At that time the easiest way to enter F1 was to build a chassis ready to accept the Ford Cosworth DFV engine, which was competitive and readily available. Tecno tried it the hard way and set out to design both a new chassis and a new engine. Following a trend set by fellow Italians Mauro Forghieri and Carlo Chiti a flat 12 layout was chosen and like the Ferrari and Alfa Romeo units the Tecno was of a 180 degree V12 design. In the summer of 1971 the engine was tested on the bench and developed a decent 460 bhp at 11,000 rpm.
