SaltyNZ:I think that says as much about the EPA test not being very realistic as anything else, which may be why everyone - including the US - is switching to WLTP. That said, the nominal WLTP range of the 2022 M3 RWD is 491km. I've gotten 375km out of it 100%-5%, and the Norwegian guy (Bjorn??) got 400km from it 100-1%. The car itself, after several cycles of letting it sleep at various percentages, now tells me full charge range is 434km (up from 431km on day 1) so even the car knows the standard test range is BS.
EPA seems to be relevant to US Interstate highway driving at higher speeds. You can drive at 70-80mph there for several hours at a stretch. In NZ you'd be lucky to sustain that for 5 minutes without dying. They have huge, flat plains most of 1500km across. We're a rumpled bed sheet after a heavy night. WLTP is relevant for countries with bumps and dips and narror roads passing through many small towns.
