Ensuring complete security for police missions

From marked vehicles to unmarked cars and specialized vehicles, Gruau works closely with the technical teams of the Ministry of the Interior to develop adaptations that meet the technical and security criteria of national police forces. These adaptations address personnel protection, visibility, communication, and equipment carrying capabilities.

Multiple adaptations to meet the diversity of interventions by the national gendarmerie

For the gendarmerie, which operates in rural and peri-urban areas, Gruau adapts the adaptations based on the specific interventions.

Building on a common base, the modularity of the adaptations (audible and visual signaling, anti-break-in and ballistic protection, canine unit integration, connectivity solutions integration, etc.) aims to meet the specific requirements of different missions: patrols, intervention groups, investigative units, canine brigades, and more.


Transforming all types of passenger and commercial vehicles for municipal police

The specific service needs and environmental characteristics of municipal police vary greatly from one city to another.

Gruau transforms multiple models and offers a wide range of approved equipment: light vehicles or intervention vans, incident response vans, canine units, patrol vehicles, signaling equipment, and more. This allows municipal police officers to carry out their missions safely and in compliance with legislation.

Transformations on all manufacturer brands, all passenger and commercial vehicle models, and all powertrains: petrol, hybrid, or electric.

Wide range of equipment: graphics, audible and visual signaling, pre-wiring for radios, storage solutions, reinforced protection, and more.
