Ferrari's new drop-top incorporates a number of important technical features which give hints of the auto's F1 pedigree, beginning with the inventive electronic differential ( E-diff ) - first developed by the racing division for the Scuderia's all-conquering F1 cars - which improves traction and roadholding under all conditions. The Spider also includes the steering wheel-mounted rotary switch, known to the Scuderia's drivers as the 'manettino', which allows the car's set-up to be altered simply and fast.
