The most fuel-efficient Jeep Cherokee can get up to 31 miles per gallon on the highway--so agrees the EPA. Most versions earn everyday gas mileage in the low-20-mpg range, with the most rugged editions dipping below 20 miles per gallon on the city cycle.
In spite of its standard nine-speed automatic transmission, the Cherokee doesn't fare so well against some other mid-size and compact crossovers--vehicles like the Hyundai Santa Fe Sport, Honda CR-V, Ford Escape and Edge, and Chevy Equinox. None of those crossovers has its adventurous talent, though. The beefed-up body structure and heavier running gear its Trail Rating demands accounts for at least some of that fuel-economy penalty.
Adding the basic all-wheel-drive system to the four-cylinder Cherokee drops gas mileage to 21/28 mpg, or 24 mpg combined; going with the more advanced Active Drive II setup lowers highway economy by one more mile per gallon, to 27 mpg, and combined numbers to 23 mpg.
On six-cylinder Cherokees, fuel economy starts at 19/28 mpg or 22 mpg combined for front-drive models; Active Drive I all-wheel drive lowers highway economy to 27 mpg; and Active Drive II drops it one more notch, to 26 mpg highway.
