The legendary Juan Fangio drove this car. These prototype cars back in the day did not have air conditioning like modern race cars, so basic venting was all there was for airflow through the cockpit.
The wing mounts are a bit interesting; the upper element is attached to mounts that bolt to the lower mounts for the lower mounts. I was expecting the mounts to big large single pieces. Check out the carbon fiber snorkel poking out of the bodywork.
That snorkel goes to feed air to the rear brakes. With the engine being an inline 4-cylinder, a single exhaust dumps out the left side of the car. Back in the day, machining costs were much higher so the transaxle case looks to be cast whereas it’s not uncommon to see fully-machined ones on modern race cars. Some other little details are the aero profile to the rear rain light and also the quick release pin for the bodywork support rod. Oh, the carbon fiber bodywork above the exhaust pipe is protected with some heat shielding.
Sorry for the blurriness… but here’s a shot of the inboard mounted rear shocks. There’s also a small heat exchanger which I’m guessing would have been used to cool the tranny fluid.
The rear is pretty simple by modern prototype standards. What still remains the same today is the standard race car safety practices of using safety wire on bolts to prevent them from coming loose.
The modern gasoline turbocharger compressor housing can be a bit of a pain in the butt to cast. It has a mounting bracket for the electric wastegate actuator (at the bottom), a complex provision for the integrated electric compressor bypass valve (up top and you can see the port for the bypass leading back into the compressor inlet) , and VW/Audi likes to use this chamber on the compressor outlet (I think it’s for noise related purposes).
