I remember that whenever I read the forums people were discussing Ideal and Rated ranges. Now that I have the car the only place I've found that changes the range indicated shows two options: Rated and Typical. It seems the Rated range is based on ~180Wh/km from the line on the energy graph and the Typical is ~205Wh/km. Now either there is still a hidden Ideal setting that I've yet to find or in the EU firmware they've renamed them to Rated and Typical. Can someone care to comment? I've so far only charged to 90% (the max of daily charging that's indicated in the charging screen) and that nets me 431 km on Rated range. Simple math tells me that range charge should give me 480km of rated range then, which is ~300 miles, but not the NEDC 502km. Haven't checked what the full charge is with typical range, will know tomorrow morning when I take the car from charging as I've now swapped to it.
