China's largest winter auto testing base kicks off extreme cold weather testing season

China's largest winter automobile testing base in Yakeshi City of north China's Inner Mongolia Autonomous Region officially started a extreme cold weather testing season on Sunday.

Carried out on the frozen surface covering an area of over 300 hectares in the Miandu River National Wetland Park at a temperature of over 30 degrees below zero, the testing comprises braking performance, chassis control and low-temperature range durability of cars.

"Through a large amount of testing and debugging during winter, we enable the vehicle's 'brain' to learn how to precisely control its 'limbs,' namely the precise control over the four wheels of a car. This provides drivers with accurate feedback, confidence and a comfortable driving experience," said Dong Xiaofei, a senior engineer of the extreme testing center at the CATARC Automotive Test Center Hulunbuir.

One of the testing subjects is the antilock braking system (ABS) test on icy surfaces. During the test, engineers monitor whether the system can prevent wheel lockup, and maintain steering ability and vehicle stability during emergency braking, while minimizing the braking distance.

"This year, we have launched a project to build an all-season ice and snow testing base for intelligent connected new energy vehicles (NEVs), in striving to make technological breakthroughs in crucial parts of the industrial chain, such as NEV sensors, drive-by-wire chassis and power batteries. This will strengthen China's voice in the field of extreme environment verification. Once the project is completed, it will be the world's largest first-ever indoor ice and snow testing field with the most comprehensive operating conditions, including the snowing scenario," said Liu Dongjian, deputy general manager of the CATARC Automotive Test Center Hulunbuir.

In winter, the weather in Hulunbuir is extremely cold and dry, with temperatures dropping to minus 25 degrees Celsius to minus 33 degrees Celsius.

Iranian President Masoud Pezeshkian said Monday the United States must change its tone and approach toward Iran.

The U.S. reliance on coercion and bullying will only complicate executive processes, Pezeshkian said at a meeting with Pakistan's Chief of Army Staff Field Marshal Syed Asim Munir in Tehran, according to a statement published on the website of the presidential office.

Pezeshkian stressed the need for the United States to remain committed to its obligations toward Iran "based on the (country's) legitimate rights and international regulations."

He appreciated Pakistan's mediation efforts to ensure peace and stability in the region, expressing hope that the objectives stipulated in the U.S.-Iran peace memorandum of understanding (MoU) would be achieved "with the continuation of the wills and joint cooperation."

Munir, for his part, said Pakistan will continue its role as a facilitator and expressed satisfaction with his country's expanding cooperation with Iran.

Heading an official delegation, Munir arrived in Tehran on Monday. Prior to his meeting with Pezeshkian, he met with Iranian Parliament Speaker Mohammad Baqer Qalibaf and Secretary of Iran's Supreme National Security Council Mohsen Rezaei.

On June 18, the United States and Iran signed the MoU, under which the two were scheduled to hold negotiations within a period of 60 days, which ended on Aug 17, to reach a final agreement. However, the talks' fate remains unclear following renewed escalation between the two countries.
