Musk tweeted that the “entire Model S fleet” would benefit from the update, which seems likely to boost the battery range of the pioneering pure-electric luxury sports sedan.
Tesla currently claims a range of 335 kilometres for the base 60kWh battery pack in the Model S 60 and between 407km and 435km for the larger 85kWh pack that’s available in the 85, 85D and P85D variants.
Musk’s midnight tweet came a little over seven weeks after a similar promise delivered over social media that a software update would see the P85D’s 0-100km/h acceleration “improve by ~0.1 second”, while “P85 acceleration will also improve, but not quite as much”.
Tesla’s over-the-air updates work much like a software upgrade for a smartphone, allowing owners to download them over the cellular network without needing to head into a dealership.
Australian Tesla Model S vehicles received their first over-the-air update last month, with the vehicles gaining a radar-based cruise control system dubbed Traffic-Aware Cruise Control, a collision avoidance warning system, auto high-beam headlights, and a ‘smart preconditioning’ function to set the car up to your preferences based on your daily routine, among others.
