Renault and Thales unveil 4 TROOP military vehicle prototype as European carmakers pivot to defence

Context: Europe's defence push

Russia's invasion of Ukraine and the shift in U.S. foreign policy under President Donald Trump have pushed European governments to increase defence investment. Several European defence firms are turning to the auto sector for extra production capacity as orders surge. For carmakers, the pivot offers a way to diversify amid slow electrification, tight emissions rules, and pressure from Chinese competitors.

The 4 TROOP project draws on Renault's industrial know-how and Thales's secure communications technologies to create a vehicle that can be produced quickly at controlled cost, Renault said on Monday.

A civilian platform turned command center

The prototype is a hybrid 4x4 that can operate on all types of terrain. It supports reconnaissance, troop coordination, surveillance of sensitive sites and the deployment of drones and unmanned ground vehicles. Thales has integrated its Combat Digital Platform, which processes large volumes of data, coordinates sensors and provides decision-support tools. The vehicle also uses a Vehicle-to-Load function to power electrical equipment in the field.

This innovation opens the way to a new generation of dual solutions, in which data becomes a performance multiplier, capable of supporting both internal security missions and high-intensity operations.

The 4 TROOP is not a single model but a concept that can be adapted across Renault's range, from SUVs to commercial vehicles, the company indicated.

Production speed and industrial logic

Renault aims to leverage its manufacturing speed. "That's also the advantage of the automotive industry: we don't take 30 years to do something, we'll do it in 12 months," Renault CEO Francois Provost told Reuters last week. The vehicle is designed for rapid production using standardised civilian platforms and a finely tuned supply chain, keeping costs below those of bespoke military platforms. After-sales support from Renault's dealer network will also simplify maintenance for armed forces.

Drones and next steps

Alongside the 4 TROOP, Renault is developing an aerial drone with manufacturer Turgis Gaillard. A first demonstrator is set to fly before the end of this year, and production is planned at Renault's Le Mans plant with a capacity of up to 600 units per month. Renault is also in early-stage work with Belgian military equipment company John Cockerill.
