Renault just surprised the EV world with a mind-bending endurance feat. Its experimental Filante Record 2025 electric prototype recently drove over 626 miles (more than 1,000 km) on a single charge using a standard-sized 87 kWh battery — the same capacity found in the production Renault Scenic E-Tech SUV.
Even after nearly 10 hours of sustained highway driving, the car still had about 11 percent of its battery left.
This wasn’t a slow hypermiling test. Renault maintained a realistic average speed of about 63 mph (102 km/h)throughout the run, proving that extreme range doesn’t have to come from oversized packs or trick driving.
The key to this achievement was efficiency engineering, not battery brute force. The Filante’s streamlined body, lightweight construction (around 1,000 kg), ultra-low rolling resistance tires, and advanced systems like steer-by-wire helped it use just around 7.8 kWh per 100 km — roughly equivalent to 8 miles per kilowatt-hour, far better than what today’s production EVs typically achieve.
Renault says insights from this test could influence future production EV designs, pushing the industry toward greater real-world range without bigger batteries.
