The Tesla Model S electric sedan may have an impressive claimed range of over 400 km, but it appears that there are customers who still have doubts as to whether their cars are able to go the distance, and the company is aiming to dispel these fears.

In a recent tweet, CEO Elon Musk said that Tesla will announce a software update, which he claims will “end range anxiety,” at a press conference on Thursday. No details as to how the update will do that have been released so far, but Musk did say it will be pushed out to the entire Model S range.

This dovetails nicely with another tweet from Musk earlier in the year, saying that the 691 hp, all-wheel drive P85D model will go even faster via a forthcoming update – shaving 0.1 seconds off its 0-100 km/h sprint time to 3.1 seconds – thanks to a tweak to the inverter’s algorithm.
