Go with the base four-cylinder engine in the 2014 Chevy Equinox and you'll have a fuel-efficient and frugal family wagon. The optional 3.6-liter V-6 is definitely thirstier, and it's up to you to determine whether the lower gas mileage is worth the added power and torque.
The Equinox's EPA ratings of 22 mpg city, 32 highway ratings for the base four-cylinder model with front-wheel drive make it one of the better non-hybrid crossovers for fuel economy. 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 remain unimpressive for those who care about mileage: 16/23 with all-wheel drive or 17/24 with front-wheel drive.
