The Slate’s biggest weakness is range, and it gets worse the moment you put it to work. In good conditions, the truck is rated for up to 205 miles on a charge.
Towing is hard on every electric truck. A Rivian R1T with its largest battery is rated at up to 328 miles, but pulling near its 11,000-pound limit cuts that in half, to about 164 miles. Apply the same kind of loss to the Slate, and towing at its 2,000-pound limit could leave you with 100 miles or less.
A full bed hurts too, though less. Going by the Ford F-150 Lightning, a heavy cargo load can trim range by as much as 25 percent. If your idea of a truck day is a short run to the garden center, that’s fine. If it means towing a trailer two hours to the lake, plan your charging stops carefully.
Another limit is traction. The Slate is rear-wheel drive only. In an email shared on a fan forum, Slate said all-wheel drive is planned for a future version, but the company hasn’t confirmed it publicly, and it won’t be offered at launch. Slate says its setup is a balance between range, towing, stability and heat, since long towing runs can overheat the motor and battery parts in any EV.
