It appears that a few months ago Citroën started selling cars (C3 and C4 Grand Picasso) with the second generation stop-start system mated to the 1.6 liter HDi engine. Here is some info on it:
Press information on PSA's e-HDi
EDIT:
Here are two interesting things about this Stop-Start set-up:

The StARS starter alternator is a synchronous machine using three-phase current. The rectification of the alternator current to battery current (AC/DC) is realized with so-called field-effect transistors instead of diodes, which gives an excellent efficiency at >77% (VDA measurement), or 10 points higher than a traditional alternator and thus allows additional fuel savings, independently from the engine stop phases.

If only all alternators used field-effect transistors instead of diodes...
Quote:
E-Booster system with 5 volts of stored super capacity power and power electronics, to:
- Boosts the battery to drive the reversible alternator at start.
- Support vehicle electrical voltage at start.

So an ultracap gives the starter a kick while keeping electronics from dimming, but also helps capture more energy from regenerative braking. See also:
