Chevrolet Trailblazer vs Mercedes-Benz GLC-Class: what the numbers mean

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 $2,600 for the Mercedes-Benz GLC-Class. 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 versus highway split: the Chevrolet Trailblazer is the stronger commuter at 30 mpg city, while the Mercedes-Benz GLC-Class pulls ahead on the interstate at 33 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the Chevrolet Trailblazer is recorded with 2 distinct engine configurations (SIDI, SIDI; FFV), the Mercedes-Benz GLC-Class with 3 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 17 recorded Chevrolet Trailblazer configurations and 72 for the Mercedes-Benz GLC-Class, 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 Mercedes-Benz GLC-Class with Rear-Wheel Drive, 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 Small Sport Utility Vehicle 2WD 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 Mercedes-Benz GLC-Class emits 84 g/mile of CO2 versus 287 g/mile for the Chevrolet Trailblazer. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
