Experiencing the interior of the All-new Renault Austral is unique thanks to the carefully chosen textures and materials that have been tested at the Renault Technocentre secret laboratories in Guyancourt (greater Paris area). This is where Carla, trained chemist and head of the sensory panel at Renault, works with a team of testers to ensure that materials used on the car interiors are just as they should be.
