Renault Filante Record 2025 Raises The Efficiency Bar For Electric Cars - CleanTechnica

The Renault Filante Record 2025 is an experimental electric car designed to push the boundaries of efficiency rather than speed, reflecting a shift in automotive priorities toward intelligent travel distance. Drawing on Renault’s extensive experience in Formula One racing since 1977, where aerodynamic efficiency is meticulously optimized, the Filante Record leverages advanced design techniques and materials to minimize energy consumption. The project involved close collaboration with Ligier for vehicle construction and Michelin for ultra-low rolling resistance tires, emphasizing real-world testing of technical choices on energy use. A key focus of the Filante Record 2025 is weight reduction, inspired by Colin Chapman’s philosophy of “simplify then add lightness.” With batteries constituting over half the vehicle’s mass, Renault aimed to keep the car’s weight around 1,000 kg (2,204 lb) using carbon fiber, composites, and optimized structures. Aerodynamic efficiency was also critical, measured by the SCx value (frontal area times drag coefficient). Initial wind tunnel tests
