My Clarity routinely got 55-65 EV during the summer months.
Keep in mind the EV range on the dash is an estimate. Range estimate has everything has to do with ambient temps and driving habits. At 50 degrees my range was 50-55 while others report 40-45 range at 50 degrees...driving habits etc.
Not a linear relationship. Multiple factors play into it.
My advice is not to fret. Drive it for a few months then you hopefully will get a feel for how it operates and be able to correlate charging with temps with habits.
i don't think you should ever take the % from the dash as a real indication. It is known to be a rough estimate and will obviously not necessarily represent reality of driving depending on a lot of factors.
