We have several "weapons" at hand that have been confirmed on dyno that would definitely make it better if introduced. However of course it's impossible to introduce all of them, so we have to decide final spec by assessing/evaluating which ones of these weapons would be most effective, which will make it in time, etc. Right now we are in the middle of verifying its reliability.
With the new spec whose combustion efficiency is improved, we can expect not only increased power but also better fuel consumption
Still, for instance if engine is improved and get power increase, then you can put more downforce for that amount, which then improves tyre life, which then makes strategy easier, so we should be able to go into positive spiral. Besides we were saving fuel quite a bit this time around too, but if power increases fuel consumption issue will be better as well. There is synergistic improvement cycle about it. So I don't consider that the actual gap is as big as it appears from outside. If one thing goes to positive direction, then the gap should be smaller and smaller, I reckon.
