What is The Striker Volterra ARFF Vehicle?

The Striker Volterra ARFF is an EV ARFF vehicle and was developed to meet the increasing calls for environmentally conscious solutions at airports of all sizes around the world. Utilizing a powerful combination of onboard batteries and a diesel engine, the vehicle is designed to reduce emissions which protects the environment, improves firefighter safety, and offers a lower cost of ownership through reduced fuel consumption and engine maintenance. The result is an emergency response vehicle that can operate primarily in fully electric mode but has an electric emergency response mode that provides an uncompromised approach to firefighting and emergency response at an airport.

Most daily operations can be completely run on battery power, but an automatic switch to the diesel engine if the situation requires ensures operation and performance remains uninterrupted when it’s needed most. The Striker Volterra ARFF vehicle is built on traditional Striker ARFF platform configurations allowing for fleet continuity and smooth training and maintenance processes.

What are the Benefits of the Striker Volterra ARFF Vehicle?

Airports around the world continue to implement initiatives directed toward reducing pollution. Electric vehicle innovations have been vital to the ability to meet sustainability goals without impacting operations or the safety of the traveling public. The Striker Volterra ARFF vehicle is an innovation which uses industry-leading Oshkosh patented technology for fire truck electrification and operation.

Capabilities and benefits include:

  • Reduced Emissions - An Oshkosh patented electric drivetrain featuring an electro-mechanical infinitely variable transmission (EMIVT) allows zero-emissions operation and stand-by mode when powered by the onboard batteries.
  • Improved Firefighter Safety - Reduced emissions and engine noise reduce firefighters’ exposure to air toxins and sound pollution generated from a standard diesel drivetrain, lessening the impact on their health.
  • Lower Total Cost of Ownership - There is up to a 40% reduction in fuel consumption and a reduced need for engine maintenance, creating cost savings for the department.
  • Continuous Readiness - The onboard batteries can be coupled to the internal combustion engine to provide continuous and uninterrupted power to the pumping system or drive systems.
  • Faster Acceleration - Setting a new standard for rapid response time performance, the Striker Volterra ARFF’s EV mode activates automatically when needed for acceleration and to maintain the batteries for maximum readiness. Reaching 0-50 mph (0-80 kph) in 25 seconds, the Striker Volterra ARFF accelerates 28% faster than traditional diesel-powered ARFF vehicles which typically reach 50 mph (80 kph) in 32 seconds.
  • Unaltered Performance - No matter the state of the battery, the performance and operation of the vehicle is never altered.
  • Regenerative Braking - This feature increases efficiency and reduces brake wear by converting the vehicle’s kinetic energy to electricity, which recharges the batteries, and reduces brake temperature and wear.

Why is There Demand for Low-Emissions ARFFs?

Striker Volterra ARFF at Birmingham AirportReduced and zero emissions vehicles have become increasingly popular in recent years as consumers, businesses, and governments become more conscious of their impact on the environment. The Striker Volterra ARFF vehicle leverages the latest advancements of EV technology, giving airports and their fire departments a solution that helps them meet environmental goals and protects firefighters, while providing exceptional and uncompromised capabilities for emergency response.

Environmental Initiatives and Regulations - According to a 2020 report from the International Council on Clean Transportation (ICCT), airports in the United States, China, and the European Union are major drivers of commercial flight carbon emissions. Governments in the United States, United Kingdom, and worldwide, continue to develop and enforce new environmental initiatives and regulations that seek to protect air quality and reduce carbon footprints. For example, the Federal Aviation Administration’s airport sustainability program encourages sustainable airport planning with the reduction of environmental impacts a core tenet of the program.

As regulatory environments continue to evolve and change, the Striker Volterra ARFF vehicle provides airports a tool to help them meet local and national environmental and sustainability goals.

Cost Savings - Fuel is a significant cost for airports and airport fire departments alike, and prices have been trending higher for several years. Electric vehicles offer potential fuel cost savings over traditional diesel drivetrain vehicles by lowering the amount of fuel consumed. Additional cost saving can be realized with fewer required preventative engine maintenance and repairs. The smaller diesel engine consumes less oil and fluid, while standby mode eliminates wear from idling.   

Health and Safety - The health and safety of firefighters is the top priority for manufacturers and departments alike.  Low-emissions ARFFs can help mitigate and even eliminate exposure to diesel emissions when being run completely on battery power.  The Striker Volterra ARFF vehicle will utilize the on-board batteries when entering and exiting the firehouse, creating a zero-emissions environment and helping to protect the firefighters.

Charging Requirements for the Striker Volterra ARFF Vehicle

Striker Volterra ARFF Vehicle at the Manchester AirportOne of the top considerations for electric vehicles is how the batteries are charged. Most EV drivetrains require a power source that connects the onboard batteries to the power grid. The Striker Volterra ARFF stands out from the rest of the industry because connecting to the power grid is not required for it to maintain a state of charge when the batteries are coupled with the diesel engine. As long as fuel is available, performance will not be degraded.

Plugging in the batteries may be the most efficient charging option for some departments, and the Striker Volterra ARFF can charge from the standard 220 or 480 electrical grid. The Striker Volterra ARFF is not dependent on a specialized charging infrastructure. Customers may opt is to install 480V 3-phase at 32 amps to support the Striker Volterra ARFF’s charging needs. ARFF vehicles typically do not experience the same volume of calls for service that a municipal apparatus does, so the need for fast charging, and the related expense, is a less critical consideration. If fast charging is important to the department, infrastructure investment would be a part of the planning process. Additionally, chargers could be integrated with renewable energy sources such as wind and solar, achieving further emission reduction.

How Does Emergency Response Change with an Electric Vehicle?

Ensuring uncompromised response to emergencies is vital to supporting firefighters and their critical mission to save lives. The Striker Volterra ARFF vehicle is fully tested and compliant to all NFPA 414 and ICAO standards.

NFPA 414 requires ARFF vehicles meet a two-hour full rated discharge requirement. A fully electric vehicle requires a very large amount of energy in order to meet this requirement. Once the power is depleted, the battery needs to be recharged, or a range extending energy source such as a combustion engine must be used. 

In contrast, the Striker Volterra ARFF vehicle can continue to operate at full performance with respect to driving and pumping. The firefighter does not need to react or adjust to a reduction in performance based on the battery’s state of charge, making the two-hour pump discharge requirement much easier to achieve.

The Striker Volterra ARFF’s Uncompromised Performance:

Rapid Response - 0-50 mph (0-80 kph) in 25 seconds. The vehicle can achieve 28% improved acceleration when fully loaded, resulting in a quickened response time.

Pump and Roll - Utilizing 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.

Stationary Pumping - Utilizing the internal combustion engine to efficiently power the water pump, the vehicle’s Command Zone Control System optimizes engine RPM based on water pump requirements to reduce emissions and noise.

Operation of the Striker Volterra ARFF is virtually identical to traditional Striker ARFFs with a diesel drivetrain, eliminating the need for additional operator training and ensuring superior response:
