Assuming you've got access to the IIS Manager for that website, create a virtual directory called "360modena" within the ferrari folder. Then configure the virtual folder to be a redirection to a url and specify the url as /voiture/ferrari/360modena.aspx.
If you don't have access to the IIS Manager, you can create a folder called "360modena" below the ferrari folder. Then, in that folder, create a default.asp page that just calls Response.Redirect("/voiture/ferrari/360modena.aspx").
