Who wanted it, and who made it? Enzo Ferrari did, aiming to secure a victorious entry in the World Manufacturer’s Championship (formerly known as the Formula 1 World Driver’s Championship), which transitioned from sports cars to grand touring cars.

The initial project was the work of engineer Giotto Bizzarrini, who, starting from the Ferrari 250 GTO short wheelbase, moved the engine towards the centre of the chassis and stiffened the entire structure. During development, Bizzarrini left Ferrari, and the project’s finalization, with significant improvements, was carried out by Mauro Forghieri.

When: between 1960 and 1961, with its debut at the 1962 12 Hours of Sebring, where it immediately triumphed in the GT class (Gran Turismo).

The car’s potential had already been seen during testing at the Monza racetrack in 1961, where the new GT had lapped even faster than Formula 1 cars (which, in those years, had 1500cc engines by regulation).

Where: in Maranello and Modena, where the famous coachbuilder Scaglietti helped Bizzarrini find the most effective forms for a competition car. During this creative process, the distinctive front and side vents that now define the car’s appearance emerged. The first car built, without a rear spoiler and with a different front end, was nicknamed “Papera” (duck) because it resembled a duck’s beak.

It was Forghieri who introduced the rear spoiler to increase rear-end grip and extended the nose to improve front-end grip.

How: through continuous road and track testing, with an eye towards producing the 100 units necessary for GT homologation. In reality, only 36 were made because Ferrari managed, not without effort, to have the new car accepted as part of the 250 GT short wheelbase family. Hence, the origin of the name. When the telegram arrived at the team that was already at Sebring, announcing that the car had been homologated, in the classic concise formulation of those times (every word cost money in a telegram!), it read “250GT Omologata”. That’s how it became the GTO.

Why: because the V12 engine designed by Gioachino Colombo, which produced 300 horsepower and featured six twin-choke carburettors, a dry sump, and a 7,000 rpm redline, had the potential to secure success – even during an era when engines were transitioning to the rear configuration. Remember that the constraint of the front engine came from the objective of homologating the car as an extension of the 250 SWB. The GTO’s trophy collection is truly impressive: it won everything, everywhere.
