Renault switches to turbo mode in electric mobility
Renault throws down the (electric) gauntlet to Volkswagen and Toyota: With its new, comprehensive electric mobility concept, the French carmaker is moving into the fast lane - technologically as well as strategically.

The most important pillars of Renault's new e-strategy are a comprehensive model offensive, the new electric industrial pole "Renault ElectriCity" in northern France, the E-Powertrain MegaFactory in Normandy, the strategic partnership with Envision AESC to build a battery gigafactory in Douai, and a joint project to develop sustainable batteries with the French start-up Verkor. In addition, there are new developments in the field of e-powertrain and comprehensive battery lifecycle management.

Renault Group plans to launch ten new all-electric models by 2025. This will give the company the most sustainable model range in Europe, with an E share of over 65 per cent. This includes the new Renault 5 and an iconic small car model currently referred to as "4ever". An all-electric edition of the Alpine sports car will follow from 2024.

The central technological component of the new vehicles is an innovative motor concept: Renault is the first OEM to develop its own e-motor, which does not require permanent magnets and thus no rare earths. The motor is based on electrically excited synchronous motor (EESM) technology. From 2024, Renault plans to introduce further technological improvements; the goals are higher efficiency and lower costs. 

Renault Group has also agreed a partnership with French start-up Whylot for an innovative axial flow E-motor. This technology will initially be used on hybrid powertrains to cut costs by 5% while reducing CO2 emissions by up to 2.5 grams per kilometre under WLTP. Renault Group will be the first manufacturer to produce the axial flow E-engine on a large scale from 2025.

In the field of power electronics, Renault will extend its control over the value chain by integrating the inverter, DC-DC converter and on-board charger (OBC) into a box of its own production. With a compact design, this "one-box" project will be 800-volt compliant. Since it can be deployed across all platforms and powertrains (BEV, HEV,
