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:

Will Mazda show the next Miata's chassis in NY?

Mazda is being very sneaky about what it is bringing to the New York Auto Show, and it might have something to do with the next-generation MX-5 Miata. Australian website Motoring.com.au spoke to a company insider who told it that at least the chassis for the roadster would debut in Manhattan. The rumor goes that the show will act as the kickoff for the PR campaign for the new model.
We contacted Mazda USA PR Director Jeremy Barnes to find out more, and he would neither confirm nor deny the rumor. "Just because you read it on the Internet doesn't mean you should repeat it," he said to Autoblog. That's not exactly an outright, No.
Supporting evidence that the new drop top might be appearing in the Big Apple includes Mazda's plan to celebrate the model's 25th anniversary at the show. It's bringing 15 cars from the first three generations to display. "It will be absolutely worth attending the New York Auto Show if you're a Miata fan," Barnes said. That at least hints that there might be something he's not telling us. Otherwise it's a lot of sizzle without much steak.

Mazda CEO says rotary not viable, so don't look for a new one

We have some very sad news to report, rotor-heads fans: Don't expect a new rotary-powered vehicle anytime soon. This comes straight from Masamichi Kogai, the CEO of Mazda, which is the only company to ever market a commercially successful rotary-powered automobile in the world. The issue, as it has pretty much always been, is environmental.
While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of fuel and emitting lots of noxious gases into the atmosphere, at least when running on gasoline. And that means the rotary engine will likely only ever be able to power niche vehicles. And that, in turn, means that it is very difficult to turn a profit on vehicles with rotary engines, particularly for a small automaker like Mazda.
"It has to be a viable commercial proposition. If we are going to adopt it, it has to be a product that can generate at least sales of 100,000 units a year. We have to be able to achieve a profit," said Kogai in an interview with Automotive News. Mazda sold 56,203 RX-7 models in the United States (the automaker's biggest market) in 1986. Sales of the RX-8 peaked in 2004, its first full year on the market, with just 23,690 units.
