The opening rounds of the season have exposed a knot of technical and safety questions around the starting procedure in modern Formula 1. What unfolded in Melbourne — a slow getaway from one car and a near-collision avoided by split-second reactions from another — has prompted senior figures, including Sergio Perez, to sound the alarm about the possibility of a far more serious incident. Teams are adjusting to a revised balance between combustion and electrical power, and that shift has transformed what previously felt like a routine sequence into a complex, high-stakes choreography.
Behind the headlines are concrete changes to the cars themselves: the reworked power unit package, the removal of the MGU-H and a much greater reliance on stored electrical energy have made the launch phase less predictable. Drivers must now hold raised engine speeds for a prolonged window to ensure the turbocharger builds pressure, or else risk tripping the anti-stall system that drastically reduces acceleration. That technical constraint has turned the first seconds off the line into a realm where timing, battery state and traffic all combine to create either a clean getaway or a dangerous mismatch of speeds.
Why the starts have become more complicated
The core mechanical shift is straightforward to describe but difficult to manage in practice: with the MGU-H removed, there is no longer a direct electrical assist to spin the turbo before lights out, so drivers must increase revs earlier and for longer. Teams instruct drivers to hold high rpm for at least ten seconds in some scenarios to spool the turbo, which raises the chance of either a perfect launch or an abrupt loss of drive if the timing is wrong. The term anti-stall refers to the system that intervenes when engine speed drops dangerously low, and in a grid context this intervention can produce a suddenly slowing car or a near-stop that following drivers may not anticipate.
Case study: the Melbourne near-miss and its variables
What unfolded on the opening lap
On the first race weekend under the new rules, one driver struggled to accelerate off the line due to a low battery and likely interaction with the new launch routine, while another driver behind reacted instantly to avoid contact. The delayed acceleration was hidden from a trailing car by the general shuffle of the pack, creating a situation where a normally routine closing speed became much higher than expected. Witnesses and participants described the episode as unusually sketchy, and the Alpine driver involved later reflected that the infusion of additional electrical power at certain moments can make a car that was creeping along suddenly surge, amplifying closing speeds.
Driver reactions and safety responses
Voices in the paddock have been direct. A senior driver warned that it is ‘‘only a matter of time’’ before a severe collision results from a problematic start under the new system, pointing to the many variables that can cause a car to get stuck in a low-power state. Teams and the FIA had already taken steps during pre-season to rehearse starts under these constraints, with supervised practice start runs during testing to help crews and drivers get accustomed to the new timing and battery-management demands. Nevertheless, the incident in Melbourne shows that on a race day, with traffic and limited visibility of cars further ahead, the risk profile is elevated.
What teams and officials are doing
Among the procedural changes introduced was a revised lights sequence: at some events drivers are now given an initial signal to begin raising engine speeds several seconds before the conventional five-red-light countdown, a practice designed to reduce late surges and the likelihood of anti-stall activations. Teams are also refining battery-management strategies and launch maps to limit extremes of speed differential, while engineers continue to search for a setup that reduces the chance of a car being caught out. Even so, those efforts have to contend with the fundamental physics of mixed energy deployment on short straights, where a car harvesting energy can meet another that is deploying it and create a rapid, and potentially hazardous, relative speed change.
In short, the new era of regulations has brought technical gains and fresh performance dynamics but also a sharper focus on the first few seconds after lights out. Drivers, engineers and race officials are all working to reduce the danger, yet the combination of revised power unit architecture, altered launch routines and crowded grids means that starts will remain one of the most scrutinized elements of an F1 weekend as the season progresses.
