Thailand is world"s famous tourist resort. In 2011, nearly 20 million person-time foreign tourists visited Thailand. However, local drivers get used to driving fast, sometimes up to 140km/h, which is dangerous and even causes severe traffic accidents. Yuchai limited the speed into safety zone by virtue of technology to protect the tourists.
Sunlong"s Thailand customer HONGTONG Company, a large-scale local one who purchased 85 tourist buses with Yuchai 6L330-30 engines in 2011, is responsible for local tourism transport. The company owns a total of 155 Sunlong buses equipped with Yuchai 6L330-30, 6L330-20 and 4G180-20 engines.
In July 2012, Thailand HONGTONG Company requested Yuchai office to limit the 85 buses with Yuchai 6L330-30 engines to 120km/h. Yuchai office responded actively to meet the customer"s requirement. From July 13th, all the buses were downloaded the speed limit procedure and Yuchai guaranteed the safe speed in Thailand market.
