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.

Mazda's product roadmap after Skyactiv-X: diesel, rotary, hybrids, even EVs

When we first heard that Mazda had cleared the major hurdles on gasoline compression ignition, and were just tidying up the details with clear production intent, the first kneejerk thought was: That's it for Mazda's consumer diesel. In particular, the Skyactiv-D that was intended for sale in the U.S., only to be delayed for years by various regulatory roadblocks and other issues that Mazda is frustratingly (but understandably) vague on. At least, it'd die out at some point down the road once Skyactiv-X was widely available. It turns out that's not the case at all. Mazda will adopt an approach that becomes more and more electrified and diverse the closer you get to 2035. But internal combustion will play a deep and central role up to that point, and probably beyond. Before we get to what those different powertrains, diesel and electrified, will look like down the road, let's stop and think about Mazda's philosophy. It couldn't be more different from the approach of most manufacturers that are currently producing BEVs and hybrids, which are heavily incentivized by both the automakers and the government, both state and local, depending on the locality. Even with all that cash on top of the hood, the market penetration of electrified vehicles is low. Mazda's too small to lose money paying people to drive EVs and hybrids. Its risky solution (which is plucky, but has had mixed results) is to simply improve the internal combustion engine. It's achieved the best fleet average fuel economy in the U.S. already, using a range of direct-injection gas engines that are mostly naturally aspirated. A few tiny nods to electrification have been introduced, like i-eLoop regenerative braking and the Demio EV (a Japanese-market, last-generation Mazda2 with a 20kWh battery that was tested with a tiny rotary engine range extender). But the focus is on combustion, not electricity. And that focus isn't going away anytime soon. Mazda believes that pure gasoline, gasoline hybrid, and gasoline PHEV vehicles will remain the vast majority of vehicle sold through 2035. At that point, Mazda forecasts, BEV and fuel cell vehicles should make up about 15 percent of the total of Mazda's lineup. The remaining 85 percent will utilize some form of internal combustion engine. Now, that includes hybrids and even a small number of CNG/LPG cars. And these are global numbers, as well. There may be even fewer fuel cell and CNG/LPG vehicles sold here than abroad.

Mazda's Hofu plant builds its ten-millionth car

Ten million is a lot no matter which way you cut it, and no matter what you're talking about: Ten million dollars, ten million miles, ten million people... certainly ten million cars. And that's the milestone that Mazda's Hofu plant in Yamaguchi prefecture of Japan has just achieved.
The Hofu facility has been in operation since 1982, and was supplemented with a second plant on the same site ten years later. Hofu reached a million units built in 1986 and five million in 2002. But with production now at 482,100 units per year, it took less than twelve years to double that previous milestone.
The magic ten-millionth car was a new Mazda6 (known locally as the Atenza), which is built at Hofu Plant No. 2, while Hofu Plant No. 1 gears up for the new Mazda3 (aka Axela). Scroll down below for a related press release.
