Stellantis Starts Road Testing Solid-State Dodge Charger Daytona

Stellantis announced on June 11, 2026 that it integrated Factorial's FEST solid-state battery cells into a Dodge Charger Daytona development vehicle and began a road-testing program to validate performance, safety, and reliability.

The companies said the milestone is the first integration of solid-state cells into a Stellantis vehicle and the first automotive integration of the technology in North America.

Stellantis Chief Engineering and Technology Officer Ned Curic said the goal is a system that delivers real benefits in a real vehicle, citing potential gains in range, charging speed, and cost.

Factorial CEO Siyu Huang said the program covers cell chemistry, pack architecture, and on-road validation on a STLA Large-based development car.

Stellantis and Factorial previously reported FEST cells at 375 Wh/kg energy density, charging from 15 percent to 90 percent in 18 minutes, and operation from minus 30 degrees Celsius to 45 degrees Celsius in lab validation.

Engineers adapted pack mechanical architecture, control systems, and safety systems to integrate solid-state cells into the existing battery pack rather than treating them as drop-in lithium-ion replacements.

The road-testing phase will tune pack performance under charging and driving conditions and verify vehicle safety before any production decision.

Stellantis framed the program as the first vehicle in a previously announced multi-stage development plan with Factorial.

Solid-state battery headlines have been a decade of soon.

Road testing in an actual Dodge Charger Daytona development car is the first sentence that should slow you down for a good reason.

Not hype.

Because a real car left the lab.

Stellantis putting Factorial cells into a Charger Daytona test mule is culturally loaded in ways press releases underplay.

This is not a compliance pod.

It is a loud American coupe body with battery chemistry people keep calling next generation.

For enthusiasts in Korean American and Vietnamese American car circles who already argue about whether the Daytona EV counts as muscle car heritage, the battery story is part of the identity fight.

Range and charge time are the specs that settle family objections.

Identity is the spec that settles group chat.

You should still not preorder anything based on a development vehicle.

Road testing means calibration, failure modes, and winter days nobody Instagrams.

Stellantis quoting 375 Wh/kg and 15-to-90 percent charging in 18 minutes comes from prior cell validation, not your commute.

Factorial's name appearing alongside Mercedes-Benz and Hyundai investors reminds you this is a supplier race, not one automaker myth.

If solid-state scales, it changes road-trip math for luxury buyers comparing Lyriq, Model S, and German SUVs.

If it stalls, you still live in today's lithium-ion reality.

Asian Canadian readers waiting on U.S. battery breakthroughs should treat this as upstream news.

It may improve the cars you buy in three to five years.

It does not change this month's lease payment.

Pair the announcement with our BMW iX3 range-test note and the GM grid stories from this week.

Together they show where EV competition is moving: verified range, faster charging, and energy ecosystems outside the car.

When a relative asks if EV tech is mature, you can say lab records are finally riding on public roads in recognizable sheet metal.

When they ask if they should wait, the honest answer is still buy for your current routes and charging access.

Waitlists for solid-state are not open.

Curiosity is free.

Upgrading too early is not.

Watch whether Stellantis publishes road-test results with the same transparency independent clubs demand in Europe.

That will tell you if this is engineering or marketing with a Charger silhouette.
