The link works ok here. 502 indicates a server problem, so that might have been temporary.
I’ll state that we don’t really need to discuss how standardized measurements will never be able to reflect every conceivable use case in every conceivable geography, because that is simply not what these ratings are there for. They exist to make vehicles simpler to compare.
And of course manufacturers will use (and emphasize) those estimates if that makes them look better. Doesn’t make a difference if EV or ICE manufacturer.
None of my past ICE vehicles ever got close to the rated consumption. Common sense tells me I shouldn’t expect things to be different with a different propulsion system.
