Can you or JST speak to how much range you lose going 85mph versus 75mph? LA traffic is really fast at non rush hour.

I never thought to look up what our cars mpg was rated at but your question had me curious … just looked and our Audi Q7 6 cylinder is rated at 23 mpg Highway (unless I went to the wrong website) and we average 26 mpg on road trips

Since drag increases with the square of speed, you do get a noticeable efficiency and range hit at 85 v 75. Unfortunately I can’t really quantify it from personal experience because there aren’t too many places around here where you can cruise at 85.
This thread suggests maybe a 25 percent hit? https://teslamotorsclub.com/tmc/thre...80-mph.266680/ But this is why I’d rent the car and see how it does for you. |

The difference in the (old) GT3 chugging along at 70-75mph in sixth versus 85 to……120mph is like 18mpg versus the low teens. Pushing a lot more air. I’d not change my driving style hence this beta test. I’ll try to do it this week.
