By the 1960s, unibody construction in passenger cars had become common, and the trend to unibody for passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most pickups continue to use a separate frame as their chassis. The main functions of a frame in a motor vehicle are:
Unibody. This engineering approach of a vehicle describes “of a vehicle, a one-piece frame and body structure”. A type of body/frame construction in which the body of the vehicle, its floor plan and chassis form a single structure. Such a design is generally lighter and more rigid than a vehicle having a separate body and frame.
By 1960, the unitized body design was used by Detroit’s Big Three on their compact cars ( Ford Falcon, Plymouth Valiant, and Chevrolet Corvair ). After Nash merged with Hudson Motors to form American Motors Corporation, its Rambler-badged automobiles continued exclusively building variations of the unibody.
