If you've ever tried to understand the difference between horsepower and torque, you've likely come across this silly expression: "Horsepower is how fast you hit the wall, torque is how far you take the wall with you." And while I created a video without the use of bad analogies to explain the difference between the power and torque (https://youtu.be/u-MH4sf5xkY), the comments were flooded with the inaccurate meme anyways.
Unfortunately horsepower and torque shouldn't be oversimplified to a short analogy, even if neither of them are all that difficult to understand individually. In this video we'll analyze the expression, and discuss exactly why it is inaccurate, what a more accurate analogy would be, and hopefully clear up additional misconceptions about power and torque through the use of dyno plots and a comparison between a diesel engine with lots of torque, versus a gasoline engine with not much power.
