The 2024 Chevrolet Silverado EV with the largest battery available crushed its competition in a real-world test.
The electric pickup was charged for 15 minutes starting from a 10% state of charge.
The distance it traveled to get back to 10% was double compared to its main rival.

Going on a road trip with an electric car can be a daunting task, especially for newcomers. But as EVs become more advanced and the charging infrastructure expands, issues like range anxiety and charger anxiety are slowly but surely becoming things of the past.

Still, some EVs perform better than others when hooked up to a DC fast charger. And, as it turns out, the Chevrolet Silverado EV with the largest battery pack available is the best electric pickup out there when it comes to spending as little time as possible charging.

That’s what our friends from Out of Spec Testing found out during their 10% road trip challenge. The test is meant to simulate typical road trip conditions where an EV is driven down to a 10% state of charge, spends a little time replenishing its battery, and then gets back on the road.

In this test, the recharge time is capped at just 15 minutes. They use an Electrify America DC fast-charger rated at 350 kW speeds. The driver then gets back behind the wheel and cruises on the highway at a constant 80 miles per hour. When the battery percentage goes back to 10%, the test is over and the figures are noted for posterity. Here’s how the Silverado EV did.

With a 24-module, 800-volt battery pack that can store roughly 215 kilowatt-hours of energy, the Chevrolet Silverado EV 4WT you’ll see in the video below can charge at break-neck speeds—if it’s connected to a proper DC fast charger. In this instance, the truck reached a top charging speed of 361 kW and maintained over 300 kW during the entire 15-minute charging session.

In just a quarter of an hour, the American pickup went from 10% state of charge to 45% and a little over 84 kWh of energy was put back into the massive battery pack. That was enough for 129 miles on the road at 80 mph—an impressive result when compared to the competition. To put things into perspective, the Ford F-150 Lightning managed less than half the distance of the Silverado EV 4WT in the same test.

That said, what was less than impressive was the energy efficiency of the Silverado EV 4WT: just 1.7 miles/kWh, according to the car’s trip computer. By contrast, the Lucid Air, Porsche Taycan and Hyundai Ioniq 6–some of the most efficient EVs out there–have double the efficiency.

The 2024 Chevrolet Silverado EV 4WT is a fleet-oriented model and has a GM-estimated range of 450 miles. It cannot be purchased by individual customers (though examples are available on the used market) but the battery that powers it—known as the Max Range pack–can be fitted to the latest 2025 Silverado EV RST. It has a GM-estimated range of 460 miles.
