Actually it does change charge level.
If your entering a steep sloap/hill and the percentage has just decreased with one percent regen can recharge that percent, or just enough for it to increase the one percent it just decreased.
B mode is on a button in the e-tense 
Totally agree
I agree,
I’ve seen the regen % increase if using B mode.
So the brake lights do illuminate but only if the car slows at at specific rate ?
That seems to be the general opinion when reading up on this online.
I also found that it seems to be, that the rate of slowing that illuminates the brake lights differs on the make of vehicle, at least that what owners are reporting.
I came across one thread for MG that said the brake lights illuminate as soon as the foot is lifted off the accelerator and regen was operating.
Because these Hybrids (PHEVs) have small (about100bhp?) electric motors the amount of regeneration possible is low, compared to Full Electric Cars (BEVs). If you have a bigger motor/generator then the amount of braking achieved is also higher, more inertia. I have read somewhere that anything above 0.7 m/s2 must trigger the stop lamps, and I think the system we have does not achieve this level.
Stu, you wanna hear something stupid?
Setting a destination in one of your phone’s map apps (via carplay) nullifies any destination set in tomtom(built-in) satnav. 
You simply can’t have Waze running simultaneously as tomtom, even though Waze (or other map app) can’t be displayed in the cockpit dash. How stupid is that?
So likely that’s why I haven’t seen the battery management behavior you’ve been talking about.
I’m so used to always running double GPS’s (always get a second opinion, I say…lol) but apparently I have inadvertently disabled the tomtom by also setting the destination in my phone.
Anyhow, today was the 500km trip I said I would test it with.
Since I haven’t got charging at home, 22km was what I could manage to start with.
I did a few unannounced stops (coffee, gas) but I had 6km left after the last stop before I ran out of battery with 171km left to drive.
So in conclusion, yes, today I could see that there was some management going on, but I still had a long way to go when I ran out.
Maybe it was the unplanned stops that messed things up for the system, but I dunno.
Maybe I’ll have to test it a bit more.
A possible way around your “2nd Opinion” option could be to make sure Waze goes nowhere near the car system, disable it from Carplay.
Anyway, I may be wrong but have been doing some research, According to Copilot - not sure how accurate this is but … some manufacturers, Toyota is one of them, do use map Topography to assist drive choice of their PHEV’s but PSA vehicles do not. They just use live traffic and weather data - as I said jury is still out how accurate this is.
I traveled 147miles (240km) at 70 mph (110 km/h) loaded (15 day holiday for two) and my car returned 58.4 mpg (4.84 l/100km) that’s what makes me think that using the inbuilt SatNav really does have a effect (Oh, and on the way home 166miles @ 61mpg)
As for unplanned stops, can’t see them being a problem, as the system would surely still be planning for the final destination - As I said in earlier post, when visiting uncle Bob, use Bobs address a a way-point and home being your final destination.
Hope you have a safe good drive on your next test and it would be really interesting to know how you get on.
