The Demers FXP 174 is a groundbreaking Type I ambulance designed for progressive, forward-thinking departments across municipal, hospital-based, private EMS, and fire services. Purpose-built from the ground up, it blends advanced technology with ergonomic design to protect crews, support patients, and drive performance in the most demanding environments.

Inside the 174” x 95” module, a clinical layout shaped by real-world feedback delivers the space, visibility, and flow providers need. Every feature is designed with provider wellbeing in mind, reducing fatigue and streamlining workflow so medics can focus on delivering confident, timely care.

At the heart of the FXP 174 are the FX Action Seats, a first-of-its-kind seating innovation explicitly engineered for first responders. Featuring one-click 4-point seatbelts, these seats allow medics to remain safely buckled while stabilizing themselves with their legs, freeing their hands for patient care. Positioned near the stretcher and key equipment, they minimize strain and reduce risk while enhancing mobility and access. With an emergency lock tested to withstand 26G acceleration and integrated belt sensors for driver awareness, FX Action Seats represent the next level of safety integration in EMS design.

The FXP 174 also introduces a fresh approach to configuration and layout. An ultrawide electric passthru window improves visibility while reducing noise. Linear lighting with adjustable intensity and color adapts to the needs of both patient and crew. A door-forward design and functional storage solutions maximize space efficiency, keeping equipment within reach and helping providers stay seated and focused on patient care. Add the dual HVAC ducted diffusion system, plus a range of optional enhancements, and you have a workspace designed for comfort, clarity, and control.

More than just an ambulance, the FXP 174 reflects Demers’ drive to push boundaries. It embodies innovation, ergonomic design, and safety integration in every detail. These qualities have made us a trusted partner to EMS for generations.
