The V12 Engine That Defined Lamborghini's Legacy

2022 marked a special year for Lamborghini, celebrating its legendary V12 engine—a 12-cylinder powerhouse that has powered numerous iconic models over nearly 60 years of distinguished history. This engine became a symbol of technological innovation, forward-thinking vision, and exceptional engineering, laying the foundation for Lamborghini’s defining heritage.

Before transitioning into hybrid technology in 2023 with the launch of its first production model in an expanded lineup, Lamborghini pays tribute to its most celebrated engine by revisiting the cars that showcased its brilliance. The first vehicle to roll off the production line at Sant’Agata Bolognese in 1964 was the 350 GT. Recently, this historic car was brought to the historical center in Bologna, Italy, for a striking comparison with the latest model from the brand’s lineage featuring a V12 engine: the Aventador Ultimae.

To design the engine, Ferruccio Lamborghini enlisted an exceptional external consultant—engineer Giusto Pizzarini, born in Quercianella (province of Livorno) in 1926, who remains one of the greatest engine designers of all time. Pizzarini was passionate about racing and dreamed of creating an engine for Formula 1.

The agreement with Lamborghini was straightforward and laid the groundwork for something truly extraordinary: a 12-cylinder V-engine with a displacement of 3.5 liters and immense power—no less than 350 horsepower.

To provide Pizzarini with a unique incentive, Lamborghini added a bonus payment for every additional 10 horsepower the new engine achieved. After the engine was first tested in July 1963, the results were astonishing—delivering 360 horsepower at 9,000 RPM. Ferruccio Lamborghini honored his promise, including the bonus for extra power, but soon realized he faced a dilemma. In reality, Pizzarini had designed a Formula 1-level engine unsuitable for road vehicles or mass production.

Lamborghini then tasked Paolo Stanzani—one of the most renowned engineers in the company’s history—with refining the engine to make it more practical. Stanzani successfully preserved the engine’s outstanding performance while making it suitable for everyday driving at moderate and low speeds. Crucially, he did not alter the core technical specifications, many of which became pioneering features for a production vehicle. The engine ultimately delivered 280 horsepower at 6,500 RPM—more than enough to propel the 350 GT, Lamborghini’s first production model launched in 1964, enabling it to reach a top speed exceeding 250 km/h.

The first 350 GT was delivered to a drum maker from Livorno, Gambierio Giusti. This marked the beginning of a strong relationship between Lamborghini and the entertainment world, as many well-known actors and musicians became passionate customers of the brand.

This very car is now the oldest surviving production Lamborghini ever made. It has been meticulously restored and officially authenticated by the Polo Storico department of Lamborghini—the dedicated unit responsible for preserving the brand’s classic vehicles and safeguarding its historical legacy. The car won the 'Best in Show' award at the Lamborghini and Design competition held in Trieste in 2019, organized by Lamborghini Polo Storico.

In 1967, the 350 GT made a cinematic appearance in the Columbia Pictures film Kill Me Quick, I’m Cold, written and directed by Francesco Maselli. It served as the primary vehicle for the main character, portrayed by the acclaimed actress Monica Vitti and the distinguished actor Jean Sorel.

Since its debut in 1964, the Lamborghini V12 engine has become a benchmark for torque, smoothness, reliability, and durability. With only minor adjustments, this engine remained in production until the late 1990s, evolving to a 7-liter displacement and generating over 500 horsepower before undergoing major structural revisions.
