Italian tyre manufacturer Pirelli, who came on board with TNZ on the eve of last year's America's Cup in Bermuda, will now co-sponsor Luna Rossa alongside luxury fashion house, Prada.
The multinational tyre company are the tyre supplier for Formula 1 and have been sponsoring sport since 1907.
Chairman of Luna Rossa Challenge, Patrizio Bertelli, described Pirelli as an "ideal partner".
"Pirelli is the ideal partner for this new America's Cup challenge. With over half a century's experience at the highest levels of high technology world sports, it will be an important asset at the heart of our project," Bertelli said.
