The Ford Explorer Sport Trac, sometimes referred to as simply the Ford Sport Trac, is a mid-size sport utility truck (SUT) sold mostly in North America produced by Ford from 2000 through 2010. The Sport Trac was based on the Ford Explorer SUV. The Sport Trac fell between the Ranger and Ford F-Series in Ford's truck lineup, based on capability and price. It competed with other mid-size SUTs, trucks and SUVs, such as the mid-size Honda Ridgeline SUT and even the larger full-size Chevrolet Avalanche SUT. Remote keyless entry systems are an available option for all Ford Explorer Sport Trac models and are a standard feature on all newer models.
