Prior to 2024 the EPA tests were different. The 2025 Lucid’s were the first to be tested under EPA’s new protocol (which is more stringent and therefore more realistic).
Based on my personal (admittedly limited) experience with both a 2022 AGT and a 2025 AGT, I believe that the 2025’s CAN achieve their EPA rating in reasonably mild climates with reasonable driving practices and the 2024 and earlier cars CANNOT.
Many aspects of the 2025 AGT have been upgraded…battery chemistry and capacity, heat pump, electromagnetic motor efficiency, thermal management…these things are real and add up to an appreciably more efficient package. My own recent experience has yielded over 20% more efficiency out of the 2025 compared with the 2022. While I wouldn’t bank on that full 20% being accurate, I am 100% certain that the efficiency improvements in the 2025 AGT are meaningful and that the real world range has improved WELL NORTH of 10%…
What I do find strange is why Lucid has not marketed this. When you take the world’s most efficient EV and improve its efficiency and range significantly, why not actively and loudly market it?
