Abstract

A method of designing and manufacturing vehicle bodies includes establishing a common, standardized interface system for attaching vehicle bodies to vehicle chassis wherein connection components are arranged in a predetermined spatial relationship on the bodies and chassis to facilitate selective attachment of any of a plurality of different body types to the chassis. A plurality of different bodies are designed and manufactured having different body types and configured to conform to the standardized interface system for attachment to chassis which also conform to the standardized interface system. The vehicle bodies can be produced independently of the chassis. Eliminating the chassis and its hardware from the body manufacturing process can reduce current vehicle manufacturing plant sizes and system complexity. The result is an enabler to produce many vehicle bodies that can be distributed directly to dealers, customers, etc. either with or without a specified rolling platform. Smaller and customized production runs are enabled, as well as localized manufacturing plants, reduced investment costs and faster response time for order to delivery.
