Stellantis to extend the life of its diesel engines with new improvements

Stellantis is going through a difficult time, to say the least. Their plans to electrify their entire range have not gone as planned and this has led to a large part of the route hours of their brands being modified. Thus, we are seeing how some of their engineers are updating the STLA Small platform that, initially, was going to be exclusively for electric vehicles. But this has not been the only setback that they have had to tackle in all the technical departments that they have spread across their different brands.

This "problem" we are talking about is nothing more or less than extend the life of your diesel engines through a series of technical improvements that will optimize its performance and efficiency. In a context where the automotive industry is moving towards electrification, the company seeks to offer solutions that allow these traditional engines to remain competitive. The objective is to adapt diesel engines to the new regulations without reducing their reliability ensuring that they remain a viable option for consumers which still depend on this type of propulsion.

Optimizing performance and reducing emissions…

One of the key aspects that Stellantis is working on is combustion optimization. to make the engines more efficientThis would include improvements in thermal management, tweaks to fuel injection and advanced emissions reduction systems. The company is also researching new technologies that minimize environmental impact. of these engines, as more filters efficient and the use of alternative fuels that reduce the carbon footprint.

According to the information the engine 1.5 BlueHDi 130 HP (DV5) It was due to be withdrawn from the market this year 2025. But everything indicates that it will undergo a major overhaul to remain in operation until 2030. And thanks to its technical update, the Stellantis factory in Metz-Trémery (France) will continue to have a workload since it has been assembled there since 2017. In this way, they will get around the Euro 7 standard that will come into force for passenger cars and industrial vehicles as of November 29, 2026.

The second diesel engine that will be updated to remain active will be the four-cylinder 2.2 turbodiesel B.B2 of origin Fiat, manufactured in Pratola Serra (Italy) and named MultiJet by the Italian manufacturer. This engine was a development for its medium and large-sized commercial aircraft such as the Fiat Ducato, Peugeot Boxer, Opel Vivaro, etc. Well, this engine would not only be updated to comply with Euro 7 but could also be adapted to new mid-size models within the Stellantis group.

Improved durability for longer life…

Stellantis seeks to extend the longevity of its diesel engines with more resistant materials and systems that reduce the wear of its parts. This would allow diesel vehicles to maintain their performance for longer, diminishing the need for frequent maintenance. Focus on durability is key to convince consumers that diesel engines are still a reliable option and profitable long term.

Strategy to stay in the market…

With all these improvements, Stellantis aims to maintain its presence in the diesel segment. As the market continues to evolve towards electrification, the consortium is aware that, although electric mobility is booming, there is still a large user base that needs combustion engines. efficient and durable. This digital workplace strategy will allow offer viable options while the gradual transition to cleaner technologies takes place.

In the end, the departure of Carlos Tavares will be a "breath of fresh air" and a gift for the Euro-American group. We will be Keep an eye on all Stellantis' moves in updating its diesel engines. If we're being fair, these types of engines are still a modern, efficient and sustainable option in today's automotive landscape. Especially for those who still drive a lot of miles a day and can't (or don't want to) rely on a plug. Or not?
