Which they will be.
The works team, yeah but that has more to do with a fantastic chassis as well.
The Mercedes PU is most obviously superior in race pace. The internal combustion engines are chiefly limited by the fuel flow rate so the peak power between the three manufacturers should be within a few percent at most. The split turbo compressor and resultant improvement to MAF/intake temperatures pay dividends far over most other hardware changes to the engine itself. If Honda, Renault and Ferrari don't start off the 2015 a as on with split compressor/turbine designs than they are giving away free power.
The harvesting and recovery of energy is also the other key element to Mercedes's domination this year. Regulations cover the amount of energy that braking events (MGU-K) recover as well as how much can be deployed to the wheels. The difference has to be haveresdtef by the MGU-H. Mercedes does not pay a turbo lag penalty for the larger compressor they use as it can be spun up to speed electronically. At higer engine speeds, that larger turbo can and will produce more boost pressure than the engine can utilize because of the fuel flow limit. Rather than vent the excess power through a blow off valve, the MGU-H controls the boost (yes, the engine still does have a BOV for boost surges and the like). The more excess boost, the more harvested energy that can be deployed.
TL;DR all the teams should know where they are losing time and wasting fuel. Most of it isn't going to be made up from combustion engine mechanicals.
Food for thought; at Sochi, Massa couldn't pass Perez when Force India was having to save fuel. That particular event nullified a few variables. A car that was aerodynamically faster, with more raw power from the engine, was beaten over dozens of laps in a situation where tires, hybrid power and racing conditions were the same. Ergo, if Renault and Ferrari had equal hybrid power and cooling efficiency to Mercedes, a peak power deficit would mean that the teams with Renault and Ferrari engines would be far more competitive than they are.
Ferrari needs to admit to the fact they are dealing with a lot more than just a power gap to Mercedes right now.
