Ferrari has unveiled a special £2 million spin-off model based on the 458 Spider supercar – but has bizarrely named it the Sergio.

Just six of the roofless Sergios will be built, bearing the forename of the great Sergio Pininfarina, who designed some of the most beautiful Ferraris ever produced. The design house started by the man himself has penned the latest design.

Despite the odd-sounding name, the Ferrari Sergio will use the latest version of the high-revving 4.5-litre V8 found in all 458s, albeit with an astonishing 597bhp.

The car takes inspiration from Ferraris of the 1960s and 1970s, combining it with the cutting-edge aerodynamics that the Italian firm has worked into its 21st Century identity.

Each Sergio was pre-sold to an existing Ferrari connoisseur, with each buyer then able to customise the incredibly rare machine to their specification.

Ferrari said: “Each one of the six Ferrari Sergios was configured by its owner in dedicated sessions at the tailor-made atelier in Maranello where clients are invited to personalise their cars to their own individual tastes.

“The atelier offers enormous freedom of choice in terms of colours, materials and finishes. As a result, every detail is extremely exclusive, thereby continuing the Prancing Horse tradition begun in the 1950s and 1960s of creating bespoke cars minutely tailored to each client’s wishes.”
