Very informative ,the output of the cars is sick for that time!

It's not just the output. These cars were build using intense wind tunnel testing (just like today) and with advanced materials (brought from the aero industry just like today).


For example:

Professor Eberan-Eberhorst, from experience gained by recent wind tunnel experiments, rebuild an Auto Union GP racer destined for breaking speed record. The Auto Union technicians had, by covering the underside of the car with "skirts", in fact created a ground effect car "only" 40 years before the Lotus 78/79.
And thus the generated downforce.






Almost every major breakthru that F1 GP cars experienced in the 50s, 60s and 70s was studied, experimented, theoritized or implemented by the germans on the GP and/or speed record programs.


Mid engined cars (the Auto Unions), the use of wind tunnels, inverted airfoils, ground effects (skirt solution), mecanical fuel injection (the MB W154 of 38/39 was suposed to get this, but Neubauer opposed it; so MB implemented it in the W196 of 54/55), hydraulic braking (Dr. Porsche worked but failed on the cars and unfortunately had to leave to make the VW/beetle), advanced materials, advanced alcohol fuels, cars with elevation (W154) ...

The 1930s were really so crazy, and the technological progress was unbelivable. And the germans were so ahead of their time (by decades).
Formula 1 might have represented a step forward in GP racing history, but also about a dozen step backwards at same time.
