Formula 1 chief technical officer Pat Symonds has conceded the aerodynami𓃲c rule changes for the 2019ꦐ season failed to have meaningful change, adding that with hindsight he “wouldn’t have done them”.

F1 t𓆏weaked its aerodynamic rules for the 2019 season in a bid to help cars follow each other more closely, only for the drivers to report little if any change once they hit the track.

Speaking at Autosport International on Thur💝sday, Symonds admitted the level of change brought about by the tweaks was “not as much as I would have hoped for”, but said they were still useful ahead of the more widespread changes for 2021.

“They were done in a bi✤t of a hurry, and with the benefit of hindsight, I wouldn’t hღave done them, but that’s with the benefit of hindsight,” Symonds said.

“In terms of what they did to the wake of the🎐 car, relative to what we’ve done in 2021, it’s been useful. And꧂ in fact, we have never run the exact configuration that the rules came up with.

“What we’d done is a lot of research by that time. We’re now talking late ’18, mid ’18. We’d done a fair bit of work, and we were starting to underst✃and the critical areas, but we hadn’t run the configuration that we actually had to get some rules out for.

“So I think we could have done that whole exercise a little bit better, and I d𒁏on’t regard that in any way to be a precedent for what we’ve done in 2021.”

F1 has taken a more root-and-branch approach to its change of the technical regulations for the 2021 season, with the final set of rul꧙es being published at the end of October.
