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 CX-5 Luggage Test | How much cargo space?

We're already seen how Mazda's largest crossover, the CX-9, does at stuffing luggage inside its cargo hold. Now it's time for the next rung down the Mazda ladder. The Mazda CX-5 has 30.9 cubic-feet of space behind its raised back seat, which on paper, is considerably less than its top competition. The Hyundai Tucson leads the way with 38.7 cubic-feet, the Honda CR-V (39.2) and Toyota RAV4 (37.5) are basically the same, and the Subaru Forester has between 33 and 35 depending on options. However, the CX-5 does have more than the Chevrolet Equinox (29.9), Jeep Compass (27.2) and Ford Escape when its sliding back seat is in its aft-most position (33.5 when all the way forward).  Basically, this compact Mazda's cargo area is midpack, which makes it a good choice for my first luggage test of the segment. Let's see how much of the luggage in my garage fits inside. As a refresher, I use two mid-size 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).  I started by keeping the cargo cover in place to see how much fits underneath it. The answer is the four largest bags. The two smaller ones did not. OK, now let's remove the cargo cover, which is an unusual design. Rather than a roller-type cartridge that you manually pull into place or a rigid hatchback-like unit that rises up when the liftgate goes up, the CX-5 basically combines the two. The forward bit is attached to the liftgate and unspools when opened.  To detach it, you need to unfasten these plastic clamps and then remove the cartridge reel much as you would a normal cargo cover. OK, and now here's how much the CX-5 can fit with the cargo cover removed.  All of it! That above configuration is just the first thing I came up with, but there's likely additional Tetris formations to be found. Note that the tailgate does close here but the middle cases' wheels are awfully close to the window.  I'm not going to stop there, though. I went ahead and rummaged through my garage to see what it would take to fill'er up. There you go: one duffle bag and one gym bag stuffed into the spaces. You could probably fit a grocery bag right in front there, too.

Mazda MX-5 breeds upgraded Roadster RS in Japan

Fans of the new Mazda MX-5 Miata looking for something a little more performance-focused may be enticed by the new RS model. Unfortunately they'll have to go all the way to Japan to get it. Because Mazda will only be offering this particular version back home. The new RS version of the Mazda Roadster (as it's known in Japan) features a number of performance upgrades, although none of them specifically affect the engine or its output. The Roadster RS features Bilstein dampers and front suspension tower brace for better handling, along with bigger brakes for added stopping power, a retuned steering rack for sharper turn-in, and upgraded exhaust for a better sound. Inside it's also been treated to heated Recaro seats with Nappa leather and Alcantara trim and a nine-speaker Bose audio system. It also comes equipped with adaptive front lighting and high-beam control as well as lane-departure and blind-spot warning systems. Feeling left out yet? Don't be too disappointed, or book that ticket to Tokyo's Natita International Airport just yet. The Mazda Roadster RS only comes with the smaller 1.5-liter engine that produces 129 horsepower, which is significantly less than the 2.0L we get here at 155 hp. It does, however, come with the six-speed manual instead of the automatic. So while this may not be the most powerful version of the Miata, it may be the enthusiast favorite – at least in the JDM.
