Ferrari, McLaren and Renault are the first teams to lodge their intention to appeal, and have done so at the end of a Friday of high political drama in F1, which started in the morning with the FIA confirming Racing Point had been deducted 15 points and fined €400,000 (£361,000) over their brake duct design.
Racing Point raised eyebrows at Barcelona testing when it unveiled a auto that looked remarkably similar to last year's championship-winning Mercedes.
Lewis Hamilton's all-conquering Mercedes team have been dragged into Formula One's latest "cheat" storm on the eve of the 70th Anniversary Grand Prix at Silverstone.
McLaren and Ferrari suspect Racing Point's breach of Formula One's regulations may go deeper than the stewards' decision issued on its brake ducts.
The team, owned by a consortium led by Stroll's father Lawrence, were weighing up whether to appeal.
"It is something that which again we have said in a letter to the FIA that we really argue the entire concept and entire process, we believe that the regulations are clear enough and we believe there may be a breach of regulation in that process". However, as of 2020, this was banned, so Racing Point has been tripped up by the rule change.
At pre-season testing in March (just before the season was postponed by the COVID-19 pandemic) onlookers spotted a curious resemblance between the 2020 Racing Point RP20, and the 2019 Mercedes AMG F1 W10 EQ Power+.
Reprimands were issued for the Hungarian and British Grands Prix.
The team will be lose 15 World Championship points- 7.5 points from each car- and take a fine of €400,000 for fielding Lance Stroll and Sergio Pérez's cars during the Styrian Grand Prix, and they have also been reprimanded for using the auto in both Hungary and Silverstone.
FIA head of single seaters Nikolas Tombazis said Racing Point had been transparent in what they had done but the copying had been taken too far and amendments to next year's sporting regulations are planned.
Having lodged complaints after every race so far this season, Renault has finally succeeded in taking down Racing Point.
"To Zak Brown it is BS because he's not an engineer", said Szafnauer. This is potentially the tip of the iceberg, the starting point of what has happened here.
"However, we now have to decide whether our punishment is one that we should appeal".
On Friday, Wolff, who has presided over Mercedes' unprecedented six consecutive drivers' and constructors' championships, defended his team's role in the saga which threatens to overshadow Hamilton's march towards a record-equalling seventh title.
"And therefore you have to question everything else around that auto".
The PA news agency understands they could be joined by a number of other teams, including Ferrari and McLaren. We invited the FIA in March to come and view everything that we did.
"We feel 100 per cent comfortable with our position", he said.
This weekend is likely to follow a similar pattern to last weekend, with Mercedes expected to dominate Saturday's qualifying session and Sunday's race.
