Allison Transmission and Chinese bus manufacturer Zhongtong Bus Holding Co., Ltd. joined forces to deliver 211 CNG city buses to Yerevan. The new vehicles are equipped with Allison T270R transmissions and will provide commuters in Armenia’s capital with a greener, more convenient and comfortable way to travel.
Due to their environmental friendliness and lower noise compared to buses with diesel engines, natural gas buses fit best in the intensely populated metropolis like Yerevan. Catering for inner city traffic, this 8-meter-long low-entry vehicle is the product of Zhongtong’s sophisticated bus making platform and meets the operational needs of Yerevan’s public transport.
The bus model has 25 seats and is rated for 60 passengers. Powered by a 200hp Weichai CNG engine and an Allison T270R fully automatic transmission with gross input torque 900Nm, the bus complies with Euro V pollutant emission standards. The transmission also features 6 forward speeds, 1 reverse and an integral retarder which extends the life of the brakes and lowers maintenance costs.
“Allison’s fully automatic transmission has Allison’s patented Continuous Power Technology™, which delivers smoother, seamless shifts providing superior passenger comfort, ” said Zhang Zhengwei, Director of Zhongtong Bus North China. “Its torque converter technology multiplies engine torque to significantly improve startability and launch, resulting in higher operational productivity which maximizes the benefits of a natural gas engine.”
“Allison’s products offer high reliability, stability, greater fuel economy and easier control of the bus that greatly reduce driver’s stress. Allison Automatics are ideal for city buses in heavy traffic conditions,” added Zhang.
“The partnership between Zhongtong and Allison began in 2007 and the two sides have established a sustainable relationship for more than a decade. Allison is the world’s largest manufacturer of fully automatic transmissions for commercial vehicles, with a large global sales and service network. We will continue to provide high quality products and services to Zhongtong,” said David Wu, General Manager of Allison Transmission China.
