orm is a shared set of common design, engineering, and production efforts, as well as major components, over a number of outwardly distinct models and even types of cars, often from different, but somewhat related, marques. It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms. This further allows companies to create distinct models from a design perspective on similar underpinnings. A car platform is not to be confused with a platform chassis, although such a chassis can be part of an automobile's design platform, as noted below. Definition and benefits A basic definition of a platform in cars, from a technical point of view, includes underbody and suspensions (with axles) — where the underbody is made of the front floor, rear floor, engine compartment, and frame (reinforcement of underbody). Key mechanical components that define an automobile platform include: The floorpan, which serves as a foundation for the chassis and other structural and mechanical components Front and rear axles and the distance between them - wheelbase Steering mechanism and type of power steering Type of front and rear suspensions Placement and choice of engine and other powertrain components Platform sharing is a product development method where different products and the brand attached share the same components. The purpose with platform sharing is to reduce the cost and have a more efficient product development process. The companies gain on reduced procurement costs by taking advantage of the commonality of the components. However, this also limits their abi
