This is a fictional Formula 1 car, "designed" by German Motorsport-Magazine "Sport-Auto" in 1976. They developed the Tyrrell 6-wheeler to this 8-wheeler (aerodynamic advantages). The motor is in front of the driver, between the axles. The idea was, to rescue the driver completly with his seat. At that time they hoped, that a German work will participate in the World-Championship (you can read Porsche on the drawing).
