Car platform


A car platform 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 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.

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 cost by taking advantage of the commonality of the components. However, this also limits their ability to differentiate the products and imposes a risk of losing the tangible uniqueness of the product. The companies have to make a trade-off between reducing their development costs and the degree of differentiation of the products.

One of the first car companies to use this product development approach was General Motors in 1908.

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 front floor, underfloor, engine compartment and frame (reinforcement of underbody). Key mechanical components that define an automobile platform include:

Ford Ka

Fiat Panda

Fiat 500

Fiat Uno

Lancia Ypsilon

Vehicle platform-sharing combined with advanced and flexible-manufacturing technology enables automakers to sharply reduce product development and changeover times, while modular design and assembly allow building a greater variety of vehicles from one basic set of engineered components. Many vendors refer to this as product or vehicle architecture. The concept of product architecture is the scheme by which the function of a product is allocated to physical components.

The use of a platform strategy provides several benefits:

The car platform strategy has become important in new product development and in the innovation process. The finished products have to be responsive to market needs and to demonstrate distinctiveness while — at the same time — they must be developed and produced at low cost. Adopting such a strategy affects the development process and also has an important impact on an automaker's organizational structure. A platform strategy also offers advantages for the globalization process of automobile firms.
