Hello all. I recently purchased a 2014 Tesla Model S 60. When I set the range display to 'ideal' rather than 'rated', at 50% charge, it shows I have a range of around 163km, suggesting a full range of 326km. On Tesla's website, the S 60 is supposed to have 338km of range. Does that mean my car has lost 12km (3.5%) of range in the last 2 years? Or was the 'ideal range' always around 326km? Is there a way to check what the condition of the battery is as a percentage compared to a NEW battery? Or in KWH? For example, if it started with 60KWH, is there a way to check if it now has 58KWH?
