The largest diesel engine plant in the world, the Stellantis plant in Trémery, in Moselle (57), is in full transition and has been producing 100% electric engines for a year.
Inaugurated in 1979, the Stellantis plant in Trémery (PSA Powertrain before the merger of the French group with FCA) near Metz, in Moselle (57), is a production site for the engines of the Stellantis group. Since its creation, more than 50 million heat engines which were produced there: the 3-cylinder “EB” petrol units (alias 1.2 PureTech) are notably manufactured there, but also the 4-cylinder “DV5” and “DW” Diesel (1.5 and 2.0 HDi), allowing it to be the world’s largest diesel engine plant.
But since the end of 2019, something new has changed the daily life of this factory: it is now responsible for producing a new electric motorization called e-GMP, a unit which equips the 100% electric models of the Group’s brands, such as the Peugeot e-208 for example, and which represented less than 10% of the site’s production in 2020.
Electric motor production: 2021, a pivotal year
But 2021 is about to become a pivotal year for this production of “made in France” electric motors: around 180,000 units should roll off the Trémery lines this year, reaching a rate of 900,000 units per year by 2025. Indeed , vehicle electrification is accelerating, leading to the gradual disappearance of diesel engines.
And even if the uncertainties about the success of these new 100% electric vehicles persist, against a backdrop of an unprecedented health crisis, the newly created Stellantis group has promised not to close any factories. What to protect the employment of 3,000 employees of Trémery.
Diesel gives way to electric
And the vehicles of the Stellantis group are far from being an isolated case: indeed, this year, around twenty models will be offered without a Diesel engine, whether at Volkswagen, Renault, Dacia, Nissan or Honda, according to the institute. IHS Markit, for whom 2021 marks “an unprecedented turn”.
At Renault, we are already planning a total disappearance of Diesel by 2025 for passenger cars, and the diamond has also started a similar energy transition at its engine plant in Cléon, in Seine-Maritime.
Last September in Europe, registrations of electrified cars exceeded those of Diesel for the first time, according to JATO. But they represent only 8% of total vehicle sales, their price still being prohibitive while the recharging infrastructure is not yet sufficiently developed.
