Yamaha is aiming to 'accelerate the process' surrounding their V4 engine in an attempt to use it in the 2026 season.
Augusto Fernandez revealed that Yamaha still has a lot of work to do on their prototype V4 engine before using it in a race.
But he has admitted that all focus is on the new V4 engine to try and introduce it to the Yamaha M1 for the 2026 season.
"We need to accelerate the process because if we want to race with the V4 next year, we still need to do a lot of work," said Fernandez.
"It's not the full package yet. The engine is not the full one. Everything is just very early, the first chassis. But it's looking good. Everything looks very positive. But it's still not fast enough yet, which is what will decide for next year.
"So let’s see if in the next months, during this summer, we have some tests to try to accelerate the process and have the bike ready for the end of the season."
"The engine is not at its full potential," Fernandez added as he revealed he has not tested the V4 engine with full power yet.
"They don't give us all the power yet. But as I said, at some point we will need to see which one is faster in terms of lap time. That’s what will decide.
"But, there’s no negative. We just need better lap times. We're doing a good job and I think Yamaha is doing a good job. It will be a good bike.
"I feel very good with the V4. It's very different compared to our current bike. The potential looks like it is better, I can say.
"I’ve been working more and more on the V4 in recent tests, without forgetting our current M1. But we are at the end of the M1’s project, so everyone in Yamaha is fully focused on the V4 right now. We just need a bit more time."
