General Motors has achieved a staggering milestone in EV performance: a 2026 Chevrolet Silverado EV Work Truck with the 205 kWh Max Range battery traveled 1,059.2 miles on a single charge, smashing the previous record of 749 miles held by Lucid’s Air Grand Touring. Over seven days, a team of 40 GM engineers drove this largely stock truck on public roads near Detroit, optimizing it with minor but clever tweaks—like removing the spare tire, inflating tires to max, improving alignment, adding a tonneau cover, lowering wiper blades, turning off climate control, and maintaining low speeds (20–25 mph)—to stretch its efficiency to the limit . This wasn’t an official Guinness submission, but it shows the real-world potential of GM’s Ultium EV technology when thoughtfully optimized.
