Mini SUV is a class of small sport utility vehicles with a length under mm (in). This class should not be confused with compact SUV, which refers to slightly larger vehicles, from . Early mini SUVs were off-road vehicles built on body-on-frame chassis, such as the Jeep Wrangler and Suzuki Samurai. Earlier mini SUVs are still often used due to their off-road prowess and more manageable size on the trail (for example, a large SUV might not fit in the narrower parts of the trail). The most capable off-road vehicles built earlier were mini SUVs due to them having been built for off-roading, while the trend for larger four-door SUV since the introduction of the Jeep Cherokee and the Ford Explorer has increasingly been toward family hauling and on-road use rather than hard off-roading.
