Arturo Merzario
The team's assets were purchased by Arturo Merzario, and was merged with his own eponymous Merzario team, which had been having a similar lack of success with the A2 chassis. The Kauhsen WK was used as the basis for the Gian Paolo Dallara designed Merzario A4 car, but this did not improve from the performance of either of the cars, failing to qualify at the remaining World Championship rounds. The A4's only racing appearance was at the non-championship Dino Ferrari Grand Prix, finishing in 11th place. Merzario later left Formula One at the end of 1979, and moved to the Formula Two championship.
