The Chevrolet Equinox underwent a complete transformation for the 2018 model year. It received a handsome new exterior, a vastly improve and more tech-savvy interior, and a few new choices under the hood. The most surprising engine inclusion is GM’s 1.6-liter turbodiesel four-cylinder. It’s the same turbodiesel available in the Chevy Cruze sedan and comes with the same 137 horsepower and 240 pound-feet of torque. In the Cruze, the engine returns an impressive 47 mpg highway when mated to the nine-speed automatic transmission. The question now, though, is how well the turbodiesel performs in the larger Equinox.
