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:

2016 Mazda MX-5 Miata First Drive [w/video]

Hypothetically speaking, if you blindfolded me, put me in the car pictured above, and told me to hit the road, it would have taken me maybe two minutes to figure out that I was driving the 2016 Mazda MX-5 Miata. There are just certain facets about Miata driving that have been baked into every generation of Mazda's roadster, and it makes for a symbiotic relationship between car and driver that's truly unique. Sure, I could rattle off a list of cars that come close to offering the same sort of experience, but they just can't quite capture the same intrinsic Miata magic. Mazda knows its Miata is an incredibly special machine. Listening to the company's engineers and designers talk about the development of this fourth-generation ND model is fascinating. The attention to detail is astonishing, and every single person involved in the Miata program knows that the most important goal is to keep this car as true to its predecessors' ethos as possible. It cannot just be a great convertible, or even a great Mazda – it has to be a great MX-5 Miata. But the company did not just want to improve upon the third-generation NC Miata, which has been around since 2006. They wanted to tie the ND Miata's roots back to the original NA from 1989. Back in '89, the Miata was a less-powerful, 1.6-liter model with 115 horsepower and 100 pound-feet of torque. Mazda's team said they are proud of every version of the MX-5, but it's this specific, first-generation model that the company calls the "most right" – the most true to the idea of what a Miata ought to be. So that's why, before being allowed to attack the winding roads of the Spanish countryside in the 2016 MX-5, Mazda wanted me to spend some time with a cherry example of the original NA Miata: a Mariner Blue darling that, even with some 239,000 kilometers on its clock, still felt absolutely impeccable from behind the wheel. Light, responsive, and perfectly balanced, it was the original embodiment of the harmony between driver and car that Mazda wanted in every Miata. Mazda executives said they felt the first Miata was also the right size. So they chopped off three inches on the ND compared with the NC, and put it on a wheelbase that's been reduced by six-tenths of an inch. In fact, these dimensions mean the new Miata is more than two inches shorter in length than the original, and only two-tenths of an inch taller. In this day and age of ever-expanding waistlines and footprints, it's a remarkable achievement.

Mazdaspeed2 supermini hot hatch under consideration

Though the Ford Fiesta ST and Fiat 500 Abarth (and arguably the Mini Cooper S) may stand pretty much alone in the North American market, in overseas markets, supermini hot hatches are a big deal. Unfortunately, challengers like the Volkswagen Polo GTI, Seat Ibiza Cupra and Renault Clio RS 200 Turbo never make it to our showrooms, but word has it that there's soon to be a new entry on the market.
That would be the Mazdaspeed2, which would be badged in certain markets as the Mazda2 MPS. Speaking with Australian site CarAdvice.com.au at the launch of the Mazda2 on which it would be based, the Japanese automaker's global sales chief and the hatchback's deputy product manager hinted that such a product is definitely being discussed, even if it hasn't yet been approved.
This wouldn't be the first time such a notion were entertained, as Mazda has shown numerous performance concepts based on the previous Mazda2/Demio over the years, but none have come to fruition.
