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 still really wants to bring diesels to America

Mazda's Skyactiv program has delivered much of what it promised for the brand's latest crop of products, namely great fuel economy and excellent driving dynamics. However, the Skyactiv diesel engine has yet to reach our shores. It's been promised ever since the new Mazda6 showed up here for the 2014 model year. According to a new report from Automotive News, Mazda's CEO Masamichi Kogai said that the Mazda Skyactiv D diesel powertrain is still set to make an American appearance. He told Automotive News that there is an internal timeline to get it to the States, and while he didn't reveal the timeline, he said he wants it to come here before he steps down as CEO. The powertrain is offered elsewhere, so it fits in the company's current vehicles, but the US has specific regulatory hurdles, and the engine's extra cost has to make sense from a sales and volume perspective. We doubt VW's diesel scandal helped the engine's sales pitch, either. Automotive News also reports that the next generation of Skyactiv designs and engines are also on their way and will advance and improve on the current generation's strengths. Engineers revealed to Automotive News that they expect a 30 percent improvement in efficiency and are developing an engine with the sky-high compression ratio of 18:1. This impressive ratio could be a further indication of Mazda's pursuit of homogenous charge compression ignition (HCCI) engines. Mazda has had plenty of success with its strategy of making very efficient internal-combustion engines, but there are some concerns that the company can only improve so much. The main worry comes from the company's lack of investment in hybrid and electric powertrains. Even Mazda's North American CEO Masahiro Moro expressed concern about meeting a 54.5 mpg mandate for 2025. That mandate will no longer take effect, but increasing fuel economy requirements will always be an issue. Related Video:

Mazda halts Mazda3 sales for fuel tank problem

Mazda is issuing a stop sale and recall on 14,406 examples of the 2015-2016 Mazda3 in the US with build dates between May 21, 2015, and August 24, 2015, due to a possible fuel leak. There are no reports or accidents or injuries from this problem. According to the company, a defective fuel shut-off valve can allow gasoline to move from the tank and fill the charcoal emissions canister. If it gets too full, there can be a leak, which obviously carries the risk of a possible fire. The engine might stall, as well. Affected owners will be notified to bring their Mazda3 in "as soon as possible." Dealers will inspect the vehicles, and if a problem is found, the fuel tank and charcoal emissions canister will be replaced. During the downtime, customers will get a free rental or loaner car, as well. Those who are particularly concerned can also call Mazda roadside assistance to have their vehicle delivered for the check and possible repair.

A defect in the fuel shut-off valve may allow fuel to flow from the fuel tank into the charcoal emissions canister. With this condition, the check engine light may illuminate, and if the fuel exceeds the canister capacity, fuel leakage could occur, increasing the risk of a fire and/or engine stalling. Approximately 14,270 vehicles in the U.S. and 136 vehicles in Puerto Rico are affected. Owners of subject vehicles will be notified by mail in early October. They will be informed to bring their vehicle to the nearest Mazda dealer as soon as possible. Dealers will inspect the fuel tank to determine if the defect exists on the vehicle. If the defect exists, the dealer will replace the fuel tank and charcoal canister at no cost to the customer. A rental or loaner vehicle will be provided at no cost to the owner, until the vehicle is repaired for this concern. If there are no concerns, the vehicle will be returned to the customer. Should a customer not want to drive the vehicle to the dealership, they may contact Mazda's 24-hour Roadside Assistance service at 800-866-1998 and have the vehicle picked up and delivered to the dealership. There have been no reports of accidents or injury related to this issue.
