Overview

• GM’s 2026 Silverado EV Work Truck traveled 1,059.2 miles without recharging over seven days at Milford Proving Ground and Belle Isle under controlled conditions.
• The team more than doubled the truck’s 493-mile EPA estimate by optimizing ambient temperature, inflating tires to maximum pressure, lowering wipers and adding a tonneau cover.
• Drivers stuck to 20–25 mph on public roads, split driving into workday shifts, complied with traffic rules and relied on cracked windows instead of air conditioning.
• GM designed the run as an internal demonstration of EV efficiency and has no plans to submit the results to Guinness World Records.
• The milestone highlights ongoing automaker competition in pushing EV ranges under controlled tests versus real-world, certified runs such as Lucid’s 749-mile record.
