Unibody

Unibody is a type of vehicle body construction in which the outer skin, roof, and floor are formed and assembled to produce a single unit providing structural strength and rigidity. This concept was introduced in the 1920’s but was not widely used in mass-produced automobiles until the late 1970’s. Prior to this time, vehicle bodies were built and bolted to separate steel chassis. Conventional pickup trucks are still built in this manner.
