E11 Pro, the flagship battery electric bus from Yutong Bus (SHA: 600066), demonstrated its unrivaled safety and performance under extreme heat and wind conditions in an endurance test a week ago, putting the world's leading EV solution to the ultimate test under extremely challenging conditions.

In response to public concerns about the safety of EV batteries in scorching conditions and worries about range and energy efficiency, Yutong Bus E11 Pro initiated two high-temperature performance tests.

Starting with an interior temperature of 53.6°C, the bus’s advanced climate control system quickly cooled the cabin to a comfortable temperature of 23.6°C in just 27 minutes. During the 113-kilometer round trip, the bus consumed only 0.74 kWh/km, highlighting the advanced capabilities of the vehicle even in extreme heat conditions.

The E11 PRO boasts a developed energy-efficient all-electric climate control system. The state-of-the-art air conditioning unit provides 38,000 kcal/h of cooling capacity, increasing cooling capacity in response to rising outside temperatures.

A specially developed air curtain solution creates an air seal for the middle door when it is opened, preventing hot air from entering and cold air from escaping, further reducing energy consumption.

The vehicle body is made of dark gray, fully enclosed hollow glass panels, and the design provides exceptional thermal management and noise reduction. Yutong's safe battery, based on the proprietary YESS battery protection solution, has a multi-layer fire-resistant and heat-insulating structure that can withstand temperatures up to 1,300 °C for two hours.

The bus is equipped with an advanced liquid cooling system that doubles the cooling speed of natural cooling, combined with anti-condensation and dirt protection, making it adaptable to both high temperatures and dusty road conditions.

From braving frigid temperatures in Kazakhstan and Norway earlier this year to the scorching heat in Saudi Arabia, Yutong buses have successfully demonstrated their reliability in temperatures ranging from nearly 100°C.

Yutong focuses on customized new energy solutions that meet diverse local needs, a strategy that aligns with the country’s sustainability goals outlined in Saudi Arabia’s Saudi Vision 2030. In recent years, Yutong Bus has operated a fleet of over 4,000 buses in Saudi Arabia, a success largely attributed to the impressive performance and reliability of its vehicles across its product range.
