Slate Drove Their Electric Pickup Through 10 Inches of Frozen Slush, Then Froze It Solid. Here's What Happened.

Slate Auto hauled its electric pickup to Keweenaw Research Center in Michigan's Upper Peninsula for a full cold weather torture test. The program included driving through slush troughs, freezing vehicles in cold chambers, running dynamics courses on ice, and then checking if everything still works the next morning. After a full freeze-and-thaw cycle, the brakes released on their own, nothing broke underneath, and the truck came out under its own power. Slate is targeting deliveries by the end of 2026, and this is the kind of behind-the-scenes engineering footage that usually stays internal.
