Chevrolet Blazer vs Tesla Model Y: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Tesla Model Y burns about $550 of fuel annually against $750 for the Chevrolet Blazer. 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 Tesla Model Y leads in both cycles — 148 mpg city and 129 mpg highway against 114 and 95 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Blazer is recorded with 1 distinct engine configuration (SIDI), the Tesla Model Y with no. Across 48 recorded Chevrolet Blazer configurations and 27 for the Tesla Model Y, 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 Y with All-Wheel Drive, Rear-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.
