(Relaxnews) - To mark the 60th anniversary of its partnership with design firm Pininfarina, Ferrari is building six bespoke supercars based on the Sergio concept car that wowed the crowds at the Geneva motor show in 2013.

When Pininfarina took the wraps off its incredibly bold, incredibly stripped back Sergio concept at the Geneva motor show in 2013 the reaction was such that it looked that it would only be a matter of time until Ferrari bent to its biggest fans' wishes and put the roadster into limited production.

The concept car -- an extreme barchetta by dint of its lack of roof and windshield -- was created by the Italian design studio to celebrate the 60th year of its partnership with Ferrari and to remember the achievements of Sergio Pininfarina. Sergio led the design studio from 1966 to 2001 following the death of its founder, his father, and remained on the board until his own passing in 2012.

Sergio's flair for exterior aesthetics was only matched by his deep-rooted understanding of engineering. It was his badgering of Enzo Ferrari that led to Ferrari adopting a mid-engine layout and is why the two companies are now synonymous with each other; every Ferrari that rolls out of the Modena plant carries both the Prancing Horse and Pininfarina badges.

The production version of the Sergio is surprisingly close to the concept model in terms of appearance and proportions. It is a permanent open-top roadster however, unlike the concept model, Ferrari has opted for a windshield.

This nod to comfort has not in any way diluted its track focus. Every angle, curve and duct of its exterior is about channeling or maximizing performance, but without offending the eye. And inside it's a similar story, the cockpit is focused on simplicity as to not distract the driver.

And concentration will be needed in massive quantities. Under the hood is Ferrari's now legendary 605hp normally aspirated 5-liter V8. The same engine that catapults the 458 Italia from a standstill to 100km/h in 3 seconds and which promises even more dynamism in this body shell.

The first Ferrari Sergio is destined for the SBH Royal Auto Gallery in the UAE, at Abu Dhabi's Yas Marina Circuit, and each of the remaining five examples are currently being hand-built based on their clients' individual tastes.
