Mazda could electrify the next Miata, is trying to figure out how

The next Mazda Miata is at the embryonic stage of development. The men and women in charge of the project are debating whether to electrify the roadster, or if it's better to keep it true to its roots. The Miata is not a high-volume model in any market, so it doesn't need a plug to help Mazda comply with looming emissions regulations. The company explained it's not a matter of compliance; it's about how the definition of a sports car and the expectations of motorists could change in the 2020s. "The preferences of people who enjoy driving sports cars might be changing, so we need to think about what direction society is going in. We want to look at the best powertrain to keep the vehicle lightweight, but because of the diversifying requirements and preferences, we need to explore various options," Ikuo Maeda, Mazda's global design director, in an interview with Autocar. Adding any degree of electrification to the Miata beyond a relatively basic mild-hybrid system is easier said than done. An unusually low weight and a compact footprint defined the original model introduced in 1989, and these attributes continue to characterize the fourth-generation car (pictured) sold in 2019. Electrification requires batteries, batteries add weight and require space, and Mazda doesn't want to end up with a 3,000-pound Miata, or one that's the size of a Mercedes-Benz S-Class Convertible. Keeping its chassis balanced is a delicate task, too. Overcoming this challenge is not impossible, however, and batteries are expected to become lighter and smaller during the 2020s. The next-generation Miata isn't expected out until the middle of the 2020s, so Mazda has time to figure out whether it should go hybrid, arrive as an electric car, or carry on with a rev-happy, naturally-aspirated four-cylinder engine. Maeda stressed a final decision on the matter hasn't been made yet. "I don't have the answer right now, but we need to make a vehicle that people can own without worrying that they are not being eco-friendly," he concluded.

Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

Toyota, Mazda partner to build EVs at new $1.6 billion U.S. plant

TOKYO — Toyota and Mazda plan to build a $1.6 billion U.S. assembly plant, the two said on Friday, as part of an alliance that will also see the Japanese automakers jointly develop electric vehicle technologies. The two will take small stakes in each other as part of the tie-up: Toyota, the world's second-largest automaker by vehicle sales last year, will take a 5 percent share of Mazda, extending its dominance in Japan's auto sector. Mazda will take a 0.25 percent share of its larger rival. The plant, something of a surprise at a time of overcapacity in the U.S. market, will be a boost to U.S. President Donald Trump, who campaigned on promises to increase manufacturing and expand employment for American autoworkers. The plant will be capable of producing 300,000 vehicles a year, with production divided between the two automakers, and employ about 4,000 people. It will start operating in 2021. The electric vehicles cooperation, meanwhile, comes as the tightening of global emissions regulations prompts more automakers to develop battery powered cars, as the industry struggles with hefty research costs and intense competition from technology companies over technology like self-driving cars. As part of the agreement, Toyota and Mazda will also work together to develop in-car information technologies and automated driving functions. Toyota, Japan's biggest auto company, has been forging alliances with smaller Japanese rivals for several years, effectively engineering a loose consolidation of the Japanese auto sector. It already owns a 16.5 percent stake in Subaru, Japan's No. 6 automaker, with which it also has a development partnership. Toyota is also courting compact car maker Suzuki to cooperate on R&D and parts supply as Toyota seeks to tap its smaller rival's expertise in emerging Asian markets. A stake in Mazda may also prevent future incursions by tech companies, one analyst said. "For a technology company which lacks the expertise in making cars, Mazda could look like a very interesting acquisition. They're very good, they're not too expensive. Maybe Toyota realizes this," CLSA managing director Chris Richter said. "By buying a 5 percent stake, Toyota takes Mazda off the table rather than having it sit out there like a free agent which could someday be used against them." COROLLA PRODUCTION SHIFT Mazda stands to gain from a deal that gives the small automaker a production foothold in the United States.
