Concerns are mounting around the complexity of the new Formula 1 regulations set for 2026, particularly regarding the race start procedure. Gabriel Bortoleto, an Audi rookie driver, pointed out the difficulties of managing the highly technical power units, especially when launching from a standstill on the grid.
With the focus on the power units’ energy demands, the start of the race has revealed a major challenge: only the internal combustion engine (ICE) is allowed to launch the car, while the electric motor cannot assist until speeds exceed 50 km/h. This creates problems for the turbocharger, which needs approximately ten seconds at high revolutions per minute (rpm) to reach its optimal operating level.
Turbo Lag Creates Risks at Race Starts
Bortoleto admitted even seasoned drivers find it difficult to monitor and execute the launch sequence correctly. Speaking from Bahrain, he said,
“Yeah, there’s this ten-second thing, then I lost the thread at five. The engine revs up, you shift in and out of gear, then you have to release the clutch – it’s chaos.” – Gabriel Bortoleto, Audi rookie
This complex procedure introduces risks that if a driver misjudges the timing—either by over-revving and spinning the wheels or stalling by dropping rpm—the result could be a poor start and pose safety hazards for cars following closely behind.
Concerns Extend to Drivers at the Rear of the Grid
Valtteri Bottas highlighted additional difficulties for drivers starting from the back due to grid penalties or qualifying positions. He voiced apprehension about whether there would be enough time to get the turbo up to speed before the race begins. Bottas explained,
“For example, in Melbourne I will have a five-place grid penalty, I will be towards the end of the grid,”
“Will I have enough time to rev the turbo? Now it takes about ten seconds. We have to solve this.” – Valtteri Bottas, driver
Teams Weigh Solutions as Ferrari Pushes Back
To address the issue, teams are exploring potential solutions such as implementing a mandatory delay between the last car taking its grid position and the start lights turning green. Another option under consideration is revising the current restriction on electric motor assistance during the launch phase.
Yet, Ferrari reportedly opposes regulatory changes. Sources within the paddock say Ferrari team principal Frederic Vasseur insists that all manufacturers were aware of the turbocharger’s operational requirements well in advance and should have engineered their systems accordingly.
Implications for 2026 Race Starts and Safety
The difficulty in managing the turbocharger lag at race starts threatens to create unpredictable, hazardous situations on the grid, especially for drivers at the back. Resolving these technical obstacles will be critical to ensure fair competition and safety when the Formula 1 season begins under the new 2026 regulations. How governing bodies and teams handle these challenges may influence the race start procedures and regulatory frameworks going forward.
