Formula 3 is one of the last remaining series outside of Formula 1 that has an open chassis tender. Meaning teams are able to choose and work with which ever chassis supplier they wish.
Hitech GP rely on the know-how of experienced Italian chassis manufacturer Tatuus.
The chassis used have been homologated for the 2018 Formula 3 Asian Championship, featuring a Tatuus F.3 T-318 monocoque carbon composite, and FIA homologated Tatuus Halo.
The chassis used are the ones of the 2012 specification that have been homologated for Formula 3 up to and including 2019. With their stepped under-floor, a crash box at both the front and the rear as well as two roll-structures, the vehicles are extremely safe. In addition, they have had to pass the strict FIA crash tests for homologation.
Still, the drivers should not overdo it: Even in the case of a crash resulting in a massively damaged chassis, replacing the chassis during the course of an event is prohibited. The minimum weight of the vehicle – including the driver in full racing gear and all the fluids apart from the fuel – amounts to 565 kilograms. The car width including the tyres must not exceed 1,850 mm and the minimum wheel base amounts to 2,000 mm.
There are 3 options of downforce levels that can be run during the season; Low downforce, medium and high. This is obtained by changing the rear wing main planes, removing or adding front wing flaps or altering positioning and length of the rear floor diffuser trim.
