An Abarth vehicle is, for its own nature, developed starting from a mass production model, that is built with the objective to make big volumes, allowing a quite easy return of investment but very reduced customization possibilities for the customer. This mainstream model, that usually is a Fiat car, is developed following a specific process, featuring specific rules and timings, based on milestones created around the objectives and the characteristics typical of that kind of car. Clearly an Abarth, being a sporty and technical vehicle, has totally different needs and objectives than the donor car: the Abarth is a niche vehicle, so it produces very reduced volumes (with a subsequent impact on the return of investment, that can be guaranteed only by increasing the price of the car) and contemporarily it needs some specific contents, derived from the racing world, often produced by suppliers specialized in components for track use only, that have to convert them for a road car.
