Renault's new demo car drives over 1,000 km at highway speeds on a single charge

The Renault Filante Record 2025 electric demo car managed to drive more than 621 miles (1,000km) on a single charge, while keeping an average speed of 63mph (102km).

The bold demo car looks a little like the Batmobile, but there’s a lot more to this all-electric than its good looks.

The Renault Filante Record 2025 pays tribute to the record-breaking 40 CV that was released 100 years ago.

Much like the car it pays homage to, the Renault demo car has now earned itself a record of its own.

The Renault Filante Record 2025 spent almost 10 hours at an average speed of around 63mph

The Renault Filante Record 2025 is finished in a striking ultraviolet blue color and features a bold design with a protective bubble over the centrally-positioned cockpit that gives it a Formula One-inspired look. 

The car was built using ultra-light materials, including carbon fiber and 3D printed elements, and has boosted aerodynamics to make it as efficient as possible. 

However, despite its appearances, the Filante Record 2025 is powered by a ‘regular’ 87kWh battery, like the kind you’d find inside a Renault Scenic E-Tech EV. 

Renault said it wanted to see if it was possible to push a Scenic-sized EV battery to do 1,000km at realistic highway speeds. 

And, on December 18, it managed it. 

The team headed out to the UTAC test track in Morocco, where they spent less than 10 hours (nine hours and 52 minutes, to be exact) covering 1,008km (about 626 miles) at a consistent average speed of 102km (63mph). 

The carmaker says this challenge shows that ‘this level of range is achievable in motorway-like conditions’. 

”This project was born from an obsession: achieving record-breaking efficiency,” Renault concept car project manager Olivier Blanche said. 

“We battled the weather and aerodynamics, but what stands out most for me is the human adventure: an incredibly motivating collective challenge, driven by the dedication of the Renault teams and all our partners”.

And believe it or not, the demo car still had some more juice in the battery

Even after setting a new benchmark for EV energy consumption at sustained highway speeds, the Renault Filante Record 2025 had a little more left to give. 

At the end of the challenge, the car still had 11 percent battery remaining. 

In real terms, this means the demo car could have traveled an extra 74 miles at a speed of more than 60mph.

So, when it comes to EV range tech, it seems as though Renault could be a carmaker to keep your eye on.
