I dont expect the fuel consumption to be great.
The gibson 4.5 will need a direct injection conversion to be competitive, so thats new heads and pistons straight away, and a lot of development time, so to get all that ready and reliable for the start of the WEC season is already tight in terms of timing.

Actually aer p60 is a quite high rev engine despite being twin turbo.
In 2015-2016 in the back of rebellion, drivers shifted up close to 8000rpm.
Engine was however powerful and had a good fuel miliage overall (the usual stint window of about 40-45 minutes, can't remember if it was a 75L fuel tank or larger). If the power target will be raised up to 700hp, guess will be required a larger fuel tank.
Gibson, no matter if a updated old 4.5 or modified more recent 4.2, will need to rev up close if not over 10000rpm. Of coure could be required a larger fuel tank as well (or maybe not.... cadillac dpi this year started with a 75L fuel tank and received a 64L nerf.... but however kept the same fuel milliage for some unknwon reason).
