Formula 1 will not be using standardised gearboxes in 2021 after the World Motor Sport Council voted against the proposal.
Earlier this year the FIA issued an invitation to companies to tender for standard gearboxes.
Motorsport’s governing body had hoped to introduce a single supplier for gearbox cassettes in 2021 in a bid to cut the costs of competing in Formula 1.
The proposal, though, has been voted down by the WMSC.
“The Council’s decision was based on consideration of both technical and financial information made available by teams and suppliers,” an FIA’s statement read.
“The technical data provided revealed that gearbox technology in Formula 1 has largely converged and that, as a result, there is little performance differentiation at present.
“It was also noted that, due to the complexity of the components, gearboxes remain a sensitive matter in terms of reliability, and this was factored into the evaluations of the FIA technical department.”
It continued: “Regarding the financial implications of the tender process, detailed financial data was requested from F1 competitors and a number of teams operating different business models supplied the FIA with relevant information.
“Analysis of this revealed that similar financial savings could be made by means other than the specification of a single supplier.
“These methods are being discussed with the Formula 1 teams and will be included in the regulatory package to be presented by the end of June.”
