Valtteri Bottas believes Williams' improved showing without the Coanda exhaust in Abu Dhabi is a positive sign for the future.
During Friday's practice at the Yas Marina circuit, Williams opted not to run their Coanda exhaust instead putting a non exhaust-blowing set-up on the FW24.
Such was the improvement that the team continued like that for the remainder of the weekend.
And as exhaust-blowing won't be possible next season, Bottas reckons that was a good step for the Williams team.
"It is better to drive, it is more predictable and now the car and the aerodynamics are doing more or less what they should do," the Finn told Autosport.
"It feels better and a good thing is that in next year's car, there is not going to be Coanda.
"Other teams have been ahead of us in developing the Coanda effect and I am pretty sure they are gaining more [there] than we did.
"Next year, the aerodynamics of the car need to work without that and it's going to be a good thing for us and hopefully a chance to catch up with the others."
