The official EPA ratings just came out for the Unlimited 4xe.
21 Miles all electric, then 20mpg in hybrid mode (equal in city and highway). 370 miles of total range.
Honestly that is a bit lower than I was expecting. I didn't think that it would be a Prius given it's weight and profile, but I thought it might end up at 25 mpg given that the 4 cylinder is rated at 22 overall and has higher both city (21) and highway (24) mpg. Now the 4xe might come closer to its stated miles, esp in city driving, but still, not quite what I'd hoped.
I do have a commute that could be done on all electric mode, so the 4xe still might be the most efficient of the Jeep options if I were to use it as my primary car, but in a family with two cars, it sounds like it would make more sense to use the second more efficient car as the commuter.
I was always more interested in the Gladiator 4xe in any case, but I suspect that will be lower given its slightly lower gas mileage than Wrangler Unlimited.
