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 specs new MX-5 Miata with accessories

It's been 26 years since Mazda showcased the original Miata at the Chicago Auto Show, and now it's returned with a conceptual take on the new model, decked out with all the accessories and optional equipment your roadster-loving heart could desire. Or at least some of 'em, anyway. This show car is painted Ceramic Metallic (Zoom Zoom-speak for "white") and spec'd out with a full aero kit (including front air dam, side sills, rear skirt and lip spoiler) all done up in gloss black, 17-inch BBS wheels and Brembo brakes with red calipers. Mazda is also showcasing a carbon-fiber luggage rack for the new MX-5 that weighs less than two pounds and includes and integrated brake light. "The concept parts and accessories we have showcased at the Chicago Auto Show," said Mazda's North American chief Jim O'Sullivan, "were developed to give customers a look at what is possible for the new cars to make them truly one-of-a-kind, adding to that excitement."

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:
