Marcelis designed the concept model of the Twingo, which was originally released in 1993, using her signature colour palette of translucent pastel hues.
The electric car's exterior is coloured in a semi-transparent matte white hue, while the interior features a translucent steering wheel in a nod to the designer's work in resin.
Marcelis's prototype reprises some of the Twingo's "most recognisable" features, Renault said.
These include the car's single-volume silhouette, characteristic "frog-eye" headlights and modular interior.
"My challenge was to elevate them without losing their unique identity," Marcelis said. "To bring all elements into a more luxurious realm, activated by light and materiality."
Her redesign also aims to draw attention to the car's details.
"It's a bit like an inside-out car, where the exterior is stripped of colour so that just the different translucencies of the PMMA [plexiglass] could be experienced," the designer told Dezeen.
"It allows you to see structural details when viewed from certain angles. It's being very honest to the way the car is produced – celebrating all details instead of hiding them."
Marcelis looked at the "interplay between colours and materials" when designing the Twingo, which has a completely white chassis and all-white wheels.
Inside, a warm raspberry hue was used for the dashboard and headliner, with seats and other soft parts of the car clad in a red fabric shot through with purple threads.
"The interior is very saturated in colour and stripped to the essentials, simplifying many elements into singular objects – like the sunshade and rearview mirror which are combined into a single element and the front seats are also merged into a single bench," Marcelis said.
"The choice of burgundy is an elevated use of the original Twingo red."
"The colour also evokes a cosy feeling – making the experience of being inside the car one of comfort and luxury," the designer added.
"The tactile experience of the interior is very important to the concept. Each material used inside has a different tactility and surface texture."
The translucent peach-coloured steering wheel was designed to be both aesthetically pleasing and still functional.
Marcelis described it as "a single disk with all the functionings of a steering wheel, whose shape reveals itself further when light catches the edges."
"By keeping the body thin but the edges a bit thicker, a nice grip for the hand is created and the saturation of colour intensifies towards the outer edges where it is thicker," she added.
The reimagined Twingo, which was unveiled at the Centre Pompidou in Paris, was retrofitted with an electric motor to symbolise Renault's "commitment to electric cars", with the company aiming to make all of its cars across Europe electric by 2030.
Renault has previously created a concept car with French designer Matthieu Lehanneur that saw him turn the Renault 4L into a nomadic hotel suite. This model was also retrofitted with an electric motor.
A recent Dezeen feature looked at how cars will begin to look "dramatically different" as electric vehicles become the norm.
