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:

RingBanana Miata breaks 9-min Nurburgring barrier

The RingBanana is a cheap Mazda MX-5 Miata on a screaming mission: to lap the Nurburgring in under nine minutes. And let us emphasize the word "cheap." The team wanted the least expensive Miata they could find that still ran, and then wanted to spend the least amount of money possible in order to hit their target mark. We don't know how much they spent on the Ringbanana, but they were so indiscriminate about the purchase that they don't know what year the car is. They only know that it's got 90 horsepower, green springs, Fulda tires, and "it's completely crap." After setting a base lap of 9:21.8 the guys behind the project figured they'd have a fair bit of work. Turns out a new set of Kumho V70A semi-slick, road-legal race tires paired with Gabriel Pirana's driving is all they needed. With just that mod Pirana set a lap time of 8:59.9, and that was while having to deal with one spot of slow traffic that was getting around a stricken car. According to Wikipedia, this puts them between a 2010 Range Rover Sport Supercharged and a 2007 Chevrolet Cobalt SS. Even though the team achieved its goal on its first attempt, the Ringbanana game isn't over – there's probably a suspension mod in the near future while the guys figure out just how quickly they can go. The video above does a good job of showing just how fun it can be driving a slow car fast.
