Mazda's EV resistance may mean CAFE trouble ahead

Is Skyactiv the limit for Mazda? The Japanese automaker has ridden its gas-powered engine technology platform to the upper end of fleetwide fuel economy among automakers in the US. But the company's lack of electrification, either hybrids of plug-in vehicles, combined with increasing sales of crossovers, may limit future fuel-efficiency gains, Automotive News reports. Mazda has no plans to add battery-electric variants across its product line, the publication says, citing comments from Mazda North America CEO Masahiro Moro. So far, the dependence on Skyactiv has worked well, as Mazda was the second automaker - after electric-vehicle maker Tesla Motors – to meet the US fuel-economy mandate of 34.1 miles per gallon for 2016. Additionally, Mazda plans to unveil the second-generation version of Skyactiv next year. Using a technology called "homogenous-charge compression ignition" (HCCI), Mazda's gas-powered engines will approximate the compression in diesel engines, boosting fuel economy accordingly. Because of that development, Mazda's Moro is "very confident" that the company will meet the US Corporate Average Fuel Economy (CAFE) mandate for 2021. With no plans for US plug-ins or hybrids (Mazda's only hybrid, a variant of the Mazda3, is sold in Japan), Moro is not so sure about meeting the 2025 CAFE mandate of 54.5 mpg (which equates to a "real world" fuel economy of about 40 mpg). Additionally, Mazda's "biggest regulatory headache" will be meeting California's mandate that 15 percent of the state's new-vehicle sales be zero-emissions within the next decade. In 2011, Mazda laid out its strategy of leaning on its Skyactiv technology instead of moving to drivetrain electrification as a way to boost fleetwide fuel economy, saying at the time that "you can't out-Toyota Toyota and you can't out-Honda Honda." The company also took a strong stance against even the idea of electrification in vehicles. According to the US Environmental Protection Agency (EPA), Mazda's model-year 2015 vehicles averaged 30.1 mpg, beating out Honda's 28.9 mpg, Subaru's 28.7 mpg, and Nissan's 28.3 mpg. Mazda's fleetwide fuel efficiency increased from 29.4 mpg for the 2014 model year, and from 28.1 for the 2013 model year, according to the EPA.

Mazda rotary engine returning, in an autonomous Toyota delivery vehicle

With the return of the Toyota Supra, the Lotus Esprit and Mazda RX-7 probably share the trophy for hardcore sports cars we'd most like sequels for. The Esprit's too hopeless to consider. Mazda continues to speak in riddles about a new RX-7, but the company has confirmed that the RX-7's heart will return: The company's building a rotary-engined range-extender engine for an autonomous Toyota. At this year's Consumer Electronics Show, Toyota announced its e-Palette autonomous electric delivery vehicle. The e-Palette will come in bus, shuttle, and car versions to service the delivery needs of companies like Amazon, Pizza Hut, and Uber. They'll also be built in custom configurations such as mobile hotel rooms and emergency command centers. Toyota owns 5.25 percent of Mazda, the two automakers recently signed a deal to open a factory in Alabama, and Mazda's known for ace work with small engines. It's not surprising that Toyota chose Mazda for help with the e-Palette, but the rotary aspect is novel. Mazda U.S. president Masahiro Moro said, "This is a very suitable engine to run a generator because it's compact and lightweight, with no noise or vibration, and it has very good fuel economy." There have been rumors of this development previously, as far back as 2016, then again last October in reference to an electric architecture Mazda intended for release in 2019, but Toyota was never mentioned. As to pining for that RX-7 redux, Mazda's head of powertrain said the company's overcome the technical issues of a sports-car-sized rotary engine — the challenge is making a business case for such a sports car. We think the RX-VISION made the case three years ago, and it's already fitted with the Skyactiv-R rotary. Separately, a Toyota spokesman added that the two companies are looking into whether the rotary can be useful beyond the electric car. That's not much to go on when it comes to pining for another RX-7, but hope lives on a scanty diet. Related Video:

MotorWeek checks out two sides of the '90s Japanese car scene

MotorWeek's Retro Reviews let you feel nostalgic about a huge range of classic cars, and the latest two releases offer a look at two very different sides of the Japanese car market in the 1990s. The video above shows off tuned examples of the Mazda RX-7 and Nissan 300ZX. Check out the clip below to remember the 1997 Honda CR-V, if you want to reminisce about something a little more utilitarian. The RX-7 and 300ZX were among the era's best Japanese sports cars, and these examples' suspension and engine overhauls gave them an extra boost. Peter Farrel Supercars tunes the Mazda, and the vibrant yellow paint and body kit make it look ready for an episode of Initial D. The updated powertrain stands up to the mean styling and gets the RX-7 to 60 miles per hour in 4.5 seconds. The Stillen 300ZX GTZ sports a giant wing, and new turbos take the output to 465 hp. It sprints to 60 in 4.9 seconds. The CR-V sits on the opposite end of the automotive spectrum as the tuned RX-7 and 300ZX, but it's even more important in a historical sense. The Honda (along with the Toyota RAV4 and others) was among the progenitors of today's mega-popular compact crossovers. These early examples set the foundation for offering buyers a utilitarian vehicle in a comfortable package with good fuel economy at an affordable price. The CR-V had some quirky charm, too, like the removable picnic table hidden in the cargo floor. This content is hosted by a third party. To view it, please update your privacy preferences.
