Until now, the mechanics of the Volkswagen Group was of the following form. marks flat (to call it somehow) Volkswagen, Seat, Skoda and some Audi models, shared numerous structural elements and mechanical. For example, the MQB platform and the multitude of models that has borne fruit. This made the costs of design and production is kept to grate and very profitable sale.
The problem arises in that Porsche has a platform very similar, the MSB. This has been developed to give life to models with propulsion rear. However, instead of mounting the propeller in longitudinal position what will be the cross-section. In addition, you can change its structure to accommodate variants with all-wheel drive of these models. Therefore, it makes no sense for Audi to follow up with the development of your particular platform.
in Addition, this news might bring as a result that the next Audi A4 to come with propulsion, in place of traction. There I leave it.
