The maximum range claimed for the Tesla Semi is 500 miles.
Tesla unveiled the Semi in November 2017 with two planned battery-range versions: a shorter-range model rated at 300 miles and a long-range model advertised at 500 miles. The 500-mile figure became the headline specification because it positioned the electric truck as a potential long-haul alternative to diesel semis.
Tesla began producing the Semi in 2022, with PepsiCo receiving early customer vehicles. In November 2022, Tesla reported that a Semi had completed a 500-mile drive while carrying a gross vehicle weight of 81,000 pounds. That result supported the original claim, although real-world range varies with payload, speed, temperature, terrain, and weather.
A common mix-up is confusing the original 300-mile and 500-mile versions. The question asks for the maximum claimed range, not the shorter model's rating or the distance a loaded truck may achieve on a particular route.
