We did our first road trip this weekend with the R1S. (First BEV road trip of any kind!) Drove from Oklahoma City to Fort Worth on Friday night, and back this evening. That’s a 200mi trek which is 3hrs straight through, or 3.5-4 if you have young kids like us. The trip is almost completely level, according to my buddy with a tesla.
On 21s with the aero covers in conserve mode, I was disappointed in our range. On the way there it wasn’t terrible. I did about 2.2mi/kwh and the trip took us 70% of our large pack battery SOC. So on the way back we left with 90% SOC, and we had a direct headwind the whole time, and added 44kwh at a dcfc halfway because we weren’t going to make it home. According to weather.com the wind was 15mph, but at the charge-up the rain was coming down sideways and I bet it was closer to 25. Struggled to get more than 1.8mi/kWh and usually lower than 1.5 unless I was drafting behind a semi. It was a little chilly but never less than 40degF even towards the end tonight, and my tires were a little lower than the recommended 48 because of the cold, but still over 42psi.
So is this huge drop in range expected from a headwind alone?
Also, in the gauge view I could see the front motors nearing overheating in conserve mode, such that the bar turned orange and the diagram of the vehicle turned orange near the front motors, too. Is that expected as well? I never got any warnings on the dash but when we knew we had no range worries I switched over to all-purpose mode.
