Torque is the "force" of the engine and that is the most important. If your initial torque is high, than everything will be better. Put a F1 750hp on 18 wheeler, which is as usual close to 500hp... and the F1 engine could barely put the truck in motion... even in very high reduction gears... In WTCC the story was the same. SEAT with a 4 cylinder 2l diesel engine would had beat dead the obsolete BMWs and Chevrolets if it weren't for FIA changing rules all the time.. so a smaller engine also doesn't mean things are proportionally worst, because there are always ways to increase torque by increasing relative engine pressures and efficiency inside the cylinders, and increase power by reducing parasitic loads... which in a small engine its even easier to do than in a bigger one. Quote:
With last minute change from last draft in the fuel tanks capacity(reduce) i don't believe that neither Audi or Peugeot will go for a V8( the max).. but a V6 its quite possible, and since ACO in its stupid wisdom has limited the possibility of energy release to too low levels, it might be that the "energy recuperation" thing is only to drive the engine auxiliaries (gas,oil,water... whatever... pumps...) and reduce so parasitic loads, permitting the engine to rev higher and gain more power (hp)( which could be MUCH indeed for the surprise of many in this forum).. SO in case of a V6 its quite possible that no kers or other motoring tech will appear, and Peugeot and Audi will not be hybrids then, energy recuperation is for electric generation to drive the auxiliaries... more so because if the point is to gain MUCH power by reducing drastically parasitic loads, then a kers introduces parasitic loads... Kers by mechanical means should deserve a new name...TSHTE... the stupidest hybrid tech ever... Ok it was a clever trick in porshe to dispense with huge weight batteries packs... only because ACO refrains like a glowing carbon ceramic disk break the release of energy that would mandate bigger electric motors with back-EMF recovery and why not hub wheel motors of the same for 4WD... that could function in very smart 2+2 configurations ( 2 generating elect + 2 driving in normal, 4 driving in high acceleration; 4 generating elect upon breaking).. this would reduce batteries packs necessity to a minimal http://www.endurance-info.com/versio...ance-5594.html The feeling of the article author that the engine sounds less " aggressive" more muffled in this test, could there be an indication that there are not only a less cylinder engine but also exhaust gas pressure turbines( of some kind) in the system for electric generation(second phase "turbos")(digress!) ??

!!! (Notice that only the two fly bys are from this week's test... rest of the video is from the spring test) I guess this confirms it's a diesel. Last edited by deggis; 31 Oct 2010 at 03:04. |

What they had is much more torque ('force'), permitting them to run with more down force yet accelerate much faster than an equally powered Aston Martin (700+hp).. or even more so because of that(down force). Last edited by hcl123; 31 Oct 2010 at 03:31. |

Thin but they have to be integrally strong or the pretended effect will be minimized...
wonder if in this accident http://www.youtube.com/watch?v=lNkySVNNpog Ortelli's car had a fin and it had struck the R10, it would had cut the car and the pilot in half like a knife ! |

They want to win, their business is promotion by winning, not selling good but cheap obsolete engines to privateers... and they don't have top sports cars on petrol engines for commercial purposes and so promote it in LMS... so winning is the only option left for Peugeot... Diesel ? ... what is the surprise ? |

If both of the two most important manufacturers involved in the sport will continue to use diesel then the regulations will continue to make mockery of petrol engines for the next three(?) years and that's sad. Staus quo.

The regulations have been doing the possible and the impossible to lift petrol engines to near the level of diesel... OH! better said downgrade Diesel engines to the level of petrol ... Have you have ever "seen" any other sport where rules are changed in the middle of a season to penalize one particular group of contenders... and more than 1 time in the same season... and still be called a sport.. without tremendous public outrages ??? PETROL IS OBSOLETE... its time for you to face it. Those differences in efficiency that everywhere is well knowned from a long time, petrol up to 25%, diesel up to 35% and possibly more in Carnot cycle... ITS NOT SEMANTICS... its not noise that is indicative of power potential its efficiency... and 10% or more has been quite an hard ball for regulations to overcome. There aren't more contenders with diesel because of their market positions of the parts involved. But if Mercedes which has a very large commercial offering based on diesel... and also Toyota... would ever return to Le Mans, you can bet a high sum that they will came back on diesel Not that petrol is left with no applications in motorsport, example in motorbikes where the weight of the moving masses is very low, petrol is an excellent choice because it doesn't need that higher torque to outstand... In every motor sport where the moving masses gets close to 1 ton.. its clearly that PETROL IS OBSOLETE. Quote:
Motorsport is a business... and Peugeot objective is business oriented, and the only profit they can ever take from this large investments is by winning... only participating as a form of promotion is not an option for Peugeot, due to its market position and products.... profit is the motive, and they can only have it by winning, and so if they have to go for diesel to have higher orders of chances they will go, even if every "afficionato" hates diesel... ( why do you thing they busted 3 cars in order to try to win this year at Le Mans... when they could have settled and all 3 cars finish the race... the 908 broke because its bad ??.. no they broke because they pushed the cars well beyond limits because the only thing that mattered was the victory) Last edited by hcl123; 31 Oct 2010 at 04:49. |

Deggis, sadly this is not a video of 90X, it is all 908 so from an earlier test. If you stop the video at 4 and 15 seconds you see no fin, just 908. |

Oops... I guess the water spray (matches the Autosport spy photo, so it could be from this week's test if they brought the 908 too - actually the uploader's video description indicates so) distracted from noticing the lack of fin.

Also, the noise is definitely 908, the 2010 engine actually makes a certain amount of noise and it's a rather unique/recognizable sound.

[QUOTE=hcl123;2782789]Can't understand this !!!
PETROL IS OBSOLETE... its time for you to face it. hold on just a minute!!!......the only reason audi and pug used the diesel regs is because they were bent.......as many of you will know I work in the race and road car powertrain engine design business for 11 years now, for the last 3 years in a hybrid environment......let me assure you that if anything is dying its diesel, the cost to fix the excessive nox and particulate emissions is now becoming excessive for the end customer the net result being that diesel engines are now VERY expensive..........and gasoline fuelled engines are therefore making a big comeback, gasoline is the future from where I'm sitting and the projects I'm working on........by my sums the 2011 diesel regulations are still bent, so the manufacturers will probably go that way for a performance advantage of about 30% more torque.........but it would be nice to see pug go the 4 pot gasoline route as it will really differentiate them from Audi. |

That's not what I understood from the articles. I saw no indication from them as to whether the chassis was new, or old. Concensus seems to be that this was a new car, with Peugeot sources appearing to confirm that.

Neither did I and what I saw with a new engine sized at it appears it would be a new chassis.

Guys, can we please keep the petrol vs diesel balance of performance argument out of this thread and stick to discussing Peugeot 2010-2011. I understand that discussion has some relevance to Peugeot's decision making, but frankly, it's been discussed to death on here, has bored the majority of forum members senseless, and only really becomes relevant again when the new season kicks off at Sebring next March. Roll on March......

Turbocharged Bentley with roof intake:
http://picasaweb.google.com/lh/photo...zvLvCOD7r767pw I cant really figure out what the point is though, you need contorted ducting without any obvious advantage over the twin snorkels. |

maybe the air pressure over the roof is higher than where the snorkels are located?

For those of you that hope for a brand new car: This is it. Pug´s budget is what it is, and the powertrain-engine dept´s are gonna eat most of it. You can see all minor modifications to the chassis: in particular the tighted nose cone and somewhat sculpted sideponts. You just have to use the brain: why make detailed modifications to an interim car? Actually Peugeot Sport said this is the 90X, but that the engine config won´t be the definitive. And nope it´s not petrol but a V8 HDI DIESEL. Last edited by Senna-F1God; 31 Oct 2010 at 14:57. |

Wouldnt bother me in the least if it stayed like that , apart from that hideous centre wing .
Its still a diesel though , shame . |
