Do you think from this point on they will improve significantly from the 2015 qualifying times from this point on? Sebring (1 min 58), Long Beach (1 min 17).

At circuits with corners they should improve their times. The cars have more downforce now, which may have held them back at Daytona.

Might BMW go to LM next year once they've completely mastered their new car (which engine is turbo charged for the first time in a GT3/GTE car) and are convinced their top speed is a match for the others???

Youre question has already been answered by JoestEver.

The GTLM version of the M6 is just a modified version of the M6 GT3 (although being developed parallel at the same time) the GT3 version is the prioritised one and the GTLM version is just the least amount of modifications thay had to do to make IMSA happy to race in GTLM class. They had no intent to race in any GTE serie (i.e Le Mans) so they have probably never even asked ACO/FIA what it would take to get GTE homoligation for it.

If BMW wants to make the M6 go to Le Mans they will, but they will likely need to make quite a lot of development on the car and/or make a lot of lobbying with ACO/FIA.

Dies this mean the Ford GT cannot be entered in Am? Or does it run to the same BoP as in Pro because it's Ford's first year and there is no one year old spec for Am. But one would think that it would be BoPed differently for Am as the new cars should be faster or did the ACO make sure that the new cars have with the BoP similar performance compared to the old cars?

[Deleted]

They know for fact Ford isn't renting the chassis to any customers. As do we...

[Mitchi_S]

Was't it that you can only enter a car in AM that is at least one season/year old?

Which the Ford isn't ...

No, "newcomer manufacturers" can get waiver around it...

[Mitchi_S]

Ah alright.

Is that just for factory squads?
Larbre moved to LMP2 for a year a couple of years back as they couldn't run the new 'Vette in GTE-Am, right?

[carbsmith]

Pro and Am are totally separate classes with different technical regulations this year. None of the cars are even listed the same because they're different homologations.

911 RSR (2016) vs. 911 RSR (991)
Vantage vs. V8 Vantage
C7.R vs. C7 Z06

Obviously no 458 listed in Pro either.

S365:

SRO’s GT Sports Club should have 20 cars on the grid for the season opener at Misano. The series aimed at amateur drivers will also welcome a second GTE car, as Selleslagh Racing Team will field a Corvette C6.R GTE. The Belgian squad used to field Corvette GT1s in the FIA GT Series several years ago.

Pretty sure these is the first LMGT2 influx on SRO grid anywhere since Spa 24 Hours 2010.

edit: actually it seems there were some GTE Ferraris on the grid last year, my bad

The previous pre-HTTT round of adjustments PDF has been hidden from the FIA committee page, but you can compare these values to the PDF I linked up on previous page, as the URL for it still exists. They may play this sort of "nothing to see here" trickery later in the season too

Well there really isnt anything to see there, theres no changes, only thing they've done is to specify the fuel rig restrictor, which were TBD in the previous document.

Not in this particular instance, but in the future it's good to know as the season-long changes aren't that transparent in these (newer) PDFs without comparing to the old files

It seems Ford and Porsche don't like being treated differently by the ACO and IMSA. They are calling for a unified BOP between series:

http://sportscar365.com/lemans/wec/g...n-imsawec-bop/

[GT6]

It would be nice but i can't see both series agreeing on anything

[TF110]

Imsa has so many bop changes it'd seem hard to keep up. But the wec hasn't been much different so who knows.

[Akrapovic]

IMSA BoPs takes into account the teams and drivers too much for that to work. I'd much prefer the ACO to set the BoP and IMSA to just adopt it.

But then BMW would have to make a legal car :P

[Coach Ep]

Hmmm, let's see:

- In favor of equal BoP
Ford
Porsche
Corvette? Only if it improves their LM chances

- Not in favor of equal BoP
Ferrari? They have a stronger presence and run stronger in WEC
Aston Martin? No IMSA fans obviously

no clue on BMW.

Seems there's too much difference among the various manufacturers to get both sanctioning bodies to move. Might be rather similar to the failed GT conversion excursion?

[HORNDAWG]

Unless it is the IMSA BoP, it will not happen. IMSA has a much smaller window to fit in than the ACO does.

The speed gap between even the slowest LMP2 cars and the fastest GTE pro in WEC is still larger than any speed gap between even the fastest DP/LMP2 cars and GTLM in IMSA. I'm sure WEC can do something to equalize their BoP to IMSA.

[TF110]

Probably because those continental's P-class runs in imsa.

I actually wonder - even if all 5 manufacturers agreed to use a common bop, would ACO/IMSA oblige? The series have their own agendas and other classes to worry about as well.

Exactly.

Laguna Seca:

Lamborghini Super Trofeo = 325’000 $ = 1’23’’885

Ford GT / Corvette C7R / Porsche 991 RSR / etc. = 700’000 to 900’000 $ = 1’22’’867…

IMSA GTLM 2014 : 1’22’’373
IMSA GTLM 2015 : 1’22’’362
IMSA GTLM 2016 : 1’22’’867 (with new cars spec.2016…)

Spa Francorchamps 2015:

GTE (WEC) = 2’16’’840 (with Michelin tires confidential)
GT3 (French GT) : 2’17’’025 (with Michelin tires customers)

Nürburgring 2015:

GTE (WEC) = 1’54’’275 (with Michelin tires confidential)
GT3 (Blancpain GT) : 1’54’’538 (with Pirelli tires customers)

Which is really the interest of the category GTE/GTLM ?

No faster than the GT3, clearly more expensive and balance of peformance very present.
