As I explained in http://tentenths.com/forum/showthrea...53#post3003153 and http://tentenths.com/forum/showthrea...03#post3003203 such rule exist in 2012.
In Le Mans the best 2 out of 3 designated cars score points and all other WEC rounds only 2 designated cars score points for the manufacturers title and |

I just re-read this interview with Treluyer from mid November.

http://www.autohebdo.fr/endurance/le...le-calendrier- has a short interview with Ullrich.
He claims that Peugeot was better on the ILMC tracks because they started developing/testing much earlier than Audi. While Audi was working on their Le Mans setup, Peugeot had already done their Le Mans preparation and could adopt their car for the sprint ILMC races. He also explains that they will only run with hybrid system if they are convinced that it has a performance advantage and if the system is completely reliable. |

audi used a map to have his engine more powerfull (but less fuel efficency) and had a much better efficency of tyres than peugeot for almost all the race long (the reverse happened at imola race). Then think about that the #2 had a perfect race with 0 problems while the peugeot #7 had the wurz indianapolis crash and gene slow stints, the #8 had some penality pit if i remeber well and the #9 too (the only and terribly slow stint of lamy can be considered a problem too). If peugeot dared less in 2010 and more in 2011 maybe we were talking about a 3hit strike. |

Also, Peugeot's Le Mans strategy was very much based on having a better fuel economy, an advantage that didn't really came into play too much because of the massive caution periods.
So in a way, the two Audi crashes were a good thing for Audi as they massively helped them in that regard. |

The whole story is just wishful thing and guess work. Duval is most likely going to Toyota.

Article at DSC Subscribers' section about the R18/R18H. It reports on the rumored 4 car entry at Le Mans and such rumors, but also reports on the R18's visibility issues. Anyone read that section of the article?

Yes, there is a picture of a model of the R18 in white that shows the screen "pillars" clearly and makes the point that in black they do not show up. If that is an accurate dippiction of these so called pillars there is no wonder the drivers complain of visability.

The cars problem is and has always been the fact that the wheelarches effectively prevent any meaningful sideways vision. |

Just read on page 91 of this months race car engineering magazine that the R18 hybrid system is infact the same williams based electro-flywheel system used by porsche in the GT3R Hybrid, the logic being that Audi are parts of the same group as porsche and it will also help Porsces LMP1 development.......shocker!!!......the information comes from Hartmut Kristen who is the motorsports director at Porsche.........I must admit to being very surprised at this news as the Williams system is a complex and weighty beast, looks totally un-related to road car technology and nowhere near as simple and light as Flybrids pure mechanical flywheel system.........If I remember correctly this Williams flywheel KERS system is shockingly heavy, 47Kg for the flywheel, 10Kg for the power electronics plus another 20Kg (approx) for the front axle based motor/generator, so approx 77Kg......... consider an F1 style KERS system weighs about 20-30Kg and its a real difference.....hmmmm........it must have been a packaging nightmare putting all that clobber in an LMP1 tub, perhaps thats another reason why it was re-designed???...

I often read that Audi and Porsche will compete with each other in 2014 with different technology and that the VW group has decided that Audi should use a diesel engine in combination with a flywheel based KERS and Porsche a petrol engine in combination with a battery based KERS.
Yes, the Porsche solution is very heavy, but is also twice as powerfull as an F1 KERS.

Finally, it is quite straightforward to replace the Williams flywheel battery with a more conventional battery (e.g., lithium ion) because the rest of the system is completely electric. |

hi gwyllion, thanks for confirming the motor-generator weight, mine was an approximation at 20Kg, but 45Kg is obviously a very heavy piece of kit!........I'm pretty sure the F1 KERS systems are in the region of 20-30Kg, it was a rough comparison in all honesty.......... but the point still stands, the williams flywheel system is one heavy mo-fo........it will be interesting to see how they all compare, for sure I cant see pug and Toyotas systems being anywhere near as heavy
have just dug our race engine magazine from aug 2010 for the williams -porsche flywheel feature.......they say that a braking event lasted about 2 seconds and this therefore harvests 240KJ with the 2 60KW motors........ the flywheel can rev to 40,000rpm - max......but at the nurburgring 24hr race they ran it between 28K-36K for safety reasons and were able to store 680KJ maximum.......the ACO rules state that only 500KJ can be applied (used) between braking events, so this williams energy storage system may be limited for LMP1 use, as its going to almost completley discharge between braking events........but perhaps thats ok???......who am I to say!!! |
