The lower trims of the Chevy Blazer come standard with a 2.5-liter four-cylinder engine, but an enhanced V6 engine with a displacement of 3.6 liters is also available. At the higher trims, the V6 becomes a standard component. That 3.6L engine has 308 horsepower and 270 pound-feet of torque, with the 2.5L engine achieving 193 horsepower and 188 pound-feet of torque. There are slight differences in the fuel economy, with the larger engine getting 20/26 mpg and the smaller one getting 22/27 mpg. If you plan on heading out in slippery conditions, the 3.6L can come with all-wheel drive.
