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.

1993 Mazda RX-7 Retro Review | A '90s hero turns 25

Boom times build interesting cars. In the late 1980s, Japan was flush with capital, and automakers spent like the party was never going to end. Suddenly building the third-generation RX-7 — the world's most advanced twin-turbo rotary sports car — seemed like the most natural thing a small car company hailing from Hiroshima could do. On this side of the Pacific, however, there was no context for the sudden influx of unusually tricked-out Japanese hardware flooding American dealerships. And none of the Japanese sports cars of the era was more unusual than the FD-generation Mazda RX-7, imported from 1993 to 1995 (and continuing on in Japan until 2002). Although the island nation's economy was headed on a downward spiral by the end of 1990, Mazda was in no position to pull back and walk away from the development dollars that had already been spent on its latest RX-7. As a result, Americans were able to briefly bask in the glow of one of the most unique engineering experiments ever unleashed on unsuspecting buyers. For its time, the Mazda RX-7 was a spaceship. With fluid lines that screamed "exotic," it joined the NSX in showing that supercars didn't have to have European blue blood running in their cooling systems to elegantly snag eyeballs. The twin-rotor, 1.3-liter 13B-REW situated behind the RX-7's front axle revved all the way to 8,000 rpm on its quest to produce 255 horsepower and 217 pound-feet of torque, with a pair of sequential turbos handing boost duties back and forth around the 4,500 rpm mark. A five-speed manual gearbox was standard with the FD (a four-speed automatic was optional), as was a curb weight in the neighborhood of 2,800 pounds — nearly 500 lbs less than the contemporary Toyota Supra. Significant figures for the era, to be sure. While they might pale in comparison to the average sports car today, slide into the RX-7's cockpit and drive the car, rather than just crunch the numbers. You'll quickly discover what can be accomplished when the company that engineered the Miata pulls a full John Hammond and "spares no expense" developing a world-beating sports car platform. The 1993 Mazda RX-7 I've been loaned from Mazda's classic collection is an R1 car, which means tighter suspension tuning, a few cosmetic upgrades, and a Competition Yellow paint job.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
