The 2026 F1 race starts debate has been framed as a safety argument. It is not. It is a political fight wrapped in a technical problem, and Ferrari has been three steps ahead of the paddock the entire time. From the moment the MGU-H was written out of the regulations, Ferrari started engineering an advantage. When rivals tried to legislate that advantage away, Ferrari blocked them. When McLaren escalated it as a safety concern, Ferrari had Lewis Hamilton front and centre to tell the world it was nothing to worry about. Here is how every layer of this story actually fits together.

Key Points – 2026 F1 race starts
- The 2026 power unit removes the MGU-H, the component that eliminated turbo lag at race starts since 2014.
- Drivers must now rev stationary to over 13,000rpm for up to 10 seconds before launch. Articles C5.2.19 and C5.2.12 of the 2026 Technical Regulations block all MGU-K assistance until 50km/h.
- Ferrari designed a smaller, faster-spooling turbo around this exact problem during PU development.
- Ferrari blocked a Sporting Advisory Committee proposal last summer that would have revised the start light sequence.
- McLaren escalated the issue as a safety concern, the one mechanism that bypasses both the F1 Commission vote and Ferrari’s contractual veto.
- The FIA trialled a 5-second blue light pre-start window during the second Bahrain test and confirmed no major rule changes before Melbourne.
- Ferrari’s turbo architecture advantage is reduced but not eliminated heading into Australia.
Why 2026 Race Starts Are So Different
To understand the politics, you first need to understand the engineering. The MGU-H was the motor generator unit attached directly to the turbocharger shaft. From 2014 through to the end of 2025, it could actively spin the turbo using electrical energy, which meant it eliminated turbo lag at exactly the moment drivers needed it most: the standing start. That component is gone in 2026, removed on cost and complexity grounds. In its place, the MGU-K has been uprated from 120kW to 350kW, roughly 50 per cent of total power output. But the MGU-K is not connected to the turbocharger. It cannot pre-spool anything.
Without an electrical motor driving the turbo, the only way to get it spinning is the old-fashioned way: exhaust gas flow, which means high engine rpm. Data from the Bahrain pre-season test recorded peaks of over 13,000rpm during practice starts, values the previous generation of power units only hit at maximum race effort on circuit, never sitting stationary on a grid. Drivers must now hold that state for up to 10 seconds waiting for the turbo to reach an efficient operating speed. Hamilton was filmed at Ferrari revving for a full 22 seconds during one practice start, and it went viral for a reason: it looks and sounds nothing like an F1 start has for over a decade.
“The 10-second thing, and then after five seconds I already lost the count. Engines revving up, gear in and out, you need to release the clutch. It is quite a mess. It was much easier last year.”
Gabriel Bortoleto, Audi
There is a second layer that makes this worse, and it is written into two separate articles of the 2026 Technical Regulations. Article C5.2.19 states that while the car is stationary on the grid, the MGU-K torque may only be negative, meaning it can only charge the battery. It cannot assist the engine at all. Then Article C5.2.12 states the MGU-K cannot be used to propel the car during a standing start until 50km/h. Two rules stacking on top of each other: no help while stationary, no help at all until you are already rolling. Get the revs wrong, release the clutch at the wrong point, catch the turbo out of its operating window: there is nothing to recover with. And even once you hit 50km/h, Lando Norris put it plainly: use the MGU-K early to rescue a bad start and you have burned battery you need for the rest of the lap. Then at that 50km/h threshold, 350kW of electric torque dumps in on top of whatever the combustion engine is already doing. That is another variable in an already complicated sequence.
For drivers at the back of the grid there is an additional problem entirely. They pull into position later than those at the front. By the time they are stationary and ready to begin the spool procedure, the light sequence may already have started. They do not have 10 seconds. Bottas flagged this specifically ahead of Melbourne, where he will serve a grid penalty carried over into the opening round that places him at the rear. The timing issue is not hypothetical.
“My only concern is: if you are at the back of the grid for the race start, once you start holding your revs, the lights will already start going and you will not have enough time to get the turbo spinning before they go out.”
Valtteri Bottas, Cadillac
Ferrari Saw This Coming
Ferrari raised the start procedure concern with the FIA during 2025 and was told the procedures would remain unchanged. Rather than continuing to push for regulatory intervention, Ferrari responded with engineering. Charles Leclerc confirmed during testing that starts were a factor in how Ferrari approached its 2026 power unit design. George Russell, watching Ferrari-powered cars consistently launch cleaner than Mercedes customers, concluded the most logical explanation was a smaller turbo. Smaller turbos spin faster, reach their operating window quicker, and are therefore easier to spool within the existing procedure. Russell has no inside knowledge of Ferrari’s architecture. He is making an educated observation based on what he is seeing, and the gear ratios Ferrari drivers are selecting off the line.
That design choice required Ferrari to accept trade-offs elsewhere. A smaller turbo produces different performance characteristics at higher engine speeds. Ferrari made that compromise willingly because they understood exactly what the start regulations would demand, and they built to suit those regulations as written. That is not gamesmanship. That is engineering.
How Ferrari Blocked the Fix
Last summer, the FIA’s Sporting Advisory Committee put forward a proposal to revise the start light sequence, giving drivers more time between grid formation and lights-out. Ferrari team principal Fred Vasseur blocked it. His argument was principled: the turbo lag issue was well understood during the PU design phase, every manufacturer had access to the same regulations and the same technical knowledge, and Ferrari had made choices that worked within those regulations as written. Changing the procedure to accommodate teams that made different choices would penalise Ferrari for doing the engineering work correctly.
That argument holds. It is the same logic that governs every regulation cycle in Formula 1: if the rules allow something and you exploit it, you are entitled to defend that. Vasseur was not protecting an illegal advantage. He was protecting a legitimate competitive edge that his team had earned through better design decisions.
McLaren’s Safety Escalation
By the time of the first Bahrain pre-season test, the start disparity between Ferrari-powered cars and Mercedes customers was visible enough to provoke a public response. McLaren team principal Andrea Stella escalated three concerns to the FIA and F1 Commission: race starts, closing speeds from the active aero system, and the straight mode being available at the start of a race. On starts specifically, Stella framed the issue as a safety concern.
That framing matters enormously. A normal regulatory proposal goes through the F1 Commission, requires a supermajority, and is subject to Ferrari’s contractual veto for rule changes that affect the DNA of the competition. A safety technical directive bypasses all of that. The FIA race director can mandate changes on safety grounds without a vote, without a threshold, and without any veto mechanism applying. It is the one constitutional door in the governance structure that Ferrari cannot bolt from the inside.
The precedent for this was set in 2022, when the FIA invoked safety to push through porpoising floor changes despite significant team opposition led by Ferrari. Ferrari did not attempt to use its veto because the safety framing made it non-applicable. The veto protects the sporting regulations. It does not protect against safety interventions. McLaren’s team understood that precedent. Whether the safety concern is genuine or tactical is almost certainly both things simultaneously, and that distinction may matter less than people assume.
Verstappen, Hamilton and the Question of Neutrality
At the press conference midway through the second Bahrain test, the drivers were asked about safety at the starts. The two most prominent voices dismissing the concern were Lewis Hamilton and Max Verstappen.
“It is definitely not dangerous. I think we should probably take that connotation away from it. It is just a different procedure, just a longer procedure than it has been in the past.”
Lewis Hamilton, Ferrari
Both quotes have been widely reported as drivers simply reassuring the paddock. That reading requires ignoring the context. Hamilton is now a Ferrari driver. Ferrari has a competitive advantage from the current start procedure. Ferrari’s team principal blocked the rule change that would have reduced that advantage. Hamilton dismissing the safety framing is entirely consistent with Ferrari’s position, and that does not make his assessment wrong, it just means it cannot be read as neutral.
Verstappen’s situation is different but equally relevant. Red Bull run their own power unit in partnership with Ford. They are not a Mercedes customer. They do not share the same vulnerability to the start disparity that McLaren, Williams, Alpine, and the Mercedes works team face. Verstappen poking fun at the concern is characteristically Verstappen, but it is also the voice of someone whose team is not on the losing side of this particular technical argument.
“You should start from the pit lane if you feel unsafe. You will catch up by Turn 4 anyway to the back of the pack.”
Max Verstappen, Red Bull
Bottas offered the most balanced perspective in the same press conference: not dangerous in principle, but the back-of-grid timing issue is real and needs addressing. That caveat came from the driver most directly exposed to it.
What the FIA Has Actually Done
Following the F1 Commission meeting during the second Bahrain test, the FIA confirmed it would trial amendments to the start procedure. In the final practice start sessions of the test, a 5-second blue light window was introduced before the standard red light sequence begins. The purpose is to give all drivers, including those at the back of the grid, sufficient time to complete the spool procedure before the official sequence starts.
On the wider issue of starts, the FIA’s formal position was direct: no immediate major regulatory changes are required before Melbourne. The reasoning given was that evidence is still immature and premature change carries the risk of increased instability ahead of the first race. Further reviews will follow once more data is available from the opening race weekends.
The straight mode ban for race starts was agreed across the paddock during testing and is pending formal ratification. That removes the secondary concern Piastri flagged about 22 cars launching with reduced downforce, but it does not address the underlying turbo spool disparity.
Going Into Melbourne
The 5-second blue light addition helps the back-of-grid timing problem. It does not change Ferrari’s turbo architecture. Their power unit still reaches the launch window faster than Mercedes customers. The advantage has been reduced at the margins, not structurally addressed. Andrea Stella said as much after the second test concluded: the FIA changes are positive, but the disparity in start performance across the grid has not been overcome.
With 2026’s active aero system making overtaking harder than the DRS era it replaces, track position off the start line carries more value than it has done in years. A driver who gains two positions at Turn 1 in Melbourne may be holding them until lap 40. That is the competitive significance sitting underneath all the governance language.
Coffee Corner Take
The framing of this story as Ferrari doing something questionable is wrong. Ferrari raised the problem with the FIA a year ago and got told nothing would change. So they built a power unit that worked with the rules as written, then defended those rules when a proposal came to change them. That is not cynical. That is what good teams do.
McLaren’s escalation is also legitimate. The safety framing is convenient, obviously, but it is not fabricated. A grid of 22 cars launching with variable turbo response, some stalling, some catching anti-stall, is not a stable situation at 300 km/h closing speeds. The 2022 porpoising intervention happened because the safety argument was genuinely valid, not because someone needed a political tool. Both things can be true: the safety concern is real, and McLaren chose the one mechanism they knew Ferrari could not veto.
What is worth noting is that Ferrari sits on multiple layers of protection: customer team votes, the contractual veto, and the principle that regulations should mean what they say. McLaren found the one key that opens a door Ferrari cannot bolt. The FIA holds that key, not the teams, and the FIA used it, partially. Melbourne will tell us how much of the advantage actually remains.
Hamilton says it is not dangerous while driving for Ferrari. He would. Verstappen says start from the pit lane while running a Red Bull power unit, which makes you wonder if they have a fix up their sleeve. Neutrality is a luxury in Formula 1. Read the quotes knowing who they work for, because they will always play the line that protects any advantage in a sport that is literally decided by hundredths of a second.
