Description

The Riley Nine Special Le Mans, often referred to simply as the “Riley Le Mans,” was a racing variant of the successful Riley Nine and was designed specifically for endurance events like the famous 24 Hours of Le Mans. Built in the early 1930s, this model became one of Riley’s most iconic racing cars, helping to establish the brand as a major competitor in international motorsports.

The Riley Nine Special Le Mans was powered by a tuned version of Riley’s 1.1-liter (1087 cc) inline-four engine, which featured advanced engineering for its time, such as hemispherical combustion chambers and twin camshafts high in the block. With additional tuning and enhancements, this engine could produce upwards of 50 horsepower, allowing the car to reach speeds of over 90 mph (145 km/h). This impressive performance, especially from such a small engine, made the Riley Le Mans a competitive entry in endurance racing.

In terms of design, the Special Le Mans had a lightweight, aerodynamic body built to optimize performance and stability at high speeds. The car’s body was narrow and low, with a sloping grille, cycle fenders, and a streamlined tail, all of which contributed to its distinctive, purposeful look. This streamlined form allowed it to minimize drag, giving it an edge in long-distance races.

The Riley Nine Special Le Mans quickly proved its capabilities, achieving strong results in events like the 1934 24 Hours of Le Mans, where Riley cars performed exceptionally well against larger and more powerful competitors. The model’s endurance, agility, and reliable performance made it a favorite among privateer racers and Riley enthusiasts, who appreciated its nimble handling and durability.

Today, the Riley Nine Special Le Mans is considered a rare and highly collectible pre-war racing car, revered for its engineering excellence and racing pedigree. It holds a significant place in both Riley’s history and early motorsports, making it a prized possession among classic car collectors and vintage racing enthusiasts.
