With differences between European WLTP and U.S. EPA standards and further differences between EPA 2-cycle and 5-cycle testing, range estimation for EVs is a morass of confusion for the consumer and obfuscation opportunities for the manufacturers. Personally, I view EPA ratings as next to useless.
The rubber really only meets the road in real-world testing done by journalistic organizations such as Edmunds, Out of Spec Motoring, State of Charge, etc.
And, just as Edmunds found in this report, the longest range any of these independent testers have ever realized in real-world conditions are with Lucids. In fact, even with the questions raised by this report, the possibly-faulty car Edmunds tested still ranked second out of fifty EVs they've tested, with first place held by another Lucid.
Among the large EV luxury sedans, Edmunds got 505 miles from Lucid's longest-range car (an Air Dream Range) compared to 422 miles from MB's longest-range electric (an EQS 450+) with a single motor and far less power. Both Tesla's longest-range car (a Model 3 Long Range) and its large sedan (a Model S Plaid) realized only 345 miles of range with Edmunds.
In trying to market against Tesla's hyped-up range claims derived from 5-cycle EPA testing, Lucid laid a trap for itself with uninitiated EV buyers who take EPA ratings too literally.
If you want the most range you can get when taking an EV on a long road trip in which you drive it as you would an ICE car (i. e., not bothering with attempts at hyper-miling), get a Lucid.
If you want an EV that will deliver its (much lower) EPA range on that same trip, get a Porsche Taycan. You'll have to charge a lot more often, but at least you'll meet that EPA rating.
