Jeep Grand Cherokee vs Kia Sorento: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia Sorento burns about $1,650 of fuel annually against $2,650 for the Jeep Grand Cherokee. That $1,000 yearly gap compounds to roughly $5,000 over five years and $8,000 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the Kia Sorento leads in both cycles — 39 mpg city and 36 mpg highway against 23 and 30 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Jeep Grand Cherokee is recorded with 4 distinct engine configurations (SIDI, 3.6, SIDI; PHEV), the Kia Sorento with 4 (SIDI; Hybrid, SIDI; PHEV, SIDI & PFI). Across 87 recorded Jeep Grand Cherokee configurations and 74 for the Kia Sorento, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Jeep Grand Cherokee is offered with Rear-Wheel Drive, All-Wheel Drive, 4-Wheel Drive, the Kia Sorento with Front-Wheel Drive, All-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Kia Sorento emits 105 g/mile of CO2 versus 177 g/mile for the Jeep Grand Cherokee. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
