The new images reveal a number of subtle changes from the production car, of which UK deliveries will begin in early 2025.
The headlight surrounds, for example, appear to be slightly rounder, and the projectors are now more conventional blocks of LEDs.
A charge indicator features on the bonnet – similar to on the new Renault Twingo concept – with a stylised '5' that gradually fills to indicate the fullness of the battery.
At the rear end, the gap between the upper and lower segments of the brake light is wider than before. The light bar that spanned the full width of the rear end has been replaced with a solid-black trim piece.
Alongside the release of teaser images, the brand also confirmed that the new 5's 52kWh battery yields a range of 248 miles, according to WLTP tests.
The 5 is being developed to be the most fun small electric car to drive, according to Renault boss Luca de Meo and his fellow company executives.
"The Renault 5 is the car that everybody wants. It's a legend that inspired all generations, and everyone is looking forward to it,” de Meo said at the event.
“The final car will be revealed in February at Geneva. I've already test-driven it, and I can't wait to open pre-orders."
