How are SUVs classified?
3 Answers
SUVs are classified based on their size, and can be divided into subcompact SUVs, compact SUVs, midsize SUVs, and full-size SUVs. Their respective body dimensions are as follows: 1. Subcompact SUVs have a wheelbase below 2500mm and a body length less than 4200mm; 2. Compact SUVs have a wheelbase between 2500mm and 2700mm, and a body length between 4200mm and 4600mm; 3. Midsize SUVs have a wheelbase between 2700mm and 2900mm, and a body length between 4600mm and 4800mm; 4. Full-size SUVs have a wheelbase between 2800mm and 3000mm, and a body length between 4800mm and 5000mm.
From a practical car-buying experience perspective, SUV classifications primarily depend on size and functionality. Compact SUVs like the Honda XR-V and Toyota C-HR are around 4.4 meters in length, making them particularly suitable for women commuting in the city, with easy turning and parking. Compact models such as the Honda CR-V and Toyota RAV4 are approximately 4.6 meters long, offering enough rear seat space for three people without feeling cramped, and the trunk can fit a stroller. Mid-size SUVs like the Highlander allow flexible switching between 5-seat and 7-seat configurations, effortlessly accommodating family trips with tents and grills. Full-size SUVs such as the Touareg feature a third row that can seat adults, with a trunk capable of holding four or five suitcases. Finally, professional off-road vehicles like the Wrangler come with high ground clearance and a ladder frame, specifically designed for rock crawling and mud traversing.
Experienced mechanics usually distinguish SUV types by their chassis structure. Most urban SUVs are modified from car platforms, like the Nissan Qashqai which has higher ground clearance but limited off-road capability. True hardcore SUVs feature a ladder frame construction, such as the Toyota Land Cruiser Prado, where the engine and transmission are mounted on steel beams for superior bump resistance. Some hybrid models like the Land Rover Discovery have air suspension for height adjustment but use unibody construction - outperforming urban SUVs off-road while falling short of dedicated off-roaders. The current trend favors crossover designs like the Haval Big Dog, which sports rugged styling but is actually better suited for paved urban roads.
