'gliding' is best for efficiency, yes. But not at the expense of safety. If doing that downhill is going to mean that you don't have control of your speed, then it's not a good idea.nkane wrote: ↑Wed Jan 20, 2021 11:15 am
I disagree here. Don't you want to be gliding downhill whenever you don't need to be actively slowing the car down? Say on a long straight downhill. You've already paid for the energy to get up the hill - if you regen too hard, you'll need to accelerate sooner. That's inefficient. And when you're topping a rise, you want to accelerate just enough to get you over, and then immediately start gliding downhill. it's much easier in B0 to just let off the gas than to precisely modulate the pedal in any other setting.
And in B0, you can give your calf muscle a rest for a minute when descending. That's nice on a long drive.
You'll find if you drive in B5 all the time, it's pretty easy to find the 'balance' point of where you're 'gliding' and even if you're not spot on a few kW here and there makes very little difference to the overall efficiency. It's still better than throwing all of it away on mechanical braking which you will do sooner in B0 than B5.
In the end, it's user preference but you said that you didn't want to be constantly changing B modes so the most efficient way of recovering energy on a hilly drive in a single B mode is in B5, not B0, especially with skilful use of the pedal which can replicate B0 anyway.
