The Bugatti Type 39 was a refined, lightweight Grand Prix car introduced in 1925 as a development of the iconic Type 35, aimed at the 1.5-litre racing class. Designed with the same meticulous attention to detail that defined all of Ettore Bugatti’s creations, the Type 39 combined the celebrated chassis dynamics of the Type 35 with a smaller, high-revving engine, making it a favorite among skilled drivers competing in lightweight racing categories.

At the core of the Type 39 was a 1.5-litre straight-eight engine, effectively a scaled-down version of the larger units used in other Type 35 variants. It shared the same advanced layout: single overhead camshaft and three valves per cylinder, which allowed for excellent breathing and smooth high-speed performance. Producing around 55 to 60 horsepower, the engine was mounted in a car that weighed just under 750 kg, giving it an excellent power-to-weight ratio for its class.

The chassis of the Type 39 remained true to the winning formula of its predecessors, with a strong and lightweight frame, a hollow front axle, and Bugatti’s hallmark cast alloy wheels with integrated brake drums. These wheels reduced unsprung weight and improved cooling, making them highly effective for racing conditions. Handling was sharp and precise, and the car could reach top speeds of around 90 mph—exceptional for a 1.5-litre machine of its time.

Visually, the Type 39 was almost indistinguishable from the larger Type 35 models, with its narrow body, signature horseshoe grille, exposed wheels, and gently tapering tail. The cockpit was minimal and driver-focused, equipped with essential instrumentation and seating designed for quick, competitive use. Every element of the design was focused on weight reduction and mechanical efficiency.

The Type 39 found success in international competition, particularly in events where engine capacity was limited, such as the Voiturette class and smaller Grand Prix races. Though not as dominant as the full-size Type 35, it demonstrated the versatility and adaptability of Bugatti’s engineering.

Today, the Bugatti Type 39 is a rare and treasured collector’s car. With its light weight, responsive handling, and exquisite design, it remains a testament to the brilliance of pre-war racing innovation and the vision of Ettore Bugatti.
