Lewis Hamilton has said the regulation change for the 2026 Formula 1 season is the biggest he has ever experienced in his 20-year career.
The rules have been redefined for the upcoming campaign, with sweeping changes to the cars and engines -- with the hope of more exciting, more competitive wheel-to-wheel racing.
Ferrari was the latest to reveal its new car on Friday ahead of the start of preseason testing -- behind closed doors in Barcelona -- on Friday and Hamilton spoke about the regulations, and how he has been involved with the Italian team.
"The 2026 season represents a huge challenge for everyone, probably the biggest regulation change I have experienced in my career," Hamilton said.
"When a new era begins everything revolves around development, growth as a team, and moving forward in the same direction.

"As a driver, being involved from the very start in the development of such a different car has been a particularly fascinating challenge, working closely with the engineers to help define a clear direction for the it. It will be an extremely important year from a technical perspective, with the driver playing a central role in energy management, understanding the new systems and contributing to the car's development.
"It is a challenge we face together as a team, supported by the extraordinary passion of Ferrari's tifosi, which means so much to all of us."
Hamilton finished a disappointing sixth in the championship last year, while Ferrari were only fourth in the constructors' standings. Hamilton's teammate Charles Leclerc outqualified the seven-time champion 19 times in 24 appearances.
He will have a new race engineer for the forthcoming season -- which begins in Australia on March 8 -- after he parted company with Riccardo Adami.
Ferrari team principal Fred Vasseur accepts bringing everything together -- in the car as well as off the track -- will be a "challenge" and represents a "full reset" for the drivers, but is one they will all tackle full throttle together.
"Performance of every single area is key but, at the end of the day, the biggest challenge will include the integration of all the systems together -- including the drivers, honestly, it will be a full reset for them on their approach," Vasseur said at a virtual press conference on Friday afternoon.
"It means that they will have to change completely the way that they have to approach the weekend, develop during the weekend, the way of even driving will be probably a bit different.
"It means that this also for them will be a challenge and part of our job will be to give them the good tools to be at their maximum."
Vasseur added: "It is true that we are all starting from scratch, we are all discovering the challenges.
"I think this is a good feeling, I would say, because that is our job, our DNA to challenge this kind of situation, and drivers are part of the equation. It is a very interesting challenge for us and for the others."
