The FIA recently confirmed that in-season engine development could go ahead after the federation admitted a loophole in the rules existed and could be exploited.
However contained within a technical directive issued to the teams before Christmas, the FIA made it clear that Honda was excluded because it is a new supplier.
“As the existing manufacturers were obliged to homologate their power units by 28 February 2014 it would seem fair and equitable to ask a new manufacturer to homologate their power unit before February 28, 2015,” said technical delegate Charlie Whiting in the note.
“We therefore consider this to be a requirement for a new power unit manufacturer.”
A McLaren-Honda spokesperson confirmed they were in discussion with the FIA about the ruling and admitted they were “annoyed and unhappy” with the decision, but refused to comment further whilst the talks are ongoing.
Ferrari and Renault have hailed the decision which will allow them to work on their engines throughout 2015. Mercedes meanwhile, which will also be allowed to develop their own engine, believe it will lead to unnecessary cost increases.
