The LR battery charges faster when empty. But the consumption is lower on the RWD.
US and China Models use the CATL LFP in the SR
The German made Y SR (sold here in the EU) has a BYD LFP battery which is a bit better. 176kW peak, longer and higher charge curve than the CATL. Plug it in at any SOC and get 176kW, thats really nice. Same travel time on long drives as the LR model. Plus no need any more to arrive at a SuC with 0% to get full charge rate.
