Because a supercharger is inherently parasitic. When your new brand image is based on "Efficent Dynamics" it just doesn't provide the desired image. A turbo is efficient in the sense that its only utilizing "waste" energy to fuel engine performance. Whereas the supercharger adds power but doesn't add efficiency. Just my 2 cents.
