One thing about OPD or regeneration.
This weekend I went up from my city (about 660m) to the mountains (1830m).
The trip was 80km in 1h10': Consumption 22.6 kWh/100km. All uphill without OPD
The return was 68km and during the steepest part of the descent with the OPD active.
Consumption 4.2 Kwh/100 km on the return trip. (Yes 4.2kWh in 68 km. It added to the battery about 3-4 kw during the steep descent)
If I add them up it is about 150 km. And if I take an average of consumption, it shows that the total consumption was 14kWh/100km. Which is very low.
The conclusion (not very reasonable) that I can draw is that the car consumes less, on symmetrical ups and downs, than on the flat (using the OPD with some logic). Strange.
How economical is your driving?
I always have OPD on, never ever driving without it.
I regularly drive a short return trip of a few miles from my home to a hilltop lake nearby.
I have not measured actual consumption in kWh, but it always takes exactly 4% of my battery to go uphill from my home to the lake. Coming back home down always takes either 1% or 2% (I assume that the reason it varies between the two figures on the way down is that the actual figure is somewhere between the two, but the car does not display decimal places).
Every single time it takes at least twice as much range to go up compared with down.

The difference OPD over “standard’ makes to range is difficult to calculate. In both modes the car decides which braking system to use (regenerative or friction) which further complicates the calculation. OPD should be more efficient although its main feature is to provide an alternative driving experience.

If that is correct how does the car decide which braking mode to use? Certainly, if going downhill on a slippery surface the rear wheels will lock if in OPD. But they don’t if using the foot brake. And hill decent works really well. But it’s all completely manual, the car decides nothing as far as I can tell.andrewollason wrote: ↑Wed Oct 23, 2024 7:50 am In both modes the car decides which braking system to use (regenerative or friction)

I think it is a fairly straightforward calculation based on how much retardation is being requested by either releasing the accelerator pedal or by depressing the brake pedal. Same principle in both modes with obviously more braking effort requested by the accelerator pedal in opd mode.

I have always thought it would be interesting and useful if the trip info would show how much energy had been regenerated for the trip ? I had a 2012 Toyota Plug in Prius - and that would show how much energy had been recovered over the last minute or 5 minute interval using small symbols on a graph of fuel consumption- one symbol was either 30wh or 50wh depending on the time interval you chose (I was never sure what they symbols were - I think they were small cars?!)

I challenge anyone to get below 33Kw/100 miles in an ultra AWD. You'd have to drive everywhere below 50mph with heating/aircon off!
These cars are NOT frugal - batteries aren't cutting edge.
I drive my Tesla M3 hard and it averagres - 243w/mile.

I think the Plus is marginally more frugal? I assume the smaller wheels? I did a 92mile trip to London and they had to come back from Heathrow which was 85 miles. On the M1 I must have averaged about 50mph most of the way lol due to average speed road works and only managed 32kw/100miles
BUT on the way back I came back on the M40 and it was one of those where I wanted to get back quickly so may or may not have absolutely panned it back - mostly at 90mph! But again it was 32.5kw/100 for that leg? So didn’t seem to make a difference if I was going slowly or going fast? I had AWD on both legs and the ACC.
