The winning entry has been chosen in the competition to design a helmet for Hispania Racing driver Bruno Senna to wear as a tribute to his late uncle at a grand prix later this year.

Three-time champion Ayrton Senna would have turned 50 this year, and the competition clearly sparked the imagination as over 500 entries were received from around the world but, after a tight race to the very end of the public vote, Rai Caldato from Campinas in Brazil, emerged as the winner.

Of the five finalists shortlisted by judges, including Bruno, other members of the Senna family and the designers of Ayrton's helmets, Rai collected 8892 votes, but had to overhaul another Brazilian, Bruno Mantovani, who was leading until the final stages of voting but eventually finished second on 8093 votes.

Caldato can now look forward to seeing Senna wear his design; an announcement on when and where that will be is expected soon. The winner will also receive a replica of the helmet, signed by Senna, together with a signed photo of the driver proudly wearing the design. The special race helmet itself will then be auctioned, with all money raised to be donated to the Ayrton Senna Foundation.
