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:

IIHS Top Safety Pick and Top Safety Pick+ awards get tougher: Here are the latest winners

Automakers love to trumpet the accolades from the Insurance Institute for Highway Safety, but the agency keeps making its best grades harder to achieve. For 2020, it is raising the bar again, requiring a better score in the passenger-side small-overlap crash test, wider availability of top-performing headlights, and automatic emergency braking systems that effectively avoid collisions with pedestrians, in addition to its previous benchmarks. Why the 2020 criteria is harder: To be named either a Top Safety Pick or Top Safety Pick+, the required performance in the passenger-side small-overlap crash test has been raised from Acceptable to Good, meaning that the model must achieve Good ratings in all crash tests. The Nissan Rogue, for example, scored an Acceptable in the passenger-side small overlap crash, and so it loses its Top Safety Pick rating for 2020. To achieve either of the top ratings, a vehicle's automatic emergency braking system must effectively avoid hitting pedestrians as well as other vehicles. (The automatic emergency braking system can be optional, but then the award applies to the model only when so equipped.) Any vehicle whose automatic emergency braking system does not include pedestrian detection would lose its TSP or TSP+ rating for 2020, the Ram 1500 being one example. To be named a Top Safety Pick+, the model can have no variant with headlights that achieve less than an Acceptable rating (most new cars have different headlights — often LEDs — that are exclusive to upper trim levels).

Driving a $500 junker in a 500-mile off-road rally race | 'The List' #0500

Jessi and Patrick have done some insane rally races on "The List," but in an effort to continually out-do themselves, this might be the craziest yet. It's called the Gambler 500, and the idea is that 2,000-plus participants take $500 cars and drive them 500 miles across Oregon, mostly off-road. It's a maniacal mishmash of cars with not enough doors, too many doors, airplane wings strapped to the tops, graffiti'd cartoons on the hoods, stuffed animals hanging out the windows — you get the idea. Our hosts start the race with an absolutely epic Mazda Miata sitting atop super swampers. It didn't have a top, but have no fear because it had a roll cage, so ... that's better? Unfortunately though, they didn't have time to customize the car fully to their liking before the race, so the first stop after the starting gun was naturally a garage sale for some knickknacks to give the car a little more flair. One of the defining aspects of the Gambler 500 is having the most obnoxious, bonkers car possible, and the old Miata needed a bit of a kick in the ass. Thankfully, the crew found the largest teddy bear in existence, strapped that bad boy to the roll cage, and they were on their way. There are a few routes you can choose to take in the Gambler 500, and our crew chose the most challenging, called "The Devil's Butthole." A hilarious name for an outrageously fun route, it's definitely not one that many Miatas have likely tackled. And therein lies the gamble: Will they make it to the end? As always, you'll have to watch the episode above to find out.
