All composite material parts fitted directly on the engine (parts mentioned in Article 3) and the parts fitted in the cockpit or in the boot mentioned above (FR) must be made from fire‐
retardant material (seats and driver / codriver equipment / energy‐absorbing material: see FIA standarts). The external face of the part must have a V0 level of acceptance respecting
the "UL94" US standard (fire‐retardance capability).
Basically, this list precludes any meaningful use of MMC on these cars.
