I have read many times on here that the regen is suspended by the ecu for the first 400? miles to ensure the brakes bed in properly. So that would dent early use range.
With all the unprecedented attention to aerodynamics to seek every increment of range, it is interesting that Porsche did not move to retractable door handles a la Range Rover Velar/Evoque.
Certainly affects wind noise on our Evoque and must assist economy.
