Renault Filante Record 2025 Achieves 1,008 km Without Recharging

Renault reports that its Filante Record 2025 demo car covered over 1,000 km at motorway speeds without recharging, highlighting advances in electric efficiency.

Renault closed 2025 with a strong engineering statement by setting a new electric efficiency record. The Filante Record 2025 demo car covered 1,008 kilometres in less than ten hours without recharging, maintaining an average speed of around 102 km/h — a pace comparable to sustained motorway driving.

The record run took place on 18 December at the UTAC test track in Morocco. Over 9 hours and 52 minutes, excluding driver changes, the vehicle delivered an average energy consumption of just 7.8 kWh per 100 km. Crucially, Filante Record 2025 used an 87 kWh battery, the same capacity as the one found in the production Scenic E-Tech electric. At the finish line, 11% of the battery remained, enough for an additional estimated 120 kilometres at speeds above 100 km/h.

From the outset, Renault made it clear that the objective was not to maximise range at any cost. The car was neither fitted with an oversized battery nor driven at extremely low speeds. Instead, the challenge was to demonstrate that long-distance electric driving is achievable under realistic conditions, combining high cruising speeds, technical stops and multiple drivers.

Aerodynamics proved decisive. Weighing around 1,000 kg, Filante Record 2025 underwent significant redesign following wind-tunnel tests earlier in the year. Engineers reworked the wheel fairings, reduced air intakes and refined key interface areas to eliminate unnecessary drag. These changes played a major role in unlocking the car’s exceptional efficiency.

The demo car also served as a rolling laboratory for advanced technologies, including fully electronic steer-by-wire and brake-by-wire systems, extensive use of ultra-light materials such as carbon fibre and 3D-printed aluminium components, and bespoke Michelin tyres developed specifically for low rolling resistance.

Filante Record 2025 is deeply rooted in Renault’s heritage. Its design and philosophy reference historic record-breaking models such as the 40 CV des Records of the 1920s and the gas-turbine-powered Étoile Filante of 1956. Like its predecessors, the car was never intended for production but conceived as an engineering statement of its era.

Renault emphasises that the project goes far beyond a single record. The data and insights gathered — particularly in aerodynamics, lightweight construction and energy efficiency — are expected to influence future road-going electric models. The achievement suggests that high-efficiency, long-distance motorway driving may be possible without increasing battery size.

The human and technical story behind the record will be explored further in an upcoming three-episode mini-series, documenting the development process, the challenges faced by the teams and the final record attempt in Morocco.
