These fancy supercars come with "launch control". A mechanism that will rev in a high range (charging the turbos) and then release the clutch with full torque. I wonder if that helps...

Yeah the results on a dyno won't match the actual torque on the wheels when launching. It would be interesting to see a graph of how that happens. Torque vs. Time and RPM vs. Time on a two y-axis graph for an actual launch (maybe you could put sensors on the axles)
The torque curve on the Bugatti starts out lower for the first 1-2k RPM and then sticks at a significantly higher torque that seems artificially flat, likely limited by the rest of the drivetrain to save on weight (or ripping itself apart as opposed to the Tesla which would light on fire if the limiters were removed).
