Chevy Silverado EV Drives 1,059.2 Miles on a Single Charge, Surpassing World Record (theverge.com)74
"General Motors claimed a new world record for EV driving on a single charge," reports the Verge, "after a Chevy Silverado EV traveled 1,059.2 miles without recharging its battery."The potentially record-breaking run took place over seven days on public roads near GM's Milford Proving Ground and Detroit's Belle Isle "using smart driving techniques" that included limiting the speed to 20-25 mph. The truck was a 2026 Chevy Silverado EV Work Truck with an EPA-estimated range of 493 miles. But by making a number of adjustments, GM's engineers were able to far surpass the vehicle's estimated range...
First of all, the test was conducted in the summer for "optimum ambient temperature for battery efficiency," GM says. They also lowered the windshield wiper blades to reduce drag, inflated the tires to the highest acceptable pressure for lower rolling resistance, removed the spare tire to lighten the load, and optimized the wheel alignment. A tonneau cover was added to the truck bed for smoother airflow, and climate control was turned off for the duration of the test.
GM isn't seeking the Guinness World Records, the article adds, with a GM spokesperson calling it "a passion project led and executed by GM engineers." (The test "started out as casual conversation among a group of GM engineers in late 2024," GM says, but "quickly turned into a challenge: How far could the Work Truck go if we optimized absolutely everything?")
After the test, reports Motor Trend, "The dead truck was hauled back to Milford, its battery was topped up, and the energy used to power a Stratasys F370 3D printer, which spent 6.5 hours printing an ABS plastic trophy to commemorate the auspicious event."
