With regard to the brake ducts themselves, Brown added that he has question marks "over the majority of the car", describing the initial FIA decision as "the tip of the iceberg".
In the FIA press conference, Brown described Racing Point's original line that the RP20 had been designed by photography as "BS", stating: "Around this whole copying, obviously they claimed that they had coped the car via photography.
"It’s clear from reading the document that is BS and therefore you have to question anything else around that car."
Following the conference, Brown added in the media pen: "That [the penalty] doesn't make any sense to the fans, let alone people in the paddock, and I think it needs to be looked at much more closely quickly.
"I don't think the penalty fits the crime in that last year they were seventh in the championship, now they're competing for third in the championship.
"That is worth tens of millions of dollars, so to get a €400,000 fine is insignificant in comparison to the benefits."
In a war of words between the teams, Racing Point team principal Otmar Szafnauer launched a furious counter to Brown's remarks.
“To Zak Brown it is BS because he’s not an engineer,” said Szafnauer. “He’s got no idea what he’s talking about. Zero!
“I’m surprised at how little he knows about the rules of Formula 1. It seems to me he knows more about historic racing than he does about Formula 1.”
