The Equinox and its twin, the GMC Terrain, straddle the small and midsized SUV categories. They have a taut, yet supple and controlled, ride with responsive and secure handling. But both the 3.6-liter V6 and the more fuel-efficient four-cylinder feel sluggish. The transmission blunts the performance of the V6, and fuel economy is mediocre. The 2016 models get a smattering of cosmetic updates, and additional advanced safety features, including available blind-spot monitoring and rear cross-traffic alert, join the forward-collision and lane-departure warning systems. A rear-view camera is standard. Reliability has been above average, but the Equinox scored too low in our testing for us to recommend.
