Chevrolet Trailblazer vs Dodge Durango: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Trailblazer burns about $2,000 of fuel annually against $2,950 for the Dodge Durango. That $950 yearly gap compounds to roughly $4,750 over five years and $7,600 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 Chevrolet Trailblazer leads in both cycles — 30 mpg city and 33 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 Trailblazer is recorded with 2 distinct engine configurations (SIDI, SIDI; FFV), the Dodge Durango with 4 (6.4, 6.2, 5.7). Across 17 recorded Chevrolet Trailblazer 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 Trailblazer is offered with All-Wheel Drive, Front-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 Small Sport Utility Vehicle 2WD 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 Chevrolet Trailblazer emits 287 g/mile of CO2 versus 414 g/mile for the Dodge Durango. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
