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:

Stock Miata beats bunch of high-powered cars in wet 1/4-mile drag race

When is a stock, 167-horsepower Mazda MX-5 Miata quicker than a Chevrolet Corvette, Ford Mustang, Lamborghini Gallardo, Lotus Elise and a Porsche 911? When it's raining. Sort of.
Mazda Canada arranged a unique drag race to show off the fact that the Miata's optional power retractable folding hardtop can go from top-down to top-up in just 12 seconds flat. In this video, all six cars line up for a drag race, and it starts to rain (well, sort of - but you'll have to watch the video all the way to the end to see what we mean). The green flag is waved, and the timer starts as soon as the convertibles begin to put their tops up. But because the Miata's roof mechanism gets the car's roof back up a full 5.1 seconds quicker than the second-place car, the Mazda gets a serious advantage off the line for the actual drag race.
It's a fun video. And while we've spoiled the results (come on, the video was uploaded by Mazda, you knew the Miata was going to win), be sure to see how it all unfolds, below.

2018 Mazda6 Wagon: Beautiful but forbidden

Mazda has finally revealed the updated Mazda6 wagon it announced a few weeks ago. It's just as beautiful as we expected. The exterior features most of the same updates as the sedan version. They include a grille with more depth and dimension, a cleaner lower fascia, and headlights that are more integrated with the grille. Inside, the dashboard has been revised to look less cluttered, and the high-end leather and suede trimmings of the Signature trim are available. View 12 Photos Of course, the 2018 Mazda6 wagon still won't be available in America. And that's particularly disappointing, especially for this author, because the car looks so great. But we do understand the reasons why. Nobody buys wagons, at least without plastic body cladding on them. Plus, Mazda already offers the CX-5 here in the United States, and it serves effectively the same purpose, but in a much more popular crossover package. Seriously, the CX-5 is Mazda's best-seller over the last two months, selling more than twice as many as the next best-seller, the Mazda3. But there's still a silver lining to our lack of a wagon. You see, a close examination reveals that while the European Mazda6 sedan and wagon get most of the same updates as those in the American market, they won't get the 250-horsepower, 310 pound-feet of torque-producing turbocharged 2.5-liter gasoline engine we're getting. And given a choice, we would probably prefer more power than a wagon variant. The most potent engine over in Europe will remain the diesel 2.2-liter engine making 181 horsepower and 328 pound-feet of torque. Related Video: This content is hosted by a third party.
