The 50% is with Battery assist. Without battery assist is about 40 to 42%. I think they are aiming for 50% self sustaining though.wuzak wrote:50% thermal efficiency would mean 830hp....
And if that is without the MGUK, the total would be 990hp!!!!

As I said before, ES cannot be used in efficiency calculations. And I doubt that Mercedes do so.PlatinumZealot wrote:The 50% is with Battery assist. Without battery assist is about 40 to 42%.

Cosworth apparently released information on their V6T which showed that of the 160hp the ERS is capable of generating, 100hp was in self-sustain mode from the MGU-H.Blackout wrote:Could you explain again what everybody means with ''self-sustaining mode" here?
AFAIK Cowell said:
V6 turbo with no ERS = V8 with no Kers = 750hp
V6 +ERS = 750 + 80 + 10% = 913hp
750hp (v6 alone) = 45,1% but 913hp = 54%
How does the MGU-H feed the ICE with more power?Petroltorque wrote:V6T power output alone is 610bhp. The nexus of the Mercedes performance is the ERS-H. It's technology that harvests energy from the compressor/ turbo and feeds the ICE with an additional 60bhp. Th ERS Kinetic is worth 160 bhp. So total output Is 830bhp. It's the way Merc manage the software that helps them maintain peek output fo longer.
I can't take credit for this as it was explained by an motor engineer working on the unit. 900bhp as he put it is pure fantasy.
He can't explain it because it is not allowed.Petroltorque wrote:He did not explain how they extract the extra bhp from th ERS-H but hinted it's clever software. He's not going to reveal th company secrets.
Petroltorque wrote:There seems to be too much confusion. These PUS only have on source of energy ; supplied fuel. That is limited to 100kg. If the miracle efficiency of 50% is achieved from 100kg fuel that is 830bhp. You can't then simply add the 160bhp from the ERS because where will that energy come from, the local nuclear power plant? Once you have extracted the energy from the fuel that is your lot.
The trick seems to be extracting as much power from th ICE / TURBINE / MGU-HEAT since that efficiency is driving performance. You can apply peak boost from the batteries but even that stored energy has to come from the fuel.
I think the confusion is very much of your own making. You should start distinguishing fuel budget and fuel flow rate. Also the MGU-H cannot magically give 60 HP to the engine. Its electric energy is either stored in the battery or transfered to the MGU-K. "60+160" electric power is nonesense.V6T power output alone is 610bhp.
