Also people overlook the regenerative braking aspect. Every time you press on the brakes that heat is lost, not so for the PHEV as it can recover the long motorway exit slip braking for a few hundred meters of zero emission town driving.

I don’t buy the ‘green’ aspect to a PHEV at all.. but as a proposition, it seems a good’un.
Don't forget we've got regenerative braking on all the PSA Stop Start vehicles already - but it's only used to recharge the capacitor for the engine restarting. No good for 'The Sweeney' or a bank robber though :lol:


Don't get me started on stop-start :evil: , now that is a complete waste of time.

I don't think bank robbers have yet seen the benefits of a silent getaway vehicle :-D

All S&S types or just the ones with a reversible alternator?

Well certainly all the models I've seen. PSA jointly pioneered it in with with Valeo and was first fitted to the petrol C3 petrol back in 2004 - but more common in e-HDi forms now. Reversible alternator performing the starting, so no starter motor on that particular model.

Yes, that's my point. Does the supercapacitor also get charged on the overrun by a non-reversible alternator on cars such as our 308?

I'm afraid it gets a bit muddy here as to the different technologies incorporated. For example on the C5 X7 e-HDi Stop Start the battery diagrams show the following, compared with a 308 model the same as yours:
Paul X7 Capacitor.PNG
Paul 308 Capacitor.PNG
X7 Battery showing Ultracapacitor (1) and Converter Unit ECU (3)On the 308 1.6 120 Item (1) is a referred to as a 'Voltage Maintaining Device', but no sign of the larger capacitor here.
So whether different technologies are involved I'm not sure - I know that the Hybrids do specify regenerative braking - but I can't find reference to it specifically on the 308, which is not to say it doesn't have some form of it.
