The Bowin P3
was a 1968 project that gave Australia a fully professional monocoque racing car
. The P3 was designed for the Australian National Formula
and the Australian 1½ Litre Formula. After the capacity limit for Australian Formula 2
was increased from 1100cc to 1600cc at the beginning of 1969, the P3 found a new home in that class. The car was designed by John Joyce, founder of Bowin Cars
and assisted by Ray Parson, better known as a mechanic.
This was the only Bowin car type to come out of the Joyce-Parsons association. The project took just over 12 weeks to complete.
Only one Bowin P3 was car ever built. It was driven by Queensland racing driver
Glyn Scott, who fitted the car with a "spare" 1600 FVA Cosworth he bought from Piers Courage after the 1968 Tasman Series.
There were two major points about the Bowin Cars' construction: the chief aim of the project was to build a car that was economical enough for Australian racers to afford which was also easy to maintain – unlike most monocoques
. Equally important was the fact that almost every component of the car, with the exception of the engine and transmission, was entirely manufactured in Australia.
Joyce designed his own magnesium hub carries, suspension members, wheels, steering, and so on, and fabricated them in his own workshops or had them manufactured by Australian companies. For example, Commonwealth Aircraft Corporation cast the wheels and hub carriers.
