The Ferrari 458 Spider may be the roadster derivative of the 458 Italia coupe, but it was the design of the 458 Spider's aluminum retractable hardtop that was the actual starting point of the project to replace the F430 model line.
About five years ago, Ferrari, in cooperation with its German roof supplier Webasto AG, decided that the replacement for the F430 Spider would have an aluminum retractable hardtop instead of a canvas top. Following that decision, Ferrari began working on the 458 Italia coupe, making sure that the design incorporated fins behind the seats that would later house the mechanism for the 458 Spider's roof system.
The 458 Italia coupe debuted in September 2009 at the Frankfurt auto show and went on sale in February 2010. The 458 Spider debuted two years later, at last month's Frankfurt show.
