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:

eBay Find of the Day: 1990 Mazda Miata with just 27 original miles

Some cars have low mileage, and others have close to no miles at all. This 1990 Mazda Miata, currently listed on eBay Motors and located in Kingman, Arizona, falls into the latter category with only 27 miles on the odometer, according to the seller. But we have to wonder: how did one of the best-driving, most influential sports cars of the past two decades sit without being driven for 24 years? Consider it the seller's loss on this one.
The seller says he bought the car with 20 miles on it, and explains 6.9 miles were added when the car was towed home on a car dolly. It was never registered. Furthermore, the seller says the car didn't come with a set of keys, so he had to have a set made. Though the paint is clean and shiny, the Miata didn't escape minor cosmetic damage over the years, with scratches on the hood, the trunk and the factory hardtop that is included with the car. The front, right fender has a small dent as well, which can be seen in a picture. The seller says the car was stored in a building with windows, so the paint is faded a bit in some places. It's missing its antenna and the battery, and the only non-original parts on the car are the windshield wipers. The clear-title car comes with all paperwork, according to the seller, but, besides the owners manual, he didn't specify what other documentation would be included.
With bidding currently at $10,300 and the reserve not met, this Miata definitely isn't the deal of the century, and we have to question where the value is in this one. The way we see it, it's hard to justify the money if it can't be driven as-is (come on, no battery?), has questionable history, isn't rare and sat in storage for its whole existence. The "weather cracked" tires are probably just the first rubber parts on the car that need to be replaced before it can be driven, but at least the spark plugs were removed and the cylinders were filled with Marvel Mystery Oil prior to storage, which helps to prevent rust and corrosion from forming in the engine.

2019 Mazda MX-5 Miata may be getting 181 hp

Even though the current 2018 Mazda MX-5 Miata makes only 155 horsepower, our experience has shown that it's more than enough fun with its modest output. Still, if Mazda were to offer more, we wouldn't turn it down, and it appears that's exactly what will happen for the 2019 Mazda MX-5 Miata. Road & Track dug up a VIN filing from Mazda to NHTSA with information about the Miata for that model year. On one of the pages, it states that the 2019 Miata will have a 2.0-liter four-cylinder making 181 net brake horsepower. That's a pretty big jump from 155 horsepower, nearly matching the larger 2.5-liter engine in the Mazda3 and Mazda6. It's also close in power to the estimates for the Skyactiv-X spark-controlled compression-ignition engine. But, based on what a journalist on Twitter posted, the 2019 Miata will continue to use a version of the existing spark-ignition Skyactiv-G engine. Apparently it will have a new cylinder head, be able to rev higher, and make more horsepower, though he didn't say how much more. This content is hosted by a third party.

We've reached out to Mazda for comment on this discovery, and, like with most car companies, wouldn't give comment since the topic regards a future product. If it does turn out that Mazda won't up the horsepower for 2019, the good news is that the aftermarket has speed demons covered. Flyin' Miata offers a package that includes camshafts, exhaust and a tune that will bring it up to about 200 hp. There's a supercharger kit from Edelbrock that will provide similar power, but without the need for digging into the engine. Flyin' Miata also offers a turbocharger kit that can bring the Miata up to nearly 250 hp, and if you're really speed-crazed, the company can swap in a Chevy LS V8 with more than 500 hp. Or, you know, you could just be happy with 155. Related Video: Featured Gallery 2016 Mazda MX-5 Miata Club View 32 Photos News Source: Road & Track, Twitter Mazda Convertible Coupe Performance
