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.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mazda5 may not be long for this world

The concept behind building a smaller but still useful minivan like the Mazda5 always seemed like such a good idea. However, since the little people hauler's introduction, there has been the rise of the compact crossover in the US, which fulfills a similar niche for many buyers. The future is not looking good for the utilitarian Mazda. Autocar from the UK reports that company officials confirm the Mazda5 is being discontinued there, with no replacement planned. Autoblog reached out to Mazda North America, but the company would not verify future product changes in this region. Though, the model's cancellation would hardly be a surprise to follow in North America, as well. The minivan market is a tough place these days, and dealers tend to prefer more expensive models for their high margins. Even FCA US is abandoning the inexpensive portion of the segment for the next-gen Chrysler Town & Country. The Mazda5 isn't exactly a sales standout, either. Mazda sold 11,613 of them in all of 2014, which was a 16.4 percent drop from 13,884 in 2013. To compare to larger, more expensive minivans, Honda moved 122,738 units of the Odyssey last year, and Toyota did 124,502 examples of the Sienna.
