- The check automotive is known as after three record-setting Renault prototypes from the final century
- Renault claims the principally carbon-fiber prototype weighs lower than 2,204 kilos
- Many of the weight is from an 87-kwh capability battery pack
Renault on Thursday unveiled an idea automotive designed not simply to look fairly on auto present stands, however to check new methods of bettering electric-vehicle effectivity.
The Renault Filante File 2025 is a single-seat EV that can be utilized in effectivity and vary document makes an attempt later this 12 months, Renault stated in a press launch. First, it is going to be displayed on the Retromobile basic automotive present in Paris, which runs Feb. 5-9, alongside automobiles that impressed it.
Renault has an extended historical past of record-setting prototypes. The Filante File 2025 takes its title from three of them: the Ètoile Filante (French for “taking pictures star”) that set pace data at Utah’s Bonneville Salt Flats within the Fifties, and the 40 CV des Information and Nervasport des Information that set numerous pace and endurance data within the Twenties and Nineteen Thirties, respectively.

The open-wheel bodywork, spherical headlights, and cab-rearward proportions are retro homages to these historic document automobiles, significantly the 40 CV des Information. That is thematically according to Renault’s present road-car technique which, as demonstrated with the Renault 5 E-Tech hatchback, would not shrink back from retro styling.
The design continues to be wind-tunnel confirmed, Renault claims. The elongated form helps higher management airflow across the physique, and the wheels and suspension parts have full fairings like these of a land-speed document streamliner. The driving force sits in a reclined place much like that of a System 1 race automotive, with the steering wheel connected to the cockpit cover for simpler ingress and egress.
Physique panels are held along with seen screws, a selection impressed by plane building that helps save weight, in response to Renault. The panels themselves are carbon fiber, whereas the chassis is comprised of a mix of aluminum, carbon fiber, and metal. Topology optimization—the usage of software program fashions to find out the minimal quantity of fabric wanted in a given space—helped additional scale back weight all the way down to what Renault claims is lower than 2,204 kilos.

The battery pack accounts for 1,322 kilos of that complete. It has the identical 87-kwh capability because the pack within the Renault Scénic E-Tech crossover, however with cell-to-pack tech the automaker claims reduces weight and permits for extra versatile packaging (the pack is positioned ahead within the chassis, beneath the driving force’s toes). Equally, steer-by-wire and brake-by-wire programs helped designers profit from the restricted area within the Filante File 2025’s cockpit.
Renault did not present a lot element on the powertrain, however stated the Filante File 2025 will roll on specially-designed Michelin tires with a slim design to assist scale back aerodynamic drag and rolling resistance.
As a one-off prototype designed to flee the weight-and-efficiency spiral of present EVs aiming for data, the Filante File 2025 is comparable in intent to the Mercedes-Benz Imaginative and prescient EQXX idea, which in 2022 managed 746 miles on a single cost on a street journey from Stuttgart, Germany, to the Silverstone racetrack within the U.Ok.—with sufficient cost leftover for a couple of victory laps. However the place the EQXX no less than vaguely resembled a street automotive, with 4 doorways and a traditional inside, the Filante File 2025 appears tailor-made for racetracks.
