Ford and Samsung’s new lithium-ion battery may send lead-acid units to the scrap heap

By Andrew Hard Published June 4, 2014

The lead-acid car battery was invented in 1859 by French physicist Gaston Planté, and if you pop open the hood of your car right now, you’ll probably see something very similar to his first prototype. For all the advancements cars have made over the years, its batteries have remained eerily unchanged.

This Tuesday, Ford and technology mogul Samsung announced a dual-battery system for gas-powered vehicles that could be the beginning of the end for the lead-acid battery.

Ford and Samsung have combined a lithium-ion battery with a 12-volt lead-acid unit, creating a new, lighter, and more flexible power source. The new concept has massive potential for fuel savings, as the lithium-ion component can be recharged through regenerative braking.

Regenerative braking, which has only been available on hybrid and electric vehicles thus far, recovers kinetic energy from the brakes and uses it to charge a vehicle’s batteries. Since this energy is normally converted into waste heat and friction, implementing this process on non-hybrid vehicles seems like a no-brainer.

Ford isn’t stopping with new battery technology, though. Other fuel-saving technologies like Auto Start-Stop, which shuts off a car’s engine at stoplights, could ensure that Ford’s gas-powered vehicles of the future may be just as fuel-efficient as the hybrids of today.

“We are currently expanding our Auto Start-Stop technology across 70 percent of our lineup, and this dual-battery system has the potential to bring even more levels of hybridization to our vehicles for greater energy savings across the board,” explains Ted Miller, senior manager of Energy Storage Strategy and Research at Ford. “Although still in research, this type of battery could provide a near-term solution for greater reduction of carbon dioxide.”

Given that lithium batteries are lighter, more compact, and have more recharging options than their lead-acid counterparts, it’s hard to see why that bulky, toxic unit under your hood won’t be going to way of the dinosaurs pretty soon.

Ford and Samsung say that they’ll continue their partnership to develop more advanced lithium-ion units in the future, which could potentially make the traditional lead-acid battery obsolete.

No offense to Gaston Planté, but it’s about time.

Jeep Compass EV breaks cover—but will it come to the U.S.?

Jeep just pulled the wraps off the all-new Compass EV, and while it’s an exciting leap into the electric future, there's a catch—it might not make it to the U.S. anytime soon.
This is a brand new electric version of the Jeep Compass, and being built on Stellantis' STLA platform—the same architecture underpinning models like the Peugeot E-3008 and E-5008—it looks much slicker and packs a lot more inside than previous versions of the Compass.
Let’s start with what’s cool: the new Compass EV is packing up to 404 miles of range on a single charge, a 74 kWh battery, and fast-charging that gets you from 20% to 80% in about 30 minutes. Not bad for a compact SUV with Jeep's badge on the nose.
There are two versions: a front-wheel-drive model with 213 horsepower and a beefier all-wheel-drive version with 375 horsepower. That AWD setup isn’t just for looks—it can handle 20% inclines even without front traction, and comes with extra ground clearance and better off-road angles. In short, it’s still a Jeep.
The design's been refreshed too, and inside you’ll find the kind of tech and comfort you’d expect in a modern EV—sleek, smart, and ready for both city streets and dirt trails.
But here’s the thing: even though production starts soon in Italy, Jeep hasn’t said whether the Compass EV is coming to America. And the signs aren’t promising.
Plans to build it in Canada were recently put on hold, with production now delayed until at least early 2026. Some of that might have to do with possible U.S. tariffs on Canadian and Mexican vehicles—adding a layer of uncertainty to the whole rollout.
According to Kelley Blue Book, a Stellantis spokesperson confirmed that the company has “temporarily paused work on the next-generation Jeep Compass, including activities at” the Canadian plant that was originally meant to build the model. They added that Stellantis is “reassessing its product strategy in North America” to better match customer needs and demand for different powertrain options.
So while Europe and other markets are gearing up to get the Compass EV soon, American drivers might be left waiting—or miss out entirely.
That’s a shame, because on paper, this electric Jeep hits a lot of sweet spots. Let’s just hope it finds a way over here.

Tesla just scrapped the Cybertruck range extender

Tesla CEO Elon Musk behind the wheel of a Cybertruck.

The writing was pretty much on the wall for the Cybertruck range extender last month when Tesla removed the option from its website. Now, it’s officially scrapped it and is refunding the $2,000 deposits that customers put down for the $16,000 battery pack.

“We are no longer planning to sell the range extender for Cybertruck," Tesla said in a message to customers on Wednesday, adding, "As a result, we will be refunding your deposit in full.”

Zoox recalls robotaxis after Las Vegas crash, citing software fix

Amazon's self-driving vehicle unit, Zoox, has issued a voluntary safety recall after one of its autonomous vehicles was involved in a minor collision in Las Vegas. The incident, which occurred in April 2025, led the company to investigate and identify a software issue affecting how the robotaxi anticipates another vehicle’s path.
The recall, affecting 270 Zoox-built vehicles, was formally filed with the National Highway Traffic Safety Administration (NHTSA). Zoox said the issue has already been addressed through a software update that was remotely deployed to its fleet.
Zoox’s robotaxis, which operate without driving controls like a steering wheel or pedals, are part of Amazon’s entry into the autonomous driving space. According to Zoox’s safety recall report, the vehicle failed to yield to oncoming traffic while making an unprotected left turn, leading to a low-speed collision with a regular passenger car. While damage was minor, the event raised flags about the system’s behavior in complex urban scenarios.
Establishing safety and reliability remain key factors in the deployment of the relatively new autonomous ride-hailing technology. Alphabet-owned Waymo continues to lead the sector in both safety and operational scale, with services active in multiple cities including Phoenix and San Francisco. But GM’s Cruise and Ford/VW-backed Argo AI were forced to abandon operations over the past few years.
Tesla is also expected to enter the robotaxi race with the launch of its own service in June 2025, leveraging its Full Self-Driving (FSD) software. While FSD has faced heavy regulatory scrutiny through last year, safety regulations are expected to loosen under the Trump administration.
Zoox, which Amazon acquired in 2020, says it issued the recall voluntarily as part of its commitment to safety. “It’s essential that we remain transparent about our processes and the collective decisions we make,” the company said in a statement.
