A crossover is an automobile based on a unibody construction, meaning the body and frame are one unit. It is built on a unibody platform similar to a car, but with higher ground clearance and added features like all-wheel-drive (AWD) or four-wheel-drive (4WD). Crossovers usually offer better fuel economy than an SUV and have a more car-like driving experience.
An SUV, on the other hand, is built on a body-on-frame construction, meaning the body and frame are separate components. It is usually larger, heavier and offers greater towing capacity than a crossover. SUVs have a stronger body that is better suited for off-road driving, and they often have more powerful engines and rugged features. Most SUVs also come with AWD or 4WD features. However, they tend to have a lower fuel efficiency than crossovers.
