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:

2019 Mazda CX-9 Review and Buying Guide | Fun for the whole family

The 2019 Mazda CX-9 crossover is the biggest vehicle in the Japanese automaker's lineup, and the only one to offer a third row of seating. It has only one powertrain option, but offers a wide variety of other content across various trim levels. Many folks are drawn to Mazdas for their elegant design, affordability and driving dynamics that are sharper than most, and the CX-9 has all of that to a certain degree even if it's the biggest, most family-oriented one. Still, the CX-9 may be big for a Mazda, but it's one of the smallest in its segment in terms of third-row space and cargo capacity, so it may not be for every family. What's new with the Mazda CX-9 for 2019? Though largely unchanged from when this generation debuted for the 2016 model year, the Mazda CX-9 gets a few small changes for 2019, the biggest of which is the addition of Apple CarPlay and Android Auto compatibility, which is optional on its lowest Sport trim and standard on the Touring, Grand Touring, and Signature. The transmission has been retuned for a smoother, quieter driving experience. Thicker floor mats and headliner further help to make the car quieter. Each trim gets a little something new, too. Sport now offers an optional Sport Package, costing $1,290, with heated front seats, a power driver's seat, heated mirrors, lane-keep assist, adaptive cruise control and automatic emergency braking. Moving up to the Touring trim, the only other change is a frameless rear-view mirror. The Grand Touring trim gets a new 7-inch info screen in the instrument panel, along with new power-folding side mirrors and a 360-degree camera system. The top-level Signature trim gets new badges, rosewood interior trim, and accent lighting in the grille and around the shifter. Along with the new features, the CX-9 increases in price. The Sport trim costs a mere $150 more, the Touring and Grand Touring trims go up by $370, While the Signature jumps $1,050 compared to the 2018 model. What are the CX-9's interior and in-car technology like? The interior varies by trim level, but with Mazda making moves to grab customers from some of the luxury brands on its "path to premium," the higher grades do look and feel like a high-quality, comfortable place to spend time. It's a spacious interior with room enough for a third row. There are some rally nice materials in use, depending on the trim level, including Nappa leather and something called Santos Rosewood.
