Description
The AC Ace Bristol is a renowned variant of the AC Ace, produced from 1956 to 1963. It is distinguished by its use of the Bristol 2.0-liter inline-six engine, which significantly enhanced the performance of the already capable AC Ace. The Bristol engine was derived from a pre-war BMW design and was known for its durability and power, making the Ace Bristol a favorite among racing enthusiasts.
The engine in the AC Ace Bristol produced 105 horsepower in its standard configuration, with some versions tuned to deliver even more power for competition purposes. This increase in power transformed the driving experience, giving the Ace Bristol a top speed of around 116 mph (187 km/h) and a 0-60 mph time of approximately 9 seconds, impressive figures for the mid-1950s. The engine featured triple Solex carburetors and a unique hemispherical combustion chamber design, contributing to its robust performance and distinctive sound.
The AC Ace Bristol retained the elegant and aerodynamic bodywork of the original AC Ace, with its hand-formed aluminum panels and lightweight tubular frame construction. The car’s low, sleek profile and open-top configuration emphasized its sporty character, while its balanced proportions and clean lines made it a design icon.
The suspension setup was also carried over from the AC Ace, featuring independent front and rear suspension with transverse leaf springs. This setup provided excellent handling and a smooth ride, making the Ace Bristol a joy to drive on both road and track. The braking system consisted of drum brakes on all four wheels, which, while adequate for the time, could be a limiting factor in prolonged high-speed driving or racing scenarios.
Inside, the AC Ace Bristol’s interior was focused on providing a pure driving experience. The cockpit featured simple but functional instrumentation, bucket seats, and minimal luxury, reflecting its racing pedigree. The driver-centric design ensured that all controls were within easy reach, allowing for an engaging and immersive driving experience.
The AC Ace Bristol made a significant impact in motorsport, particularly in endurance racing. It competed in prestigious events such as the 24 Hours of Le Mans, where its combination of lightweight construction, reliable performance, and capable handling made it a formidable competitor in its class. The success of the Ace Bristol in racing further solidified its reputation as a serious sports car.
Today, the AC Ace Bristol is a highly coveted classic, admired for its historical significance, racing heritage, and timeless design. Its connection to the development of the Shelby Cobra adds to its allure, making it one of the most celebrated sports cars of its era.
