Looking back I could not find a listing of W/KM usages for Canada. I see various posts where owners are getting 175 W/km but I have never been able to achieve this. I normally drive on the 401 at around 110-112 km per hour and in 80km zones roughly 10% over the limit. I'm from southern Ontario and my lifetime average to date( 4 months) is 227 w/km over 12000 KM. Even last weekend I went to Orillia using HWY 12 and could only get 220 w/km. I kept it at a reasonable speed and the battery pack was warm before we left. I have the 21" turbines and a S85. I would like to see other peoples averages if possible. Please post your car and tire sizes too if possible. I track my monthly averages in a notebook and will keep posting over the summer to see if this improves.
