No idea what is actually going on, but the first thought that comes to my mind is that in the US you're allowed and expected to blatantly lie in marketing while in the EU you may have to keep it somewhat realistic...
No. I'm talking about the EPA (USA) rating of the e-Tron vs other cars. EPA ratings for EVs are generally pretty accurate vs real world range, although in the real world a lot depends on driving style and weather etc.
