Chevrolet Blazer vs Tesla Model X: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model X burns about $700 of fuel annually against $750 for the Chevrolet Blazer. That $50 yearly gap compounds to roughly $250 over five years and $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 versus highway split: the Chevrolet Blazer is the stronger commuter at 114 mpg city, while the Tesla Model X pulls ahead on the interstate at 101 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 Blazer is recorded with 1 distinct engine configuration (SIDI), the Tesla Model X with no. Across 48 recorded Chevrolet Blazer configurations and 41 for the Tesla Model X, 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 Blazer is offered with Front-Wheel Drive, All-Wheel Drive, Rear-Wheel Drive, the Tesla Model X with All-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.
