Towing a Tesla at 70 MPH replenishes battery at fast charger rates

Makes sense. A MB C200 has 135 kW max from the engine, the Tesla’s battery is taking half of that, and losses in the energy transfer would be extra.

I don't think you have much losses in the transfer, the strap is probably efficient. Although they would be extra so you are correct.

GP almost certainly meant losses in the transfer from mechanical energy to chemical energy by way of the cars motors being used as generators, then charging the batteries.

Don't forget the double loss from sending the rotational energy to the ground and back.

Unsprung mass always surprises.
