A latest put up from the automaker’s official account on X, the social media web site beforehand often known as Twitter and now owned by Tesla CEO Elon Musk, lists numerous components that Tesla’s navigation system takes under consideration when estimating whether or not sufficient vary is obtainable to succeed in a given vacation spot.
The listing contains environmental components like wind pace and course, ambient temperature, and humidity and strain. Chilly climate impacts every EV mannequin in a different way, research have discovered, however the warmth pumps put in on newer Tesla fashions positively assist.
Your automotive 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 conduct, 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 of. Stickier and wider tires could make an enormous 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 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.

Be aware that this put up solely discusses vary estimates for Tesla navigation techniques. Tesla is much less easy when describing what you see once you’re within the automotive, not utilizing navigation however as a substitute simply following the vary estimate you see on the car interface.
The Mannequin 3 proprietor’s guide states that vary estimates displayed on the dashboard are primarily based on EPA-rated power consumption and should not account for “private driving patterns or exterior situations.” The guide additionally cautions that “the displayed vary on the touchscreen might lower quicker than the precise distance pushed” and advises drivers open the Tesla Vitality app to view vary estimates primarily based on latest power consumption.
A Reuters report earlier this yr alleged that Tesla outfitted autos 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 automobiles have been totally charged, and extra lifelike 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.
