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 rotary engine returning in 2019 as EV range extender, exec says

It seems that a range-extended Mazda electric car with a rotary engine is for real, and coming sooner than expected. An automotive news outlet from the Netherlands called AutoRAI spoke with Mazda's European vice president for sales and customer service. He told the outlet that Mazda has an electric car coming In 2019, and it will be available with a rotary engine as a generator. Among the details about this car and its powertrain, he said it would be similar in size to the Mazda3, and it might even be a crossover. It will also be based on Mazda's upcoming modular small car platform. The rotary engine will only generate electricity and will only have one rotor. Not only that, it will be mounted horizontally. This is particularly unusual as every rotary Mazda has had the engine mounted upright. We've reached out to Mazda representatives in the U.S. and Europe. An American representative couldn't comment on what type of range-extender options may be coming in the future. We say this specifically because Mazda has confirmed previously that an EV with an available range extender is coming in 2019. We have not heard back from a European representative at the time of publishing. Despite this, a return of the rotary as a range extender looks probable. Besides the dates fitting with Mazda's electric plans, there are other tidbits from the past that support the idea. Mazda has been experimenting with the idea for years, and even created a functioning Mazda2 EV with a rotary range-extender. The company has also filed patents in the U.S. for the setup as recently as last year, and there have been other recent rumors.

2019 Mazda3 Hatchback AWD Premium Second Drive | Gushing about an exceptional car

The 2019 Mazda3 Hatchback is quite simply one of the best cars I've ever driven. During my week with one, specifically a range-topping Premium package version for $31,335, I struggled to come up with bad things to say apart from elements like rear visibility and back seat headroom that are directly related to its distinctive, avant garde design. That's an acceptable tradeoff in my book. So many of the new 3's elements can serve as a measuring stick for other cars. Not just its specific compact hatchback/sedan class, but all other cars, period. I had the Mercedes CLS 450 at the exact time, a car I deeply appreciate and that cost $69,000 more, and yet it was a struggle to decide which I wanted to drive. Perhaps not surprising given the 3's history, but the measuring stick is set first by the handling. It dances between corners with composure and feedback that you just don't get in cars any more ͖ let alone at this price point. This is a car you feel through your butt, your heels on the floor and your hands on the wheel. Everything is just so right. And it should be noted that I came to this conclusion before remembering that Mazda switched to a cheaper, less sophisticated torsion beam rear suspension for this latest model. Perhaps you can tell the difference driving 10/10ths at a test track, but in the real world, I certainly didn't notice or log a complaint. Grip is superb. Even when the tires gave way a bit on my mountain road evaluation route, there was only a bit of squealing and it resolutely whipped itself through hairpins with shockingly little understeer for a front-drive-based car, helped no doubt by its all-wheel drive system. It would be interesting to see how much understeer the front-drive versions allow, and whether AWD is mitigating torque steer given the 3's not-insignificant power. As it is, the 3's standard 2.5-liter four-cylinder produces 186 horsepower and 186 pound-feet of torque, which is substantially better than virtually every other base engine in the segment. Its throttle response should be copied by everyone, as should the steering. OK, maybe not Porsche, which I keep finding myself drawing comparisons to whenever experiencing a new Mazda. Take that as the compliment it seems to be. I'd also like to note that the 3 has a six-speed automatic transmission rather than an easily confused eight-, nine- or eleventy-speed unit. Or a damn CVT.
