It’s really pretty simple: I often get 37-43 miles of range out of my Sorento PHEV on a full charge. The only times I do not exceed the EPA range by 20-30%+ is in winter (when I have snow tires with higher rolling resistance on and the temps reduce battery efficiency), or when I have obstructive cargo on the roof (the cargo box) + a full load of people/stuff on board. All I have to do to handily exceed the EPA rated range is drive it gently and favor use of the battery for slower speeds (i.e. 50 mph or less typically). If I happen to be using the battery up for highway speeds only, I will typically only beat the EPA range by a few miles though, and so I rarely do that (it is very easy to keep it in EV mode most of the time on the freeways around Seattle though because our traffic is terrible, so driving 50 mph or less is kind of the norm). During each drive, I know when I have exceeded the 32 mile EPA range by looking at the fuel economy figures on the dash. If it reads “999” MPG after I drive 43 miles for example, that means I drove those 43 miles on electricity alone. If I switch between gas and electric, I just remember how many miles I had driven when I switched/switched back (that is admittedly tedious on a long drive, but I make a game out of it). I document all of this in a spreadsheet I religiously update. 3.2 was simply the average of all my monthly reported figures at the time (it is actually 3.16 right now, after the most recent months’ of data, which includes a few thousand miles of driving on snow tires in cold temps with heavy loads). The Sorento pHEV has 11.8 kWh of usable battery capacity (the rest is held in reserve for hybrid mode operation). With an average of 3.16 miles per kWh to date, that means I get a little over 37 miles of range per charge, cumulatively. Would you like me to do more reporting on specifics of the drives and conditions and my efficiency results? Any specific scenarios or details you would like me to measure?
