The Aston Martin DB3S

The Aston Martin DB3S stands as one of the most iconic and historically significant sports racing cars ever produced. It was built during a golden era of motorsport, the DB3S combined elegant design with competitive engineering, leaving a lasting legacy that has influenced Aston Martin’s identity for decades.

The story of the DB3S begins in the early 1950s, a critical period for Aston Martin and HWM. At this point, they were operating out of Feltham, a few miles away from our dealership. After World War II, the company was seeking a strong presence in international motorsport, especially at prestigious events like the 24 Hours of Le Mans. Under the ownership of David Brown (whose initials “DB” famously prefix the cars). In 1950, our founder, George Abecassis took class victory at Le Mans with Lance Macklin in a DB2. This was the start of HWM’s dealership journey as we were awarded the franchise the following year.

Encouraged by the performance, Aston Martin took things forward and developed the DB3, a sports racing car launched in 1951. The DB3, while innovative, proved to be too heavy and lacked the speed necessary to consistently challenge rivals like Jaguar and Ferrari. Recognizing the shortcomings of the DB3, Aston Martin’s chief engineer, Eberan von Eberhorst, was tasked with creating a new, lighter, and faster vehicle. His efforts, alongside the work of chief designer Frank Feeley and engineers like William Watson, led to the development of the DB3S. Incidentally, Frank also helped George design the one of one HWM Coupe in later years.

Introduced in 1953, the DB3S was essentially a refined and optimized version of its predecessor. It retained the 2.9-liter inline-six engine derived from the Lagonda engine designed by W.O. Bentley, but with significant improvements to weight distribution, aerodynamics, and overall performance. It featured a lightweight tubular frame chassis and aluminum bodywork. The design was both functional and beautiful, characterized by its low, curvaceous lines and elegant proportions. Aston Martin also introduced important aerodynamic refinements compared to the more boxy DB3. Feeley’s bodywork was shaped for maximum efficiency on fast circuits, and although early models had issues with high-speed stability, later adjustments corrected many of these flaws.

Power came from a straight-six engine producing around 180–210 horsepower, depending on configuration and tuning. This was paired with a four-speed manual gearbox. While not the most powerful engine on the grid, the DB3S’s lightweight construction and superb handling made it extremely competitive, especially on twisting circuits and in endurance racing where reliability mattered as much as outright speed.

Two versions of the DB3S were produced: works cars (designed for the Aston Martin factory team) and customer cars, which were sold to private racers. The factory cars often featured more advanced specifications, as the company constantly developed improvements based on racing experiences. We even have a few photos of customer cars knocking around at the dealership back in the day.

The DB3S quickly proved itself on the track. In its debut year of 1953, the car competed at Le Mans, although success initially eluded it. Mechanical failures and challenging conditions prevented a win, but the car showed strong potential. Over the next few years, the DB3S would become a formidable competitor.

One of the DB3S’s most impressive performances came at the 1955 24 Hours of Le Mans, where Aston Martin finished 2nd and 5th overall, behind the dominant Mercedes-Benz 300 SLR. That result marked Aston Martin’s best showing at the famous race up to that point and reinforced the DB3S’s status as a true endurance racing machine.

The car also saw success in other prestigious events such as the Goodwood Nine Hours, the Sebring 12 Hours, and the RAC Tourist Trophy races. Legendary drivers, including Stirling Moss, Peter Collins, Roy Salvadori, and Carroll Shelby, piloted the DB3S to victory and added to its growing legend.

Notably, the DB3S helped lay the groundwork for Aston Martin’s ultimate triumph at Le Mans in 1959 with the DBR1. Many of the lessons learned in the heat of competition with the DB3S directly influenced the development of subsequent models.

Aston Martin produced 31 examples of the DB3S between 1953 and 1956. Of these, 11 were works cars (used by the factory team), and 20 were customer cars. Some customer cars featured slight modifications, including the option for coupe bodywork, though these designs were not as aerodynamically successful as the open-top versions. The DB3S also enjoyed popularity among privateers and wealthy enthusiasts, who appreciated its performance and exclusivity. Many customer cars continued racing into the late 1950s and even beyond, as vintage racing grew in popularity.

Today, original DB3S models are highly prized by collectors. Their combination of rarity, beauty, historical significance, and competition pedigree makes them some of the most valuable Aston Martins ever built. Auction prices for well-documented DB3S cars can easily reach several million dollars, reflecting their status in automotive history.

The DB3S was crucial in establishing Aston Martin’s reputation as a manufacturer capable of building world-class racing cars. Although the DB3S never won Le Mans outright, it demonstrated that Aston Martin could consistently compete at the highest levels against more established and better-funded rivals. Furthermore, the DB3S set a design and engineering philosophy that would guide Aston Martin in the years to come: a focus on lightweight construction, elegant design, and reliability over brute force. This philosophy reached its peak with the later DBR1, which finally delivered Aston Martin a Le Mans victory in 1959.

The Aston Martin DB3S represents a key chapter in the history of not only Aston Martin but also of postwar motorsport. As a beautifully crafted, highly capable racing car, it embodied the aspirations and challenges of a small manufacturer trying to carve out its place among giants. Through its successes and its enduring influence, the DB3S helped shape the identity of Aston Martin and left an indelible mark on the world of sports car racing. Its legacy continues to inspire admiration among enthusiasts, collectors, and historians, ensuring that the DB3S will be remembered as one of the true greats of its era.
