The Dallara 320 is one of the Dallara entries the open record knows by name, and by little else. That is not nothing: a name in the catalogue is where a car's story starts to be recoverable. The shape is credited to Luca Pignacca / Andrea Toso.
The background
The Dallara 320 is an open-wheel racing car developed by Italian manufacturer Dallara for use in the Euroformula Open Championship and Super Formula Lights. It was built as an upgraded version of the Dallara F317 chassis in which it replaces.
The engineering
the output is 240 hp. On the scales it comes to 575 kg including driver. That is roughly 417 horsepower per tonne: hypercar territory, where the limiting factor is the tyre, not the engine. The wheelbase is 2866 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
In the Dallara line-up the Dallara 320 has a clear place: it replaced the Dallara F317; it handed the line to the Dallara 324. Its Dallara stablemates include the Dallara F191 and the Dallara F2 2018.
