What MPG Does Our Long-Term Jeep Grand Cherokee 4xe Trailhawk Get in the Real World?
One of the many reasons we buy and test vehicles over longer periods is to provide more realistic fuel economy reporting. While the EPA’s fuel economy ratings are a helpful guide for shoppers, they don’t always translate directly to real-world performance. We’ve been keeping track of the fuel economy in our long-term 2023 Jeep Grand Cherokee 4xe Trailhawk — when it hasn’t been in the shop for repairs — so read on for our results after nearly 7,500 miles of driving.
Officially, the EPA rates the 2023 Grand Cherokee 4xe at 23 mpg combined. That blanket rating for all 4xe variants, however, should be taken with a grain of salt when applied to our Trailhawk, which is heavier than other 4xe models and has knobby all-terrain tires that are less efficient than street tires. With that in mind, our calculated 21.2 mpg thus far seems reasonable, though it’s worth noting that this calculation includes miles driven on electric power when the gas engine wasn’t running, which we’ll detail below. We haven’t been taking special measures to maximize fuel efficiency, either. Want to keep it in the Sport driving mode? Go for it. Blast the air conditioning at its coldest setting? Sure. Blast the air conditioning while the heated seats and steering wheel are turned on? That’s weird, but still, sure.
We’ve used a little more than 353 gallons of gas to drive 7,491 miles, at a total cost of $1,646.13 — which works out to an average fuel price of $4.66 per gallon. That’s steep, but premium gas is recommended for the 4xe, and we’ve used it for all but one fill-up so far. We also recently recorded our longest distance between fill-ups at 448 miles, which was achieved in part because the editor who was driving the Jeep maximized electric-only driving by keeping the battery charged.
That all-electric driving experience is another reason we wanted to buy a Grand Cherokee 4xe. We’ve been getting, on average, a little more than 53 miles of all-electric driving between fill-ups, with a one-time high of 103.8 miles. It’s important to note that multiple charging sessions between fill-ups have helped produce these range numbers; with a fully charged battery, the EPA estimates the 2023 Grand Cherokee 4xe can go up to 25 miles on electric power.
We haven’t been able to track all of our charging costs for a variety of reasons; we’ve used some free public chargers, some of our editors’ Level 2 home charging setups don’t calculate session costs, and we’ve also regularly charged the Grand Cherokee 4xe on regular household outlets. Where we have been able to track charging expenses, it has cost anywhere from $1.59 to $2.50 to fully charge the Jeep’s battery pack.

While our ownership experience hasn’t been ideal thus far due to dealing with the consequences of an early off-roading adventure, we can say that the 2023 Jeep Grand Cherokee 4xe Trailhawk is about as fuel efficient as you could expect it to be — so there’s one rose, at least, among the thorns.
