To be clear, our LR models recently had a larger capacity battery fitted (from 75 to 82kwh) which saw the range increase from 580kms to 620kms, and approximately 2 months later, they introduced the new chip which reduced it down to around 602kms. Still an increase over the former high voltage battery pack. Only our SR's have the LFP high voltage battery, not LR or P, and when introduced the SR acceleration time reduced by 0.5seconds.
The AMD equipped cars have the new sealed low voltage battery packs.
Our offical range estimates on teslas website have updated every step of the way, has the US tesla site updated with the new range estimates?
