The one-off is based on the 599 GTB Fiorano and was styled internally by Ferrari Design and engineered and built in-house.
The main new element is a carbon-fibre rotating hard-top which incorporates a rear screen and a rotating mechanism similar to the that adopted on the 575-based Superamerica.
The boot area is entirely new to house the roof when open, and is now in carbon-fibre with a design optimized to reduce drag and increase rear downforce.
The rear buttresses are body-colored, integral with the rear wheelarches, and incorporate rear quarterlights. The side view is further distinguished by double air vents on the front wing.
The Ferrari Superamerica 45 also features a specific chromed front grille and special burnished aluminum A-pillars, wing mirrors and door handles.
The wheels are body-coloured with a contrasting diamond finish to the spokes.
The roof and other carbon-fiber elements of the bodywork – front splitter, side skirts and rear diffuser – are in a special contrasting darker blue, a theme that is carried over to the cockpit which features dark blue carbon-fibre dash trim and driver zone.
The interior also features leather trim and a latest-generation touch-screen infotainment system.
