Red Bull team boss Christian Horner has admitted his call for equalisation in Formula 1 is unlikely to become reality and is "probably not" right for the sport.
Horner suggested that governing body the FIA should consider using a mechanism within the regulations to close up the competitive order in F1, following a dominant one-two finish for Mercedes drivers Lewis Hamilton and Nico Rosberg in the Australian Grand Prix.
Red Bull's motorsport advisor Helmut Marko even suggested the Austrian firm could quit the sport entirely if nothing is done.
In an exclusive interview with AUTOSPORT, Horner admitted the calls for Mercedes to be pegged back were born of frustration at Red Bull-Renault's current lack of competitiveness.
"When you're in a scenario like we are, where you have very limited influence over the engine - we're effectively a customer - it's frustrating when your competitiveness is compromised and you don't have control over that," Horner told AUTOSPORT.
"Is that [equalisation] likely to happen? Of course it's not. Is it fundamentally right for it to happen? Probably not either.
"I was frustrated with the situation, but we also have a fairly unhealthy situation if you've got huge disparity between the different power units.
"The problem with where we're at at the moment is that the technology is pretty immature.
"The investment required by Renault to match Mercedes is enormous."
