Yeah, like in mid winter on the highway? Is it possible that Jeep made a mistake and had the mode in "save the electric and generate some more" while doing the EPA 2.0 gas testing? Or, did they use a Rubicon for testing instead of a Sahara? In winter ambient temps? Fill out the forms wrong? These numbers don't add up. The 2.0 L is a known, it should have come out about 21 city, 24 highway, 22 combined. The MPGe came out exactly as predicted. A gallon of gas has about twice the kWh energy as the useable battery kWh in the 4xE, so the battery mileage should be about 24.5 miles, NOT 21 miles. My suggestion is for Jeep to consult with Tesla on how to do EPA testing. Something is wrong. I fully expect my 4xE to get 30+ miles on the battery in warm weather in the city and on the back roads, using just the 2.0L on the highways. I expect the 2.0L to get 25 mpg+ on the highway in warm weather. I know this from REAL WORLD use during hundreds of thousands of miles in a decade of all season driving of my Chevy Volts, Toyota Primes, Teslas and a Pacifica Hybrid.
It is a bit disappointing but I find that the EPA tends to be really conservative with their fuel economy numbers. It won't be until journalists get their hands on the 4xe where we'll see how accurate these numbers are. There are plenty of stories of how electric cars exceed EPA numbers.
