Jeep Grand Wagoneer vs Land Rover Discovery: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Jeep Grand Wagoneer burns about $3,250 of fuel annually against $3,450 for the Land Rover Discovery. That $200 yearly gap compounds to roughly $1,000 over five years and $1,600 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 Land Rover Discovery leads in both cycles — 21 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 Land Rover Discovery with 3 (SIDI, SIDI; Mild Hybrid, 3.0). Across 16 recorded Jeep Grand Wagoneer configurations and 34 for the Land Rover Discovery, 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 Land Rover Discovery with All-Wheel Drive, 4-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 Land Rover Discovery emits 395 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.
