A 2026 Chevrolet Silverado EV Max Range Work Truck, EPA-estimated for up to 493 miles, achieved 1,059.2 miles on a single charge during a range test conducted by the GM engineering team, the company reported.

Test Setup

The challenge began as an internal discussion among engineers about the truck’s maximum potential range. A stock Silverado EV Max Range WT was driven on public roads near GM’s Milford Proving Ground and Detroit’s Belle Isle. Engineers rotated in one-hour driving shifts.

No hardware or software changes were made to the vehicle. Adjustments were limited to settings and driving habits within owner’s manual guidelines:

• Maintaining speeds between 20–25 mph where safe

• Avoiding hard braking and rapid acceleration

• Driving without passengers for most of the test

• Lowering windshield wipers to the minimal acceptable position

• Inflating tires to the highest recommended pressure

• Removing the spare tire to reduce weight

• Optimizing wheel alignment

• Adding a tonneau cover for improved aerodynamics

• Turning off climate control

• Conducting the test in summer for optimal battery temperature

Performance Insights

The most efficient speed was found to be 20–25 mph, minimizing energy use outside of propulsion. The test aimed to generate real-world, applicable data for engineering teams rather than a theoretical maximum under unrealistic conditions.

“This achievement reflects integration across battery chemistry, drive unit efficiency, software, and vehicle engineering,” said Kurt Kelty, vice president of battery, propulsion, and sustainability, in a recent news release.

Range Leadership

With an EPA-estimated 493-mile range, the 2026 Silverado EV Max Range WT currently leads electric truck range ratings. Range remains the top purchase consideration for Silverado EV buyers, according to GM research.

The record-setting vehicle was later used to power a 3D printer that produced a trophy commemorating the milestone.
