Tesla Owners Club Italia managed to make a 1,078km (669.8 miles) trip with a single charge in their Model S P100D, which is pretty impressive, being that the official range of that car is just over 500km (315 miles). This is the first time that an electric vehicle has exceeded 1,000km on a single charge; the previous record was 901.2km.
Like many past record-holders, the Italian team had to hypermile (that is, optimize their driving behavior) to keep the P100D going for as long as possible. They drove around Salerno at a pokey 40km/h (24.9MPH) with low rolling resistance tires, the air conditioning turned off and an emphasis on smooth driving techniques (such as the use of Autopilot) that made the most of the battery. All told, the feat took 29 hours — you wouldn’t want to try this if you were in a hurry to get anywhere.
