In Hailar, where temperatures plummet to -40°C, the land is locked in ice, winds cut like knives, and every inch of ground freezes as hard as rock. This is the “polar proving ground” that pushes vehicles to their limits—and the ultimate stage to demonstrate genuine hardcore strength.
Recently, the full product matrix of Foton Cavan gathered in this frozen realm for a head‑to‑head battle against bitter cold. Four model lines — Cavan Letu, Cavan BEACON Heavy Duty Truck, Cavan Lefu, and Cavan Ledi — took on the challenge. They performed calmly across core tests including low‑temperature charging, range and energy consumption, cabin heating, and ice‑snow handling, fully verifying their reliability, economy, and safety in frigid conditions.
Cavan Letu: Uncompromised Range, All-Rounder for Cold-Climate Operations
Cavan Letu directly targets the core pain points of winter operation, solving low‑temperature range anxiety with robust performance, perfectly meeting the strict demands of diverse scenarios including cold‑chain transportation.
In low‑temperature charging efficiency tests, supported by the intelligent pre‑heating technology of the Battery Management System (BMS), the vehicle boasts an “anti‑freeze superpower”. It completes a full charge from 20% to 100% in just 40 minutes — far exceeding the industry average — ending long waits for winter recharging.
Against the harshness of extreme low temperatures, Cavan Letu excelled in maintaining battery activity, energy recovery efficiency, and cabin insulation, perfectly balancing winter reliability and economy.
Meanwhile, its intelligent thermal management system, high‑efficiency energy recovery, low‑rolling‑resistance tires, and optimized aerodynamics maximized energy efficiency.
In low‑temperature adaptability tests, power output remained strong and stable. The liquid thermal heating rate of the power battery performed exceptionally; even at -40°C, it easily met speed demands of 105–110 km/h, with a stable range of 170–200 km, completely breaking free from cold‑weather performance limitations.
Cavan Lefu: Warm Cabin + Stable Control, Guarding Safety and Comfort
Cavan Lefu focuses on occupant comfort and driving safety in extreme cold, creating a mobile “winter warm cabin” and “safety fortress” through thoughtful design.
In winter heating tests, its high‑efficiency diesel heater proved extremely effective: it raised cabin temperature from -30°C to a comfortable 20°C in only 15–20 minutes — nearly 30% faster than pure electric heating — and steadily maintained an ideal 18–22°C. Occupants quickly enjoy warmth amid piercing winds, with simple and flexible operation.
By using diesel heating instead of pure electric heating, Cavan Lefu achieved improved range, successfully resolving the conflict between cabin heating and power consumption.
In ice‑snow handling tests, the VDC Vehicle Dynamic Control System delivered outstanding stability:
- On low‑friction surfaces, the vehicle accelerated smoothly without skidding, swung wide, or losing control;
- The ABS anti‑lock braking system brought the vehicle to a stable stop from 50 km/h on split‑friction icy roads, with no deviation or slippage;
- The TCS Traction Control System ensured steady starts on slopes with low grip, remaining stable and controlled.
Together, they provide all‑around protection for driving in snow and ice.
Cavan Ledi: Low Energy Consumption & Fast Charging, Impressive Hardcore Performance
Cavan Ledi demonstrated industry‑leading capabilities in charging efficiency and energy consumption control under extreme cold.
It is fully compatible with national standard DC chargers, with a battery cycle life exceeding 4,000 cycles and supporting 2C fast charging. During charging from 20% to 100%, charging efficiency, SOC curves, and thermal management operated with clockwork precision, reflecting reliable quality.
To verify low‑temperature energy use, Cavan Ledi completed fully loaded tests at temperatures from -20°C to -40°C under urban, highway, and combined cycles, with the cabin air conditioning maintained at 20°C throughout.
Real‑world data delivered strong results:
- Extreme cold urban cycle: 73.51 km driven (average 35.6 km/h), consuming 24.6 kWh
- Extreme cold suburban cycle: 104.5 km driven (average 62.3 km/h), consuming 34.6 kWh
Its low energy consumption ranks among the top in the industry.
In braking performance, Cavan Ledi achieved millisecond‑level response time, paired with low‑drag dual‑cylinder calipers. Even on slippery icy surfaces, its braking distance outperformed competitors, delivering strong, stable stopping power and a solid safety foundation for cold‑weather travel.
Cavan BEACON Heavy Duty Truck: Dual-Energy Electric & Hydrogen, Intelligent Heavy Truck Leader in Extreme Cold
As the flagship model built on the world’s first purpose‑developed “dual‑energy native platform” supporting both battery electric and hydrogen fuel cells, Cavan BEACON features the industry’s pioneering “1+3+2” cross‑domain integrated EE architecture. It passed rigorous tests focused on low‑temperature stability, efficiency, and vehicle thermal management.
On low‑friction ice and snow, Cavan BEACON moved with precision and poise: no skidding during start, acceleration, or climbing; responsive steering and braking; and stable, accurate body control.
The three core electrical systems underwent thorough low‑temperature calibration and maintained full performance in frigid conditions. Battery charging/discharging speed, e‑axle efficiency, and power output remained uncompromised, ensuring consistent range, power, and recharging performance.
For cabin comfort and safety, an advanced vehicle thermal management system enabled fast heating and precise temperature control, quickly clearing frost and fog for clear vision while keeping occupants warm. It intelligently coordinated heat distribution between the cabin, battery, and motor, ensuring stable operation of core electrical components in low temperatures.
Conclusion
From ultra‑fast low‑temperature charging and precise range and energy control, to rapid cabin heating and stable ice‑snow handling, the full Foton Cavan product matrix excelled in every key dimension: range, handling, safety, power, and economy.
In real‑world -40°C testing, Cavan Letu, Cavan BEACON, Cavan Lefu, and Cavan Ledi all passed extreme trials with outstanding performance.
They not only validated their reliability in the harshest environments but also built strong confid
