Seriously, what actually happens if a hybrid gets towed?

We know that the front wheels are permanently engaged with the planetary gear set known as the eCVT, so if the front wheels were on the ground during towing, MG2 and other components would be spinning.

I haven't seen a diagram of the rear transaxle, but there has been no mention of a clutch, so I assume that the rear electric motor would spin if the rear wheels are on the ground during towing. Question is, how is that different than normal driving (cruising without added rear power) when the front wheels are providing traction and the rear wheels are being passively pulled along? Despite the warning, I'm not sure what harm would be done.

I'm not about to try it, however.
Spinning permanent magnet motor will cause it to generate electricity. However, how much damage that might or might not cause it the question. The electricity will be fed back into at least some of the electronics, unless there is a disconnect right at the motor, which I don't think there is. Spinning the motor could conceivably generate hundreds of volts. But the system is designed to run at hundreds of volts, so it' s not clear what sort of issues that might cause. One would need to see a full schematic to even speculate.

and yes, moving it a few feet at very low speeds is likely not an issue.
