Watched a video of some dude recently (engineering guy or something) drive across frozen Canada or some such and pull some seriously impressive mileage in sub zero temps. Very impressive heat management.
The latest ones (with the heat pump) use barely any energy when heating the cabin any more. Also, with pre-warming (if you can), the actual energy efficiency of the motor is ridiculous too.
100%. Looking forward to doing a 600 mile day in August down to France (lockdowns etc willing).
