I'd be thrilled to see that reduction for some relief. It would drop the AC bill at least. This whole winter in Florida was misserably hot. Can't imagine how bad the summer is going to be.Even here I was getting a 40% reduction in range during the winter with my 500e
our RAV4 Prime is getting 3.0-3.2 mi/kWhIt appears to calculate range by battery state of charge x recent mi/kWh figure for your driving style/speed etc.
This method is very common in the industry and seems to be the most reasonable method. A fully charged battery in the 4xe is about the same as a half gallon of gasoline. (0.43 gallons to be exact...) If you look at it that way......then your Jeep is getting over 60 miles per gallon of energy under those driving conditions. Pretty nice.
However, as electrified vehicles become more normal.....we are going to stop talking about miles/gallon equivalent (MPGe) and migrate to a mi/kWh figure instead. You are getting about 2 miles/kWh. My Focus Electric averages 4.0. My Mach-E averages about 3.5. When the BEV Wrangler becomes available for sale we might be lucky to see 3.0 mi/kWh. (this last sentence is just a guess though......)
"Preconditioning" itself drains battery.Unless you have heated seats then it isn't that big of a penalty. Depending on how cold it gets of course. Here in AZ, heated seats used in tandem with departure time pre-conditioning goes a long way to minimizing range loss during winter driving.
Does the 4xe have a PTC resistive type heater? And can it be turned off?
