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:

A tough choice: 2017 Honda CR-V vs. 2017 Mazda CX-5

One has to feel for the typical new-car buyer. The one not reading Autoblog and the one who recognizes a V8 as vegetable juice. For them, picking between compact crossovers must seem like choosing between various identically sized cardboard boxes. Which one do you want? "Ah, I'll take the one with the best deal." Except, with the 2017 Honda CR-V and now the 2017 Mazda CX-5, Joe P. Everyman has a chance to choose between two vehicles that are quite clearly different, yet also clearly leaders in what they do. Everything else seems like alternatives based on price or perhaps off-road readiness (Jeeps Compass and Cherokee, perhaps a Subaru Forester). As scheduling would have it, a 2017 CR-V Touring just happened to be sitting in my garage the week I was set to drive the new CX-5 Grand Touring in San Diego. This isn't a complete, scientifically enacted comparison test, but there was enough drive time in close succession on the same roads and with similar price tags to draw conclusions. At its simplest, the CX-5 is the best choice for the driver while the CR-V is the best choice for everyone else aboard. That's not to say they are myopic in those classifications – the CX-5 could still ably handle family duty, while the CR-V is impressively well-rounded to drive in a way that shouldn't turn off those seeking some driving involvement. However, each has a clear focus that sets it down a different path toward different target buyers. Let's start with the newer kid on the block from Mazda. It is best suited for the person whose life changes have dictated the switch from an agile car to some sort of family hauler. Its spot-on steering and throttle response evoke Porsche, while the six-speed automatic transmission favors performance over fuel economy (while still getting really good fuel economy). Those dynamic elements, plus a carefully crafted, ideal driving position should make the CX-5 feel "just right" for those used to more sporting, non-family-oriented transport. Inside, the latest CX-5 boasts a handsome, upscale design with materials to match. Aesthetically, to these eyes at least, it's the best of a crowded bunch. Quality-wise, only the also-impressive CR-V would seem to come close. Along with the slick new exterior, the cabin conveys the more premium vibe that Mazda was shooting for with the new CX-5 – it also makes a more emotional connection than the typical cardboard box on wheels.

Mazda still really wants to bring diesels to America

Mazda's Skyactiv program has delivered much of what it promised for the brand's latest crop of products, namely great fuel economy and excellent driving dynamics. However, the Skyactiv diesel engine has yet to reach our shores. It's been promised ever since the new Mazda6 showed up here for the 2014 model year. According to a new report from Automotive News, Mazda's CEO Masamichi Kogai said that the Mazda Skyactiv D diesel powertrain is still set to make an American appearance. He told Automotive News that there is an internal timeline to get it to the States, and while he didn't reveal the timeline, he said he wants it to come here before he steps down as CEO. The powertrain is offered elsewhere, so it fits in the company's current vehicles, but the US has specific regulatory hurdles, and the engine's extra cost has to make sense from a sales and volume perspective. We doubt VW's diesel scandal helped the engine's sales pitch, either. Automotive News also reports that the next generation of Skyactiv designs and engines are also on their way and will advance and improve on the current generation's strengths. Engineers revealed to Automotive News that they expect a 30 percent improvement in efficiency and are developing an engine with the sky-high compression ratio of 18:1. This impressive ratio could be a further indication of Mazda's pursuit of homogenous charge compression ignition (HCCI) engines. Mazda has had plenty of success with its strategy of making very efficient internal-combustion engines, but there are some concerns that the company can only improve so much. The main worry comes from the company's lack of investment in hybrid and electric powertrains. Even Mazda's North American CEO Masahiro Moro expressed concern about meeting a 54.5 mpg mandate for 2025. That mandate will no longer take effect, but increasing fuel economy requirements will always be an issue. Related Video:
