Millions of cars on the road today in Europe bear Gilles Le Borgne's imprint. Before being named head of engineering at Renault Group in 2020, he held a similar post at PSA Group, now part of Stellantis, where he worked for three decades. Le Borgne has taken on even more responsibility at Renault since February, when he was named chief technology officer. Le Borgne, a two-time Automotive News Europe Eurostar winner, recently spoke with ANE Associate Publisher and Editor Luca Ciferri and News Editor Peter Sigal about his most pressing challenge: How to improve the efficiency of electric cars so they are more affordable and sustainable.
