Engineering Excellence
Compact Format,
Zero Compromise on Safety
The Model S brings full Pro Line Heavy certification credentials and operational features into the most space-efficient packaging in the range, without sacrificing any structural integrity or safety performance.
Thermal Runaway Containment
Fully certified containment of thermal runaway events in battery assemblies up to 50 kWh. Heat-insulated walls with non-combustible Altilium® CP blanket prevent propagation and keep the exterior below 100 °C.
HF Gas Filtration
Integrated hydrogen fluoride filtration neutralises toxic off-gas emissions during thermal runaway events, ensuring compliance with IMDG and ADR ventilation standards across all transport modes.
Forklift Accessible
Four-way forklift pocket integration and lifting ring enable efficient one-person handling at all stages of the logistics chain from factory floor loading to port container stuffing and airfreight ramp operations.
Stackable Design
Precision-engineered corner castings allow verified stacking in ISO container and warehouse environments, maximising volumetric efficiency and reducing per-unit shipping cost.
