Now i'm curious about how the levels of acceleration are varied for us with DEB and not so for you with DBC. i wonder if it is just your car not having this since it was sold with only D? or if this is true for EU cars sold with DCB?
Replying to a really old thread I know... but I wanted to add some extra information.
I've modified my 2011 Peugeot Ion a while ago to enable the two extra drive modes and there is in fact a difference in the accelerator pedal mapping in B and C modes compared to D.
For regeneration the amount of regeneration you get from only lifting the accelerator is approximately:
D - 50%
B - 75%
Touching the brake pedal lightly in each mode gives the remaining regeneration before the friction brakes are applied.
For acceleration B and C map the accelerator differently above about 12 o'clock on the power meter. Below 12 o'clock there is no difference in power output between the three modes, however above about 12 o'clock the power output for a given accelerator pedal position is reduced in B & C modes (by the same amount) compared to D mode.
This can be demonstrated by holding the power meter at say 2 o'clock at 60mph in D, then switching to either B or C with the accelerator held constant - the power meter will drop significantly and so will speed. At lower power levels there is no change in power output with mode.
So the cars acceleration definitely feels more responsive in the 2nd half of the accelerator pedal range in D, and the "kick" that you get when using the 2nd half of the accelerator in D is missing in B and C.
It's hard to be sure without measuring with Canion (which I will be able to do soon - just waiting on my OBD-II dongle) but I don't think the maximum foot to the floor acceleration is reduced, rather the linearity of the throttle mapping in the 2nd half of the range is changed.
Early Ion/C-Zero have the same drive modes as the Japanese/European i-Miev (and the same order on the gear lever) and only use a mechanical block to lock out the modes however I've read that later C-Zero/Ion's (post 2012 I believe - possibly the models that switched from 88 to 80 cells) no longer have a functioning C and B mode even when mechanically unblocked.
On these cars the dashboard will still display C and B when modifying the gear lever but the car will not drive at all or only very slowly in the extra modes.
On these later Ion/C-Zero PSA claim to have "increased" regeneration, presumably meaning that D mode has similar regeneration to what the unlocked B mode had on the earlier cars, and during this reprogramming of D mode the hidden B and C modes were nobbled.
