With an F1 energy unit freeze in place because the begin of final yr, producers will not be allowed to ship any particular efficiency upgrades.
Nevertheless, automobile makers can nonetheless introduce reliability fixes, a few of which can additionally ship consequential energy positive factors.
There has even been speak over the winter that some producers have discovered double-digit horsepower will increase as the results of reliability enhancements they’ve carried out.
Talking at a press convention in Japan on Monday concerning Honda’s engine plans for the 2023 marketing campaign, its F1 undertaking chief Tetsushi Kakuda was clear that tweaks his firm have launched haven’t delivered such an influence raise.
Nevertheless, he says that refinements will assist enhance the way in which that groups Purple Bull and AlphaTauri can run their engines round a lap, and that ought to end in improved lap instances.
“Bettering the reliability is just not going to assist enhance the facility of the PU itself,” he mentioned.
“By regulation, there’s solely a sure kind of growth we will do with an influence enchancment. So, speaking about reliability, if that may be improved, that is going to assist with giving extra choices from a strategic perspective in how you should utilize the facility unit.”
Kakuda defined that Honda’s evaluation of its engine efficiency final yr confirmed that it was now the benchmark when it comes to its energy deployment, which doubtless contributed to Purple Bull’s straightline pace benefit.

“Final yr, I imagine all of the PU producers prioritised efficiency of their growth, and so did we,” he commented.
“We made each effort to recuperate the efficiency loss because of the E10 gas launched by the regulation change. However, consequently, the interior load to the engine elevated considerably in comparison with the earlier yr and the reliability was severely compromised.
“Because of this, a number of issues surfaced in the course of the 2022 season. Now we have been working to handle these issues for this season.
“Not solely should we enhance the areas the place issues have turn into obvious, but additionally we have now been getting ready ourselves to have wider methods by figuring out the bounds of every half and maximizing its potential.
“Along with bettering reliability, we deepen our understanding of our PU to additional optimise the management and power administration.
“Now we have additionally matured ourselves within the electrification applied sciences, the place we had a transparent benefit final yr, particularly the MGU-Ok deployment. As well as, we have now continued to work with our suppliers to enhance the precision of components when it comes to manufacturing, high quality inspection, governance, in addition to the precision energy unit meeting.
“HRC Sakura has been making an all-out effort for this coming season. So, we imagine we’re totally ready for the pre-season assessments beginning this week.”
