What is ‘super clipping’ and how does it affect Formula 1 cars?

Super clipping is a technical phenomenon in the 2026 Formula 1 era where a car experiences a dramatic loss of straight-line speed once its available electrical energy is exhausted. This occurs because the new power units derive approximately 50% of their total power output from electrical components. When the battery energy is depleted, the “electric boost” disappears, leaving the internal combustion engine to propel the car alone and causing a sudden reduction in top speed.

What is Super Clipping?

Under the 2026 regulations, the hybrid power unit has undergone a massive shift, with approximately 50% of the total power output now coming from electrical components. Super clipping occurs when a car exhausts its available battery energy before reaching the end of a long straight.

When the battery runs dry, the electrical “boost” simply disappears. The effect is jarring: telemetry shows that cars begin to slow down during the second half of long straights even while the throttle pedal remains 100% open. Without the electrical half of its “heart,” the internal combustion engine is left alone to propel the car, leading to a sudden and dramatic reduction in top speed.

The Physical Impact: Losing 50 km/h in a Heartbeat

The data from the Australian Grand Prix qualifying session illustrates just how punishing this effect can be. In the high-speed run toward Turn 9, almost every car on the grid experienced a sharp downward curve in speed.

• George Russell (Mercedes): Reached 327 km/h but dropped to 278 km/h—a 49 km/h loss—before even hitting the brakes.
• Oscar Piastri (McLaren): Experienced the most extreme case, losing a staggering 57 km/h at the end of the straight.
• Charles Leclerc (Ferrari): Suffered a 44 km/h delta.

Notably, this phenomenon is most extreme during qualifying, where energy recovery is capped at 7MJ. In the race, where management is more balanced and the limit rises to 8MJ, the effect is less pronounced but remains a critical tactical hurdle.

The Tactical “Hoarding” of Energy

Because the electrical boost is finite, drivers can no longer simply stay “flat out” and expect consistent power. This has turned energy management into a game of tactical hoarding.

For example, during practice, Oscar Piastri was observed deferring maximum deployment even after exiting corners. He wouldn’t hit 100% power until just before the start/finish line, ensuring he started his flying lap with a completely full battery. This creates “highly variable recovery and deployment phases” throughout the field. A car might look competitive on one lap, only to become a “sitting duck” the next as it struggles to harvest energy, opening unexpected attack windows for following rivals.

The Software Advantage: Why All Engines are Not Equal

While the internal combustion engines are high-tech, the real battle in 2026 is being fought in software and energy deployment strategies.

Despite using the same Mercedes power unit, the works Mercedes team (the W17) was able to maintain much higher speeds and manage clipping more effectively than customer teams like McLaren and Williams. This indicates that the software managing how and when energy is harvested and deployed is now the primary differentiator in performance. Mercedes has found a “technical key” that allows them to maintain a consistent pace while others suffer from massive speed drops.

The Paradox of the 120 Overtakes

Super clipping is a major reason why Melbourne saw 120 overtakes compared to just 45 the previous year. When a leading car “clips” and loses 50 km/h on a straight, a following car with a “hoarded” boost can pass with ease.

However, experts caution that this creates a racing paradox: F1 is now more “alive” and visually spectacular, but the actual gaps between teams have widened. Mercedes finished the Australian GP with a 50-second lead over the fifth-place car, proving that while super clipping makes passing easier, it hasn’t necessarily made the championship any closer. As the season moves forward, the “Mario Kart” era will be defined by whoever can best manage their finite “boost” to avoid being caught in the super-clipping trap.
