2400 hp sounds like a lot, but a Model X Plaid is 1020 hp. I assume it couldn't output 1020 hp for as long though.

torque is the more important figure. Which is why 13l truck engines output only about 600hp.

I had an old coworker who had a fox body Mustang. He liked to say "Horsepower doesn't win [drag] races, torque does."

One day we were out servicing a conveyor drive with a 5hp motor attached to a gear reducer. I pointed out the spec plate on the reducer, it claimed an output of more than a thousand foot-pounds of torque.

"So this thing should be able to beat your Mustang in a race, eh?"

Horsepower is just torque * RPM.
