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:

Mazda2 refreshed for 2020 with new style and tech

The North American market Toyota Yaris is a badge engineered version of the Mazda 2. Now, the Mazda underneath the Toyota badging has received some updates in its home market of Japan, and it will be interesting to see if or when the U.S. counterpart will be refreshed with any of these updates. The 2020 Mazda 2, now indeed called "Mazda 2" instead of the older Demio name on the Japanese market, has received new front end styling to bring it in line with bigger Mazda models. The grille and bumper are new, as are the headlights with adaptive LED technology and LED daytime running lights. Apparently the headlights are constructed out of 20 individually controlled LED blocks to optimize light output and direction, which sounds awfully interesting for this class of vehicle. The front end design, just like the new 16-inch alloy wheels, is Mazda-specific and the Yarisized version is unlikely to benefit from them, especially since the headlights are also different on the Toyota. Cabin materials have also been updated, and the driver’s seat is available with six-way power adjustability for 2020. The MZD Connect infotainment has Apple Carplay and Android Auto support, like the Yaris setup. In addition, cabin comfort is said to have been improved with better soundproofing, which is sometimes sorely needed in this class of cars. Safety and convenience features include adaptive cruise control, which is impressive on a city car, and the Mazda 2 also has the G-Vectoring Control Plus system for high-speed stability. Both the diesel and gasoline versions will get Mazda's i-Eloop brake energy regeneration system. The Japanese market also gets an all-wheel-drive version, which is surely a hoot despite only being available with the automatic transmission. CarAdvice says the Australian market will receive the redesigned Mazda 2 early next year, which is probably in line with the rest of the global market that gets it as a Mazda instead of a Toyota; Mazda says Japan market pre-orders have started today and official sales will begin on September 12th. It pays to remember that the base car dates back to 2014, and that the 2020 refresh is a facelift instead of a ground-up redesign. Assuming the usually expected shelf-life for the facelifted edition, the 2 will have racked up respectable mileage from the “DJ” generation bodyshell.

Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.
