2025/2026 Hybrid Powerunit speculation

[gruntguru]

The MGU-K will not ''brakes'' the ICE with 150kw when the ICE is putting out 400kw.

Time to put an end to this nonsense.

1. This is the energy flow diagram published in the above technical regulations. Note the arrow in the yellow circle indicating energy can flow between the ICE and the MGU-K in either direction.

.
2. This is the technical regulation on part throttle fuel limits. Why would you need to limit the fuel flow at reduced PU output - when the driver is already limiting the power with his right foot. The answer is "because the ICE is permitted to make more power than the driver demand - with the excess going to the ES via the MGU-K".

.
3. This is a table showing permissible fuel energy flow for four values of "engine power" ("PU power"?) using the formula above. For simplicity I have assumed 50% TE at all outputs. Note that at only 218 kW driver demand, the maximum 3,000 MJ.hr is available - i.e. full ICE output is available - but only 218 kW is going to the rear wheels - the remaining 199 kW is going to the MGU-K.

''Time to put an end to this nonsense'' Far from it. The 2026 formula 1 regulations depicts a bidirectional energy flow arrow between the ICE and MGU-K through a newly simplified power unit that removes the MGU-H. The MGU-K will now have a dual function: It harvests kinetic energy from braking to store in battery, and it can also receive energy from the ICE to deliver power to the drivetrain, creating a more interconnected system.

So. Now that the 2014-2025 hybrid engines that the manufacturers REQUIRED in order to use the R&D for road cars are expiring, will we finally get road versions of these 50+% efficiency engines?!?!? Or is it all still just marketing BS?
