Whereas the majority of the 2022 technical revolution in F1 is predicted on the chassis facet, the engine retaining its fundamental attribute launched in 2014, specifically being a V6 turbo hybrid, vital adjustments will nonetheless happen. To begin with, the gas will now must be composed of 10% ethanol, in opposition to 5% till 2021, which can have vital repercussions on its efficiency.
However the completely different dynamics of the single-seaters linked to the adjustments in the best way wherein the aerodynamic assist might be distributed guarantees to alter the strategy of sure corners by the pilots, specifically within the re-acceleration section. Nonetheless, this parameter is to be taken into consideration by the groups and the engine producers to work in addition to attainable on the effectivity of the ability items within the energy supply section.
Brixworth-based Mercedes engine division supervisor Hywel Thomas defined that the eight-time reigning world champion workforce had labored arduous in coordination with the Brackley chassis manufacturing facility to greatest adapt to this improvement. Nonetheless, each departments are able to make adjustments as rapidly as attainable if winter testing reveals considerations or points.
“The 2022 automotive may be very, very completely different”, Thomas stated in a video posted by Mercedes. “We all know the aerodynamics are completely different. And from all the things we have been instructed and all of the work we have completed with the workforce right here at Brackley, we really feel the automotive will do barely various things, and that the calls for on the driving force might be completely different within the corners in comparison with earlier years.”
“We have completed simulations, we have completed all of our calculations, and we have modified the engine and the best way it really works in an effort to be prepared. And we’ll be capable of react when the rider makes use of energy possibly from a barely completely different manner, possibly at a barely completely different time.”
“In fact, we’re determined to start out the primary monitor checks to see if these simulations are appropriate. I hope they’re. If not, we might be prepared to regulate [l’unité de puissance] if obligatory to make sure that the pilot has precisely what he needs when he asks for it.”

Thomas added that the brand new rules have allowed Mercedes to rethink its energy unit configuration and optimize its set up in keeping with the wants of the chassis engineers. “Yearly we have a look at the ability unit and the way it’s put in within the chassis in an effort to obtain the very best lap time. Because the 2022 chassis is totally new, which means that we’ve got had the chance to evaluation all the things once more.”
“There are areas of the automotive that might be notably essential for lap time. And there might be different areas that might be much less essential. And what we’re making an attempt to do with the ability unit is to ensure that we’re staying as far-off from delicate areas as attainable to offer the designers of the automotive as a lot flexibility as attainable, and in addition to pay attention elements of the ability unit in areas the place they are going to have much less affect.”
“So what which means is working hand in hand with the chassis division, and with all these engineers, to ensure that [l’unité de puissance] matches precisely the place it must, to make sure that we are able to produce the quickest general bundle.”
Lastly, Thomas additionally highlighted the difficulty of engine freezing, which can begin partly from the primary 2022 GP and can final till the tip of 2025. “[L’unité de puissance] has a frozen efficiency specification. And what does that imply? Which means from the beginning of the 2022 season till the brand new [moteur], which is predicted to reach in 2026, efficiency might be frozen.”
“And from the center of the yr, the electrical methods may even be frozen from a efficiency perspective. This means that we will be unable to make efficiency enhancements through the yr. It won’t be attainable to make reliability enhancements.
“So with the brand new gas, the efficiency freeze of [l’unité de puissance] over the course of the season, and the all-new automotive, all-new aero and adaptation of the [moteur] inside there’s a enormous problem for everybody concerned, and particularly the HPP workforce [High Performance Powertrains, le nom officiel du département moteur de Mercedes, ndlr].”
