Like several other Formula One drivers, Koinigg"s first racing car was a Mini Cooper. He purchased the car from Niki Lauda, which was also his first racing car. He raced in touring cars, Formula Vee and Formula Ford before a period in sports car racing.
After a good showing at the 1974 Canadian Grand Prix, Koinigg was beginning to establish himself as a good prospect for 1975.
But running near the back in the United States Grand Prix at Watkins Glen, Koinigg"s car suffered a suspension failure at turn 7, pitching it head-on into the Armco barrier. The speed at which Koinigg crashed was relatively minor, and he ought to have escaped the scene uninjured.
Unfortunately, as with a number of other circuits at that time, the Armco was insecurely installed and the bottom portion of it buckled as the vehicle struck lieutenant The car passed underneath the top portion, which remained intact, decapitating Koinigg and killing him instantly.
Koinigg"s accident was reminiscent of the death of Formula One driver François Cevert in the same event the previous year.
In qualifying for the 1973 United States of America Grand Prix, Cevert ran wide into the esses, crashing into and uprooting the barrier, killing him instantly. After Cevert"s death, a chicane called the "Scheckter Chicane" was placed at the esses to slow the cars down and help them avoid further serious accidents. However, it was removed ten years later in 1985, four years after Watkins Glen stopped holding the United States of America Grand Prix for Formula One.
