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 First Drive Review | Defining the term 'fun to drive'

Fun to drive. The phrase gets blasted from seemingly every car commercial, magazine ad, and influencer account – overused that it has lost all meaning. So when Mazda, a small firm that actually does make cars that are fun to drive, talks about their most compelling trait it gets lost in the cacophony of ad spends. However, we're here to tell you that yes, while it's difficult to quantify, some cars are objectively more fun to drive than others, and the all-new 2019 Mazda3 is — and this is a very technical term — a freakin' blast. At Mazda's behest, we took a 2019 sedan up Angeles Crest Highway just outside of L.A. With plenty of yellow signs, tight sequences of banked curves and elevation changes, it's the platonic ideal of those serpentine mountain roads you see in car commercials. The instant the Mazda3 reaches the windy roads, it glides in like an otter diving into the sea. Lively and graceful, it dances along a ribbon of asphalt more naturally than any compact sedan we've driven since the advent of drive-by-wire. The steering is not only direct and true, but possesses an extraordinary ability to maintain trajectory. From the moment you turn in, you never need to make adjustments to the steering wheel until the front tires are straight again. The car goes exactly where you intend, always. That's not hyperbole, but an amazing feat of engineering. In nearly every other vehicle, even those that purport to be sports cars, unless you're incredibly familiar with the machine and know the road like the back of your hand, minor mid-corner corrections are an inevitability. With the 3, you get it right on the first try. Now imagine you're on strip of canyon pavement with lots of short switchbacks in varying radii coming up fast, one right after another. The 3 links them all together with pure ease, and soon you're developing a rhythm through the curves. While other cars charge, the Mazda flows. The car's poise is particularly evident as momentum shifts from one direction to another, what Mazda chassis engineer Dave Coleman termed "transience." In most cars passengers are tossed around the cabin like mannequins, but the 3 cuts out the turbulence, its body engineered to move in a smooth undulation. At the midpoint of the transition, there's even a moment of weightlessness before the car tucks into the next turn and the seat seems to scoop you up and carry you onward.

2016 Mazda CX-3 scores 29/35 mpg EPA ratings

Looking for a subcompact crossover that won't cost you too much at the pumps? Your best bet is now the new Mazda CX-3, according to fuel economy figures released by the EPA. Mazda's new baby crossover has been rated by the US government agency at 29 miles per gallon in the city, 35 on the highway, and 31 on the combined cycle. That's in front-drive spec, giving the CX-3 better fuel economy than anything else in its class (at least, that is, with an automatic transmission.) Option it with all-wheel drive and you'll take a slight penalty at 27 mpg in the city, 32 on the highway, and 29 combined. According to Mazda that still "makes it among the most fuel-efficient all-wheel-drive vehicles available in the US." Whichever drivetrain option you go for, the CX-3 packs a 2.0-liter inline-four with direct injection (Skyactiv-G in Mazda-speak) good for 146 horsepower and just as much torque, mated to a six-speed automatic transmission. The first examples will begin reaching American showrooms later this summer.

As Mazda's first foray into the quickly burgeoning subcompact crossover class of vehicles, CX-3 provides those seeking a purposeful, stylish and sporty vehicle option that bucks convention. CX-3 offers standard keyless ignition and backup camera, and is available with features that are unrivalled in its class like Mazda Radar Cruise Control, adaptive LED headlights and Mazda's signature driving experience. Front-wheel-drive models have EPA-estimated fuel economy of 29 mpg city/35 mpg highway/31 mpg combined, while models equipped with Mazda's predictive i-ACTIV AWD have EPA-estimated fuel economy of 27 mpg city/32 mpg highway/29 mpg combined. That makes it among the most-efficient all-wheel-drive vehicles available in the U.S. "SKYACTIV Technology means we don't have to compromise when it comes to performance, efficiency and fun-to-drive dynamics," said Jim O'Sullivan, president and CEO, Mazda North American Operations.
