So the first car is faster “assuming all is the same” …..but it’s also stated it needs a more aggressive gear ratio to manipulate torque to do the same work potential? Genuinely confused haha
But to me it sounds like a 10 speed automatic (Because 10 manual is… absurd) with less torque but more power would be faster than a 6 or 8 speed manual with less power but more torque IF it had a more advantageous gear ratio. So to me it seems like although the more powerful car would technically be faster, the car with more torque would feel stronger?
Science help!!
Torque is generally at least somewhat associated with the size of the engine. An easy way to think abiout it is
4L engine at 4000rpm vs 2L engine at 8000rpm.
Momentarily the 4L engine is larger, but extending in the dimension of time, the smaller engine makes up for its smaller capacity by cycling trough it’s volume twice the amount of times in the same time-period.
Thats why when looking at an engine stats, you should be looking at two things:
Peak Power
The Torque Curve (the more torque low down, the better)
Peak torque is pretty much irrelevant if peak power is satisfactory
I think most of worlds petrolheads will agree that this is a topic that is to be left alone, for sake of our mental health.
What I’m wondering is in one of the last shots h small LEGO car (pull back car) drives off. I didn’t send string or his hand pulling it back. I thought it was my mistake and not a pull back (but I’m pretty sure it is) and it was reversed footage of it rolling backwards. I want to know how it was done
I feel like some of this is wrong. If the only thing that determines how fast a car accelerates is horsepower then why do we measure torque figures? I know torque is important, so I’m confused.

So many comments spread around here and on YouTube, could facepalm for hours. How do people not understand torque and horsepower?

Well that’s one of my childhood curiosities.
