Electric expertise hub

In 2022, the Cléon plant inaugurated the new production line for the 6AM engine, bringing about the transformation of the site towards electricity.  The first electric motor developed as part of the Renault-Nissan-Mitsubishi Alliance, with a power of 160 kW, will notably equip Megane E-Tech Electric, manufactured by the Douai plant in the ElectriCity division. Cléon thus contributes fully to the group’s mobility electrification strategy. The European Union and the Normandy region contributed 3 million euros to this project.

This new-generation engine is an electrically excited synchronous motor (EESM), a technology Renault has been betting on for 10 years that offers better performance than the permanent magnet engine. The absence of rare earths limits its environmental impact and production costs. More compact and lighter than Zoe’s engine, it has more power (96 and 160 kW) and better torque (300 Nm). It offers all the pleasure of electric driving, including instant acceleration, both dynamic and linear.

E-Mobility Academy

Training is essential when it comes transforming activities at the Cléon factor y towards electricity. To create the E-Mobility Academy, Renault Group has joined forces with five industrial and academic partners* to meet the sector’s need to strengthen skills. The academy will train younger generations and provide more experienced professionals with new knowledge, through a selection of training programs dedicated to electric mobility professions.

Course content is co-developed by all partners. It is divided into three programs, taught across three sites. At the Cléon factory, the campus is dedicated to the production of electric motors and includes a production line for teaching, a first in France.

The E-Mobility Academy champions the Group’s sustainable development and inclusion goals, driven by its new corporate university, the Reknow University.
