The Equinox seats five and is available in LS, LT and LTZ models with available all-wheel drive. When equipped with the standard Ecotec 2.4L direct-injected engine, the FWD Equinox achieves an EPA-estimated 32 mpg on the highway. That means a highway-only cruising range of up to 600 miles on a single tank of fuel. For 2012, this engine adds FlexFuel capability on vehicles with federal emissions, meaning it can operate on regular unleaded fuel, E85 ethanol or a combination of both.
