Tesla Model S is now the first electric car with an EPA-certified range of more than 400-miles

  • Tesla’s ‘Long Range Plus’ Model S has an official range of 402 miles
  • The unprecedented designation has been made by the EPA 
  • Reductions in weight and other improvements have increased range 

Tesla has become the first electric car company to offer 400 miles of range on one battery charge.

The company announced that its Model S sedan – at least the units labeled ‘Long Range Plus’ – have been given an unprecedented range of 402 miles by the EPA.

‘Starting today, all North American Model S Long Range Plus vehicles have an official EPA-rated range of 402 miles,’ said the company in a press release.

According to them, the designation marks an almost 20 percent increase in range when compared to a 2019 Model S 100D using the same battery pack design.  

Tesla, which issued a statement on the Model S designation, says several changes to the cars’ design have aided the unprecedented range.

Among the improvements are a reduction in mass through the use of different materials for making the cars’ seats, drive units, and battery packs.

Likewise, new lightweight and aerodynamic wheels have also helped increase range by as much as 2 percent according to the company.

Improvements in the Model S regenerative breaking, which uses the cars’ kinetic energy to bolster battery power, have also helped to increase range, Tesla says.

‘To bring the car to a stop smoothly, regenerative braking now works at a lower speed and deceleration rate, sending more energy back to the battery pack while simultaneously enabling a driving experience like no other car,’ it said.

Notably, the increase in range has little to do with improvements in the vehicles’ batteries.

On that front, Tesla’s battery supplier, Contemporary Amperex Technology Limited, says it will begin shipping shipping batteries that have a lifespan of 1.24 million miles and can last for 16 years.
