The US ratings show the 85 as EPA rated, but no such tagline for the 85D, the Canadian site on the other hand quotes NEDC for rating on the 85, and nothing for the 85D... what difference that makes... I don't know.
Either way, something's amiss, because what increases the range in one country shouldn't decrease it in the other. This is also quite important, because I see many people, myself included, who will take whichever of the 2 versions gets the most range, so it would be really good to know which is which!
