to retain Bell for the final two races in North America, terminating Galli's involvement with the company. In 1973, serious disagreements between the Pederzani brothers and Rossi and Yorke over the sporting and technical direction of the team generated a fracture that the two parties were never able to fully recompose. The Pederzanis were interested in hiring Clay Regazzoni, then a relatively new prospect, whereas Rossi and Yorke wanted the expert Chris Amon, who had been unable to agree terms with March Engineering for the season. Yorke and Rossi commissioned a new chassis from designer Gordon Fowell, while the Pederzanis hired Alan McCall to design a new car. McCall left before the project was fully developed, and the car was completed by Ron Tauranac, who was freelancing after selling Brabham at the end of 1972. After missing the early-season races due to the internal turmoil, Tecno finally debuted with the McCall/Tauranac car at the Belgian Grand Prix, where Amon finished sixth, achieving the team's first and only point. The car continued to show good promise in its second outing at the drivers circuit of Monaco, where Amon qualified 12th, in front of Jacky Ickx's Ferrari, and ran well in the upper midfield for 25 laps. At the British Grand Prix, Tecno found itself in the peculiar position of having two different cars available, with both the Fowell "Goral" car and the McCall/Touranac car in the garage. Amon qualified last. He managed to escape the multiple collision triggered by Jody Scheckter during the opening stages of the race that took out nine cars but had to retired with a broken fuel pump after six laps. Amon moved up to qualify 23rd for the Dutch Grand Prix but he had to retire again after 22 laps with the same technical problem. Having two different, underfunded and underdeveloped cars competing with scarce resources made the team's struggle untenable, and by the Austrian Grand Prix, the ongoing dispute between the Pederzanis and Yorke and Rossi resulted in a discontented Amon leaving the team to drive for Tyrrell. Despite having commissioned an eight-cylinder engine for the following year, the Pederzanis decided to shut down the Formula One program. Rossi took the Martini & Rossi sponsorship to Brabham in 1974, and eventually established the racing brand Martini Racing; Luciano and Gianfranco Pederzani retired from the sport, citing the toxic atmosphere that pervaded the team in 1973
