What is one significant advantage of unibody construction in vehicles?

Unibody construction refers to a design where the body and frame of the vehicle are integrated into a single structure. One significant advantage of this method is improved strength and safety. The design allows for a more rigid body structure, which enhances the vehicle's ability to withstand impacts during collisions. This increased rigidity contributes to better crashworthiness, as the energy from a crash is distributed more evenly throughout the vehicle rather than concentrated in one area. Additionally, unibody design often includes crumple zones, which are specifically engineered areas that deform to absorb energy during an impact, providing further protection to occupants.

In contrast, while lower manufacturing costs and increased cargo capacity might be benefits in certain contexts, they do not directly address the core safety features intrinsic to unibody construction. Enhanced engine performance is also unrelated to the structural integrity provided by unibody design, as it primarily relates to the vehicle's powertrain rather than its construction methods.
