Mazda says Skyactiv-X will come to the U.S, but not when

Mazda executives say the new 2.0-liter Skyactiv-X powerplant will still take some time to arrive to the North American market. The Skyactiv-X is a high-compression gasoline engine, and its 16:1 compression ratio is comparable to that of a diesel engine. "We have a lot of technology. And we are introducing each technology in each region when the time is right," said Mazda North America CEO Masahiro Moro at the SAE International WCX Conference, according to Automotive News. Moro stated that while the Skyactiv-X can indeed pass EPA emissions regulations, it's not in the immediate pipeline for U.S-bound Mazdas; the slightly less hardcore Skyactiv-G will be amended first. The launch-spec 2.5-liter Skyactiv-G engine in the new Mazda 3 will reportedly be supplemented by a 2.0-liter Skyactiv-G, which also has a bold compression ratio: according to Mazda, its ratio of 14:1 is the highest of any production gasoline engine. However, Moro didn't state the exact timeline for that Skyactiv-G's arrival, either. The compression ratio of the 2.5-liter "big block" available now is 13:1. In the 2019 model-year Miata roadster, the 2.0-liter Skyactiv-G makes 181 horsepower, and an earlier Slovakian Euro-spec leak mentioned the 2.0-liter 3's power figure at 164hp. The bottom line is thermal efficiency through being able to extract more energy out of gasoline, and moving from G to X would improve fuel economy by 20-30 percent while giving more power. If the Slovakian specifications are to be believed, the Skyactiv-X would make 178h p and 164 lb-ft in the Mazda3.

Race-inspired Mazda 3, CX-5, and Miata look great with white letter tires

At the 2020 Tokyo Auto Salon, a customization show that is kind of like SEMA but definitely not the same, manufacturers promote what is available and explore what's possible. Mazda brought a variety of vehicles to the show, but none more intriguing than the Mazda Motorsports Miata, Mazda3, and CX-5 concepts. The trio has race-inspired graphics, as well as a slew of visual and mechanical changes. The three vehicles have a core pack of changes, then each one has its own signature pieces to create some differentiation. The roadster, hatchback, and crossover have height-adjustable suspensions, upgraded brakes, MazdaSpeed tow hooks, circular number body decals, new wheel nuts, Alcantara steering wheels and shift knobs, special heel plates, MazdaSpeed six-point harnesses, and MazdaSpeed sport seats. The Miata and 3 have Fujitsubo stainless mufflers, while the CX-5 has a slightly different exhaust. The Roadster appropriately has the most involved individual upgrades. It has a body kit with front, side, and rear alterations, and it sits on RAYS ZE40 17x7.5J wheels wrapped in Potenza RE-71R 215 / 45R17 rubber with beautiful white lettering. It also has a Cusco roll bar, a MazdaSpeed rear spoiler, a MazdaSpeed strut bar, and a MazdaSpeed lower arm bar. Inside, the door trim, decoration panel, shift boot, center console lid, and parking brake boot are draped in Alcantara. An aluminum pedal set is adds a final touch of polish. On the Mazda 3 hatchback, the aero kit is specifically noted to be "Signature Style." Mazda also upgraded the strut bar and lower arm bar, and threw on Rays ZE40 18x7.5J wheels in Potenza RE-71R 215 / 45R18 tires, also with white lettering. Black mirror caps, a scuff plate, and a sports pedal set complete the concept. On the CX-5, Mazda made it sportier but also added some crossover-focused features, too.. It has Mazda-styled aero, an Auto Exe sports muffler Rays G25EDGE F1 20x8.5J wheels, Bridgestone ALENZA001 255 / 45R20 tires with white lettering, and a new wheel nut set. It also has a scuff plate, premium floor mats, a premium luggage mat, and sports pedals. For now, these are only concepts, with no word as to whether anything similar could hit Japanese markets, let alone U.S. shores. A Mazda engineer previously said a MazdaSpeed3 wouldn't happen, but the company is reportedly considering a 3 with a 250-horsepower 2.5-liter four-cylinder engine.  Related Video: This content is hosted by a third party.

2014 Mazda Skyactiv Prototype looks ready for Daytona

With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.
The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.
Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.
