Here's a fun little graphic from the factory manual showing the torque curve of the electric motor, or what the factory manual lovingly calls the "Traction Motor System." It would be nice if they labelled RPM and torque, but it still gives a good idea of the motor's torque band. The motor has a max speed of 7,200 rpm according to the manual.

Is there a link to this or is it only in the manual? I always want to learn more about the electric motor of the Q50 hybrid. One thing for sure, it's addicting when both the gas engine and the electric motor power the car at the same time.
I got this from the manual. Same here! That's why I wanted the manual. It gets into the real nuts and bolts of how things work.

That whole 100% torque at zero rpm always puzzles me about electric motors, but I file it away in the part of my brain that asks "if there was a big bang surrounded by nothingness, as the universe expands, what exactly is it expanding into". That part of my brain doesn't think. ;)
I'm venturing out on a limb to some degree, but I think the reason they have torque at 0 rpm is because there is potential energy to rotate the rotor from the electromagnetic charge in the coils even when the rotor is being held in place with the brakes. This contrasts to a gas engine where it is impossible to have torque without some rotation.

Some think our universe is a membrane that fizzles out and becomes less dense from its expansion to collide with another fizzled out parallel universe along a 4th and/or 5th dimensional axis to create a new Big Bang for both.

Others think we're the supernova remnants of a collapsed 4D star that fell into a black hole and our universe exists just beyond the event horizon. Apparently this new theory answers some mathematical problems that conventional theories had.

Whatever it is, this place is f**king interesting to say the least and at some point we may just need to accept that we'll never be able to answer why existence exists. It would still be nice to get a factory manual on it.

I'm just glad this universe made the Q50 because I like it and God clearly saw that it was good even if Car and Driver didn't.

I'm a weirdo. ;)

You know, I was just playing with an electric fan a few seconds ago and thinking about how it's just a simplified version of what's in the hybrid and I remembered how we talked about it being hard to picture torque at 0 rpm. I realized the fan is a perfect analogy to this. Just think about if you've ever stuck your finger in a fan and stopped it when it was on. There's no rotation, but you still have that torque from the motor pushing on your finger and trying to turn the blades. I think that kind of puts it in a perspective our brains can reference.
