Back in February, Tesla CEO Elon Musk said the Model S estimated EPA range “is now above 390 miles or 630 km”, adding, “All S/X cars made in recent months have actually been above stated EPA range. Will be unlocked soon for free via software update.”
When asked if this was due to hardware differences, Musk replied, “Many small hardware improvements throughout the car that have been introduced gradually over past several months,” along with “software just thinks the car is less efficient than it actually is.”
Yesterday, Tesla debuted an Infotainment Upgrade for older year Model S and Model X owners. The $2,500 USD upgrade brings forth newer MCU2 hardware (versus MCU1), enabling access to YouTube, Netflix, Tesla Arcade and more.
