The Toyota 4Runner is a mid-size sport utility vehicle (SUV) produced by the Japanese manufacturer Toyota and sold throughout the world from 1984 to present. In Japan it was known as the Toyota Hilux Surf. The original 4Runner was a compact SUV and little more than a Toyota pickup truck with a fiberglass shell over the bed, but the model has since undergone significant independent development into a cross between a compact and a mid-size SUV.
