The majority of teams oppose the new technical regulations for 2021 being proposed by Formula 1, BBC Sport can reveal.
The questionnaire asked about 10 questions, including whether teams preferred to press ahead with the proposed 2021 rules or stick with the existing regulations.
Since then, there has been a meeting of the technical working group of the FIA and teams’ leading engineers, at which Alfa Romeo and McLaren were among those to propose changes to the 2021 rules as they stand.
Ferrari, Mercedes and Red Bull presented their own proposal for 2021 to the FIA and F1 on Thursday.
