First and foremost for the drivers and engineers, but also for journalists and those communicating the news. There were technical aspects that were difficult to explain at the start of the year, but with a few races now behind us, they are becoming increasingly easier to understand.

Many times this season, we have wondered how energy recovery takes place, particularly directly from the ICE. We know that one method is to use the MGU-K to recover energy from the braking system, but there is another possibility: regeneration through the use of the internal combustion engine. It is called clipping, or even super-clipping, a term used particularly frequently at the start of the season because of the incredible loss of straight-line speed it caused the cars.

What mechanically happens when clipping is used? The 130R provides the answer

Let us look at the circuit most associated with super-clipping, Suzuka, and analyse the section where drivers recharged the battery using this method: the 130R.

Using telemetry from 'GPTempo.com'—with George Russell’s Mercedes qualifying lap as our guide—we can answer many of our questions. One of them is: during the charging phase, do the internal combustion engine’s revs increase or decrease? They decrease. It may seem counterintuitive, but that is the case.

The crankshaft is connected both to the car’s transmission and to the MGU-K electric motor generator. As long as the ICE can deploy all of its power to propel the car, the car’s speed—as the graph shows—increases. It rises until it reaches a peak. That point represents the moment when the driver chooses to bring the MGU-K into play and draw energy from the ICE.

As a result, the engine revs decrease. From that point onwards, the crankshaft helps raise the MGU-K’s rotational speed. The reduction in engine revs causes the car to lose speed, as the crankshaft is connected to the car’s transmission.

Russell downshifts. What happens next?

As can be clearly seen from the graph charting George Russell’s lap, set in 2026 Suzuka qualifying, the revs (RPM) fall to a low of around 10'000rpm before climbing back to 11'000rpm. Returning to the speed graph, however, we can see that the car’s speed continues to fall.

So what happened? Russell downshifted. He did so to increase the revs driving the MGU-K and therefore boost battery charging. The speed stabilised, aided by the use of the lower gear, and once he reached Turn 16, he braked.

Even today, despite the regulation changes, it can sometimes be difficult to understand what drivers are doing in terms of energy management. Although super-clipping is no longer used, we invite you to study the 130R carefully to understand what actually happens when drivers choose to recover energy through the ICE. The 130R is one of the most iconic corners on the calendar and has always taught us something in the past. 2026 was no exception.

A small bonus

Understanding how energy recovery works in modern F1 cars can also help in everyday life. If you own a hybrid car—a full hybrid—we invite you to try the following. If you are looking for ways to use less fuel, try not to leave everything to the software. Make the most of the electric motor at low speeds, managing the throttle without sudden inputs. Be gentle with the accelerator pedal. Try to use electric power up to 50-60km/h without relying on the internal combustion engine.

When you are on a straight, or rather on a stretch of road where you do not expect to brake, try charging the battery using the engine. To genuinely save fuel, follow these tips while ensuring that the car’s battery remains at around 80%. You will see a significant change in consumption. Try it and see.
