- The take a look at automobile is called 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 automobile 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 will probably be utilized in effectivity and vary document makes an attempt later this yr, Renault mentioned in a press launch. First, will probably be displayed on the Retromobile basic automobile 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 identify from three of them: the Ètoile Filante (French for “taking pictures star”) that set velocity data at Utah’s Bonneville Salt Flats within the Fifties, and the 40 CV des Data and Nervasport des Data that set numerous velocity and endurance data within the Nineteen Twenties and Thirties, respectively.

The open-wheel bodywork, spherical headlights, and cab-rearward proportions are retro homages to these historic document vehicles, significantly the 40 CV des Data. That is thematically per 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 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 automobile, 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, based on Renault. The panels themselves are carbon fiber, whereas the chassis is comprised of a mixture of aluminum, carbon fiber, and metal. Topology optimization—using software program fashions to find out the minimal quantity of fabric wanted in a given space—helped additional cut 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 whole. 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, below the driving force’s toes). 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 mentioned 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 data, the Filante Report 2025 is analogous 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.Okay.—with sufficient cost leftover for a couple of victory laps. However the place the EQXX at the least vaguely resembled a street automobile, with 4 doorways and a traditional inside, the Filante Report 2025 appears tailor-made for racetracks.
