Overview

• General Motors engineers drove a production 2026 Chevrolet Silverado EV Work Truck 1,059.2 miles on a single charge, surpassing its 493-mile EPA rating.
• The team made only owner-replicable adjustments—such as maximizing tire pressure, adding a tonneau cover, lowering wipers, removing the spare tire, optimizing wheel alignment, and turning off climate control—to reduce drag and rolling resistance.
• Drivers maintained average speeds of 20–25 mph and employed gentle acceleration and braking over seven days on public roads around GM’s Milford Proving Ground and Detroit’s Belle Isle.
• GM has no plans to submit the run for Guinness World Records verification and the data has not been independently validated.
• The endurance experiment underscores the difference between controlled hypermiling tests and everyday driving conditions, highlighting both the Silverado EV’s large 205-kWh battery potential and realistic range expectations.
