The rear design of its Wright body was different from that of the Wright-bodied Volvo Super Olympian, with the number plate moved beneath (and a little to the right of) the rear route box. Later in the same year, a Wright-bodied B9TL prototype was also delivered. 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. It had a slightly different front and rear design, and its rear route box was moved beneath the upper deck rear window. In early 2004, a Volvo B9TL prototype with a facelifted version of the TransBus Enviro500 body arrived in Hong Kong. It was put into service in April 2004 and registered as MF5119. Kowloon Motor Bus' Gemilang-bodied Volvo B9TL on its first day of serviceĪ 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. Asia Pacific Hong Kong Kowloon Motor Bus This is fully explained that they have originally being expecting for a version to Berlin before they getting the final result that showed fail at the end. But since both sides are point out there have Difficulties in Mechanical Configuration, the B9TL version with MAN engine has been completely shelved permanently. There were rumours that the Euro III version B9TL that was once planned to being equipped with a German made MAN D2866 series engines with Voith DIWA 864.3E gearbox for Berlin. The front wheels of the three-axle B9TL are usually supplied by Alcoa, but some buses (including the three prototypes) had all their wheels supplied by Alcoa. Volvo also offered the Voith four-speed gearbox as an alternative gearbox option. The driveline comprises a Volvo D9A Euro III engine (rated at 300 bhp or 340 bhp), 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 bhp for two-axle version, and a higher powered D9B310, rated at 310 bhp, for three-axle version), and coupled to a ZF 5/6-speed gearbox. The B9TL was initially offered in three-axle format, and the two-axle variant was added in 2006 to replace the 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 radiator was located at the rear offside, similar to the smaller B7TL. The key difference from both its predecessor, the Volvo Super Olympian and Volvo B7TL, was a new 9.3-litre engine originally designed by Renault. The Volvo B9TL chassis shared the same design of the Volvo B7TL.
