Jeep Grand Wagoneer vs Toyota 4Runner: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota 4Runner burns about $2,650 of fuel annually against $3,250 for the Jeep Grand Wagoneer. That $600 yearly gap compounds to roughly $3,000 over five years and $4,800 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 Toyota 4Runner leads in both cycles — 23 mpg city and 26 mpg highway against 17 and 24 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Jeep Grand Wagoneer is recorded with 2 distinct engine configurations (SIDI, 6.4), the Toyota 4Runner with 4 (SIDI & PFI; Hybrid, SIDI & PFI, SIDI & PFI; with Stop-Start). Across 16 recorded Jeep Grand Wagoneer configurations and 42 for the Toyota 4Runner, 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 Wagoneer is offered with Rear-Wheel Drive, All-Wheel Drive, the Toyota 4Runner with 4-Wheel Drive, Part-time 4-Wheel Drive, Rear-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 Standard 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 Toyota 4Runner emits 380 g/mile of CO2 versus 456 g/mile for the Jeep Grand Wagoneer. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
