I have had my SR+ (UK) for just under a week. So far, range is a LONG way short of what I expected. I've tried some calcs to try to work out what is going on. On an 80% charge, I get 185 miles range, which is 20 miles short of 80% of the 254 WLTP advertised. I've been told the in-car display uses EPA range of 240 miles instead of WLTP, but 80% of that is still 192 miles. I've read that it is a 50kWh battery, so 208 Wh/m gets you to 240 miles range. I've also seen reference to 217 being used for EPA calc, which does get me to the 185 range am seeing for 80% charge (but only 230 full charge range), so I'm going to assume this is what is being used by the car as 'stardard efficiency'.
Today, I started with 185 miles (80% charge). I've driven 62 miles at 279Wh/m which is 17kWh used. If the battery is 50kWh, that means there is 23kwH capacity left from the 40kWh I would have started with at 80% charge. Divide that by the 217, and I should see a range of 106 miles left. I actually see just 85miles left. Everything I have read says the miles remaining on the battery gauge does NOT take into account how you are actually driving. If it did, the 85 miles would make a bit more sense, as this would seem to assume 270 W/m, which is sort of in line with what I did for the 62 miles.
I've see articles saying normal driving is in the 250-300 w/m range, suggesting todays 60 mile trip would suggested is not crazy in-efficiency. The weather is very mild here too currently. so based on todays trip information, my actual likely range for the car is 180 miles, a good 30% less than the advertised 256 miles!!!!
I'm sure I am not the only new owner trying to get there head around this and finding range is way less than expected. Am I alone in this or are others seeing the same issues? Input appreciated!!!
