Yes, I’ve seen widely different consumption numbers as well on same routes/driving. Temperature has a huge impact on consumption … more then with other EV’s or so it seems. I’ve also seen un predicted regen, it seems when you set it to coast regen not always kicks in and you need to toggle it on the display so that you have that “light” regen when going of the accelerator …I have been independently recording all kinds of parameters associated with each trip I take for quite some time. Specifically, I am trying to understand in a "scientific" way whether there is a key factor responsible for such a disappointing range.
It's still early, but now that where I live we alternate between days of 5°C and others of 20°C, I can see that the impact of outside temperature is huge. Even a variation of just 4-5 degrees Celsius in the same route and driving style has a much greater effect than expected. And yet, under optimal conditions, the vehicle’s actual consumption—at average speeds equivalent to a low-level WLTP—results in high consumption levels.
These data, combined with those shared by a colleague in the thread about turtle mode and the vehicle stopping before reaching 0%, make me think that the battery’s "insulation" or its "lack of proper conditioning" could be the cause.
I insist that it is still too early, but I am already starting to see a trend in that direction in my data.
