The strong, stiff, and lightweight nature of sandwich panels make them an ideal fit for numerous applications. In yet another example, Business Wire reports that the new Ferrari JBL speakers utilize a sandwich construction:

In the quest for 100+ mpg cars, the weight needs to decrease, and it is no suprise composites will help do this. AutoBlog.com reports on Aptera’s new concept car and it notes that they are using composite sandwich panels in the construction.
Last I heard, Aptera was one of the final nine cars still in the running for the Automotive X-Prize competition. Good luck Aptera, if you win, I am sure it is because of the composite sandwich panels…
