The 2-cycle test is a simpler method and OEMs must deduct 30% of the range the vehicle achieves on the 2-cycle test.
When using the 5-cycle test, since they complete three more test cycles, manufacturers don't have to deduct the full 30%. They do have to adjust the number downward, but it isn't a straight 30%, and it varies depending on the vehicle and the results of the 5-cycle test."
This is why Mach E outperforms it's EPA rating, their rating is based off the 2 cycle test. The Taycan did outperform as well at launch. Porsche initially used 2 cycle test, they now have switched to 5 cycle(their EPA ratings have gone up). Tesla routinely misses their EPA rating by 10-15% in real world tests.

Agreed, especially considering EV's and their data/performance metrics are so new to everyone there really needs to be a single standard across the board to make everything more equivalent to each other. I think they should put City and Highway ranges on the ratings similar to a gas car even if there is less of a difference between the two. Also MPGe has to be one of the most useless and confusing metrics out there.
