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:

2019 Mazda3 sedan and hatchback get IIHS Top Safety Pick awards

The 2019 Mazda3 is all-new, and now we have crash test ratings from the IIHS for both the sedan and hatchback. A Top Safety Pick (not the TSP+) award was given to both variants of the compact car. Since the IIHS only rates the Mazda3 headlights as "Acceptable" and not "Good," it doesn't get the "Top Safety Pick+" rating. All the major crash categories like small overlap front, side and moderate overlap front are rated as Good. The IIHS also makes crash avoidance part of its battery of tests now to evaluate forward collision and pedestrian detection systems. Both versions of the Mazda3 offer these systems, but the IIHS points out that Mazda's "Smart Brake Support" is only standard on the hatchback. This makes the hatchback standard with a "superior-rated" crash prevention system, and only optional on the sedan. Both cars equipped with the system were able to avoid collisions at 12 mph and 25 mph in the IIHS tests. Even though the Mazda3 does come standard with LED headlight projectors, the IIHS still didn't think they were good enough for a Good rating. There is one video of the Mazda3 going through the side crash test if you'd like to watch the new sedan get hit. You can read our thoughts on the new Mazda3 here. We certainly like driving the redesigned Mazda, and it's good to know the car will perform well in a crash, too.

Midsize Sedan Comparison | Honda Accord vs. Toyota Camry vs. Mazda6

The rumors of the midsize sedan's death have been greatly exaggerated. The 2018 Honda Accord and 2018 Toyota Camry together moved more than 262,000 units through May of this year, which is still a ton of cars. Then again, both are down year-over-year despite being completely, and quite impressively, redesigned for 2018. So yes, the midsize sedan's grip on family transportation is weakening. Ford certainly thinks so, yet this change in consumer preferences comes at a time when the current crop of sedans is sensational. They're bigger and more powerful, yet also more efficient. Safety scores are impeccable. They even look better than ever. So before running out to score one of the bajillion little SUVs flooding the market, why not ponder this trio of midsize sedan all-stars that might actually work better? Over the course of three consecutive weeks we tested the 2018 Camry XSE V6, 2018 Accord Touring 2.0T and the perennial critical-darling 2018 Mazda6 Signature. The latter was thoroughly overhauled and, perhaps as such, bucked the segment trend by actually selling more in June this year. Each was a range-topping trim level with all the bells and whistles, plus the most powerful engine available. Really, you couldn't find cars closer in power, price and feature content. View 57 Photos Performance and fuel economy Toyota bucked the turbocharged trend by sticking with naturally aspirated engines for the 2018 Camry, and when it comes to its 3.5-liter V6, it's sure hard to argue with that decision. For starters, it produces 301 horsepower. Let that sink in for a moment. A 301-hp Toyota Camry. That crushes the others, while its 267 pound-feet of torque is only 6 less than the Accord. This is a strong, smooth engine that only gets better when you realize it matches the 26-mpg combined fuel economy of the others. Honda, meanwhile, followed the masses by switching to a turbocharged four-cylinder for the Accord's engine upgrade (and its base engine, for that matter). Though its 252 hp is considerably down on the Camry and its 271 lb-ft is only a smidgen more, the Accord's torque arrives earlier in the rev range without feeling overtly turbocharged. It also has 143 fewer pounds to contend with. When wrung out, this new 2.0-liter belts out a beautiful, typically Honda song made possible by the smart 10-speed automatic (the base 1.5-liter is paired to a CVT that results in more drone than mechanical music) that thankfully doesn't draw much attention to itself.
