Is the 4.0 GT2 based engine rule the seize for GT2 of just the max that can be brought over to LMP2? I didn't see anything so far about the GT2 rules for 2011 and beyond. And would GM be allowed to run a 4.5L if it was downsized from a 5L+ Vette street engine or would that end up being classified as a race engine and then be limited to 4.0? Think it would also end any Vette engine in an LMP1, something about a 3.4L engine just doesn't sound like an workable size for the name. Maybe a GM make but a Vette?

As to the 2011 rules being so clear. Sorry, they're not! We have already seen the ACO waffle on hybrids, while I would agree that the outlines that have been set out are probably pretty firm for the standard (per se) cars. But we (IMO) should also take into account what is not been put out, in context with the current clime. The ACO is in the process of re-defining the GTs and as such the top GT homologated engines that could be allowed into P-1 are still in flux. We also know that the rules are still under evaluation by the ACO per Jean-Claude Plassart, Here , paying attention to the last section. L.P. |

Autosport is reporting it too, saying a debut at this year's Petit Le Mans could be possible. I also quote the following from the magazine:

It will certainly be nice to continue to hear the rumble of that big Chevy engine for at least a little bit longer! Also, for the future, would it be possible to resurect the 3400 cc V6 from the old Corvette GTP days?

Postponing to 2012 would actually make a lot of sense... it would help all of the current manufacturers involved (except Mazda - no automatic move to P1). One more year for R15, ARX-02 and possibly DBR12. Would also ease Peugeot's situation, if they actually plan to continue after this year, since they're not going to build a new car just for 2010 (unless ACO is planning to mess up things by making 2011-ready engines competitive). Why would Panoz want to be in LMP2? |

I am prepared for the (sad) scenario that the engine regs will be just like that. I hope for a defensive victory though. Then again not much materialized from the original "EVO" plans even though it is not same situation. |

Something to keep in mind is that Chevy (GM) does make other engines than the LS V8s... could be something very different. |

And here is all engines produced by GM in 2009 They can down size the 3,5l V6 LZ4 used in the Chevrolet Impala to 3,4l? |

When you use direct injection, do you still have these trumpet problems?
Otherwise turbo's (or compressors)??? (though they wouldn't fit the panoz image I think). |

With all the replacements which it will need, then wouldn't it just be better to build an completely new engine, for a little extra cost!? (an engine which is optimized for the Panoz if they choose it!) |

One of the main objectives of the Panoz LMP07 was to have a greatly reduced frontal area when compared to LMP 1 Roadster S. Sitting a 5 litre plus V8 out the front combined with rear tyres on the front is going to have the aerodynamic efficiency of a house brick. In J.A. Martin and Michael J. Fullers book GTP Race Cars (Must have for all Sportscar fans) there is a drawing by Bob Riley of a front engine GTP car using a Porsche twin turbo flat 6. I have often thought that this kind of engine would have been ideal for the LMP07. Having said that I don’t think a N/A 3.4 litre flat 6 is going to be able to compete with a 3.7 litre twin turbo diesel.

would cool to see an engine similar to the turbo Caddy NorthStars.
regardless, i think we are all missing the big picture (besides the fact that my FAVORITE brand will be back in prototypes) is the step away from Elan Power for GM. I thought Robert Yates and/or Ford built the engines for the one of LMPs. according to mike, it was Elan and Zytek: http://www.mulsannescorner.com/panozlmp1.html http://www.mulsannescorner.com/panozlmp07.html o well.... but like i said, i feel that this is big for GM to get back in P racing, no matter how small an effort, especially considering their financial state. |

Will the car be supported by GM?.
Isn't it just the engines?, and that might as well be paid out of Panoz own pockets!? |

There is an upside, the ACO can leave engine regs alone for the forseable future, so manufacturer's can invest in engines without fear of them being banned/restricted.
Out of the blocks they'll have 550bhp, so it will be interesting to see the race to 600bhp+, P2 in recent years gave us a glimpse of the potential of these engines. The ACO needed to this as they'll be spending most of their time intergrating hybrid technologies. |

All of the discussion with Scott Atherton and others during the Speed TV coverage of Sebring seemed to be saying that the Panoz return to LMP1 was an unfounded rumor. Did anyone else also get that impression?
