Fuel economy tests show that, in city driving, a conventional gasoline car's gas mileage is roughly 15% lower at 20°F than it would be at 77°F. It can drop as much as 24% for short (3- to 4-mile) trips. The effect on hybrids is typically greater. Their fuel economy can drop about 30% to 34% under these conditions. For electric vehicles (EVs), fuel economy can drop roughly 39% in mixed city and highway driving, and range can drop by 41%. About two-thirds of the extra energy consumed is used to heat the cabin. Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids. It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures. Heated seats, window defrosters, and heater fans use additional power. Warming up your vehicle before you start your trip lowers your fuel economy—idling gets 0 miles per gallon. Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds. Tire pressure decreases in colder temperatures, increasing rolling resistance. Winter grades of gasoline can have slightly less energy per gallon than summer blends. Battery performance decreases in cold weather, making it harder for your alternator to keep your battery charged. This also affects the performance of the regenerative braking system on hybrids, plug-in hybrids, and electric vehicles. In severe winter weather, your mpg can drop even further. Icy or snow-covered roads decrease your tires' grip on the road, wasting energy. Safe driving speeds on slick roads can be much lower than normal, further reducing fuel economy, especially at speeds below 30 to 40 mph. Using four-wheel drive uses more fuel. www.fueleconomy.gov |

| 1485194 | 2022-03-29 06:24:00 | It's quite noticeable actually, I had a 24kwh Nissan leaf with about 77% battery health for a year before trading it in and did a fortnightly 90 km open road round trip in it. In summer it was doable without stopping to charge quite easily (10-15% battery remaining) but in winter even without using the heater I usually had to stop on the way home for 5-10 minutes at a fast charger. All vehicles have reduced range in the cold, it's just much more noticeable with a smaller range to start with. At least we don't get really cold weather here. Here's a road test in a cold climate where the leaf got about half it's summer range, the Ioniq in the test did better but was also reduced www.youtube.com Here it's more like 10-20% reduced depending on if you use the heater or not. Heated seats and steering wheel do the trick if driving alone and don't drop the range much, no getting around the denser air though. |
