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:

Mazda 3 Sedan and Hatchback Luggage Test | Trunk comparison

A major reason for buying a hatchback is for added cargo space and versatility, right? Seems logical enough. It's certainly a reason I've been fond of them over the years. And since so many SUVs these days are just glorified hatchbacks, it certainly stands to reason the buying public has reached this conclusion as well. To test this hypothesis and potentially bust this myth, Mazda kindly provided three vehicles that are virtually identical apart from their body style: the Mazda 3 sedan and hatchback, as well as the Mazda CX-30 crossover that's really just a raised and rebodied 3.  On paper, in descending order, the CX-30 is tops at 20.2 cubic feet of space behind the back seat, the Hatchback has 20.1 cubic feet and the sedan has 13.2. OK, let's see how the order turns out once luggage is used. Here is the 3 Hatchback on the left and 3 Sedan on the right. Immediately, the sedan doesn't look that much smaller than the Hatchback. Actually, doesn't it look bigger? Below is the CX-30.  Note that this CX-30 did not include its rigid cargo cover, but already, you can start to see the difference between 3 Hatch and CX-30. The crossover has more space above the back seat line than the Hatchback. So, even if the 3 Hatch has more cargo area length, the CX-30 has more height. That's why you have virtually equal cargo capacity numbers despite having different spaces.  To that point, let's bring in the bags. As in every luggage test I do, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). CX-30 for the win (above right) as all the bags fit. The fancy bag and smaller roller are slightly blocking the rearward view, but you can still see out and the bags won't fly forward. Importantly, they also fit when closing the CX-30's hatch. They won't if you attempted the same formation in the 3 Hatchback, which can't fit the fancy bag or one of the midsize rollers. And no, you can't fit the fancy bag in the middle there — the hatch wouldn't close on top of it. A smaller duffel will, however.  So, although the 3 Hatch has a slightly longer space, the difference doesn't matter as much as the CX-30's extra height in this usage case.

Mazda LM55 Vision Gran Turismo reshapes a winning form [w/video]

In the history of endurance racing, there's only ever been one Japanese automaker to win the famous 24 Hours of Le Mans, and as you might have guessed, that was Mazda in 1991 with the 787B – which was, incidentally, the only one ever to win the race under rotary power, or really anything other than a conventional piston engine. That racing success is something Mazda can be proud about, even over two decades later, and it's a badge of honor the automaker is revisiting with the LM55 prototype you see here. Only instead of unleashing it on the Circuit de la Sarthe – or really any actual race track – the Mazda LM55 Vision Gran Turismo is bound only for PlayStation. The latest addition to the Vision Gran Turismo lineup, the LM55 takes inspiration from the aforementioned 787B but gives it a modern KODO design theme. The result is pretty stunning, taking a more radical approach than the Skyactiv Prototype the company is fielding in the United SportsCar Championship or even the dearly departed, head-turning Furai concept. But unlike that diesel prototype and the Wankel-powered 787B, Mazda hasn't specified any kind of novel powertrain for the LM55, fictitious or otherwise - saying only that it has "advanced drive train technology that offers the epitome of power, efficiency and durability and the result is an exceptional power to weight ratio exceeding that of most cars in its class." Just what that class would be we'll likely never find out, but if you don't have a PS3 loaded with GT6 (or, for that matter, even if you do), you can scope out the virtual action in the slideshow above and the rather Christmas-y video below.
