Question: are trailblazers good on gas?
Answer: The most efficient Trailblazer, according to the EPA, is the front-wheel drive model with the larger 1.3-liter three-cylinder, which earned ratings of 29 mpg city, 33 mpg highway, and 31 mpg combined. Upgrading to all-wheel drive reduces those numbers to 26 mpg city, 30 mpg highway, and 28 mpg combined.
