On July 21, Yutong T7 Long-March Tour officially kicked off in Lhasa, the well-known holy city with an altitude of 3658 meters. Right before the event, Yutong T7 successfully passed Yamdrok Tso lake (4441 meters above sea level), one of the three holy lakes in Tibet, and Gangbala Mountain, which is 5030 meters above the sea level.
From Lhasa to Yamdrok Tso lake, the one way distance is over 70 km. However, the narrow road is not well maintained and has many bends. Yutong T7, as a high-end bus for official and business use, fully demonstrates its high reliability and safety standards.
According to the bus maker, Yutong T7 adopts 6.0 liter V8 engine made by the US-based GM. With a horsepower of 315 (232 kilowatts) and a torque of 490 N•m, T7 easily climbs an uphill of over 20 kilometers. Moreover, the rotational speed of its engine stays between 1,500 and 2,000 RPM, showing high fuel efficiency level.
Due to the large number of sharp bends on the roads in Tibet, bus drivers are faced with many challenges. Yutong T7 is equipped with Allison 1000 automatic transmission gearbox from US, which boasts well tried technologies and has been widely used on RV chassis. The highly reliable transmission gearbox has not only greatly improved Yutong T7’s safety standards, but it offers more travel comforts for passengers.
Yutong T7 started its Long-March Quality Tour in Beijing in June this year. So far, it has visited Tianjin, Shenyang, Harbin, Hohhot, and Yinchuan, etc. From Xining to Lhasa, T7 drove nearly 72 hours continuously and has successfully conquered a host of challenges posed along the most demanding road in the world.
So far, T7 has successfully passed high altitude test, and high & low temperature. No matter it’s 40 degrees or minus 30 degrees or over 4,000 high above the sea level, Yutong T7 confidently delivers highly reliable performances, reaching an impressive power level, fuel economy, braking capability, and stability. When T7 was in Lhasa, it also passed a number of stringent tests, such as air quality test, controllability test on S-bend, maneuverability test and stability test, etc. In an acceleration test, Yutong increases its speed from 60km/h to 100 km/h in far less than 25.5 seconds.
