Stellantis Resurrects Diesel Across Europe in Dramatic Retreat From Electric Ambitions

Stellantis, the world's fourth-largest automaker, is quietly reintroducing diesel engines across at least seven European car and van models, a strategic about-turn that underscores just how badly the industry's electrification timetable has collided with commercial reality.

The reversal, which began in late 2025 under new chief executive Antonio Filosa, spans models from the Peugeot 308 and DS No. 4 hatchback to a swathe of commercial vehicles including the Opel Combo, Citroën Berlingo and Peugeot Rifter. A newly developed 2.2-litre diesel has already debuted on the Opel Zafira. The company framed the move as demand-led, with a spokesperson confirming that Stellantis had opted to maintain diesel in its portfolio and, in some cases, expand availability.

The timing is pointed. Earlier this month Stellantis disclosed €22.2 billion in charges linked to the wholesale reset of its electrification strategy and product plans, driving an estimated net loss of up to €21 billion for 2025 — the worst in the group's four-year history. The dividend has been suspended, and the board has authorised up to €5 billion in hybrid bond issuances to shore up the balance sheet. European sales fell 3.9 per cent last year, following a 7.3 per cent decline in 2024.

The diesel pivot carries a certain competitive logic. Chinese rivals that dominate the EV segment have virtually no presence in diesel, offering Stellantis a niche where price-sensitive European buyers face limited choice. Diesel's share of EU new car registrations fell to just under eight per cent in 2025 — a fraction of the fifty per cent it commanded before the Dieselgate scandal — but the field is now so depleted that margins may prove more defensible.

Yet the strategy sits uneasily alongside Brussels' CO₂ reduction trajectory. With fleet-wide targets tightening through 2035, expanding diesel availability risks complicating compliance at precisely the moment regulators have offered the industry more flexibility through the Automotive Package. For Stellantis, the bet is that pragmatism will buy time — and revenue — while its longer-term electric portfolio catches up.
