On February 9, 2026, FAW Hongqi officially announced that the 2026 HS6 PHEV, in its factory-standard condition, completed a 1131.133-kilometer range test without refueling in extreme cold conditions below -20℃, successfully earning the Guinness World Records™ certification for "Longest distance driven by a plug-in hybrid SUV without refueling in low-temperature conditions." This achievement not only sets a new industry benchmark but also marks a qualitative leap in the reliability of Chinese hybrid technology in extreme climates.

This is not a "laboratory miracle," but the practical result of Hongqi's "Honghu Hybrid Platform" systematic engineering:
✅ All-Weather Battery Reliability System
Using modified lithium iron phosphate battery cells, a special electrolyte formula significantly improves lithium-ion migration efficiency at low temperatures, avoiding the "power outage" dilemma of traditional lithium iron phosphate batteries at -20℃.
✅ Multi-Source Coupled Heating System
Plug-in preheating: When charging, priority is given to using grid power to preheat the battery pack through a liquid PTC heater;
Driving self-heating: When there is no external power source, the system activates motor pulse self-heating technology, using high-frequency current generated by the motor windings to make the battery "self-heat";
Engine waste heat recovery: During driving, the system intelligently utilizes engine waste heat to provide heat to the battery and cabin.
✅ Vacuum Insulation + Thermal Management Collaboration
The battery pack casing has built-in vacuum insulation panel material with extremely low thermal conductivity, locking in heat like a "thermos";
The energy recovery system intelligently reduces the recovery intensity at low temperatures to avoid a sudden drop in battery temperature due to braking energy conversion.
This combination of technologies allows the Hongqi HS6 PHEV to maintain a range achievement rate of over 68% in a -20℃ environment, far exceeding the industry average of 50%.

Key Conclusion: Hongqi is currently the only mid-to-large-sized plug-in hybrid SUV that has broken the 1100km mark in officially certified extreme cold range tests. Its technical approach focuses more on "battery optimization + active thermal management," rather than relying on range extenders or simply increasing battery capacity.
Heilongjiang owner @ColdWeatherTraveler (Tested in January 2026):
"Leaving home at -35℃, with the air conditioning set to 27℃, the displayed range dropped from 248km to 117km, which was quite alarming. But the car started and ran, it didn't break down. I drove 300 kilometers to a gas station using it, and the hybrid mode was very stable."
Chongqing owner @MountainCityCommuter (February 2026):
"It's not that cold here in winter. I only need to charge it once a week for my daily commute, and the electricity bill is less than 20 yuan. When driving on the highway in 'intelligent mode,' the fuel consumption is half that of a gasoline car, which is great."
Rational Perspective: The Guinness World Record is under extreme conditions; the range will be reduced in daily use. However, Hongqi's technology makes this "reduction" no longer fatal.
Breaking the "iron batteries are afraid of the cold" prejudice: Lithium iron phosphate batteries are low-cost and have a long lifespan, but poor low-temperature performance is a common industry consensus. Hongqi proves with its technology: it's not the battery that's the problem, but the thermal management system that wasn't up to par.
Vindicating northern users: In the past, northern users buying new energy vehicles had to "rely on the weather," but now there is a long-range plug-in hybrid SUV that can truly withstand -30℃.
A victory for technological independence: 1.5T engine with 45.21% thermal efficiency, 1-speed DHT, self-developed thermal management system – all independently developed by Hongqi, without reliance on overseas technology.
