Ferrari Head of Power Unit area Enrico Gualtieri provides details on the Maranello team’s upgraded engine ahead of the 2021 United States Grand Prix:

• doubled the level of voltage of the operating system of the energy storage.
• big changes to ERS system / energy storage / electric motors.
• redesign of the CE

Enrico Gualtieri:

“So far we are quite happy with the feedbacks that we have had from the track. It has been quite a hard work and the credit goes to all the people that worked on this project. We changed the technology raising the level of voltage of the operating system of the energy storage, closed to double. Every single bit of the ERS system changed to be somehow suited to this new operating condition. And get the most out of the level of efficiency. Energy storage was changed a lot, but keeping the same chemistry of the previous version. The electric motors had to change a lot. We had a lot of redesign and together with them also the control electronics. It is quite a bit of an upgrade. This is why it is so important for us to be able to anticipate the introduction of the new system by quite a fair amount of races. Running on different conditions, on different tracks is really important to be sure that we are going to shape the car in 2022 accordingly.”
