The 2013 Chevrolet Equinox is a frugal, efficient pick, provided you get the base four-cylinder engine. The larger 3.6-liter V-6 that's been subbed in for 2013 in place of the former 3.0-liter isn't any thirstier--but it's not significantly more fuel-efficient, either.
With its 22 mpg city, 32 highway ratings for the base four-cylinder model with front-wheel drive, the Equinox is among the highest-mileage non-hybrid vehicles in this class. Stepping up to AWD, mileage drops to 20/29, still good for a comfortably sized crossover. All four-cylinder models now come with an 'Eco' button which activates a mode with more conservative air-conditioning operation, earlier torque converter lockup, and different shift points.
EPA ratings with the new, larger 301-hp, 3.6-liter V-6 weren't yet confirmed at the time of posting, but last year when the closely related Cadillac SRX got this engine its ratings improved slightly to 16/23 with AWD or 17/24 with front-wheel drive. If they're the same for the Equinox, that's the same as last year for the front-wheel-drive versions and a slight improvement with AWD.
