Christian Horner says it is 'crucial' the FIA and FOM get the go ahead to introduce an independent engine supply in order to stop teams leaving the sport or struggle to secure a supply.

Red Bull Racing's future in F1 remains unknown at the moment as it struggles to source an engine supply having split with Renault and been rejected by Mercedes and Ferrari for a supply. A mooted rescue supply from Honda is currently being blocked by McLaren.

Last week the FIA and FOM announced it is pushing on with a proposal for an independent customer engine, primarily as a means of cutting costs for smaller teams. However, with no regulation in place to force manufacturers to offer an engine if a team requires a supply either, the customer engine is also potentially beneficial for a team like Red Bull.

With this in mind, Horner says he is very much in favour of the engine - which is set to run a different specification to the current V6 Hybrid power units -, saying it is 'crucial' for F1, particularly when it comes to manufacturers decided whether or not to supply.

"I think the FIA has two problems, one is the cost of supply and one is the willingness to supply. Within the current regulations you can't force manufacturers to supply. So, therefore there has to be an alternative but that alternative also needs to be competitive."

"I think it's crucial, as I think we're demonstrating quite clearly. There is no regulation that dictates that engine suppliers have to supply and let alone at a competitive price. I think an independent engine for the future of Formula One is a no-brainer because if you can't get engines elsewhere; then you can't race.

"For Formula One, it's important to have a competitive, economical engine and if it can't be the current engine, then it needs to be another engine."

Though the proposal still needs to go through the relevant stages in order to be passed, Horner believes there will be enough support from the smaller teams to ensure it goes ahead for a 2017 introduction.

"I'm sure if there is enough willingness and there are enough teams that are struggling financially. If you can take 20 million out of your engine chassis budget, it's a no brainer"
