According to Italpassion (not reliable, I know) Stellantis is planning to replace the BlueHdi with a new version of the 1.6 MJet, designed to comply with the Euro 7 regulations, and equipped with a 48V mild-hybrid technology. The gearbox will be the eDCT6, not the TCT. First applications could be the DS No7 and the Gamma https://www.italpassion.fr/it/stellante/stellantis-sfida-le-auto-elettriche-con-un-motore-diesel-euro-7-aggiornato/
