Look at the horsepower...

[PlatinumZealot]

Found this by a poster on auto-sport...
right click then view image....look at that horspower value for the 2010 car, top right page..



Yeah... that's right... 815cv. And all this time people (and me too) are thinking the 2.4 V8 @ 1800rpm were putting out the range of 740 to 760hp. Very interesting coz that's a strong engine! I really don't think the Benz engine is any more powerful after seeing that!

Dont know why but i cant right click and view image.

But if it says 815hp then its including KERS.

[Robbobnob]

the 2010 car didnt have KERS Holm,

IMO the Ferrari engine has always been as powerful if not more so than the Mercedes unit

[Holm86]

True. Forgot all about that.

But again can we believe those figures completly???

It's not 815hp I don't think. CV is equal to PS no?

[JohnsonsEvilTwin]

At the end of 2009 the Mercedes unit was marginally the best of the field according to auto motor und sport.

But, with all the exhaust fiddling going on it wouldn't be a surprise to see any of the 3 major engines(Renault, Ferrari or Mercedes) on top.
Its so close now that the engine itself isn't the differentiator it once was. Now there are other factors greater to car performance, like wing angle(witness Monza) Gearing(again monza) and specific circuit qualities.

1 CV = 1.01387 HP,,,, or so they tell me

[flynfrog]

I would take that poster at face value with no resemblance to real life

[PlatinumZealot]

It's a Ferrari poster, and the increase of horsepower of the V10's over the years seem to match Well with BMW's released engine papers. I don't think Ferrari would artificially inflate their engine power. ?

Inflating engine power is part of Ferrari's heritage. Or as Keith Duckworth (IIRC) said: "Italian horses are smaller than other horses."

It's the other way around.

If we move away from middle age units:

1 HP = 745.7 W
1 CV = 1 PS = 735.5 W

So 815 CV is just under 600 kW, or, for those who do like to hold on to units from the middle ages, about 804 HP.

Which is still significantly more than I would have expected, though.

I am new to this site but I have "history" on my side to contribute.
........................................................
P.L.A.N is the basis of Horsepower calculations and my expertise concerns,P= pressure *L= length of stroke *A= area of piston *N= number of revs
I have actual records which describe how where when and why the current Narrow Angle 4 Valve Technology was created in 1963 and how this was then introduced to the F1 environment through the Gurney-Weslake Eagle engine, the first F1 engine using this technology.
It is a technology which is now almost half a century old and yet is the current design of choice for combustion chamber design in the world's engines.
It gives insight to many of the questions that subscribers to this site are asking.
L and A, relative to Capacity are fixed but the book is about P (the Breathing which produces BMEP or Torque)and N (the revolutions per minute).

I will be happy to engage in discussion If I can contribute further.

They are only increasing engine performance by 1.875% Year on Year.

That isnt the same figure that Mario Thesien said that BMW did in 2009 and would have came with in 2010 if BMW stayed, of 3% to 3.5% power increase year on year. But then again there was more parts homologated in 2009 to 2010 for cost purposes.

Im just not sure.

It has been said that the Cosworth CA2010 started last year with 795hp, so a figure of 804hp for the Type 065 engine plauseable. But the Mercedes FO108Y has been rumored to be at least 20hp futher on than the Ferrari, with the Renault RS27-2011 only 10hp to 15hp lower than the Ferrari.

In 2009, with the new 18k limit all engines were believed to produce 725-745 hp. We know the BMW engine produced 741 hp. Given the restrictions, I don't think any of the engines produce significantly more than this today.

So I thought in the mid 80s they had around 1400 ps?
