How Does Winter Affect the Mileage of an EV6

Hi everyone! I have a 2024 EV6 and since it’s my first electric vehicle, I’m curious about how winter affects its mileage. I’ve heard that the range might decrease significantly. If anyone has experience driving this car through winter, could you share your insights? Any tips would be greatly appreciated!

Last winter with temperatures around mid 30’s Fahrenheit, I was getting about 180 miles on an 80% charge. In colder weather, about 20’s and below, it dropped to 150 miles. These conditions affected all electric vehicles here in the Midwest US for a couple of weeks. You’ll manage much better if you have a home charger to help maintain charge during these colder months. When it warms up, the mileage should improve back to normal.

I had similar experiences here in North Carolina. I use a Chargepoint L2 charger at home and found myself needing to charge every 2-3 days last winter, more frequently than in warmer months where it was every 4-5 days. My daily commute is about 40 miles round trip.

I would estimate about a 30% reduction, but it really depends on the actual weather conditions and how cold it gets.

I’m just south of Canada, in the Midwest. Temperatures here can drop to -30 Fahrenheit or so. During summer I average about 2.8-3.2 miles per kWh, but in winter, it’s more like 1.8-2.2 miles per kWh, and at the very coldest, it was about 1.6 miles per kWh, which I was quite happy with. -30 F is definitely extreme.

-30 F is insanely cold!

Indeed, if it weren’t for my wife’s family, I might not stay here. I commute 100 miles round trip and the car handles it just fine even in those extreme temperatures.

Consider getting an all-wheel drive one with a heat pump if possible. And it’s best if you have a garage to store it in.

It’s too late for me, I already have rear-wheel drive and I don’t have a garage :')

In the harshest Montana winters, I get about 2.6 miles per kWh at 70mph for a total range of 190 miles at 100%. The coldest I drove in was -17 Fahrenheit, and I got about 2.4 miles per kWh at 65mph.

It varies. I mostly drive from garage to garage, from home to the office, and I lose about 10%. If you park it outside overnight, it’s probably different.

It really depends on how cold it gets. If the car is left out overnight in freezing temperatures, expect about a 30% drop. Fast charging speeds also decrease quite a bit.

I’m in Houston with very mild winters, and I haven’t noticed any significant change in the one winter I’ve had the car.

Here in Chicago, I experience about a 20% loss.

I charge to 100% daily, so just to share that context. Last winter in New Jersey, I was getting around 200-215 miles in weather between 10-30°F.

Charging to 100% regularly is not great for the battery.

It’s a leased vehicle, so I’m not concerned about the long-term battery health as I won’t have it by the time any potential issues may arise.

So does that mean it’s another reason to be cautious when buying used electric vehicles? Previous owners or leasers might not have an incentive to care for the car.

@Yan
Exactly. If I can help someone save a few thousand dollars because my car shows a bit more battery degradation than another, then that’s a win for the buyer.

That’s exactly what I was thinking :joy:
