On all Pierce electric fire trucks, an Oshkosh patented parallel-electric drivetrain featuring an EMIVT allows zero-emissions operation when powered by the integrated onboard batteries.

The electric fire truck chassis will operate independently in either the all-electric, or internal combustion engine modes. The EMIVT leverages either source of power to provide uninterrupted performance in extended emergency operations.

Operating on Electric

  • Batteries used to power the EMIVT for all-electric, zero emission operation.
  • Powered by energy from the grid, the most sufficient source of generated power.
  • Simplified solution allows traditional vehicle accessories to be powered by the EMIVT.

Operating using ICE

  • ICE engagement is automated with seamless transition after batteries have been depleted.
  • EMIVT allows for mechanical couple to the ground on ICE mode.
  • EMIVT’s parallel electric drive is more efficient than a range extender.


Volterra™ Driving Batteries


Volterra™ Driving Diesel



Standardized Pierce pumping configurations, up to 2000 gpm, are driven through the EMVIT and are powered by either the integrated onboard batteries or the internal combustion engine.

The driveline allows for zero emissions during quick attack responses, and has the ability to transition seamlessly to internal combustion power for extended pumping operations.

  • Standard controls and pump panel layout for operation in either mode
  • Energy from either batteries or ICE, power the pump through the EMIVT.
  • A distinct power source solution provides redundancy for transparent and continuous operational confidence.
  • Loss of battery solution does not limit the pumping performance.



A fire station-based, all encompassing vehicle charging infrastructure provides operational readiness for Volterra electric fire trucks.

Charging solutions are tailored to provide an unobtrusive installation necessary for any station. Established nationwide energy experts offer simple, fast charging solutions capable of full electric fire truck recharge in less than 90 minutes.

Pierce Electric Fire Truck Charging in Station




Volterra™ Charging

  • Batteries are located between the cab and pump house providing benefits to the overall vehicle packaging while also contributing to vehicle safety.
  • No consumption of compartment space or limitation of body configuration.
  • Battery center of gravity is below apparatus combined center of gravity for zero compromise on handling and performance.
  • Placed above frame rails providing a highly protected space that will not be influenced by road debris, side or rear vehicle collisions, or approach and departure angles.
