The beginner’s guide to F1 power unit penalties

Power units often become hot topics as F1 seasons develop, given the rules on allocations for each driver and the penalties that follow if they are breached. Our beginner’s guide has all you need to know about this vital part of an F1 car…

Firstly, it’s important to understand the various components that make up F1 power units – which are brand new for 2026 – and how many can be used across the 24-round calendar without penalty.

How many components are in an F1 power unit?

F1 power units feature several elements: the Internal Combustion Engine (ICE), Motor Generator Unit-Kinetic (MGU-K), Turbocharger (TC), Energy Store (ES), Control Electronics (CE) and Exhaust (EX).

Over the course of the 2026 season, a driver may use no more than four ICEs and Turbochargers, three MGU-Ks, Energy Stores and Control Electronics, as well as four Exhaust sets. However, given the new regulations coming into play for 2026, one of each of these allocations is considered a 'bonus'.

Therefore, from 2027, the allocation will drop to three ICEs and Turbochargers, two MGU-Ks, Energy Stores and Control Electronics, and three Exhaust sets.

Additionally, if the power unit used is supplied by a manufacturer who has not supplied power units in 2026, and is in its first year of supplying power units, the relevent team would also be granted the additional 'bonus' allocation for that season. Cadillac, for example, plan to use their own power unit from 2029.

How are F1 engine penalties applied?

Should a driver use more power unit elements than the numbers set out above, a grid place penalty will be imposed upon them at the first event where each additional element is used.

The first time the allocation of any one of the elements is exceeded, a 10-place grid penalty will be applied, with the second time this occurs (and so on) resulting in a five-place grid drop – all penalties at the same event applying in a cumulative manner.

If a driver incurs a penalty exceeding 15 grid places, they will be required to start the race at the back of the field regardless. Following some confusion when multiple drivers received multiple grid drops at the 2022 Italian Grand Prix, the FIA clarified the penalty application process.

Classified drivers who have received 15 or fewer cumulative grid place penalties will be allocated a “temporary” grid position equal to their Qualifying classification. So, if a driver qualifies 10th and they have penalties totalling 15 spots, they will be placed in a temporary position of 25th on the grid.

Should two or more drivers share the same temporary grid position, the driver who finished lower in Qualifying will keep that position and the faster driver will be placed immediately ahead.

Once the unpenalised classified drivers have been allocated their positions, those in temporary slots will be shuffled up to complete the grid.

Any driver who has a penalty of more than 15 places – or if they have a punishment that pushes them to the back of the grid – will start behind any other classified driver.

A new power unit element is viewed as ‘used’ once the car’s timing transponder shows that it has left the pit lane during an official session. Meanwhile, power unit components are sealed to ensure that parts cannot be replaced without the FIA knowing.

If a driver introduces more than one of the same element that is subject to penalties, only the last element fitted may be used at subsequent events without further penalty.

Meanwhile, if a driver is swapped out for another at any time during the season, their replacement will be viewed as the original driver for the purposes of assessing power unit usage.

It is also important to note that when a new power unit element is introduced, it becomes part of the driver’s ‘pool’ for the rest of the season – those parts that can be swapped from race to race without penalty.
