Tesla Model S manages 647 km range

Tesla has announced that it has become the first manufacturer to break the 400-mile (643.74 km) range for production electric vehicles. The Tesla Model S Long Range Plus has managed to achieve this feat.

The announcement comes after the CEO displayed displeasure over a previous 391-mile (629 km) rating given by the US Environmental Protection Agency (EPA). According to Musk, someone at the testing agency left the keys inside the car and the door open overnight resulting in a 2% depletion of the car's range.

Some of the changes done over the years to the Model S include lowering the weight by in-house seat manufacturing and use of lighter weight materials in the battery pack and drive units, addition of Tempest aero wheels and tyres, improved drive efficiency by replacing a mechanical oil pump with electric pump and improved regenerative braking.

Compared to the 2019 version of the same car, there has been an improvement of nearly 20% in claimed range. All Model S Long Range Plus cars produced from January 2020 have a 402-mile (646.96 km) range.
