- 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 bettering electric-vehicle effectivity.
The Renault Filante Document 2025 is a single-seat EV that shall be utilized in effectivity and vary report makes an attempt later this 12 months, Renault mentioned in a press launch. First, it will likely 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 Document 2025 takes its title 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 varied velocity and endurance data within the Twenties and Thirties, respectively.

The open-wheel bodywork, spherical headlights, and cab-rearward proportions are retro homages to these historic report automobiles, 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, would not draw back from retro styling.
The design remains 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 report streamliner. The driving 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 selection impressed by plane development that helps save weight, based on Renault. The panels themselves are carbon fiber, whereas the chassis is comprised of a mix 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 scale back weight right 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, underneath the driving force’s ft). Equally, steer-by-wire and brake-by-wire programs helped designers benefit from the restricted area within the Filante Document 2025’s cockpit.
Renault did not present a lot element on the powertrain, however mentioned the Filante Document 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 Document 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.Ok.—with sufficient cost leftover for a number of victory laps. However the place the EQXX not less than vaguely resembled a street automotive, with 4 doorways and a traditional inside, the Filante Document 2025 appears tailor-made for racetracks.
