Typical features of German racing cars of that time
Technical insights into the fascination of historic Grand Prix cars
The following technical drawings provide an initial insight into the structure and function of a typical racing car engine from the Feldberg race era in the 1930s to 1950s.
They show the interaction of cylinder arrangement, valve control and turbocharging in a high-performance engine of that time.
Particularly noteworthy is the delicate, yet performance-oriented construction, which was often designed for lightweight construction and maximum revving pleasure.
Even back then, such engines achieved impressive performance of up to 50 hp – with a vehicle weight often less than 100 kilograms.
Slim, streamlined body
Freestanding wheels and open wheel arches
Simple independent suspension
Front-engined, rear-wheel-drive
Minimalist cockpit
In-line engine with 6 or 8 cylinders
Compact drivetrain design
Visible connection between suspension and drive
Cylinder – The location where the air-fuel mixture is ignited.
Valves – Control the intake of fresh mixture and the exhaust of exhaust gases.
Supercharger – Forces a larger amount of air into the combustion chamber, increasing power and torque.
Oil pan – Collects and stores lubricating oil to reliably supply all moving parts.
Drum brake – A closed braking system in which brake shoes are pressed against the inside of a drum.
Brake shoe – An element with a friction lining that makes the crucial contact during braking.
Return springs – ensure that the brake shoes return to their original position after braking.
