Regenerative braking does work but, like other things in life, there's
no free lunch.Â* There are losses (heat, friction, induction, hysteresis)
in any system, electrical or mechanical, so you don't recoup all you
spent going up hill by going down hill.

The answer is yes, you can tow a glider trailer with a Tesla X (to some

Very interesting: thanks.

I'd wondered if hill-climbing impacted range, so that's clarified, but it
does raise another point: I thought that the extra energy needed to climb
a hill would be mitigated by regenerative braking on down-hill stretches,
but evidently not.

I also hadn't factored in the costs of running aircon, but over here we
do have cooler summers than almost all of your side of the pond has.

I suppose the an electric gets bitten in winter too, in the sense that an
IC car gets heating for free, while an electric needs to suck on the
battery to keep the cabin warm.
