"Cybertruck Proves Its Mettle with 254-Mile Highway Range Test"

An independent highway range test of the Tesla Cybertruck resulted in a 254-mile drive on a single charge, falling short of the EPA's estimated 320 miles. The test was conducted in cold weather at 46 F (8 C) and at a constant speed of 70 mph. Concerns have been raised about the Cybertruck's performance in colder temperatures and when towing loads, especially without the additional "range extender" battery system, which costs $16,000 and takes up space in the truck bed.
