Buick Ultimate E7 Undergoes Extreme Cold Testing: Over 1,000km Combined Range
Road test footage of the Buick Ultimate E7, the first SUV under Buick's premium new energy sub-brand Ultimate, during extreme cold testing has been revealed. Equipped with the True Dragon PHEV Pro powertrain, the model achieves a combined cruising range of over 1,000 kilometers at a temperature of minus 20°C.

According to the official statement, to ensure accurate range indication and battery health, the Buick Ultimate E7 is fitted with the n-Tau AI big data algorithm for battery status, aligning the indicated range closely with the actual driving range. Its intelligent temperature control system adjusts the battery's operating temperature zone in real time, preventing low-temperature range attenuation and extending battery life from the source. The model also boasts impressive charging efficiency, taking just 15 minutes to charge from 30% to 80% and adding about 120 kilometers of range. In addition, all variants of the Buick Ultimate E7 come standard with a 6kW external discharge function. Buick's engineers have also conducted multiple rounds of testing and calibration on systems such as anti-lock braking and torque control under extreme cold conditions. For instance, aiming to address issues like wheel lock-up or even reversal during kinetic energy recovery on ice, they have refined and debugged the systems repeatedly for complex driving scenarios on low-adhesion roads, further safeguarding users' winter driving safety.
