I had some time to kill and calculated real efficiencies from this video. I have not heard much about ID4 range in cooler temps. 1st edition 2021 VW id.4 . I think it’s the RWD version., 8000 miles, 77kw battery, GOM showed 210 miles of range full charge for the 100% charge leg. Climate set to 68F and 65F. He notes he drives the speed limit.

1st leg, 53F, 68F climate, 82 miles, 61%-13%, 48% 37 kWh, mi/kWh=2.22. Real Range=171 miles
2nd Leg, 51F, 68F climate, 133 miles, 100%-25%, 75%, 58 kWh, mi/kw=2.29 Real Range=176 miles

Snowing highway route, 32F , 65F climate, car reported 1.7 mi/kwh highway, 55 MPH, Real Range =131 miles more than likely less with GOM error.

37F, 65 F climate, 110 miles, 80%-11%, 69%, 53 kW, mi/kWh=2.07, Real range=159 miles, car reporting 2.2 mi/kWh.

car showed 148 miles of range at 80% and 144 miles at 80%. After other 32F/37F cool temp charges.

So their overall performance seems lower than the Mach E at these conditions. They have GOM issues too. I am kind of happy I got 138 miles at 0F, and around 200 at 30F.

They all use the same basic chemistry, so they all suffer from the same fundamental problem with cold weather. Don't let the Teslarati fool you: their cars experience it too. Solid state has the potential to significantly improve the situation, but who knows how much farther into the future it will become practical.

Got at least another 10 years before solid state makes it into consumer territory :(
