With over 1,000 km driven without recharging at an average speed of 102 km/h, the Renault Filante Record 2025 sets a new record for electric efficiency.
The consumption measured by Renault was 7.8 kWh/100 km, a figure obtained under conditions close to actual highway usage.
The Filante Record 2025 is equipped with an 87 kWh battery, similar to that of the Scénic E-Tech electric. At the end of the attempt, the battery still showed 11% available charge, corresponding to over 120 km of additional range at speeds above 100 km/h. The test was conducted at the UTAC circuit in Morocco, under stable weather conditions, following an initial attempt that was canceled in France due to bad weather.
Designed as a rolling laboratory, the vehicle weighs approximately 1,000 kg. This lightweight construction results from extensive use of composite materials, aluminum alloys, and 3D printed parts, combined with a topological optimization aimed at reducing mass without compromising rigidity. The Filante also features fully electronic steering and braking systems (“steer by wire” and “brake by wire”), allowing for a more compact architecture and weight savings.
She still has some power left.
Aerodynamics was a central focus of the development. Wind tunnel tests conducted in spring 2025 led to significant design changes aimed at reducing drag. The wheel fairings, for instance, were redesigned and attached directly to the wheels to enhance airflow. Air inlets and outlets were minimized to the strict necessity, while the central cell, already close to aerodynamic optimum, was largely retained.
Three drivers took turns at the wheel over a total duration of 9 hours and 52 minutes, covering 239 laps of a circuit just over 4 km long. Beyond the numeric performance, this record illustrates the combined impact of aerodynamics, weight management, and the efficiency of systems on the consumption of an electric vehicle.
