In the late 1960s Italian race organisers were offering additional money to anyone fielding an Italian car in F3 events. This led to a large number of manufacturers emerging from the woodwork, the most successful being Tecno. The legendary Brambilla bothers, Tino and Vittorio supported Birel in their efforts to create a local car, the resulting series of Brabham BT21 copies gave Vittorio some success in the final years of the 1-litre formula.
An almost direct clone of a contemporay Brabham, unfortunately for the Birel team it wasn’t as quick as the real thing and results were disappointing..
The Birel design was now beginning to move away, if only slightly, from its Brabham roots and The Brambilla brothers were now getting involved in the project. Ernesto Brambilla took a second place at Monza in May indicating the car was getting better.
The Birel now looked very like a Brabham BT21 and it was obviously going like one as Vittorio Brambilla scored several good results with it including wins at Vallelunga and Monza.
