Three F1 power unit manufacturers have blocked FIA proposals for 2027 power unit changes, according to German media, putting Max Verstappen‘s future in doubt.

Audi, Honda, and Ferrari have emerged as the primary obstacles to proposed changes, which aim to shift the balance between the internal combustion engine and the electric motor to a 60/40 split, which would reduce the electric restrictions on drivers.

However, according to Auto Motor und Sport, several concerns remain among the power unit manufacturers. Audi and Honda are especially worried about the financial implications and the extra investments needed to adapt their cars.

Meanwhile, Ferrari is also opposed to the change but believes that part of its gap with Mercedes could be bridged through the Additional Development and Upgrade Opportunities (ADUO) programme.

The debate has been ongoing for weeks, and Verstappen has hinted that his future could depend on these changes.

The four-time F1 world champion has constantly reiterated over the past few months that the new cars are ‘not fun’ to drive, and has threatened to quit the sport on more than one occasion.

At the Canadian Grand Prix last time out, the 28-year-old also said that driving in the sport beyond the end of this season is ‘not doable’ unless changes are made to the rules.

What changes have already been implemented, and what is to come?

Since the Miami Grand Prix weekend, minor adjustments have been introduced that help restore some of the old racing feel for the drivers.

While more extensive changes are planned for next season, nothing has been finalised yet – even though support for the proposals is growing.

To implement these changes for next year, a supermajority is required, meaning four out of the six engine suppliers must vote in favour.

While both Red Bull and Mercedes are open to the adjustments, Cadillac – although not producing engines at the moment but planning to do so in the future – is expected to side with Ferrari. For now, reaching a consensus appears to be a distant prospect.

A championship-winning driver has been testing McLaren F1 machinery recently, coinciding with reports Red Bull are eyeing up driver Oscar Piastri.

Max Verstappen is the champagne cork that, once released, will open up the F1 driver market, with rumours suggesting he could either leave Red Bull or the sport entirely.

Red Bull are said to be taking the chance of a Verstappen exit seriously, and have lined up Piastri as a possible replacement should he decide to leave.

On the intensifying rumours, Oscar Piastri told Sky Sports: “There’s obviously not been any discussions or anything but it’s flattering, yes. There’s not really much more than that, really.

“Hopefully it proves my stock as a driver, which is a nice thing, but I’m very happy with where I am.

“I’ve got a lot of confidence in this team that we’re going to be able to win races and hopefully championships in the future, so I’m very happy where I am.”

“I’ve got a good relationship with McLaren, so why change?”

Leonardo Fornaroli tests with McLaren

Elsewhere, McLaren have been busy with their Testing of Previous Cars (TPC) in Austin at the F1 track the Circuit of the Americas (COTA).

Here McLaren reserve driver and 2025 Formula 2 champion Leonardo Fornaroli drove the 2023 MCL60 around the track in a two-day test as part of his progression in their Driver Development Programme.

In his third TPC test, he completed 77 laps (425km) across two days of running on Wednesday and Thursday, and his run plan consisted of a mix of long and short runs, grid start procedures, and formation lap practice.

Fornaroli said after the test: “It’s always amazing to drive an F1 car. I’m grateful to McLaren for giving me another opportunity to get behind the wheel of the MCL60.

“I’m getting more comfortable with the car and also the team. The run plan was a step up from my last test in Silverstone. We got to do some practice starts, which continued to give me a better understanding of what it takes to drive an F1 car in a session. Everyone in the DDP programme continues to support and push me with these tests as I continue my development.

“This was my first time driving around COTA. I really enjoyed it, and I am already looking forward to my next opportunity in an F1 car. Until then, I’ll be supporting the F1 team in the simulator for the Monaco GP.”

Mercedes star George Russell is facing the very real prospect of a humiliating demotion in his own team according to Sky Sports F1 expert Ralf Schumacher.

The 28-year-old went into the 2026 season as favourite with the oddsmakers to claim his first championship after Mercedes were expected to dominate in the new regulations era.

Everything started perfectly in Melbourne as Russell won the season-opening Australian Grand Prix, but since that Sunday in early March things have gone south in a big way.

Russell title bid nosedives<;h2>

The 19-year-old Antonelli has won each of the four races since Australia, and showed he has steel as well as skill during a fiery battle with Russell during the sprint race in Canada recently.

Russell hit a new low a day later in the Canadian Grand Prix when a mechanical failure saw him DNF after 29 laps. He came away from Montreal pointless, exasperated and now 43 points behind Antonelli in the standings.

According to former F1 star and now Sky Germany pundit Schumacher, Russell now risks being relegated to the role of second driver at Mercedes. The pressure is really on as the title race moves on to the Monaco Grand Prix this weekend.

Schumacher fears for Russell Mercedes role

Schumacher believes that the experienced Brit must quickly close the gap on Antonelli, or the team may be forced to intervene and pin their title hopes firmly on the young Italian.

Speaking to the Backstage Boxengasse podcast, he claimed: “Things aren’t going to get easier for Russell from here. He needs to start closing that gap immediately, investing more in himself and on track.”

Hamilton vs Rosberg 2.0 incoming

The battle between Russell and Antonelli in Montreal led Mercedes team principal Toto Wolff to intervene on team radio, and it brought back memories of the brutal battles between former Silver Arrows team-mates Lewis Hamilton and Nico Rosberg.

Schumacher continued: “From where I stand, Barcelona [2016] isn’t that far off. Let’s see if history repeats itself like it did with Nico Rosberg and Lewis Hamilton – I suspect these two might eventually clash on the track.”

Will Mercedes demote Russell?

While Mercedes publicly deny having a designated first or second driver, Schumacher believes things might change if their title rivals start to cut the gap.

“If Kimi can maintain his pace for the next three or four races and stay ahead of George, will the team eventually make a decision? ‘Okay, we have our lead driver, let’s finish the season this way?’

“There’s immense potential for this to escalate. One thing is certain: George Russell is extremely frustrated. You could see it when he claimed pole position – he was overjoyed, clearly relishing every moment.”
