This is going to put more pressure on the competition. 5% of even 300 miles is a good 15% more. https://electrek.co/2019/10/24/tesla-increase-vehicle-power-range-software-update/ During a conference call with analysts after Tesla’s Q3 2019 earnings, Musk said that they have more improvements coming through software updates: I forgot to mention, we’re also expecting there’s going to be an over-the-air improvement that will improve the power of the Model S, X, and 3. That’s, by the way, coming in a few weeks. It should be in the order of 5% power improvement due to improved firmware. Tesla VP of technology Drew Baglino said that they have found ways to optimize the motor control, and it should result in about “5% improvement for all Model 3 customers and 3% for Model S and Model X” customers. Musk also said that the upcoming update will also bring improvements to the range, single-pedal driving, Supercharging speed, comfort, and feel. They didn’t specify which variants of each model will get the improvements beyond the fact Supercharging speed is going to improve for Model 3 Standard Range and Standard Range Plus.
