As World War II began to reshape the global landscape, an extraordinary automobile emerged from the Aston Martin factory – the Speed Model Type C of 1940.
The Type C variant looked different from typical Aston Martins. It had a streamlined body with a wide, flowing nose and long, tapered tail. Sleek wings fully covered the wheels, reducing air resistance. Headlamps sat behind the rounded radiator shell, adding to its unique look.
The heart of this machine was a newly developed 2-liter engine, churning out about 125 horsepower – a 25% increase over its forerunner. This powerplant featured larger carburetors, cams with increased lift, and a dry sump system, all contributing to its impressive output.
The Speed Model’s framework was an engineering feat for its time. Its wheelbase measured one inch less than earlier models, yet the track width grew by two inches. This setup improved the car’s handling, allowing drivers to push its performance boundaries.
A standout feature was the braking system. Made by Lockheed, it used two separate hydraulic circuits for front and rear, providing a safety backup. This arrangement outperformed many cars with drum brakes until disc brakes appeared years later.
The gearbox was another highlight. Built to easily handle up to 200 horsepower, it had close ratios and constant mesh gears on input and main shafts. This design allowed for quick gear shifts, a big plus in racing.
Aston Martin made just 23 full competition-spec Speed Models, and only eight got the Type C body. This scarcity has made the model highly prized by collectors and enthusiasts.
Performance-wise, the Speed Model Type C was impressive. Its aerodynamic shape let it go almost 20 mph faster than versions with exposed wheels. This edge showed at the Donington Tourist Trophy race, where it won its class and came in second overall with St. John Horsfall driving.
Rivals to the Aston Martin Speed Model Type C included other British sports cars of the time, like certain Jaguar and MG models. However, the Speed Model’s mix of performance, handling, and aerodynamic design set it apart from many competitors.
The 1940 Aston Martin Speed Model Type C is a fascinating piece of car history. It shows off the creativity and determination of Aston Martin’s engineers during a tough time, resulting in a vehicle that blended cutting-edge tech with great performance.
