ESOX X2

History

The ESOX X2 is an electric unmanned ground vehicle developed by ESOX Group for military evaluation and client pilot programs. ESOX announced completion of the X2 platform in August 2026 and opened it to customer testing.

The vehicle combines four Theron in-wheel electric motors, an 8 kWh solid-state battery pack, and the ESOX OS software layer. Its propulsion system sends torque directly to the wheels and eliminates the conventional gearbox and driveshaft.

The completed X2 weighs 300 kg and has been tested with payloads of up to 300 kg. ESOX describes the vehicle as a modular platform that can be adapted with different sensors, autonomy modes, communications systems, and mission equipment.

Development and pilot program

ESOX Group announced in August 2026 that development of the X2 had been completed and that the vehicle was entering client pilot programs. The program is intended to allow potential users to evaluate the platform under representative operating conditions.

The propulsion architecture was developed around four ESOX Theron motors installed directly at the wheels. According to information published through Autonomy Global, the four motors deliver a combined 1,000 Nm of torque, with 250 Nm available at each wheel. This arrangement removes the gearbox and driveshaft used in conventional centralized drivetrains.

ESOX reported that the current vehicle has been tested with a payload of up to 300 kg. The company projects that further development could increase payload capacity to 600 kg. The higher figure is therefore a development objective rather than a demonstrated capability of the completed pilot configuration.

The company presented the X2 as a configurable platform rather than a single fixed-purpose vehicle. ESOX stated that customers could license the underlying architecture and create mission-specific variants using the company's motors, batteries, electronics, and software.

Design

Propulsion

The X2 uses four Theron in-wheel electric motors. Each motor is rated at 250 Nm of torque in the announced X2 configuration, producing a combined output of 1,000 Nm. Because the motors are located at the wheels, propulsion torque is transmitted directly to each wheel without a conventional gearbox or driveshaft.

The direct-drive arrangement reduces the number of mechanical components between the electric motors and the wheels. ESOX also states that the Theron motors operate quietly and at relatively low temperatures, characteristics intended to reduce the vehicle's acoustic and thermal signatures.

Battery system

The X2 is powered by an 8 kWh ESOX solid-state battery pack consisting of two 4 kWh modules. ESOX states that the pack has approximately twice the energy density of the lithium-ion cells currently used in comparable military electric ground platforms at the same weight. This energy-density claim is a manufacturer statement associated with the pilot platform.

Vehicle architecture and payload

The completed X2 has a vehicle mass of 300 kg. ESOX reports that it has been tested while carrying up to 300 kg of payload. The company has also stated a projected payload capacity of up to 600 kg following further development, but this value has not been presented as a demonstrated capability of the current vehicle.

Software and mission systems

The X2 is integrated with ESOX OS, the company's software layer for vehicle configuration and operation. ESOX states that the system can support digital simulation of vehicle configurations before hardware is assembled.

During operation, the platform can stream telemetry and sensor data and receive over-the-air software updates. The architecture is intended to allow changes to sensor packages, autonomy modes, communications layers, and mission-specific configurations without redesigning the vehicle's core propulsion hardware.

Program status

As of the August 2026 announcement, development of the initial X2 platform had been completed and the vehicle had entered client pilot programs. The available source material describes customer evaluation rather than operational military service or production deployment.

The pilot phase is intended to evaluate characteristics including mobility under load, battery endurance, thermal and acoustic behavior, and the adaptability of the software-defined vehicle architecture. A report published by NXS Media Wire also distinguishes the demonstrated 300 kg payload from ESOX's projected 600 kg future capability.
