I switched from Tesla to Lucid partly for range, since regularly drive 520 and 240 miles one way. My 310 rated Tesla would not get me the 240 miles without slowing down, but my Tesla efficiency from 2014 to 2024 ranged from 65-70% to 90%, usually 80-85%. Headwinds (and speed) were biggest factor. And cold, but usually not a factor in Texas. Nothing seems to make a difference in the Lucid, not settings, not tire inflation, not cooling or heating with the seats only, not even headwinds. 65% is about the best I get.. I figure I get about 35 miles for every 10% of charge, so my effective range is about 350 miles from my 510 rated battery. I guess, heavy battery, less range, but it’s worth it to me. I used to arrive, at destinations and charging stations, with less than 10 miles, in the Tesla. And, the Lucid is way nicer.
