Audi e-tron vs Chevrolet Blazer: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Blazer burns about $750 of fuel annually against $950 for the Audi e-tron. 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 Chevrolet Blazer leads in both cycles — 114 mpg city and 95 mpg highway against 78 and 80 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi e-tron is recorded with no distinct engine configurations, the Chevrolet Blazer with 1 (SIDI). Across 8 recorded Audi e-tron configurations and 48 for the Chevrolet Blazer, 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 Audi e-tron is offered with All-Wheel Drive, the Chevrolet Blazer with Front-Wheel Drive, 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 Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 2WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
