- The check automotive is called after three record-setting Renault prototypes from the final century
- Renault claims the largely 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 enhancing electric-vehicle effectivity.
The Renault Filante Report 2025 is a single-seat EV that shall be utilized in effectivity and vary document makes an attempt later this yr, Renault stated in a press launch. First, it will likely be displayed on the Retromobile traditional automotive present in Paris, which runs Feb. 5-9, alongside vehicles that impressed it.
Renault has an extended historical past of record-setting prototypes. The Filante Report 2025 takes its title from three of them: the Ètoile Filante (French for “capturing star”) that set velocity information at Utah’s Bonneville Salt Flats within the Nineteen Fifties, and the 40 CV des Data and Nervasport des Data that set numerous velocity and endurance information within the Twenties and Thirties, respectively.

The open-wheel bodywork, spherical headlights, and cab-rearward proportions are retro homages to these historic document vehicles, notably the 40 CV des Data. That is thematically in step with Renault’s present road-car technique which, as demonstrated with the Renault 5 E-Tech hatchback, does 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 elements have full fairings like these of a land-speed document streamliner. The motive force sits in a reclined place much like that of a System 1 race automotive, with the steering wheel hooked up to the cockpit cover for simpler ingress and egress.
Physique panels are held along with seen screws, a alternative impressed by plane development that helps save weight, in keeping with Renault. The panels themselves are carbon fiber, whereas the chassis is comprised of a mixture 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 cut back weight right 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, underneath the driving force’s ft). Equally, steer-by-wire and brake-by-wire methods helped designers profit from the restricted house within the Filante Report 2025’s cockpit.
Renault did not present a lot element on the powertrain, however stated the Filante Report 2025 will roll on specially-designed Michelin tires with a slim design to assist cut back aerodynamic drag and rolling resistance.
As a one-off prototype designed to flee the weight-and-efficiency spiral of present EVs aiming for information, the Filante Report 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 highway journey from Stuttgart, Germany, to the Silverstone racetrack within the U.Ok.—with sufficient cost leftover for just a few victory laps. However the place the EQXX no less than vaguely resembled a highway automotive, with 4 doorways and a standard inside, the Filante Report 2025 appears tailor-made for racetracks.
