Ferrari Team Principal Frederic Vasseur has conceded the change in car design introduced with its Spanish Grand Prix upgrade was a "tough decision".
The Scuderia has ditched its unique scalloped sidepod design in favour of a Red Bull-esque shape at the Circuit de Barcelona-Catalunya as it aims to regain lost ground to Mercedes and Aston Martin in the early stages of the campaign.
Ferrari began the new F1 technical regulatory era as the fastest outfit but having been clawed back by Red Bull in the second half of last season before lacking pace this term, the decision has been made to explore a new developmental avenue.
"It is the opportunity to open a new door for future development," Vasseur told media, including RacingNews365.com.
"It is promising that we committed this way, let's see what the next weeks will bring to us. It was a tough decision.
"From this upgrade, we are expecting a step forward - not a huge one - and also to open some doors for the future.
"There are upgrades coming at the next couple of races, an opportunity to open a new direction but even from this upgrade, we expect a step forward."

Leclerc gets his chance
Carlos Sainz ran the upgraded look in first practice for the Spanish Grand Prix whilst Charles Leclerc continued with the old package.
But confirming parity would be restored for second practice, Vasseur said: "Charles will have the upgrade for this afternoon and we will do a back-to-back."
