The hood of the F82 M4 GTS is made of carbon-fiber-reinforced plastic and weighs 25% less than the hood made of aluminium on the F82 M4.
The press molded hoods are manufactured using a Double Diaphragm Forming process with tailored composite blanks. Diaphragm forming offers multiple advantages; including blank support during the pressing process, which eliminates the need for preforming as well as more cost effective, simplified tooling which is a clear investment benefit. The Double Diaphragm Forming process gave Läpple the opportunity to capitalize on their sheet metal know-how and to apply it to forming CFRP parts.
