weight ratio not far off that of an original NA Miata. But it's one for carrying speed, not building it. The wood-rimmed Nardi wheel is one piece of luxury in an otherwise functional, vinyl-trimmed cabin, and through it the Cosmo has a nice blend of stability and agility.

Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.
