Mazda's Tokyo concept foretells of rotary revival

Mazda has long been rumored to be planning a revival of its rotary-powered sports car. Some of those rumors may have come down to wishful thinking as much as concrete information. But now, on the eve of the Tokyo Motor Show, new details have come to light. The Japanese automaker is slated to unveil a two-door sports car concept, previewed in the teaser image above. Little in the way of firm information has been made available prior to the show car's debut, but sources are now citing senior company officials as confirming it has a rotary engine. "It is a two-door, two-seater, Mazda CEO Masamichi Kogai told Autocar. "It is a pure sports car design. We have MX-5 and another icon is a rotary sports car. We haven't talked about market reach but this would be in that segment." R&D chief Kiyoshi Fujiwara added: "People think rotary can not meet modern eco demands. The SkyActiv engineers worked on rotary and gave it cutting-edge tech. It is an essential part of our DNA and it [will] just be passed onto future engineers. It is synonymous with the brand. Some time in the future it will return and be called SkyActiv-R." The last time Mazda produced a rotary-powered model, of course, was with the RX-8, which ended production in 2012. That was preceded by three generations of RX-7, the first of which will be celebrating its 40th anniversary in 2018. If it manages to get the Wankel technology up to modern standards, that could provide just the right opportunity for Mazda to launch a new model. Reached for comment, Mazda spokesman Jacob Brown told Autoblog: "While we can confirm that Mazda continues to develop rotary engines, we cannot confirm production of a rotary at this point. Rotaries are one of the signature engineering technologies that define Mazda, and we will continue exploring them to see where they may fit for production applications." Related Video:

Mazda refurbishing this NFL running back's 22-year-old daily driver

I don't actually care for the Washington Redskins (which is a good thing, considering the start to their season this year), but I love their running back, Alfred Morris. Why? Well, to start with, Morris helped deliver a dominating 10-3 season for my fantasy football team last year after a flash of prescience saw me pick him up off the waiver wire in Week 1 (hit me up on Twitter if you need fantasy sports insight, guys, I'm sort of like the Ruxin of Autoblog).
Morris is also pretty endearing because of his loyalty to his car, Bentley. Hold up - that's not to say the running back has splashed out on a Continental GT or a Flying Spur. No, Morris gave his much-loved 1991 Mazda 626 the tongue-in-cheek name "Bentley" while he was still a student at Florida Atlantic. One 1,613-rushing-yard rookie season and a $2.2-million contract later, and Morris is still using his Mazda as his daily driver. It might be easy to assume that the young player is simply being really prudent with all of his newfound wealth, but the guy really just has a thing for his five-speed-manual 626.
And Mazda, of course, loves the story of Morris' affection. In an effort to keep his 626 running strong and looking good, the company's Washington D.C.-area dealers have agreed to refurbish Bentley back to its original showroom freshness. Rather than spoil the classic (?) lines of the 626, the Mazda folks are essentially restoring the car for Morris. The cracked dash will be swapped out for a factory replacement, the engine and transmission given a thorough going-over and the whole vehicle generally made as fresh as Will Smith circa 1991. Bentley is expected to be completed and rolling through the capitol city by October 15, and in the meantime, Morris has been driving around in a new 2014 Mazda6 loaner car.

Mazda working on lithium-ion batteries to replace lead-acid starter batteries

In the quest for ever better fuel economy, car companies are looking for every single advantage possible, no matter how small. This is evident in everything from active grille shutters to the 48-volt mild-hybrid electric assist systems like that in the new Ram 1500. For Mazda, the latest target for potential efficiency gains is the lowly 12-volt starter battery. The company announced that it is partnering with two other companies, ELIIY Power and Ube Industries, to develop a lithium-ion starter battery that would be used on mainstream models in place of conventional lead-acid units. Mazda plans to have them ready for use by 2021. The advantage here would be that 12-volt lithium-ion batteries would be much smaller and lighter than the lead-acid ones they replace. And lighter cars don't need as much fuel to move around. Plus, as an added benefit, making cars lighter also often makes them faster and better handling. This is why companies such as Lotus and Porsche have offered optional lithium-ion 12-volt batteries for some lightweight sports cars. A potential downside to the use of these batteries is increased cost. Lead-acid batteries from your local parts store will run you between $100 to $150. AGM batteries could be between $200 and $300. As for lithium-ion batteries, Lotus introduced the option on the Evora 400 in 2016, and the option cost $1,690. Odds are that a company such as Mazda won't be absorbing all those costs, meaning that the cost of these future Mazdas could increase with a change from lead-acid to lithium ion. Related Video:
