What's your EV's real range — in winter cold and summer heat?
EPA range is measured at ~75°F. A 20°F hard freeze cuts it 22–33% depending on whether your trim has a heat pump; a 100°F heat wave typically costs 17–18%. Pick your model + temperature for an honest number anywhere from −20°F to 110°F.

The full temperature curve: % of EPA range you keep
One continuous model from arctic cold to extreme heat. Below 70°F the curve splits by heat-pump status (that's where a heat pump earns its keep); above 70°F a single fleet-average curve applies to every model, because Recurrent's data shows heat-pump status barely changes hot-weather range. Multiply the percentage by your EV's EPA range for the expected miles.
| Temperature | With heat pump | No heat pump | Status unknown |
|---|---|---|---|
| Extreme heat (105F+) | 80% — all models fleet est. | ||
| Heat wave (100F) | 82% — all models fleet est. | ||
| Hot + AC (95F) | 85% — all models fleet est. | ||
| Hot (90F) | 95% — all models fleet est. | ||
| Warm (80F) | 98% — all models fleet est. | ||
| Optimal (70F) | 100% | 100% | 100% |
| Cool (50F) | 91% | 86.8% | 89% |
| Freezing (32F) | 82.9% | 74.9% | 79.1% |
| Hard freeze (20F) | 77.5% | 67% | 72.5% |
| Deep cold (0F) | 68.5% | 53.8% | 61.5% |
| Arctic (-10F) | 64% | 47.2% | 56% |
| Extreme cold (-20F) | 59.5% | 40.6% | 50.5% |
Cold-side percentages come from the linear winter model calibrated to Recurrent's 2025-26 winter study; heat-side percentages interpolate Recurrent's 2025 summer study and AAA's 95°F test. 70°F is the 100%-of-EPA baseline. All values are estimates — see the methodology.
Why EVs lose range in cold weather
Cold weather hurts EV range in three compounding ways. First, cabin heating: unlike a gas car (which has free waste heat from the engine), an EV has to make heat from battery energy. A resistive heater pulls 3–5 kW continuously — that alone is the energy of driving 10–15 mph. Second, cold lithium chemistry is less efficient: internal resistance rises, available capacity drops, and the battery has to spend energy warming itself before fast-charging. Third, denser cold air increases rolling and aerodynamic drag, and tire pressure drops about 1 PSI per 10°F.
The heat-pump advantage
A heat pump uses a refrigerant cycle to move heat from outside (or from the motor + battery) into the cabin instead of generating it. At typical winter temperatures it uses roughly 1/3 the energy of a resistive heater. That's why Tesla, Hyundai, Kia, BMW, and most premium EVs have made heat pumps standard. A few trims still ship with resistive heat — most notably the US-market VW ID.4 — and you'll see roughly an 8-point range gap in winter (Recurrent's 2025-26 data puts heat-pump EVs at ~83% of range retained in freezing weather vs ~75% for resistive-heat EVs) that's permanent and unfixable. The full heat-pump table below lists every model's status.
How accurate is this calculator?
The winter model is calibrated to Recurrent's 2025-26 winter study — real-world data from 30,000+ US vehicles — cross-checked against AAA's winter-range testing. It's a linear approximation: real range varies ±5% based on how aggressively you heat the cabin, your highway/city mix, whether you precondition while plugged in, and your driving style, and it intentionally undershoots in extreme cold (below about -10°F), where battery effects compound. For reference, Norway's independent El Prix 2026 winter test (run by NAF and Motor magazine) put 24 EVs through -32°C conditions and saw an average 38% drop versus their rated WLTP range — deeper than typical US winters because of the severity. We deliberately don't model snow tires, cargo load, or roof racks — those compound on top of the temperature loss but vary too much between drivers to estimate.

Figures are estimates at 20°F from each model's maximum EPA range; a dash in the heat-pump column means it isn't separately confirmed, so a fleet-average loss is applied. Real winter range varies ±5% with how you heat the cabin, your speed mix, and preconditioning.
Why EVs lose range in hot weather (and why it's milder than winter)
Heat costs range for one main reason: air conditioning — both for you and for the battery. Below about 90°F the hit is small (2–5% in Recurrent's 2025 summer study of ~30,000 EVs) because the AC only has to bridge a modest gap between outside air and a 70-ish°F cabin. Above 90°F the compressor works continuously and the car starts actively cooling its battery pack, so the curve steepens fast: about 5% loss at 90°F, 15–17% by 95°F (AAA's controlled 95°F test with AC running measured ~17%), 17–18% at 100°F, and roughly 20% beyond. That steep 90→95°F step is real — it's the thermal-management load kicking in, not a rounding artifact.
Why is summer still so much gentler than winter? The temperature gap the climate system fights is smaller (20–30°F in summer vs up to 50°F+ in winter), and cooling moves heat while resistive heating has to make it. There's even a bonus zone: Geotab's 5.2-million-trip dataset shows EVs holding 100% or more of rated range from about 50°F to 88°F — many EVs beat their EPA number in mild weather. We conservatively cap our model at 100% of EPA, so mild-weather figures here are slightly pessimistic by design.
One honest caveat, and it matters: hot-weather loss varies enormously by model. The heat-side curve is FLEET-LEVEL and applies to ALL models identically. Per-model heat behavior varies enormously in reality (Recurrent's own data at 100F ranges from ~2% loss for the best performers to ~18% for the worst). Applying this single curve to a specific model is an estimate of the typical AC-running case, NOT a per-vehicle guarantee. That's why every hot-weather figure on this page carries an estimate label, and why the heat side of the calculator doesn't split by heat pump — Recurrent found heat-pump status barely moves the summer number (93% vs 97% retention at 90°F; 85% vs 87% at 100°F).
Scope note: this page is about range on a hot day, which is temporary. Sustained extreme heat and its effect on long-term battery health is a different topic — that's permanent degradation, covered in our used EV battery health guide.
Summer range for 67 popular EVs at 100°F estimates
Estimated range in a 100°F heat wave for the same 67 models, applying the fleet-average heat curve (82% of EPA range retained at 100°F) to each model's max EPA range. Unlike the winter table, these are not differentiated per model — real-world hot-weather behavior spans ~2% to ~18% loss at 100°F, so read these as the typical AC-running case.

Which EVs have a heat pump?
Heat-pump status for the 50 EV model families we track, from manufacturer spec pages (cited per row; last verified June 14, 2026). A heat pump is the single biggest winter-range differentiator — worth roughly 8 points of retention in freezing weather — but it makes almost no difference in summer heat, where AC load dominates. If a model is "optional," confirm the specific car's build sheet before buying used.

Methodology, sources & caveats
Cold side (below 70°F): a linear loss model — min(60%, (70 − temp) × coefficient) — with the coefficient set by heat-pump status: 0.0045 (heat pump standard), 0.0066 (no heat pump), 0.0055 (unknown/optional). Calibrated so retention reproduces Recurrent's published winter figures: ~83% at freezing with a heat pump, ~75% without, fleet ~70% at 20°F. This is the same winter model this site has published since the tool launched — unchanged.
Heat side (above 70°F): piecewise-linear interpolation between fleet anchors — 98% of EPA at 80°F, 95% at 90°F, 85% at 95°F, 82% at 100°F, 80% at 105°F and hotter (held flat; we don't extrapolate to older thin-data 20–30% claims). One curve for all models. At exactly 70°F both sides equal 100%, so the curve is continuous.
Estimates, not guarantees: Every output is an ESTIMATE. Real-world range swings +/-5% (or more) with cabin-climate usage, highway vs city mix, preconditioning, driving style, speed, tire pressure, and payload. These are modeled figures, not measured per-vehicle results.
Deep-cold honesty note: the linear cold model is calibrated to Recurrent's fleet data and intentionally doesn't fit the non-linear compounding below about −10°F. Geotab's blended fleet dataset reads deeper still in deep cold (about 54% of rated range at 5°F, vs this model's ~57–71% at 5°F depending on heat pump) — so treat sub-zero outputs as the optimistic end of the plausible band. On the mild end, Geotab finds EVs actually exceed rated range between 50°F and 88°F (up to ~115% of rated at 70°F); we cap retention at 100% of EPA and start trimming immediately below 70°F, which keeps mild-weather figures deliberately conservative.
Check the math: two worked examples
- Tesla Model Y (357 mi EPA, heat pump standard): at 20°F → 277 mi (−22%); at 95°F → 303 mi (−15%, fleet estimate).
- Volkswagen ID.4 (291 mi EPA, no US heat pump (resistive)): at 20°F → 195 mi (−33%); at 100°F → 239 mi (−18%, fleet estimate).

EV range & temperature FAQ
How much range do EVs lose in winter?
Recurrent's 2025-26 winter study (30,000+ US vehicles) found EVs retain about 78-80% of range at freezing (32°F) and around 70% at 20°F. Heat-pump trims hold up better — ~83% retained in freezing conditions vs ~75% for resistive-heat trims. The best performer was the Tesla Model X (89% from 32°F to 0°F); the worst was the VW ID.4 (63%), which has no US heat pump.
How much range do EVs lose in hot weather?
Far less than in winter. Recurrent's 2025 summer study (~30,000 US EVs) found losses of just 2-5% below 90°F, about 5% at 90°F, 17-18% at 100°F, and roughly 20% above 100°F. AAA's controlled test at 95°F with the AC running measured about a 17% loss. Individual models vary widely — at 100°F Recurrent's data spans ~2% loss (Audi e-tron, BMW i4, Rivian R1S) to ~18% (Chevy Blazer EV) — so treat any single hot-weather number as a fleet-typical estimate.
Do EVs lose range in the summer?
Yes, but modestly until real heat arrives. Up to about 90°F the penalty is a mild 2-5%; it steepens once the AC compressor and active battery cooling start working hard, reaching 17-18% around 100°F and about 20% beyond. There's an upside too: in mild warmth, Geotab's fleet data shows EVs holding 100% or more of rated range from roughly 50°F to 88°F.
Does running the AC reduce EV range?
Yes — air conditioning is the main driver of hot-weather range loss. AAA measured about a 17% range loss at 95°F with the AC running versus roughly 8.5% with it off, and Recurrent's fleet data puts the typical all-in loss at about 5% at 90°F. Cooling is still far cheaper than heating: an AC compressor moves heat efficiently, while winter resistive heating has to generate it. Pre-cool the cabin while plugged in to shift that energy onto the grid instead of the battery.
What temperature is best for EV range?
Around 70°F. Geotab's analysis of 5.2 million trips found EVs at peak efficiency near 70°F and holding 100% or more of rated range from about 50°F to 88°F — in mild weather many EVs actually beat their EPA number. Our calculator deliberately caps retention at 100% of EPA to stay conservative.
Is heat or cold worse for EV range?
Cold, clearly. At a 20°F hard freeze a typical EV gives up roughly 22-33% of its range depending on heat-pump status, while even a 100°F heat wave typically costs 17-18%. The asymmetry is starker in the middle: freezing (32°F) costs about 17-25%, but 90°F costs only about 5%.
Why does my EV lose more range in winter than summer?
Two reasons. First, the temperature gap the climate system has to bridge is bigger in winter — heating a cabin to 70°F on a 20°F day means fighting a 50-degree difference, while summer AC usually spans 20-30 degrees. Second, making heat is more expensive than moving it: a resistive heater pulls 3-5 kW continuously, while an AC compressor (or heat pump) transfers heat far more efficiently. Cold also thickens the battery's chemistry, reducing efficiency and regenerative braking — effects heat mostly doesn't have on day-to-day range.
Does a heat pump really make a difference?
Yes. A resistive cabin heater pulls 3–5 kW continuously like a giant hair-dryer. A heat pump moves heat into the cabin instead of generating it, using roughly 1/3 the energy. The range delta is biggest in the 20–40°F band; below 0°F heat pumps are less efficient and the gap narrows.
Why isn't my exact temperature getting the EPA range?
The EPA combined cycle is run at ~75°F. Anything below that — even mild 60°F days — costs a few percent. The losses come from cabin heating, less efficient battery chemistry at low temperatures, denser cold air (higher rolling/aero resistance), and tire pressure dropping.
What can I do to get more winter range?
Precondition the cabin while plugged in (uses grid energy not battery). Use seat and steering-wheel heat instead of cabin heat — they target you not the air. Park in a garage when possible. Keep tires at the recommended winter pressure. Avoid charging to 100% in extreme cold; the battery accepts charge slower and the regen window is reduced.
