Helmet Cam reveals the extent of Carlos Sainz's struggles with purpoising in first practice ahead of the Australian Grand Prix.

Carlos Sainz says he is concerned about the long-term health effects the new Formula 1 cars could have on drivers, calling for a rethink on the philosophy as he fears "paying a price" with his career.

F1 has a completely new generation of cars for 2022 with a focus on improving wheel-to-wheel racing, and while that has so far materialised the cars are also heavier, stiff and have seen drivers suffer with violent bouncing.

Through the five races so far, many drivers have already spoken of the increased physical demands of the new cars, and Sainz went a step further ahead of this weekend's Spanish GP by saying they could have long-term effects.

"I think as drivers and Formula 1 we need to [consider] how much of a toll a driver should be paying for his back and his health in a Formula 1 career with this car's philosophy," said the Ferrari driver.

"I think we need to open the debate more than anything.

Ferrari's Carlos Sainz acknowledges that the porpoising this season has not been ideal and he hopes more 'driver-friendly' cars can be developed in the future.

"I think the regulations are great, they're doing exactly what was needed for racing.

"But do we need to run as stiff for necks and back as we are having to run lately with the car mass?

"For me it's more of a philosophy question that I put out there for Formula 1 and everyone to rethink about how much a driver needs to pay a price for his career with his health to combat this. I'm thinking more long term."

Lewis Hamilton continued to experience difficulties with porpoising in his Mercedes during P1 in Saudi Arabia.

Sainz admitted that the topic of health in a car was one that "drivers don't like talking about much, because we don't like sounding weak."

"I'm strong, I'm very fit and I consider myself one of the fittest drivers," explained the Spaniard. "I've never struggled in a Formula 1 race at all. But it's more long term and for the benefit of all of us."

Russell: New cars 'brutal' | 'People forget there is a human being inside'

Ferrari team-mate Charles Leclerc said he "didn't struggle as much" as Sainz but said he "definitely agrees" that the new cars shouldn't cause such physical effects. Pierre Gasly also said that it could be a long-term concern, although highlighted that his car has already improved with the porpoising through five races.

George Russell, meanwhile, called the new cars "brutal".

George Russell believes what Formula 1 drivers experience during porpoising is 'brutal' and that there need to be more conversations about their long-term health.

"I'd love to speak to my team and be able to share some of the data of the forces we're experiencing through the car," the Mercedes driver told Sky Sports F1.

"We're driving 200mph down the straight. The car is smashing against the floor.

"I think sometimes people forget there is a human being inside the car. We might have a helmet on, but it is brutal. A conversation needs to happen at some point."

Sainz wants to open debate about car philosophy

Sainz added in his written briefing: "I see this year I'm tighter everywhere. I'm already feeling it.

Sky F1's Karun Chandhok analyses the porpoising issue that has been troubling some drivers.

"I don't need expert advice to know that 10 years like this, it's going to be tough and you're going to need to work a lot in mobility, flexibility and I'm going to need to invest in health, body health.

"Maybe we should put it up out there to talk about and see what options do we have."

Simon Lazenby is joined by Damon Hill and Karun Chandhok to look ahead to the Spanish GP.

Sainz says he has yet to speak to other drivers about his concerns or the FIA, but hopes a debate can be opened.

"It will get to a point where if we decide to go in certain directions, the FIA needs to get involved for sure," he said, "Let's see in the future.

"It's still very early days, it was a thought I was having in the first five races when I've been suffering with porpoising, that I've never even brought up in a meeting yet.

"I was probably thinking out loud and it's something very young in my head and I probably need to speak to other drivers like George who are struggling with the same phenomenon, we need to sit together and see what we can offer or propose."
