On the day of the test, it happened to be right after a heavy snowfall in Harbin, and the snowy roads as well as the ice surface near Sun Island provided good site conditions for the test. It also offered KW17 sufficient room for performance. In the comprehensive road test conducted first, compared with the vehicles equipped with regular tires which were very cautious, the vehicles equipped with winter tires showed excellent handling. Later, whether it was slalom or cornering, due to the unique human foot mechanics design of KW17, the vehicle was more stable when turning, and its maneuverability was greatly improved compared with ordinary tires. The strong grip and low noise brought by KW17 created a quiet and comfortable driving experience, which fully demonstrated its advantages as a winter tire designed for high-end sedans. In the subsequent ice acceleration and emergency stop tests, when the vehicles equipped with regular tires finally managed to start after slipping, the vehicles equipped with winter tires had already driven dozens of meters away steadily. When both vehicles were traveling at a speed of 40 kilometers per hour and began emergency braking from the same position, the central bar pattern design improved the high-speed braking and traction performance of KW17, making its braking performance about 25% higher than that of general tires. Therefore, the vehicle could brake smoothly within a very short distance, while the vehicle equipped with regular tires not only had a much longer braking distance, but also experienced fishtailing.
