Striker Volterra Hybrid Electric Vehicle Capabilities

- Fully tested and compliant to NFPA 414 and ICAO standards

- An Oshkosh patented hybrid-electric drivetrain featuring an electro-mechanical infinitely variable transmission allows zero-emissions operation when powered by the integrated onboard batteries, and can be coupled to the internal combustion engine to provide continuous and uninterrupted power to the pumping system or drive system

- Faster acceleration: setting a new standard for performance, the Striker Volterra is capable of achieving 28% improved acceleration when fully loaded, resulting in a quickened response time

- Idle reduction for up to one hour of zero-emissions standby using onboard energy storage

- Zero-emission driving during entry and exit of the fire station using onboard energy storage

- Available Plug-In Hybrid Electric Vehicle (PHEV) options for further electric vehicle driving capabilities










EV Drive

Electric vehicle (EV) drive mode is a groundbreaking innovation that allows firefighters to operate their ARFF truck in full-electric mode. Automatically engaged, this drive mode lets drivers perform day-to-day non-emergency operations emissions free.


Oshkosh Standy Mode



During standby mode, the vehicle operates at zero emissions utilizing on-board batteries. Providing comfort and power to required systems. The engine starts as needed to maintain battery readiness.

Hybrid Acceleration

The vehicle automatically shifts to Hybrid Mode as needed for acceleration, and to maintain the batteries for maximum readiness. The internal combustion engine and batteries work together to maximize performance and improve response time, while reducing emissions. The Striker Volterra 6x6 ARFF can go 0-50 mph (0-80 km/h) in 25 seconds. Improving acceleration by 28% when fully loaded.


Oshkosh Regenerative Braking


Regenerative Braking

Regenerative braking increases efficiency and reduces brake wear. The vehicles kinetic energy is converted to electricity, recharging the batteries, and reducing brake temperature and wear.


Oshkosh Pump and Roll


Pump and Roll

Pump and roll utilizes both the engine and the battery. The advanced powertrain continuously powers the pump while the driver’s input is smoothly applied to the vehicle’s motion just like every Striker ARFF.


Oshkosh stationary pumping


Stationary Pumping

Stationary pumping utilizes the internal combustion engine to efficiently power the water pump. The Command Zone Control System optimizes engine RPM based on water pump requirements to reduce emissions and noise.
