In the midst of the transition to electric cars, Stellantis seems to be reviewing its powertrain priorities. After several years of decline for diesel engines in Europe, Rumors are circulating about a possible return of this technology, but this time in a hybrid version.
Diesel: a technology still in demand
Despite the growing popularity of electric motors, diesel engines are still popular, especially for long-distance travel. In Europe, an estimated 1.3 million vehicles are still fitted with diesel engines, a proportion that remains significant in markets such as commercial vehicles and premium SUVs. Heavy-duty drivers, in particular, continue to prefer this technology for its fuel efficiency and relatively low running costs.
In this context, Stellantis hasn't totally abandoned the idea of diesel. In accordance with to the latest rumorsin early 2025, the Group has confirmed the relaunch of diesel engine production, particularly for models such as the Citroën C5 Aircross and Peugeot 308. These engines will be equipped with the latest Euro 7 standards, which impose strict requirements on pollutant emissions.
Hybrid diesel: the technology of the future?
That's where the new rumor that has surfaced in recent weeks comes in. According to several sources, Stellantis could consider relaunching not only traditional diesel engines, but also a hybrid version of these engines. Unlike conventional diesel engines, the diesel hybrid combines a diesel-powered internal combustion engine with an electric motor, reducing fuel consumption and CO2 emissions while delivering enhanced performance.
Should this option be confirmed, it would mark a turning point for Stellantis, which, unlike some of its competitors, has no diesel hybrid engines in its range.German competitors such as BMW, Audi and Mercedes. The latter have already successfully launched hybrid diesel models, notably on SUVs and top-of-the-range cars. UPDATE: In the past, PSA has introduced Hybrid4 diesel engines for the 3008, 508 and DS5.
Why a hybrid diesel engine?
The case for a hybrid diesel engine seems pretty clear. On the one hand, it would enable Stellantis to meet the stringent requirements of European emissions regulations, while at the same time offering an alternative to the diesel engine. for customers who do not yet have access to a sufficient recharging infrastructure for 100 % electric vehicles. On the other hand, a diesel hybrid engine could particularly appeal to customers of SUVs and top-of-the-range sedans, segments in which the Stellantis Group wishes to strengthen its position, particularly with its Alfa Romeo brands.
If Stellantis decides to launch a diesel hybrid, it could represent a real alternative for heavy-duty customers. We'll have to wait for official announcements to find out whether this rumor will materialize, but the fact that the Group is exploring this avenue testifies to its willingness to adapt its offerings to the changing needs of the market.

Obviously they'll take their hdi rather than a far too reliable JTDm.
The 2.0 HDi is surely one of the most reliable diesel engines of the last 20 years. That's what I explained in another article. FORD, Mazda, Toyota, Suzuki, Volvo etc... Many brands have had it. If Stellantis bets on it, it's far from being a bad idea. For smaller diesels, on the other hand, I'd bet more on FCA blocks. Even for larger-displacement models, FCA offers the 2.2.
Euro 7, on the other hand, scares me. With Euro 6, even the most reliable engines have seen their reputation tarnished by all these new anti-pollution devices. Let's wait and see what happens with 7...
Der HDi ist zuverlässig und sauber. Vielleicht haben sie es mitbekommen, dass PSA der einzige Konzern ohne Probleme war. Diesel- oder Abgasskandal. Sie verstehen?
I wouldn't change my JTDm for anything in the world.
Your article is interesting but not correct. Peugeot had developed a diesel hybrid for the first-generation 508.
hello, i was talking about the current range. i've just clarified. thank you for your kindness.
Doch, das ist korrekt. Auch beim DS5 und 3008 gab es diese Technik.
Your article surprisingly forgets diesel hybrids, which PSA has tried with relative success.
hello, i was talking about the current range. i've just clarified. thank you for your kindness.
Hallo, fahre einen Insignia 2.0 l d Gran Sport mit
170 PS.
Könnte mir eine neue Insignia Limousine mit der
Diesel - Hybridtechnik ohne Stecker vorstellen.
Da würden viele zugreifen wenn das Teil auch 'n
bißchen PS hätte.
Lb. Grüße Heribert der den 3. Insignia fährt !!!
The DS5 and Peugeot 508 were the first diesel hybrids.
Das stimmt so nicht. Der Citroën DS5 kam bereits 2012 auch als Hybrid Diesel daher. Der 2.0 Liter Basisdiesel (163 PS) schaffte es mit dem E-Motor zusammen auf 200 PS und 450 Nm. Ich hatte ihn mal einen ganzen Tag lang getestet, ein echtes Sahneschnittchen.
Gekauft habe ich ihn nicht, weil mir die großen Akkus (es waren damals noch keine Lithium bzw. LiFePo4 Akkus) den Kofferraum zu sehr verkleinerten. Auch eine Anhängerkupplung wäre nicht möglich gewesen laut Händler.
Find out more before writing your articles. Citroën and Peugeot have already released Hybrid Diesel models in 2011. The DS 5 was the first, followed by the 508 RXH.
Citroën was first in its heyday ....

Do we know whether these engines will come from Peugeot or Fiat?
Soweit mir bekannt ist, gab es von Peugeot schon einmal einen Diesel-Hybrid! Und zwar den Peugeot 3008H4, den ich schon seit 10 Jahren fahre. Das ist eine Superkonstellation zwischen Diesel und Elektro. Auch in Bezug Kraft und Verbrauch.
Ansonsten ist so etwas sehr selten zu finden!!!!
I am a true car enthusiast spanning from high revving virtually indestructible Lambretti Design engines to Chevrolet V8s . In 2018 I purchased a new VW Passat TDI (Diesel) sedan (MY17) . This car has covered 148,000 kms with only scheduled maintenance with no mechanical problems. My driving style is firm to hard. We often drive to the city and home 850 -900 kms some times the same day . the diesel fuel usage is usually 4.4 - 4.6 liters / 100 kms , being a diesel our maintenance costs are very low. This car runs AdBlue which makes the exhaust burn cleaner than many of todays petrol cars . When I compare many friends hybrid four cylinder cars maintenance costs including a battery replacement , the costs are higher than my VW Passat . I find this car can be driven at speed in comfort on a very small budget. I am going to purchase another new Diesel car (2025) . Unfortunately a new VW Passat sedan is NOT available in Australia, The range of a new diesel is very Limited. My new car will be a Turbo Diesel ONLY. Australia needs a larger choice of long distance comfortable diesel Cars
Mercedes bietet Diesel Hybrid (C Klasse, E Klasse, GLC, GLE)
Endlich geht außer Mercedes-Benz ein weiterer Hersteller diesen Weg!!!
Eine gute Basis ist ja mit dem aktuell sparsamsten Diesel am Markt bereits vorhanden, der 1.5 Diesel läuft wirklich gut!
Aus dem Motor bekommt man locker 160ps mit 360nm in der Spitze, eine große und eine kleine Version 125/160ps in Verbindung mit einer passenden Automatik kann da auch Fahrzeuge an die 2000kg bewegen.
Für kleinere Modelle wäre ein neuer Motor um die 1124ccm sinnvoll, entspricht dann der Masterbohrung des 1.5 Diesel als 3zylinder, Leistung dürfte bei ca. 75/90/105ps liegen und ca. 160-250nm bringen, allerdings und ich bin kein Freund von Automatik ist es am sinnvollsten das mit einer der Leistung und dem Fahrzeuggewicht angepassten Getriebeabstufung zu verbauen.
Ich würde sowas definitiv kaufen!!!
Eigentlich braucht man den Dieselmotor nur als Range-Extender. Immer mit niedriger Drehzahl im optimalen Bereich spart Sprit und Schadstoffe. Wenn man ihn normal mit E-Unterstuetzung laufen lässt wird er nicht warm und versifft. Dann nur für Dauerbetrieb und Langstrecke.
Also aus meiner Sicht kann man beim Diesel auf die Hybridversion verzichten...mein mittlerweile fast 10 Jahre alter GOLF 7 2.0 TDI mit 150 PS lässt sich bei vorausschauender Fahrweise und auf der Autobahn mit Tempomat nicht mehr als 120 km/h mit unter 4,5 Litern/100 km bewegen.
Auf Langstrecken mit nur Landstraßen hat er vereinzelt sogar Verbräuche mit knapp unter 4 Litern geschafft...besser geht's vermutlich auch mit Hybrid nicht.
Auf Autobahnen und Landstraßen sicher nicht, aber im Stadtverkehr schon, da lassen sich locker 2 Liter einsparen.
Und bei den extremen CO2 Preisexplosionen, die uns demnächst aufs Auge gedrückt werden, zählt jeder Liter.
Für Taxis, Uber, Kurierdienste und sonstige Vielfahrer mit >50% Stadtverkehr macht der Diesel Hybrid wirklich Sinn.
As the owner of a 2016 DS 5 hybrid diesel, I am pleased that Stelantis is returning to this rather interesting solution, which has not been as successful as expected. However, the consumption of 5 l of GO per 100 km, even on freeways at reasonable speeds, is very interesting. The only drawback was the battery's somewhat limited range, a drawback that has now been resolved as batteries are more powerful.
I think many would be disappointed as the rumours are about a diesel-electric hybrid as seen in locomotives rather than a parallel hybrid. It's not even a diesel engine, more like a diesel generator paired with a pack of batteries and electric motor.
I'd like the 2.2 jtd in my guilia to be a hybrid version...sorry for the psa engine blocks, they're no match for the germans in terms of torque...the latest 1.5 hdi is unreliable....
Hybrid Antriebe sind für Angsthasen die glauben die Battetieteichqeite reicht nicht aus.
Ein E-Auto hat keinen Auspuff.
Hybrid das schlechteste aus beiden Welten.
Ein Verbrenner der zu viel verbraucht und ein schwacher E-Antrieb mit winziger Batterie...
