Cold weather temporarily reduces the electric range of every plug-in vehicle. Based on published cold-weather studies, a Range Rover Sport PHEV rated at 51 EPA miles can expect roughly 30 to 45 miles of electric driving on a typical Connecticut winter day, depending on temperature and how much you heat the cabin.

Electric range drops in the cold, then returns as temperatures rise. Real-world data from Recurrent shows electric vehicles keep about 78% of their normal range at 32°F on average, and AAA testing found a 41% drop at 20°F with the cabin heater running. Because a Range Rover PHEV also has a gas engine, the vehicle keeps driving in hybrid mode when the battery runs low, so cold weather shortens electric miles without stranding you.
Estimated electric range by condition. Each estimate applies a published study's percentage change to Land Rover's EPA-estimated electric range. These are planning estimates, not Land Rover test results.
| Condition | Range Rover Sport PHEV (51 mi EPA) | Range Rover PHEV (50 mi EPA) | Basis for estimate |
|---|---|---|---|
| Reference: EPA estimate | 51 miles | 50 miles | Land Rover's published EPA-estimated electric range |
| Hot day, 95°F, A/C on | ≈42 miles | ≈42 miles | AAA: range fell 17% at 95°F with air conditioning |
| Freezing, 32°F, typical driving | ≈40 miles (35 to 45) | ≈39 miles (34 to 44) | Recurrent: EVs kept 78% of normal range at 32°F on average; models ranged from 69% to 88% |
| Cold, 20°F, cabin heater off | ≈45 miles | ≈44 miles | AAA: range fell 12% at 20°F without heating |
| Cold, 20°F, cabin heater on | ≈30 miles | ≈30 miles | AAA: range fell 41% at 20°F with the heater running |
The takeaway for Connecticut drivers: plan on roughly 30 to 45 electric miles on winter days, compared with about 50 in mild weather. For most local errands and many commutes, that still covers the trip on electricity, and the gas engine handles the rest.
Around New Haven, typical January days run from highs in the upper 30s to lows in the low to mid 20s °F, based on long-term NOAA records. That puts most winter mornings near the 20°F and 32°F rows of the matrix.
Cold snaps go further. On January 24, 2026, New Haven recorded a low of 9°F. On days like that, expect electric range below the 20°F estimates, especially on the first drive of the day.
A lithium-ion battery releases and accepts energy less efficiently when it is cold, so the same charge carries you fewer miles.
In AAA's testing, range fell 12% at 20°F with the heater off but 41% with it on. How you heat the cabin matters more than the temperature itself.
Land Rover recommends keeping your PHEV connected to a home charger so its thermal management system can keep the battery at a healthy temperature.
Warm the cabin while the vehicle is still plugged in, so the energy comes from the charger instead of the battery. Departure timers in the Land Rover Remote app make this routine.
Heating you directly typically uses less energy than heating all the air in the cabin, which helps protect electric range.
Land Rover advises care in cold conditions, as driving too fast can put extra stress on the battery.
The Save function holds charge for the end of a trip, such as quiet electric driving through your neighborhood.
Charging can take longer in the cold. Use DC rapid charging sparingly, as Land Rover recommends, and charge at home overnight when you can.

We started with Land Rover's EPA-estimated electric range for the Range Rover Sport PHEV (51 miles) and Range Rover PHEV (50 miles). We then applied the percentage changes reported in two independent studies:
Both studies measured fully electric vehicles. Land Rover has not published cold-weather range figures for its plug-in hybrids, so treat these numbers as planning estimates. Your vehicle's range display is the best guide on any given day.
Electric range drops temporarily in the cold. Based on published studies, a Range Rover Sport PHEV rated at 51 EPA miles can expect roughly 40 miles at 32°F and about 30 miles at 20°F with the heater on. The gas engine takes over when the battery runs low.
Studies of electric vehicles show about 22% lower range at 32°F on average, and up to 41% at 20°F with the cabin heater running. The loss is temporary and reverses in warmer weather.
Reduced range in the cold is temporary. Land Rover notes that extreme cold or heat can affect battery lifespan over time, and recommends keeping the vehicle plugged in at home so its thermal management can hold the battery at a healthy temperature.
Yes. In hybrid mode, the vehicle uses the gas engine and electric motor together, and in EV mode the gas engine starts automatically when more power is needed than the battery can supply.
It can. A cold battery accepts charge more slowly, so allow extra time and charge at home overnight when possible.
