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 hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Recharge Wrap-up: BlaBlaCar raises $100M, NASA launches CO2 satellite

BlaBlaCar, a ridesharing startup in Europe, has raised $100 million in a funding round led by Index Ventures. After recently growing to 12 countries and 8 million users, BlaBlaCar plans to us the funding for even more aggressive growth throughout Europe. The ridesharing service pairs drivers and passengers, allowing passengers to catch rides between cities while allowing drivers to save money on fuel on road trips. Drivers are not allowed to make a profit, and are only allowed to charge enough to break even after BlaBlaCar takes its percentage, to keep costs low for everyone involved. BlaBlaCar doesn't currently have plans to break into the US. Read more at The New York Times or at Gigaom. NASA has launched its Orbiting Carbon Observatory-2 into space to keep track of carbon dioxide in Earth's atmosphere. After being delayed on Tuesday, the Delta II rocket equipped with an instrument to measure CO2 launched from Vandenberg Air Force Base in California at 5:56 am on Wednesday. It is ultimately headed for a polar orbit to watch how CO2 levels rise and fall throughout the seasons, in part to try to figure out if the land and oceans will continue to be able to absorb half of carbon emissions. The mission will last two years, and should give further insight into climate change. Learn more in the video below, at NASA or at New York Times. Mazda is likely to release a plug-in version of its Mazda2 hatchback with a rotary range extender, reports Australian site Motoring. The electrified Mazda2, and any other future Mazda EVs and hybrids, will likely be limited to markets with government subsidies for such vehicles (which doesn't include Australia) says Mazda Australia Managing Director Martin Benders. "As the best possible fuel economy at an affordable price hybrid doesn't make sense, because the fuel economy gain isn't that great unless half of all sales are hybrid, which won't happen without big tax breaks like in the Netherlands," said Benders. That doesn't rule out the US, though. A prototype version of the range-extended Mazda2 featured a 0.33-liter rotary engine to provide power to the lithium-ion battery pack when depleted. A 2.6-gallon gas tank essentially doubled the electric Mazda2's driving range to 250 miles. Read more at Motoring. Zap plans on selling 1,000 Urbee EVs per month to SunRa for distribution in China.
