center
A type of body/frame construction in which the body of the vehicle, its floor pan and chassis form a single structure. Such a design is generally lighter and more rigid than a vehicle having a separate body and frame.
Where the Volkswagen frame design relies heavily on a strong backbone, the Renault design is much closer to a typical perimeter frame
