The creation of a new regional Formula 3 category in 2018 has added more fuel to the fire as the FIA aim to plug the gap between traditional F4 and F3. I see this new layer essentially as Formula 3.5 or Formula 3B.
So far 3 chassis manufacturers have signed up and built regional F3 spec cars for various regional championships. The new Asian F3 and W Series championships use the Tatuus T-318 with its 1.8 Turbo Alfa Romeo power plant. F3 Americas uses a (Crawford) Ligier JSF3 2.0 Honda. Meanwhile Mygale have produced a car in anticipation for future demand, powered by an Oreca 1.8 Turbo.
Last of all is the British F3 Tatuus 2.0 Cosworth pushing out 230bhp, although this essentially is a F4 car ‘on steroids’ and doesn’t not fit the new regulations. This was created to distance the championship from the established British F4 BTCC support series.
Formula 4 as a platform has succeeded globally, large grids and 4 chassis manufacturers catering for respective national markets. Crawford (Ligier) in the USA, Dome in Japan and Mygale /Tatuus sharing the spoils across 4 continents. If the F3 regional series can take off in similar fashion and emulate the national series of previous years then we could be on to a winner.
Despite the naming confusion the new motorsport ladder works on paper and seems to provide a progressive increase in power and downforce. As shown in the table below:
