Just like the aborted Nissan LMP project?
Given time & development that could have mixed with the front-runners.
Wasn't the Nissan lmp1 car basically the same pace as lmp2 at Le Mans? I don't see why that would have ever been competitive.
It never ran in competition with the electrical system, which lead to all manner of operational compromises. There was a deep-dive a while ago in Racecar Engineering that added the numbers for the electrical system and included the dynamic changes that would result. The results might surprise you.

It's a shame there aren't any modern, NA, V16 racing/sportscar engines out there, as I'd like to do a sound comparison with a V12. I'd expect a V16 (for a similar displacement and exhaust configuration) to have a higher pitch and sound like two flat plane V8s working in concert, but they typically (old versions) sound like higher pitched cross plane V8's. I'm guessing that's down to the exhaust manifold design/straight pipes.
The new Bugatti in development is using a Cosworth made V16 that revs to 9000 rpm, so you'll get your comparison in the next couple years.
In the video Bugatti released, the V16 sounded like two cross plane V8s to my ears.

Does it really amount to a 20s a lap pace deficit?
