- Kia EV4 winter test confirms stable charging and efficient winter range in -37?C conditions.
- EV4 GT-line achieved peak charging power and strong cabin performance in extreme cold.
On February 19, Kia confirmed that the Kia EV4 winter test delivered strong results during Tekniikan Maailma?s 2026 winter evaluation in Finland. Conducted in extreme cold conditions ranging from -29?C to -37?C, the assessment examined winter range performance, charging stability, energy efficiency, and cabin comfort. The results demonstrated that the EV4 maintained operational reliability and consistent performance despite harsh Nordic temperatures, reinforcing its capability as a long-range battery electric passenger car designed for challenging climates.
Performance in Extreme Cold Conditions
The Kia EV4 winter test focused on real-world operation under sub-zero stress scenarios. The EV4 GT-line variant, equipped with an 81.4-kWh long-range battery, delivered a winter driving range of 261 kilometres compared to its 584-kilometre WLTP rating. Among the ten vehicles evaluated, this represented the closest correlation to the official rating, highlighting strong winter range performance in extreme cold conditions.
Energy Efficiency Under Sub-Zero Temperatures
Despite operating in temperatures as low as -37?C, the EV4 GT-line recorded the second-lowest energy consumption in the test group. This outcome reflects optimized thermal management and battery conditioning strategies that supported stable energy output and minimized efficiency losses typically associated with severe winter climates.
Charging Stability and Peak Power Delivery
A key highlight of the Kia EV4 winter test was its ability to maintain stable DC fast charging behavior under freezing conditions. The vehicle reached its claimed peak charging power of 128 kW, making it one of only two vehicles in the evaluation to achieve declared maximum charging capacity.
Consistent Fast Charging at -30?C
Fast-charging performance at approximately -30?C remained comparable to summer conditions. The EV4 completed a 20?80% DC fast charging session in 30 minutes, delivering 51.4 kWh at an average charging power of 105 kW. This consistency under extreme cold conditions demonstrates the effectiveness of battery preconditioning and thermal regulation systems integrated into the platform.
Cabin Comfort and System Reliability
In addition to drivetrain and charging metrics, the Kia EV4 winter test also emphasized stable cabin comfort in harsh winter environments. The vehicle maintained interior heating performance without excessive impact on overall efficiency, supporting occupant comfort while preserving winter range performance. These results position the EV4 GT-line as a resilient electric passenger car capable of operating reliably in demanding Nordic climates.
