It has been revealed that Yamaha will debut their V4 MotoGP engine at the San Marino Grand Prix with Augusto Fernandez.

Yamaha has confirmed that its V4 MotoGP prototype will make its Grand Prix debut at next month’s San Marino Grand Prix at Misano.

Yamaha Racing Managing Director, Paolo Pavesio, revealed plans for Yamaha MotoGP Test Rider, Augusto Fernandez, to compete with the prototype engine during a wild-card entry for the event.

While a V4 wild-card had been expected this season, Misano was not the expected debut place for the engine, with Yamaha’s following home round at Motegi initially tipped.

"Finally, I have some important news to share," Pavesio revealed on Instagram.

"For Misano, we are targeting to see Augusto Fernandez racing for the very first time our new M1 prototype with a V4 engine.

"This is a concrete sign of our commitment to the future. While we continue to push with determination to get the best out of every race weekend.

"Thanks to everyone for continuing to support us and we are looking forward to seeing you [next time] in Barcelona."

Fabio Quartararo recently confirmed that he will test the new V4 engine for the first time during the Monday post-race test at Misano.

No lap times have been released for the bike, which Yamaha says will only replace the current Inline machine in 2026 if it proves fast enough.
