Tesla has been imprecise on how its automobiles estimate driving vary, however a current social media submit offers a little bit of readability.
A current submit from the automaker’s official account on X, the social media website owned by Tesla CEO Elon Musk that was beforehand often known as Twitter, lists various components that Tesla’s navigation system takes under consideration when estimating whether or not sufficient vary is accessible to succeed in a given vacation spot.
The record contains environmental components like wind pace and route, ambient temperature, and humidity and strain. Chilly climate impacts every EV mannequin in another way, research have discovered, however the warmth pumps put in on newer Tesla fashions positively assist.
Your automobile does the mathematics for you.
When calculating a route & battery % on arrival, Tesla navigation takes under consideration:
– Wind pace & direction- Elevation/grade- Site visitors speed- Avg acceleration/deceleration- Ambient temperature- Humidity & pressure- Photo voltaic load & cloud… https://t.co/nTDJczTthu pic.twitter.com/gbt6PCFIH7

The navigation system additionally components in driving habits, measuring pace and common acceleration and deceleration. And it takes under consideration issues like local weather management use, and the battery pack’s preliminary temperature and cost use.
Aerodynamic components—like whether or not a motorbike rack is hooked up—and estimated rolling resistance are additionally thought-about. Stickier and wider tires could make a giant distinction on vary, due to elevated rolling resistance and aerodynamic drag.
Tesla’s native navigation and journey planning have made journey planning far simpler. However now with the addition of EV journey planning by means of Apple Maps, as an illustration, drivers now have extra choices. Simply do not be so certain that these can faucet into all of Tesla’s components listed above.

Observe that this submit solely discusses vary estimates for Tesla navigation techniques. Tesla is much less easy when describing what you see if you’re within the automobile, not utilizing navigation however as an alternative simply following the vary estimate you see on the automobile interface.
The Mannequin 3 proprietor’s handbook states that vary estimates displayed on the dashboard are based mostly on EPA-rated power consumption and will not account for “private driving patterns or exterior circumstances.” The handbook additionally cautions that “the displayed vary on the touchscreen could lower quicker than the precise distance pushed” and advises drivers open the Tesla Power app to view vary estimates based mostly on current power consumption.
A Reuters report earlier this yr alleged that Tesla geared up automobiles with deceptive vary shows after which suppressed proprietor complaints about not meet vary estimates. The report alleged that Tesla programmed shows to indicate extra optimistic estimates when vehicles have been totally charged, and extra sensible estimates at decrease states of cost. It then allegedly created a particular crew to cancel buyer appointments at service facilities in the event that they have been associated to vary complaints.
