Curb weight is the total weight of a vehicle without passengers or cargo. Larger vehicles usually have higher curb weights due to their bigger frames, stronger materials, and extra features.
Wheelbase length is the distance between the centers of the front and rear wheels of a vehicle. It affects stability and ride quality. Usually a longer wheelbase means better stability and a smoother ride, while a shorter one makes it easier to maneuver a vehicle.
Track width is the distance between the centerlines of the left and right wheels on the same axle. A wider track width usually improves stability and enhances cornering capability. This reduces the risk of rollovers. However, a very wide track can make maneuvering harder.
Ground clearance is the distance between the lowest part of a vehicle and the ground. A higher clearance is better for off-road driving, while a lower clearance improves aerodynamics, handling and stability.
Front and rear overhangs are the parts of a car that extend past the wheels at the front and back. Shorter overhangs actually help with better handling and off-road driving, while longer overhangs are known to improve aerodynamics and cargo or storage space.
Though used interchangeably at times, they are not exactly the same. Axle width is the distance between the left and right wheel hubs on an axle, while track width is the distance between the centerlines of the wheels on the same axle (or simply, the distance between the center of the left and right tires).
Cargo space is the area in a vehicle designed for carrying items (storage area). It is measured in cubic feet or liters.
Turning radius is basically the smallest circular turn a vehicle can make. A smaller turning radius makes it easier to navigate tight spaces and park. It plays a crucial role in vehicle maneuverability and safety.
Maneuverability, simply put, is the ability of a vehicle to move and steer easily while in motion (maneuver). So a car with good maneuverability can turn, change direction, and fit into tight spaces easily.
Payload capacity is the maximum weight a vehicle can carry (this includes passengers and cargo) while towing capacity is the maximum weight a vehicle can pull (like a trailer or boat). They're different because payload affects the vehicle's weight, and towing involves pulling external weight.
