The term "body in white" is widely used inside the automotive industry but little known outside that circle. Essentially, the body in white — or BiW, as automakers say — is a vehicle's backbone, making it a critical component of everything from automotive manufacturing to vehicle rigidity to safety.

Body-in-White Basics
Decades ago, automobile bodies were an assembly of panels bolted to parallel steel-frame rails. This is called body-on-frame construction, and it's still used for many trucks and SUVs.
Today's cars and crossovers are usually built on a unibody, a structural component that serves as both body and frame. If much of this structure's strength is derived from the outer panels rather than the internal support components, it can be called a monocoque.
A body in white is generally defined as the basic skeletal frame and body of an automobile. This shell is devoid of running gear and often includes only the doors, hood, and decklid. The term body in white is derived from the practice of painting unibody shells before delivery to a customer or assembly plant. Often the paint is white, but not always — the real purpose of painting the bare-metal shell is to inhibit rust, so the paint color isn't actually important.

Bodies in white can be valuable to car racers: Getting a vehicle in its skeleton form allows them to build from the ground up and customize everything from the powertrain to the suspension to the interior. But the resulting car will be strictly for the racetrack, as a body in white does not have a vehicle identification number and thus can't be registered for use on public roads.
Auto manufacturers sometimes offer this type of bare-bones version so racing teams can build a machine that conforms to their performance aspirations and the specifications of a particular class, such as the National Hot Rod Association's Super Stock.
