Mazda's rotary-engine range extender could serve as an emergency generator

GENEVA — Mazda has some pretty exciting powertrain technology in the works, particularly its Skyactiv-X spark-controlled compression-ignition engine, but also the upcoming range-extended electric vehicle with a rotary engine. It offers the possibility of electric transportation with a distinctly Mazda way of getting electricity from gas when charging isn't an option. But we learned that Mazda has some other ideas for the rotary range-extender beyond transportation, and even beyond gasoline. In talking with Ichiro Hirose, Maza's managing executive officer for powertrain and vehicle development, product planning and cost innovation, we learned that the company is exploring the powertrain's potential as an emergency generator. Naturally if an engine is suitable for creating electricity in a car, it would be suitable to provide electricity to buildings or tools. Besides a rotary engine used as a standalone generator, Hirose said the company is investigating the potential for complete cars to be used as emergency generators, since they're already mobile. Gasoline wouldn't have to be the only potential fuel, either. Hirose said Mazda is looking at possibly running the engine on liquified petroleum gas, or LPG. We asked if hydrogen was also being considered, since Mazda has a history of hydrogen-powered rotary prototypes, even some that could run on hydrogen or gasoline, but Hirose said that's not being looked at right now.

Mazda Miata getting i-ELOOP regenerative 'braking' in more markets

The Mazda MX-5 Miata is getting the company's i-ELOOP regenerative "braking" system in more overseas markets. A few months ago, the company announced it for the Japanese market, and this week it announced the U.K. will have the feature, too. This has us curious as to whether it will be offered on U.S. market Miatas. We've reached out to Mazda, and we'll update this story if and when we hear back. As a quick refresher, i-ELOOP is a system that was introduced here on the Mazda6 several years ago, and it adds a capacitor to store electricity generated by the alternator during deceleration (hence our earlier use of quotes around "braking") that can be used to run interior accessories such as the sound system and climate control. Then, with power coming from the capacitor, the alternator can be disengaged, improving the efficiency of the engine by reducing drag. And by using a capacitor rather than a battery, the system is more compact, lighter and able to recharge faster than a similarly capacious conventional battery. As for effectiveness, the Mazda6 with i-ELOOP managed to get about 5% more miles per gallon on the highway than one without, going from 38 mpg to 40 mpg. While not a massive improvement, it was a measurable, possibly noticeable one. Applying a similar gain to a Miata would increase fuel economy from 35 to nearly 36.75 mpg on the highway, based on the automatic-equipped car's numbers. The manual would go from 34 to nearly 35.7. The i-ELOOP system is standard on all new Miatas in the U.K., which includes the 1.5-liter and 2.0-liter engines with either the manual transmission or automatic. Strangely, only automatic-equipped cars get it in Japan. This means Mazda could offer it on both transmission options in the U.S. Probably the key consideration will be cost. The system, when it launched in the U.S., was only available on the most expensive Mazda6, and even then it was an extra-cost option. And looking at pricing for the U.K. Miata soft-top and comparing equivalent trim levels, the price has increased between GBP2,800 and GBP4,100. The new model does get some new standard safety features, too, but we expect the i-ELOOP system is a significant contributor. If it is offered in the U.S., it might only be available as an option, and possibly only on the more expensive trim levels to keep lower trims more affordable.

Toddler survives 60-foot fall from apartment window, lands on car

REDMOND, Wash. — A 20-month-old boy survived a six-story fall from suburban Seattle apartment window after the toddler landed on the roof of a parked car that cushioned the impact of the plunge, authorities said. The toddler "landed in a way where the car absorbed enough of the impact that he was awake and crying when paramedics arrived" Wednesday afternoon, Redmond police spokesman James Perry told the KIRO television station. The boy was in serious but stable condition at a hospital. Just before the fall, the toddler was alone in a bedroom, while his mother and two siblings were in another room, Perry said. Investigators believe the boy propped himself on the edge of a window that was cracked open, pushed through a screen and tumbled about 60 feet. The owner of the Mazda sedan that the child fell on was amazed that the boy survived. Edward Lu told KOMO-TV that the only reason the car was there was because he had decided at the last minute to ride his bike to work that day. Had the car been gone, the boy would have landed on pavement. "That's a big dent," Lu said. "I couldn't believe it."
