CWM Yes but see if you can find another source for E models getting 500Kmh at sea level, that is imo an exceptional event. Just about every ref I have seen is in the 460Kmh or so sea level area.
Even here the Swiss tests show 460-470 at sea level:

And the French tests only get 500Kmh (clapped out E I can here some saying
at around 3000m, though the other numbers compare quiet well with the L.Dv.556/3 for the E-1, -3 stuff quoted in this thread.
This all becomes a circular tail chase depending on the references you choose and or trust. The majority are in the L.Dv.556/3 type performance area.
