Clotilde Delbos will step down as Renault's chief finance officer, she told analysts on Friday, to focus on leading the group's Mobilize unit.
After six years as CFO Delbos will be replaced by Thierry Pieton, her deputy, starting March 1.
"Clotilde Delbos will mainly focus on her role as CEO of the Mobilize brand ... to accelerate its development in the context of the group's transformation," Renault said in a statement.
The Mobilize brand is part of the group's electric vehicle strategy as it seeks to achieve carbon neutrality in Europe by 2040.
Delbos, 55, was appointed as Renault CFO in April 2016, having joined as group controller in 2012. She also served as interim CEO at the French automaker after Carlos Ghosn was ousted amid a financial scandal and before the appointment of Luca de Meo in June 2020.
Even before the COVID-19 pandemic upended the car industry, Renault was struggling to adjust to life without Ghosn, the architect and longtime boss of its alliance with Japan's Nissan.
Ghosn was arrested in Japan in November 2018 on financial misconduct charges, which he denied, and later fled.
Delbos was name a Eurostar by Automotive News Europe last year for providing stability at Renault during two difficult years. She was key in developing the group’s 2 billion euro savings plan in early 2020. She won her first ANE Eurostar award in 2018.
