Chevrolet Tahoe vs Dodge Durango: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Dodge Durango burns about $2,950 of fuel annually against $3,250 for the Chevrolet Tahoe. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 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 Chevrolet Tahoe leads in both cycles — 22 mpg city and 28 mpg highway against 19 and 26 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Tahoe is recorded with 4 distinct engine configurations (SIDI, 3.0, SIDI; Municipal), the Dodge Durango with 4 (6.4, 6.2, 5.7). Across 77 recorded Chevrolet Tahoe configurations and 65 for the Dodge Durango, 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 Chevrolet Tahoe is offered with Rear-Wheel Drive, 4-Wheel Drive, the Dodge Durango with All-Wheel Drive, Rear-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 Dodge Durango emits 414 g/mile of CO2 versus 421 g/mile for the Chevrolet Tahoe. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
