I'm willing to bet my Hurst spreaders will get the frunk open sans battery. If you're cutting the car, it's already totaled and limiting damage to the frunk would be the last concern on my mind.
I went back and rewatched it. I completely forgot they forced it. I first saw this a couple months ago when our TC used it for extrication refresher. I have to admit, even though it is staged and the car is completely intact, watching those guys is money. Super smooth execution. The way he handled the halligan solo to create the frunk gap was pleasing to watch.
Your spreaders will open it like a tin can...but did Tesla rev the location in real time during manufacturing?
