Hyundai ST1 Electric Ambulance Specifications - Official

The Hyundai ST1, originally launched as a purpose-built electric light commercial vehicle, has rapidly evolved into a critical platform for specialized emergency medical services. Built on a dedicated skateboard chassis, the ST1 electric ambulance represents a significant leap from traditional internal combustion engine (ICE) based emergency vehicles, offering zero tailpipe emissions, near-silent operation, and a stable low-center-of-gravity platform that enhances patient comfort during transit.

This article provides the official technical specifications for the ST1 electric ambulance, focusing on three critical areas: dimensional and weight parameters, powertrain and battery specifics, and the medical compartment configuration. For procurement teams and fleet managers evaluating this Korean platform against domestic Chinese alternatives, this guide offers a direct comparison baseline.

Key Dimensions and Weight

The ST1 ambulance configuration is based on the standard ST1 cargo van architecture, with specific modifications to the rear body to accommodate the patient compartment. The key exterior dimensions are as follows:

• Overall Length: 5,595 mm
• Overall Width (excluding mirrors): 2,030 mm
• Overall Height (with roof-mounted emergency light bar): 2,640 mm
• Wheelbase: 3,450 mm
• Front Overhang: 890 mm
• Rear Overhang: 1,255 mm

The extended wheelbase provides exceptional interior volume, crucial for the medical team to work efficiently. The curb weight of the base ST1 van is approximately 2,150 kg. In the ambulance conversion, depending on the level of medical equipment installed (including the stretcher system, defibrillator, infusion pumps, and oxygen supply racks), the gross vehicle weight rating (GVWR) is set at 3,500 kg. This leaves a usable payload capacity of roughly 800 kg for crew (typically 2-3 attendants) and the patient, which is adequate for standard emergency response scenarios but slightly less than comparable diesel-powered Type II ambulances on the market.

The interior cargo length available for the medical module is 2,900 mm, with an interior width of 1,750 mm and an interior height of 1,600 mm. This allows for a standard 1,900 mm long powered stretcher to be loaded longitudinally with sufficient clearance for a paramedic to stand upright.

Powertrain and Battery Details

The ST1 electric ambulance is powered by a single permanent magnet synchronous motor, a configuration now standard across modern electric light commercial vehicles.

• Motor Type: Permanent Magnet Synchronous Motor (PMSM)
• Maximum Power Output: 160 kW (approximately 218 PS)
• Maximum Torque: 310 Nm
• Drive Configuration: Front-wheel drive (FWD)

The power delivery is smooth and linear, a critical attribute in emergency driving where sudden torque spikes can destabilize a patient on a stretcher. The top speed is electronically limited to 130 km/h, ensuring safe high-speed freeway operation.

Battery specifications are central to the operational viability of an emergency vehicle. The ST1 utilizes a high-voltage lithium-ion polymer battery pack:

• Battery Capacity: 76.1 kWh (usable)
• Battery Chemistry: Lithium-ion Polymer (Li-Po)
• Thermal Management: Active Liquid Cooling/Heating system
• Onboard Charger: 11 kW AC (standard), 350 kW DC fast-charging capability (10-80% in approximately 45 minutes)

Regarding range, it is critical to distinguish between the standard WLTP cycle and real-world ambulance duty cycles. In the standard WLTP combined cycle, the ST1 van platform is rated for approximately 320 km. However, for the ambulance conversion, the EPA range estimate is significantly lower due to the added weight of the medical module, constant auxiliary power draw (lighting, HVAC, medical devices), and the aggressive acceleration profiles often used in emergency response. The official EPA-estimated range for the ST1 ambulance configuration is 250 km under mixed urban/highway conditions. In a high-intensity urban response scenario with continuous use of the cabin HVAC system set to 22°C, the practical range drops to approximately 180 km. This necessitates strategic route planning and access to a robust charging network, particularly for hospitals serving as primary dispatch hubs.

For fleet managers comparing this to domestic Chinese alternatives, the Sinotruk Howo (重汽豪沃) electric light truck chassis, widely used for emergency vehicle conversions in the Chinese market, offers a comparable battery package. The Howo electric chassis typically features a 100 kWh-class LFP (Lithium Iron Phosphate) battery pack, which provides a similar operational range for city-based emergency responses. While the ST1 offers superior driving dynamics and a lower floor height for easier patient loading, the Howo chassis provides a simpler, more cost-effective service and parts network for domestic Chinese operators. Both platforms face the same fundamental challenge: balancing battery weight against payload and ensuring sufficient reserve range for multi-call shifts.

Medical Compartment Features

The medical compartment is where the ST1 differentiates itself from standard commercial van conversions. Hyundai, in partnership with certified ambulance upfitters, has engineered the rear module to meet specific emergency medical service (EMS) standards, including the European CEN 1789 standard for road ambulances.

Key features of the medical compartment include:

• Patient Litter System: A powered hydraulic stretcher system with a load capacity of 250 kg. The anchoring system is integrated directly into the vehicle’s structural rails, ensuring safety during high-speed maneuvers.
• Seating Configuration: A forward-facing attendant seat (swivel type) and a side-facing secondary seat, both equipped with 3-point seatbelts and energy-absorbing headrests.
• Climate Control: A dedicated auxiliary HVAC system for the patient compartment, independent from the driver’s cabin. This is a 24V DC system powered by a secondary 12V auxiliary battery, which is automatically recharged by the high-voltage traction battery via a DC-DC converter. The system is designed to maintain a temperature range of 18°C to 28°C even with the rear doors frequently opened.
• Electrical System: The vehicle is pre-wired for 12V and 24V medical equipment. Standard outlets include multiple 12V sockets and two 230V (or 110V) pure sine wave inverters rated at 1,500W each, sufficient for powering ventilators, suction units, and infusion pumps.
• Lighting: Full LED lighting package, including a dimmable examination light at the head of the stretcher and a scene work light at the rear loading area.
• Storage: High-density polyethylene (HDPE) cabinetry with pneumatic struts, designed for easy sanitation and secure storage of medical supplies. The cabinets are designed to hold standard-sized drug boxes and intubation kits.
• Oxygen Supply: Fixed oxygen supply system with two 10-liter cylinders mounted in a dedicated, crash-tested compartment, with flowmeters and outlets positioned above the patient’s head.

One critical operational feature is the Cold Chain and Power Take-Off (PTO) Options. For advanced life support (ALS) units that must carry blood products or certain medications, the ST1 can be specified with an integrated medical refrigerator. This unit operates on the 24V electrical system and maintains a constant 4°C. Crucially, the ST1 allows for Vehicle-to-Load (V2L) functionality, enabling the high-voltage battery to power external equipment, such as mobile field hospitals or additional refrigeration units, during extended standby operations. This PTO capability is a distinct advantage over many ICE vehicles, which require the engine to remain idling to generate sufficient auxiliary power.

Summary for Fleet Decision-Makers

The Hyundai ST1 electric ambulance offers a sophisticated, high-tech solution for urban and suburban EMS fleets looking to decarbonize. Its official specifications—a 160 kW motor, 76.1 kWh battery, and a 250 km EPA range—place it as a leading electric platform in the light commercial ambulance segment. The integration of the medical compartment with the vehicle’s electrical architecture, particularly the V2L and cold chain options, demonstrates a mature understanding of emergency medical requirements.

However, procurement teams must weigh the initial acquisition cost against the total cost of ownership. While charging infrastructure remains a logistical hurdle for ²⁴⁄₇ operations, the lower energy cost per kilometer and reduced brake maintenance (due to regenerative braking) offer significant long-term savings. For those considering domestic alternatives, the Sinotruk Howo electric light truck chassis provides a pragmatic entry point into electric emergency fleets with similar battery capacity and a far more extensive domestic service network.
