ACO vs ALMS regulations

[topgun]

Hi all,
I'm a new member of the forum... Reading some of the threads I heard that there are relevant differencies between the ACO and the ALMS regulation, especially for what concerning the minimum weights and the fuel capacity of the LMP cars.
Could someone of you gently summarize the IMSA-ALMS weights and fuel capacities for the LMP cars from 2006 to 2009 please?

Thanks in advance

thats kind of a task, that I am too lazy to look into, but here are the points as I know them,

IMSA changes the ACO weights and restrictors, so that we could watch Lmp2 and Lmp1 fight for the overall wins, while the ACO in the past years has clearly tried to diferentiate LMP2 and LMP1, While imsa wanted them more close together, For 2010 I guess IMSA won , because now both LMP2, and LMP1 are one class LMP.

for all the specific information about witch changes exacly have been implemented go to imsaracing.net Bulletins under Bulletins you should find all performance adjustments that took place.
Hope this helps

To be more clear, in 2007 and even more so in 2008, IMSA adjusted LMP1 and 2 performance to make them competitive with each other.

In 2009, it went back the other way, separating the classes, largely because of pressure from the ACO. That has turned out to be a racing and spectator disaster. From many winners and close raciing in 2007 and 2008 (Audi won 11 over all, Porsche 11, and Acura - in its first two seasons - won 2). In 2009, Acura, fielding the only two competitive P1's won every race. P2 was "pegged back."

For 2010, IMSA has announced that performance will be balanced between P1 and P2 prototypes, making a single prototype class. The specifics of weight, power, and aerodynamics to make that happen have not yet been announced.

When they are, it will be available in bulletins at the link posted above.

All the noises from IMSA and ALMS are that the P1s will be slowed down rather than the P2s sped up.

Sebring and Petit Le Mans will still run to ACO LMP1 and LMP2 due to the Le Mans entries they can secure and the greater number of European teams that race those events as one offs.
