Renault cars have had plastic hatch doors for a long time, which have the added benefit of lowering the vehicle's curb weight. As a bonus, they allowed architects to install outside lighting that spanned the building's width.

Theric, the back hatch door is easier to operate in the new Renault Megane E-TECH Electric. Some metal supports are unnecessary due to a new design and an industrial method employing plastic injection, reducing the number of components.

The final concept was initially implemented in the Eolab prototype, which targeted minimal weight and 1L/100km fuel economy through product design, digital simulations, and plastic injection production engineering.

The new Renault Megane E-new TECH's rear hatch incorporates several innovative technologies that contribute to the car's overall lightweight and hence its improved fuel efficiency (technologies also used by Renault Kangoo Van E-TECH Electric). As a result, two patent applications were filed, and their innovations will be implemented in seven different Renault vehicles, including the brand-new Austral.

We had to rethink the back hatch door's structure because of the common association of plastic with fluid vein innovation. Not an easy task, but with the 2022 Renault Megane E-TECH Electric, we're finally in the lead.

Because of the incorporation of Water Injection Assisted Molding, the overall structure is now more robust. Water is injected into the area to be carved, creating a new method.

The groove's hollow center serves as a reinforcing beam. The water injection technique removes plastic, which is subsequently recycled and utilized in producing new components, lowering the amount of plastic produced.
