Stellantis is developing a new 1.6-liter diesel engine designed to meet Euro 7 standards. This move aims to extend the lifespan of diesel models amid a slowdown in electric vehicle demand.

Initially, the plan was to upgrade the 1.5 BlueHDi to Euro 7 and produce it until 2030, but that idea has been abandoned. The new engine will replace both the French 1.5 BlueHDi and some current units from the Multijet family.

A key feature is hybridization. The diesel is set to be paired with a six-speed eDCT6 dual-clutch automated gearbox, which integrates an electric motor with 20 or 28 horsepower and a 48-volt battery. This setup is already used in Peugeot's gasoline hybrids and allows for short-distance electric driving.

The new powertrain is expected to debut in 2026 models, but it won't first appear in the Alfa Romeo Tonale. Potential launch candidates include the new DS №7 or Lancia Gamma.

Stellantis points out that corporate clients and fleets continue to show steady demand for diesel. For them, range and fuel efficiency are crucial, making these more economical vehicles appealing even as environmental regulations tighten.
