- Body Frame Integral
Body frame integral (BFI) is a methodology for manufacturing within the automotive industry. It has become the main technique for chassis assembly for most vehicles except trucks and large
sport utility vehicle s, replacing the traditional approach ofbody-on-frame (BOF).BOF utilizes an independent frame that is used to connect the suspension to the body frame. The main advantage of this is that soft mounts are used to reasonably isolate the body from the vibrations endured by both the frame and the suspension system. BFI was developed for the main purposes of reducing weight and drag, as well as lowering the center of gravity. Front end cradles are still used in BFI, which allows soft mounts to be implemented in the engine compartment. However, most rear ends are hard mounted, but technological advancements allow the associated effects of
noise, vibration, and harshness to be suitably managed.Advantages and disadvantages
