Partnership with the ESTACA Formula Team
🤝The BONIONI team is proud to announce its partnership with the ESTACA Formula Team!
Since 1956, BONIONI has been developing its expertise in cold forming thanks to the dedication of its teams, innovation, and the passing down of know-how from one generation to the next.
It was therefore only natural that we chose to support the ESTACA Formula Team, a group of passionate students who design and develop a race car as part of the Formula Student challenge.
Beyond the technical aspects, this partnership is above all a human adventure rooted in values we share: collaboration, teamwork, perseverance, and the ability to tackle the most ambitious challenges together.
Because innovation thrives on the sharing of experience and tomorrow’s talents are already building tomorrow’s successes, we are delighted to contribute to this wonderful adventure and support these future engineers in their development.
We wish the entire ESTACA Formula Team great success in the challenges ahead! 🚗🏁 >>> More details and photos here: https://www.bonioni.com/en/partnership-with-the-estaca-formula-team/
