MONTE CARLO, Monaco -- Ferrari's rivals Red Bull and Mercedes are confident the FIA will clamp down on the Italian team if it is found to be running its energy recovery system outside the regulations.
There is no hard evidence that Ferrari has broken the rules this year, but there has been speculation that it has found a way to deliver more than the permitted 120kw from the power unit's MGU-K. The MGU-K is the part of the engine's hybrid system that recovers and deploys energy to the rear wheels, offering a maximum boost of 160bhp for roughly 33 seconds per lap.
