Naoki Tokunaga admits 2014 will be a fuel economy contest.
"...Because you have to save fuel, it means there will be a difference between average power use through races and the maximum power available.
"But that then means if you need it, the maximum power is always available. So if you want to try to use it to get past another car, then you can.
"And afterwards you will then have to make up for the extra fuel used. It will mean
more diverse strategies...."
(emphasis added, the new code for "fuel economy contest")
He continues to equivocate this to the current strategery of starting the race with the lightest possible fuel load:
"...We don't want to leave any fuel in the tank when the race is finished, so we have to manage fuel consumption now. It will be the same, and nothing has changed...."
Except that in 2013, starting fuel load is calculated to allow the driver to drive as fast as his tyres and his talents allow, unless and until the race takes an unexpected turn. For 2014, OTOH, a driver will only ever be lapping as fast as his race engineer tells him his remaining fuel load allows, from when the lights go out until he returns to the paddock. Because radical G-load changes prevent fuel ever settling to a 'normal' level in the tank(s), no fuel gauge sensor will work in an F1 car, so remaining fuel is calculated by engineers comparing trends in damper loads against starting fuel load and historic fuel consumption rates. Which is why the driver must rely on his race engineer to apprise him how close he is on fuel. In 2013, remaining fuel only becomes an issue when the race plays our unexpectedly. In 2014, it will be the mainstay of race strategery.
This might be Tokunaga's notion of nothing changing, but it's my notion of sea change.
