Volvo B9TL
The Volvo B9TL is a low-floor double-decker bus built by Volvo from 2002 until 2018. It superseded the Volvo Super Olympian and the Volvo B7TL. The 2-axle version has been superseded by the Volvo B5TL in 2014 and the 3-axle version has been superseded by the Volvo B8L in 2018.
The Volvo B9TL chassis shared the same design of the Volvo B7TL. The key difference from both its predecessors, the Volvo Super Olympian and Volvo B7TL, was a new 9.3-litre engine originally designed by Renault Trucks, now a subsidiary of Volvo. The radiator was located at the rear offside, similar to the smaller B7TL. The front module design was shared with other low-floor bus chassis built by Volvo, and independent suspension is fitted at the front axle (replaced by conventional front suspension after some years of production).
The B9TL was initially offered in three-axle format, and the two-axle variant was added in 2006 to replace the B7TL. The driveline comprises a Volvo D9A Euro III engine (rated at 300 hp or 340 hp), which was later replaced by the Volvo D9B Euro IV/V/EEV engine (using selective catalytic reduction technology; two versions were offered - the D9B260 rated at 260 hp for two-axle version, and a higher powered D9B310, rated at 310 hp, for three-axle version), and coupled to ZF 5-speed or 6-speed automatic gearbox. Volvo also offered the Voith four-speed gearbox as an alternative gearbox option.
A Volvo B9TL prototype with a Volgren CR223LD body was delivered to Hong Kong in July 2003 for Kowloon Motor Bus (KMB) as a demonstrator for the Eco-Driveline concept. It was put into service in April 2004 and registered as MF5119.
In early 2004, a Volvo B9TL prototype with a facelifted version of the TransBus Enviro500 body arrived in Hong Kong and registered as LU3721. It had a slightly different front and rear design, and its rear route number box was moved beneath the upper deck rear window. After TransBus International was renamed Alexander Dennis in May 2004, it became the only TransBus Enviro-series bus with a non-Dennis chassis as well as the only facelifted version of the Enviro500 to be manufactured during this period.
Later in the same year, a Wright-bodied B9TL prototype was also delivered. The rear design of its Wright body differed from that of the Wright-bodied Volvo Super Olympian, with the number plate positioned beneath (and slightly to the right of) the rear route box.
In 2005, KMB ordered 63 B9TL chassis with Wright bodywork and 50 with Enviro500 Mark 2 bodies. The Wright-bodied buses entered service between 2005 and 2006, and the Enviro500 Mark 2 bodied buses entered service in late 2006/2007. These were followed by another 35 buses with Enviro500 Mark 2 bodywork, which entered service in 2007/2008. All Enviro500 Mark 2-bodied B9TLs were retired on 13 September 2025.
In 2009, KMB ordered 60 Wright Eclipse Gemini 2 bodied B9TLs, quickly followed by another 115, they have begun delivery as of early 2010. These were followed by an order for a further 115 Wright-bodied B9TLs in 2010. All these buses entered service between 2010 and 2012.
