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.

Mazda's game plan: Compression ignition, superchargers, EVs — and still fun to drive

Today, Mazda announced its new Sustainable Zoom-Zoom 2030 initiative. Dumb marketingspeak name aside, this is Mazda's general plan to make its cars more efficient while still keeping Mazda's fun-to-drive character. The most notable part of this announcement is Mazda's new Skyactiv-X engines and the addition of EVs and electrified powertrains starting in 2019. As we reported back in January, this new supercharged Skyactiv-X engine family will be the first to use high-compression ignition, or HCCI, rather than traditional spark plugs. Each year, fuel economy and CO2 emissions standards grow ever tighter. Each and every automaker around is looking for ways to improve both factors. Initially, most have chosen to downsize engines and add turbochargers. That's why Mazda's new Skyactiv-X engines are going to be so special. They essentially work like a diesel engine, using extremely high compression to ignite the fuel rather than the flame from a spark plug. Adding a supercharger rather than a turbo retains a smooth and immediate engine response. Look for a 10 to 30 percent increase in torque and a sizable boost in fuel economy. Mazda's engine already have some of the highest compression ratios around, but these new engines will push well into diesel territory. The biggest issue so far with gasoline compression ignition is controlling when the gasoline ignites. Mazda claims to have solved this issue, seamlessly moving from spark to compression ignition. This new plan comes 10 years after the first Sustainable Zoom-Zoom initiative was announced. With Sustainable Zoom-Zoom 2030, Mazda wants to focus on the Earth, society, and people. Together with the new engines, Mazda hopes to create a sustainable future that still involves engaging and fun-to-drive automobiles. First, Mazda wants to consider emissions over the entire life of a car. That means reducing emissions generated while building the car or fueling and charging a car in addition to those released while it's on the road. The goal is to reduce emissions to 50 percent of 2010 levels by 2030, and a 90 percent reduction by 2050. New electrified models will debut in 2019 in markets that have a high ratio of clean energy for power generation. Mazda's focus on society aims to improve safety with the Mazda Proactive Safety philosophy. Like with Skyactiv, this ethos goes far beyond simply improving an engine or adding new active safety technology.

Alfa Romeo takes Spider in-house, Mazda-Fiat roadster partnership not dead

It's officially off. Following a report in March of this year that the marriage of Mazda and Alfa Romeo to produce a MX-5-based Spider was in trouble, the Italians have confirmed that it will take development in-house. "As far as the Spider goes, the final version is of course no longer the two-seater FCA co-developed with Mazda but a derivative of Project Giorgio," Maserati and Alfa Romeo brand boss Harald Wester told Car. For those not in the know, Project Giorgio is Alfa's codename for the rear-drive platform that will underpin the next-generation Spider, not to mention the replacement for the 159 sedan and a few other products. All is not lost for the Japanese-Italian partnership, though. "The Far East import will probably find a new home with Fiat-Abarth," Wester told Car. Yes, you read that correctly, Mazda is still working with FCA, and the result will eventually end up with Abarth's scorpion badge. If anything, we're more excited over this news than the idea of an Alfa MX-5. But we want to know what you think – would you rather Alfa build a new Spider on the Miata's bones, or does an MX-5 Abarth sound like more fun? Have your say in Comments.
