While the two companies have been working in partnership for decades, Shell has announced that it is active from the concept phase of this year's car to ensure Ferrari has the most compact chassis it can.
All the benefits that Ferrari can achieve A smaller fuel tank and better rear-end packaging can provide immediate benefits in terms of weight and aerodynamics.
Benoit Poulet, Shell's F1 fuel development manager, told Motorsport.com, "The same fuel flow is the framework and many of our compromises have been similar.
"But integration with the chassis has increased over the past year, and we've incorporated more and more chassis aspects and chassis compromises to achieve that extra power for the suspension vehicle as a complete design.
Ferrari and Shell's efforts to deliver a more compact chassis are set against an increase in the 201
"We have built this compromise between engine performance and engine engine efficiency," he said. "Besides, six months ago, we had this talk on the chassis side about the chassis design.
"There will be some races where [the new fuel allowance] could bring us more, but the question is all Now is it time, do we really need that?
"We worked very hard on a really efficient engine with Ferrari. Based on the same regulation with the power supply unit, we could now really predict the performance of many fuels.
"And if they have a similar performance, we'd prefer higher density fuel, since everything like [in the rules]] is based on kilograms, which means less volume, so you can make your car thinner."
Poulet is skeptical that the new fuel addition will lead to a completely different approach than teams.
"That was clearly the case. We've seen that we have the extra 5kg that gives more freedom," he explained, "but really important in the development is the fuel flow, and this value has not been changed.
a common technical goal, namely efficiency is the key: we have worked massively to bring together the most efficient fuel and the most efficient engine
"The leap to 110 kg is thus an additional freedom from the operational aspects of the car. "
