This comprehensive article delves into every aspect of the Ferrari 166 S—its design, engineering, racing achievements, market impact, and legacy. Join us on a journey to understand how this iconic car laid the foundation for Ferrari’s reputation as one of the most revered automakers in the world.

Post-War Italy and the Birth of Ferrari

The late 1940s were a transformative period for Italy and its nascent automotive industry. Emerging from the devastation of World War II, Italian engineers and designers sought to restore their country’s reputation for craftsmanship and innovation. Among them was Enzo Ferrari, a man whose vision for creating the ultimate racing machines led to the establishment of Scuderia Ferrari in 1947.

The Ferrari 166 S was born out of this fervent drive for excellence. It followed the 125 S and the 159 S, refining their concepts while introducing significant advancements in performance and design. The “166” designation referred to the displacement of each cylinder in cubic centimeters, while the “S” stood for “Sport,” emphasizing the car’s dual-purpose nature as both a racing machine and a road car.

Design Philosophy

The 166 S was designed with a clear goal: to dominate on the track and captivate on the road. Ferrari collaborated with some of Italy’s most renowned coachbuilders, including Touring and Vignale, to create a car that was not only functional but also beautiful. The resulting designs set the standard for Ferrari’s aesthetic language, blending elegance with aggression.

The Colombo V12 Engine

At the heart of the Ferrari 166 S was the Colombo-designed 2.0-liter V12 engine. This engine, developed by legendary engineer Gioachino Colombo, was a masterpiece of efficiency and power. Producing up to 110 horsepower at 6,000 rpm, the V12 was compact, lightweight, and capable of high-revving performance.

The engine featured a single overhead camshaft per cylinder bank, a wet sump lubrication system, and three Weber 32 DCF carburetors. These components worked in harmony to deliver smooth power delivery and exceptional reliability—qualities that were critical for both racing and long-distance touring.

Chassis and Suspension

The 166 S utilized a tubular steel chassis, a hallmark of Ferrari’s early engineering approach. This frame provided the rigidity needed for precise handling while keeping weight to a minimum. The suspension system included independent double wishbones at the front and a live axle with semi-elliptic leaf springs at the rear. This setup offered a balance between comfort and performance, ensuring the car could handle the demands of racing as well as the open road.

Transmission and Drivetrain

A five-speed manual transmission delivered power to the rear wheels, providing a level of control that was unmatched by many of the car’s contemporaries. The gearbox was praised for its precision, allowing drivers to fully exploit the engine’s capabilities.

Mille Miglia Triumph

The Ferrari 166 S made its mark in motorsport with an impressive victory at the 1948 Mille Miglia, driven by Clemente Biondetti and Giuseppe Navone. This grueling 1,000-mile race across Italy tested the limits of endurance and performance, and the 166 S rose to the challenge, showcasing its reliability and speed.

Success at Le Mans

In 1949, a 166 S variant achieved Ferrari’s first victory at the 24 Hours of Le Mans. Luigi Chinetti and Lord Selsdon piloted the car to an extraordinary win, cementing Ferrari’s reputation on the global stage. This victory was a turning point for Ferrari, establishing the brand as a dominant force in endurance racing.

Other Achievements

The 166 S’s success wasn’t limited to these marquee events. It also claimed victories in hill climbs, road races, and circuit events across Europe. The car’s versatility and performance made it a favorite among privateer racers, further enhancing Ferrari’s prestige.

Exterior Styling

The Ferrari 166 S’s design varied depending on the coachbuilder, but all versions shared a commitment to aerodynamic efficiency and visual appeal. Touring’s Barchetta (“little boat”) body was particularly iconic, with its flowing lines, minimalistic grille, and open cockpit. This design not only reduced weight but also captured the imagination of enthusiasts and collectors.

Interior Features

The interior of the 166 S was purpose-built, reflecting its racing DNA. Sparse yet functional, the cabin featured lightweight bucket seats, a simple dashboard with analog gauges, and minimal trim. Despite its spartan nature, the interior exuded a sense of craftsmanship and attention to detail.

Limited Production

Ferrari produced only 39 examples of the 166 S between 1948 and 1950, making it one of the rarest and most sought-after Ferraris. Each car was hand-built, with variations in bodywork and specifications based on the preferences of its owner.

Customer Appeal

The 166 S attracted a clientele that valued exclusivity, performance, and style. It was a car for the discerning enthusiast, offering a level of sophistication and capability that was unmatched in its era.

Influence on Future Models

The Ferrari 166 S set the template for future Ferrari sports cars, from the 250 GT to the modern-day 812 Superfast. Its combination of a high-revving V12 engine, lightweight chassis, and stunning design became hallmarks of the brand.

A Collector’s Dream

Today, the Ferrari 166 S is a prized possession for collectors. Its rarity, historical significance, and racing pedigree make it one of the most valuable Ferraris ever produced. Restored examples often fetch millions of dollars at auctions, a testament to its enduring appeal.


The Ferrari 166 S is more than just a car; it is a cornerstone of Ferrari’s legacy. From its groundbreaking engineering to its racing triumphs and timeless design, the 166 S embodies the spirit of innovation and excellence that defines Ferrari. It remains a symbol of post-war optimism and the enduring allure of Italian automotive craftsmanship.

As a piece of history and a work of art, the Ferrari 166 S continues to inspire admiration and respect. Its legacy lives on, not only in the cars that bear the Ferrari name today but also in the hearts of enthusiasts who recognize it as one of the greatest cars ever built.
