A "Unibody" is a design and manufacturing technique where the outer shell of a product, such as a laptop or smartphone, is made from a single piece of material. This approach enhances structural integrity and reduces the number of parts needed, leading to a lighter and more durable product. In the automotive industry, a unibody construction means that the body and frame of a vehicle are combined into one cohesive structure. This design improves safety and performance by distributing stress more evenly during impacts, making unibody vehicles generally more efficient and easier to manufacture.
