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:

2014 Mazda6 earns Popular Mechanics' 'Car of the Year'

Ring one up for Mazda. The Japanese brand's midsize offering, the Mazda6, has been named Popular Mechanics' Car of the Year. The 6 received a comprehensive reworking for the 2014 model year that saw it adopt sleek, sexy sheet metal; a clean, logical interior; and powertrain technologies that allow it to net some of the best fuel economy available in a gas-powered, non-hybrid sedan.
Popular Mechanics praised the 6's Skyactiv 2.5-liter, 184-horsepower engine, as well as its agility and responsiveness during testing. It also remarked on the functional, but well designed cabin, and the degree of available technology.
"The Mazda6 really impressed us with how well it delivers so many things modern car owners want: great mileage, fun road-handling, upscale features and looks - and remarkable value," said Jim Meigs, Editor-in-Chief of Popular Mechanics.

Mazda RX-Vision GT3 concept slinks into Gran Turismo Sport next year

The World Final of the FIA World Tour in Gran Turismo Sport just went down in Monaco, and Mazda was there with a couple of big announcements. The first is that the Hiroshima-based automaker will become an official video game partner next year, 2020 also happening to be Mazda's centenary year. The second reveal was a sketch of the Mazda RX-Vision GT3 Concept, a GT3-class racer based on the RX-Vision Concept shown at the 2015 Tokyo Motor Show. Game creator Kazunori Yamauchi and Mazda's North American design chief Julien Mountousse wouldn't get into details, such as how close the final car would look to the drawing or whether there'd be a rotary engine under the hood. Yamauchi would only say Polyphony Digital is modeling the car right now, and Montousse added that designers wanted the Vision GT3 to be a car players really wanted to drive. As much of a looker as the race car is, it's clear some changes will be in order; the front fenders, roof, and rear wing are nearly on the same plane. The brunt of aero accessorizing happens down low, a massive front splitter leading to extended side sills with vertical planes, and what must be a massive rear diffuser with an even larger set of vertical planes. It's hard to tell by the drawing, but it looks like the rear wing supports angle out from the body to merge with the end plates. When the RX-Vision GT3 shows up to contest the 2020 FIA-certified championships in GT Sport, it will join the Atenza Gr.3 as Mazda's only GT3-class car in the game — the Atenza effectively a near copy of the Speed Source Mazda6 that raced in the U.S. Grand-Am series until a couple of season ago, but with four doors instead of two, and a gas engine instead of diesel. Mazda didn't qualify for the GT Sport Manufacturer's Cup this year, they'll be hoping their team can change that next year with the RX-Vision GT3 since, as Montousse said, "That car has all the Mazda spirit in it." There will be more coming from Mazda in GT Sport as well. Word is that the official partnership won't stop at a single new car, and Yamauchi remarked on the partnership, "I think we can keep our expectations high for next year." Fast forward to 17:50 in the video to see the sketch presented, or roll back a bit to 14:00 to listen to comments from Mazda global head of design Ikuo Maeda.
