Manufacturers currently involved in Formula One have agreed to come together and devise their own proposal addressing costs after the F1 Commission rejected the FIA's 'customer' alternative on Tuesday (24th November). Running up to Monday's deadline, three independent manufacturers – Ilmor, AER and Mecachrome – expressed their formal interest in supplying a low cost engine to run parallel to the existing ‘power unit’ rules. However the F1 Commission voted against the governing body's 'alternative engine' plans. Sport Bild reports that consideration has been given to keep the current regulations until 2017 and switching to an all-new engine formula for 2018. [It] said the new formula would “generate better PR, be louder and technically less complex”. Bild said: “In the end, everyone agreed to consider such a compromise. Apparently they have all realised that it is no longer about individual interests, but the very existence of formula one.” Following the proposal rejections the FIA will allow the manufacturers to collaborate on devising a proposal that will address the following: Guarantee the supply of Power Units to teams Lower the cost of Power Units to customer teams Simplify the technical specifications of the Power Units Improve the noise This news may well come as a blow to the likes of Red Bull Racing who following their recent engine woes were thought to be considering the low cost alternative while negotiations continue with manufacturers about a works supply in the future.
