The PU is frozen so nothing can be changed and radiators are not part of the sale of the PUs. Each team has to build their own, along with the exhaust.Spoutnik wrote: ↑12 Oct 2023, 14:19That's exactly what I was trying to say !AR3-GP wrote: ↑11 Oct 2023, 16:57PikeStance wrote: ↑10 Oct 2023, 10:42
Ferrari and McLaren use two different PUs. I believe Mclaren uses its own gearbox and only uses Mercedes HPP PU like Mercedes. Most of the differences in performance will be in areas outside of the Powertrains, like chassis, aero, suspension, etc... Outside of of Powetrains reliability, I do not see how Ferrari OR Mercedes (Gearbox difference) would have any advantage. Zero pod refers to aero and not to the Powertrain.
See below. The Mercedes power unit packaging was determined by zero pod aerodynamics. Mercedes now that they are switching away from Zero pod will repackage the power unit which will enable better thermal management and more power next season. The Mercedes customer cars have all struggled with PU temperatures in the races. I don't have time to dig out all of the sources, but the issues have been there all season even if not heavily reported on. The Merc PU is compromised. Mclaren is defenseless against these kinds of decisions because they are only a customer.
https://www.formulapassion.it/opinioni/ ... nza-motoreThe change of concept regarding the side structures of the car has already been partially introduced this season, with the new bellies already oriented towards the RedBull philosophy, but, obviously, it was not possible to carry out a redesign and modification of the components of the Power Unit for the current season. The 2024 car, however, will be born directly with the new philosophy, both as regards the bottom and as regards the upper part of the car, and the space limitations will become decidedly less stringent, with the possibility of a "re-packaging" of the drive unit that will give at that point much more comfort to the internal components, gaining in reliability (and therefore in percentage of use) and, especially, of course, in pure power. We spoke to an engineer from the team who confirmed all this, stating that the aggregate that Mercedes currently uses was designed for the zero pods concept, with very small dimensions and a cooling system inevitably reduced to a minimum. Despite the limitations set out so far, our contact told us that the data analyzed at Brixworth tell of a driving unit that does not fear comparison with rivals, and indeed in certain conditions has even proved to be the most effective. For this reason, at Mercedes there is a fair optimism on the engine front for next season, when the reorganization of the hood volumes and "sidepods" (the bellies) will allow a more generous layout of the components and sizing. We will therefore see if in 2024 we will find a Mercedes Power Unit again able to excel and overshadow rival units as already happened from 2014 onwards.
