The EPA published the official range figures as part of its routine updates in much the same way that European regulators update the official emissions figures used for UK car tax brackets.
The Model S 90D increases its previous official figure by 9 miles, while the dual-motor P90D has also extended its official range from 253 to 270 miles.
Tesla says these increases in range come thanks in part to the facelifted car’s more aerodynamic front end – the 2016 model features a smoother nose than the outgoing car – but are largely due to the fact that the EPA has now tested a 90D with a 90kWh battery.
Previous figures used percentage-increased estimates based on tests in a car with an 85kWh battery.
Aside from an increased range, the new Model S can also charge faster than before, thanks to its charger being upgraded from 40A to 48A.
Earlier this week, Tesla added 150 so-called Destination Chargers to its European recharging network, with 26 finding homes in the UK. The car maker also posted a picture of a Model S parked in front of a wall displaying the number 100, leading to suggestions that a new Model S 100D, with an even longer range, is on the way.
