After 32 hours of driving, Sean Mitchell and Erik Strait managed a ridiculously impressive 606.2 miles on a single charge in a silver Tesla Model 3. It beat a previous record of 560 miles from a larger Tesla Model S P100D, but it fell slightly short of an alleged 670-mile run from last August.

Mitchell and Strait started at a Supercharger near Denver International Airport, and didn't get much farther than that -- the nearby drive route was basically a mile-long loop that the pair drove between 20 and 30 mph. They only occasionally stopped to use the bathroom, and received food from friends using a net held out the window.
