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:

Mazda spiders return, 42k Mazda6 sedans recalled for webby fuel tanks

It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine.
According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations.
So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month. Scroll down below for the statement from Mazda, along with the official recall notice from the National Highway Traffic Safety Administration.

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.
