While Tesla is not quite there yet, they released a glimpse of the Model 3 body-in-white today. A picture of the Model 3 chassis leaked earlier this year, but this new look is the first official. A Body-in-White (BIW) is the automobile designing (or manufacturing) stage where the car body is formed by assembled metal sheets, and the main components as chassis, power train, doors, etc.
Body in white or BIW refers to the stage in automotive design or automobile manufacturing in which a car body's sheet metal components have been welded together — but before moving parts, the motor, chassis sub-assemblies, or trim have been added and before painting.The name derives from manufacturing practices before steel unibody or monocoque bodies — when automobile bodies were made by outside firms on a separate chassis with an engine, suspension, and fenders attached. The manufacturers built or purchased wooden bodies to bolt onto the frame. The bodies were painted white prior to the final color.This video is targeted to blind users.Attribution:Article text available under CC-BY-SACreative Commons image source in video.
