In short: independent winter tests put a Model 3 at roughly 24% to 30% below its official range in temperatures between about 7°C and -15°C. The CAA’s Canadian test measured 30%. Below -20°C there is no standardized public test, so expect more and plan with a buffer.
An earlier version of this page showed range figures from a “test” we could not document. We have replaced them with published results from the Canadian Automobile Association (CAA), the Norwegian Automobile Federation (NAF) and Recurrent’s fleet data. Each figure below names its source.
What the published winter tests found
| Test | Conditions | Tesla result |
|---|---|---|
| CAA EV Winter Test, February 2025 | Ottawa to Mont Tremblant, -7°C to -15°C | Model 3: 410 km vs 584 km official (NRCan), about 30% less |
| NAF El Prix, January 2024 | Norway, -2°C to -10°C | Model 3 (2024 refresh): 441 km vs 629 km WLTP, 29.9% less |
| NAF El Prix, January 2025 | Norway, -3°C to 7°C | Model 3 Long Range: 330 mi vs 436 mi WLTP, about 24% less |
| Recurrent fleet data, November 2025 | 30,000+ US EVs, several winters | EVs average 78% of ideal-weather range at 0°C and 70% at -7°C; Model Y ranked 5th and Model 3 6th of 34 models |
Across all 14 vehicles in the CAA test, range fell 14% to 39% below the official figures. The Model 3 was not the best for range retention, but it charged fastest, adding 205 km in 15 minutes even though it was limited to 150 kW by an adapter at the test chargers.
Two caveats. The CAA did not say which Model 3 trim it drove, and none of these tests used the Shanghai-built LFP Model 3 sold in Canada. NAF ratings are WLTP, which is more generous than Canadian (NRCan) ratings, so NAF percentages are not directly comparable with the CAA’s.
What that means for the Premium RWD in Canada
Canada’s Model 3 Premium RWD is rated at 463 km. Applying the published losses as a rough guide, not a measurement:
- Recurrent’s 22% average loss at 0°C would leave about 361 km.
- The CAA’s 30% loss at -7°C to -15°C would leave about 324 km.
- At -20°C to -30°C, expect less than that. Cabin heating demand grows as it gets colder, and LFP cells deliver less power and accept charge more slowly until the pack warms.
For most commutes with home charging, that is still plenty. It matters more for long winter highway trips, where you will stop to charge more often than the rated range suggests.
Why EVs lose range in the cold
- Heating the cabin. A gas engine heats the cabin with waste heat; an EV has to spend battery energy on it. Teslas sold since 2021 use a heat pump, which helps, but heating still takes a real share of energy on short trips.
- Warming the battery. A cold pack holds its charge but cannot deliver or accept energy as freely, so the car spends energy warming it, and regenerative braking may be limited at first.
- Denser air and winter tires. Both add resistance, especially at highway speed.
The loss is temporary. Range returns as temperatures rise; see our battery degradation guide for what does cause long-term wear.
How to keep more winter range
- Precondition while plugged in. Set Scheduled Departure so the cabin and battery warm on grid power before you leave.
- Use seat and steering-wheel heat and a lower cabin temperature. Heating your body takes far less energy than heating the air.
- Slow down on the highway. Drag rises quickly with speed and matters more in dense cold air.
- Navigate to Superchargers in the car. The car then warms the battery on the way, which shortens cold charging sessions.
- Follow Tesla’s LFP charging advice. For LFP cars Tesla recommends keeping the charge limit at 100% and fully charging at least once a week. More on that in our LFP battery guide.
Is the Model 3 a good winter car for Canada?
If you can charge at home and your daily driving is well within about two-thirds of the rated range, yes. If you regularly drive long highway distances in deep cold or cannot charge at home, compare the Model Y (built in Berlin; the RWD was reported eligible for the federal rebate) or an AWD trim with a larger battery. Home charging costs by province are in our charging cost guide, and local winter notes are on the Ontario, Quebec, Alberta and British Columbia pages.

Frequently asked questions
How much range does a Tesla Model 3 lose in winter?
In the CAA’s February 2025 winter test between Ottawa and Mont Tremblant (-7°C to -15°C), a Model 3 drove 410 km against its 584 km official rating, about 30% less. Norway’s NAF measured a Model 3 about 30% short of its WLTP rating at -2°C to -10°C in 2024, and a Model 3 Long Range about 24% short at -3°C to 7°C in 2025.
Does the LFP Model 3 lose more range in the cold?
LFP cells are more sensitive to cold than the nickel-based cells in Long Range Teslas, mainly in charging speed and available power until the pack warms up. We have not found a published standardized test of the Canadian LFP Model 3 in deep cold, so treat the roughly 30% loss in the CAA test as a starting point, not a ceiling.
How far will a Model 3 Premium RWD go at -20°C or -30°C?
Nobody has published a standardized test at those temperatures that we can cite. For reference, the same 30% loss the CAA measured at -7°C to -15°C would take the 463 km rating to about 324 km. Colder weather, short trips and highway speed push it lower, so plan with a buffer.
Does cold weather damage a Tesla battery permanently?
No. Winter range loss comes back when temperatures rise. Geotab’s 2026 study of more than 22,700 EVs found hot climates, not cold ones, added to long-term battery wear.
How do I get more winter range from a Tesla?
Keep the car plugged in and use Scheduled Departure so the cabin and battery warm on grid power, use seat and steering-wheel heat, slow down on the highway, and use the car’s navigation to a Supercharger so it preconditions the battery before charging.
