Towhee said:300-400 wh/km works out very roughly to 480-500 wh/mile. This is what I experience on interstates and US hwys at 60 mph with my model Y pulling a 320 bd. If I charge to 300 miles indicated and plan to not discharge to zero this gives me about 100-120 miles of range. I camp at state parks here in Washington so range has not been a problem. Moseying along back roads at 35-40 mph is more like a 30 percent hit. Most parks here have both 50 and 35 camp outlets on the same pedestal which easily charges the Tesla overnight and providing power to the trailer. I also use a 35 camp splitter for those campsites that don't have 50 amp service.
It's good to understand that aerodynamic drag is a function of velocity squared. So the drag increase from going 50 to 60 is 44%!d_v said:What is your typical wh/mi with the 400? What speed do you typically go for best efficiency (within reason). I realize slower is always better, but is 50 a significant difference from 60? What tires are you running on the 400? Have you considered low resistance ones?
Thank you,
