Super clipping is when a Formula 1 car loses speed on a straight despite the driver pressing the throttle fully.
1
Super clipping is when an F1 car visibly loses speed on a straight even at full throttle, because its hybrid battery has run out of stored electrical energy.
2
Modern F1 cars rely on both a petrol engine and an electrical boost system — when the battery is depleted, that boost disappears and the car slows noticeably.
3
Engineers carefully programme energy deployment lap by lap, and drivers use a technique called lifting and coasting to recharge the battery mid-lap and avoid running dry.
4
New F1 regulations from 2026 remove a key energy recovery device and increase the electrical system’s contribution to around 50% of total power, making super clipping a potentially bigger issue than ever before.

Understanding super clipping turns confusing speed differences between cars into a fascinating strategic battle over energy, playing out invisibly on every straight of every race.
Super clipping is when a Formula 1 car loses speed on a straight even though the driver is pressing the throttle fully. It happens because the car’s hybrid battery — which provides a significant electrical power boost on top of the petrol engine — has run out of stored energy. Without that boost, the car is noticeably slower until the battery recharges.
Have you ever watched an F1 race and spotted a car that looked oddly slow on a long straight — nothing visibly wrong, yet losing ground to its rivals?
That’s super clipping. And once you understand it, you’ll start seeing it everywhere.
It’s one of Formula 1’s most invisible battles. No crash, no mechanical failure, no driver mistake. But behind the scenes, engineers and drivers are fighting every lap to prevent it — because when it happens, it costs time, positions, and sometimes race wins.
What Exactly Is Super Clipping in F1?
Here’s the important part: modern F1 cars don’t run on petrol alone.
Every car uses a power unit — a combination of a petrol engine and an electrical system. The electrical system delivers a meaningful burst of extra power, particularly on long straights. That power comes from a battery, charged through energy recovery during braking.
Super clipping happens when the battery is completely empty at a moment when the driver still needs power. The throttle is pressed fully — but the electrical boost has gone. The car runs on petrol alone, and it’s measurably slower.
Think of it like a power drill with a battery assist. Fully charged, it cuts through anything quickly. Once the charge is exhausted, it still works — just noticeably slower. An F1 car mid-super-clip behaves exactly the same way.
How Does F1’s Hybrid System Work?
Every modern F1 car carries two electrical devices alongside its petrol engine.
The MGU-K (Motor Generator Unit – Kinetic) acts like a generator during braking — capturing energy that would otherwise be lost as heat, storing it in the battery, and releasing it as a power boost on straights.
The MGU-H (Motor Generator Unit – Heat) recovers energy from the turbocharger’s exhaust gases. Used from 2014 to 2025, it feeds additional charge into the electrical system each lap.
Both devices feed into the energy store — the car’s rechargeable battery. Once that battery is empty, the electrical boost stops. That’s when super clipping begins.
💡Did You Know?
Modern F1 cars produce over 1,000 horsepower in total. Around 160 of those come from the electrical system alone. Losing that contribution — even briefly — is like switching from a sports car to a family saloon mid-straight.
Why Do F1 Cars Lose Speed on a Straight Despite Full Throttle?
This is where it gets interesting — because it seems to contradict everything you’d expect.
The throttle only controls the petrol engine. The electrical system is managed separately, on a pre-programmed energy budget set before the race and adjusted lap by lap.
Teams decide precisely how much electrical energy to deploy, and where. Use most of it on one long straight for maximum speed there — and there may be very little left for the next. At that depleted point, the car clips: losing speed compared to a rival who still has charge available.
It’s like a cyclist sprinting uphill using everything they have, only to be overtaken on the following flat by a rider who paced themselves more carefully.
What’s the Difference Between Clipping and Super Clipping?
Clipping is any situation where electrical energy runs low or depleted, causing a speed reduction.
Super clipping is more extreme — the battery is completely exhausted, and the speed drop is notably large and sustained.
Both describe the same underlying problem. Super clipping is simply the dramatic version — the one viewers can most clearly spot on the speed readouts shown during broadcasts.
How Do Teams Manage Energy to Avoid Super Clipping?
Before each race, engineers calculate how much electrical energy the car will recover under braking each lap, and how much can safely be deployed on the straights. They build a deployment map — a lap-by-lap instruction set telling the car when to release energy and when to conserve it.
Deploy too much early, and the car super clips later. Conserve too much, and the car is needlessly slow — leaving time on the table.
Drivers contribute too, adjusting their style based on engineer instructions. The most common technique is lifting and coasting.
What Is Lifting and Coasting, and How Does It Help?
Lifting and coasting means releasing the throttle slightly earlier than normal before a braking zone — not to slow down sooner, but to give the MGU-K more time to capture and store energy.
Think of it like a ship captain cutting the engines early when approaching a harbour. The ship still arrives — passengers barely notice — but fuel is saved and control is maintained.
In F1, that extra recovery time means more charge in the battery, and more charge means the car can avoid super clipping at the next straight. What looks like a driver hesitating is actually deliberate and precise.
💡Did You Know?
During a safety car period, drivers can spend several laps lifting and coasting at multiple corners per lap. By the time racing resumes, the battery can be nearly fully recharged — giving drivers a significant speed advantage at the restart.
What Changes in 2026? The New F1 Power Unit Regulations
The 2026 season brings the most significant power unit changes since 2014 — and super clipping is central to the conversation.
What Are the 2026 F1 Power Unit Changes?
The MGU-H is being removed entirely. It was extraordinarily expensive to build, and its removal aims to cut costs and attract new manufacturers. In its place, the system relies on a larger MGU-K and a significantly bigger battery.
The balance of power also shifts dramatically. In 2025, electrical systems contribute roughly 20% of total car power. From 2026, that rises to approximately 50% — making the electrical element as important as the petrol engine.
Will Super Clipping Be Worse in 2026?
Potentially, and significantly. A 2025 car losing its electrical boost loses around 160 horsepower. A 2026 car in the same situation could lose far more — a much larger fraction of its total output.
The new regulations also require improved energy recovery to compensate, and the larger battery is designed to recharge more efficiently between straights. Whether this is enough to prevent dramatic super clipping events remains one of the key unknowns of the 2026 season.
What is confirmed: energy management in 2026 will be even more strategically critical than today.
💡Did You Know?
The MGU-H was so complex that only a handful of manufacturers worldwide could build one to the required standard. Mercedes spent years perfecting theirs — a key reason for their extended dominance in the hybrid era.

Frequently Asked Questions
What does super clipping mean in F1?
Super clipping is when an F1 car loses speed on a straight despite the driver pressing the throttle fully — because the hybrid battery has run out of stored electrical energy, removing the boost that supplements the petrol engine.
Why do F1 cars slow down on straights even at full throttle?
The throttle controls the petrol engine only. The electrical system — which adds significant extra power — runs on a separate, limited battery charge. When that charge is empty, the car loses its electrical boost and slows noticeably.
Is super clipping the same as lifting and coasting?
No — they’re opposites. Lifting and coasting is a deliberate recharging technique. Super clipping is what happens when the battery runs dry anyway. Drivers lift and coast to prevent super clipping at critical moments.
Does super clipping happen in every F1 race?
Not always obviously. Teams work hard to prevent it at key moments, but energy management affects every race. Some degree of speed variation caused by battery levels is present in almost every grand prix.
Will the 2026 regulations make super clipping more common?
Potentially, yes. With electrical power rising to ~50% of total output, losing that contribution will hit speed far harder than it does today. Improved recovery systems may compensate — but this remains one of the biggest technical unknowns of 2026.
What is the MGU-K and why does it matter?
The MGU-K generates electrical power during braking and releases it as extra speed on straights. When its stored energy is exhausted, super clipping occurs — making it the component most directly responsible for the phenomenon.
Does the driver control when the battery deploys?
Not directly. Deployment is pre-programmed by engineers and mapped to specific circuit sections. Drivers influence recovery through braking style and lifting and coasting, but the overall strategy is set by the team.
So What Now?
Super clipping is one of the hidden technical battles playing out on every straight of every race. Once you understand energy management, those speed readouts on-screen become a live window into a strategic chess match at 200 miles per hour. Keep exploring — every concept connects to something visible and meaningful in the race.
