Product

Electric Vehicle Kit (EVK)

  • The EVK can replace the combustion powertrain in any UTV — including MRZR-class light tactical vehicles — with a bolt-on, bolt-off electric powertrain.
  • The EVK can augment combustion UTVs — adding energy storage and high-power export while maintaining combustion drive.
  • The EVK can be installed as a series hybrid, with the electric motor driving the wheels and the combustion engine acting as a range extender.

Why electric

Quiet when it counts. Power at the edge. Range when you need it.

A combustion UTV announces itself — engine noise and heat that can be heard and seen long before the vehicle arrives. The EVK enhances the UTV — near-silent movement, up to 15 kW of power export, instant acceleration, around one-fifth the thermal signature of combustion, and far fewer moving parts to maintain.

Range is the usual objection to electric tactical vehicles. The EVK answers it two ways: a modular battery sized to the mission, and an optional range-extender generator — so you decide how much of the mission runs silent.

What is in the kit

Everything needed for propulsion

Motor, inverter, battery, thermal management, controls and harness — designed, built and integrated as one system, so nothing on the propulsion side is left for you to source.

  1. Modular battery pack

    Mounted low in the chassis for a low centre of gravity. Capacity is set by the configuration you choose.

  2. High-voltage harness

    Cabling routed from the pack to the inverter and motor, built for the vehicle it goes into.

  3. Inverter and controls

    Drives the motor from the battery and manages the system.

  4. Electric motor

    35 lb, with 165 hp peak and 162 lb-ft peak torque in the reference build.

  5. Belt drive and reduction

    Connects the motor to the vehicle’s driveline on a machined mounting plate.

Also in the kit

  • Thermal management

    Keeps the pack, motor and electronics in their operating window.

  • Range-extender generator (optional)

    Recharges the battery to extend range beyond the pack.

Configure

Choose how much of the mission runs silent

The EVK battery is modular. Trade battery against generator run time to hit the weight, silent range and total range your mission needs — then send us the configuration.

Balanced

Enough battery for a silent approach and time on station, with the generator for the drive out and back.

Silent on battery; audible when the generator runs

A relative comparison. Actual range and weight depend on the vehicle, terrain, payload and duty cycle — we size them to your mission.

Special operations demonstrations

SPM has demonstrated vehicle-integrated silent power export to special operations forces on MRZR-class light tactical vehicles.

Tactical vehicle industry engagement

Presented alongside the defense mobility community, including TEVCON, with running prototype hardware rather than renderings.

Backed for dual-use

Venture-backed specifically to accelerate dual-use military and civilian electric off-road powertrains.
