When Were Unibody Cars Invented

The first popular mass-produced unibody car came in 1928 from DKW (now Audi) with a fabric-covered wood frame. Today, Audi builds cars with an aluminum ’ spaceframe’.

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.

After Nash merged with Hudson Motors to form American Motors Corporation, its Rambler-badged automobiles continued exclusively building variations of the unibody.
