Lol wow, but to answer the guy on the video's question.
He got t-boned obviously, and it was hard enough to crumple in the entire unibody almost 24 inches. At an intersetction, so lets just assume the driver punched it WOT to make it through a red light, the engine was probably near redline.
The engine essentially "floats" on the motor mounts, same with the transmission. The powertrain is NOT solidly bolted to the chassis, it bolts to a piece of metal that is bonded to a piece of RUBBER. The severe force of the impact ripped the rubber motor mounts loose, at that point the rotational force of the still spinning engine causes it to twist violently in the engine bay as it rips free the transmission mount. Then the engine/transmission are SPINNING IN THE ENGINE BAY twisting itself free of everything else like your wiring harness, accessory lines like power steering/AC/etc.
At this point there is nothing holding the engine into the bay, it's completely free, driver realizes the impact and slams the brakes, 500 lbs of engine/transmission go flying forward through the radiator and tumble 50 ft down the road.
Now, a couple contributing factors, the engine mounts were either already substantially damaged due to the NOS the driver had likely been using previously (bottle was missing from the back seat). OR the motor mounts had been replaced with a very low quality item that failed. OR they were improperly installed, either with the bolts loose or stripped out. Good condition OEM mounts aren't going to crapastrophically fail like that unless they are already worn out and cracked. The G35 does have some infamy for worn motor mounts so it's possible they were just severely worn/broken OEM mounts.
Pretty funny video though, sucks for the owner of the car.
