I agree that this is likely to be a temporary offering for the LR version, pending a more thorough overhaul with the coming Highland version. Or at least I I hope so. I would expect that the Highland overhaul, which reportedly will include design changes making it cheaper to produce, will also be accompanied by a further price drop for a LR version, making much of the current price discrepancy go away.
I noticed that the new ‘LR’ version is not available on the Tesla Canada site. I wonder if that is because LFP batteries do not perform as well in the cold. Albeit there are plenty of places in the northern U.S., where it would be available, where it is also pretty frosty. Maybe Tesla has simply not had time to update the Canada site as well. Anyway, I don’t think that it is confirmed yet that this new version actually uses LFP.
