The Volvo B8L is a low-floor double-decker city bus chassis built by Volvo Buses since 2016. It is the intended successor of the Volvo B9TL still currently in production. Two known prototypes are known to have been produced; the other currently operating in Hong Kong with Kowloon Motor Bus.
The B8L model designation indicates its (Bus chassis, 8-litre engine, Low floor) configuration. The bus will enter revenue service in the near future.
The Volvo B8L was conceived as the Euro VI (“Euro 6”) successor to the highly popular tri-axle Volvo B9TL which had been in production since 2002, an evolutionary step in line with rigorous emission standards within Europe.
Volvo’s new range of Euro VI-compliant diesel engines, the 5.1-litre Volvo D5K and 7.7-litre Volvo D8K, were launched in 2013 and found their way into new bus models, such as the Volvo B5TL (diesel) and Volvo B5LH (diesel-hybrid) double-deck city buses, and the Volvo B8R (coach) and Volvo B8RLE (low-entry) single deck buses. Volvo Buses would subsequently release more models of buses would to further strengthen their model offering in line for the Euro VI adoption.
However, in Asia (and particularly Singapore and Hong Kong), demand for the tri-axle Volvo B9TL remained strong where Euro VI emissions regulations (or their equivalents) had yet to take effect. In preparation for eventual Euro VI adoption, the Volvo B8L chassis was developed as a replacement for the tri-axle Volvo B9TL which only met up to Euro V emissions standards. However, production of Volvo B9TL has yet to officially cease.
The Volvo B8L is currently only produced as a 12-metre bus. The drivetrain comprises a Euro VI-compliant Volvo D8K engine with 280, 320 and 350-horsepower options. Transmission offerings have so far only included ZF, and likely compatible with Voith units.
The B8L is also known to be compatible with the Wright Eclipse Gemini bodywork range produced by Wrightbus. The Hong Kong model is bodied with the second-generation Eclipse Gemini 2 bodywork, while the Singapore model is bodied with the newer, third-generation Gemini 3 bodywork.
This bus has yet to be registered and specifications are to be confirmed.
The first Volvo B8L in Singapore was one of two prototypes produced for initial testing ahead of mass production. The first unit entered trials with Hong Kong bus operator Kowloon Motor Bus in 2017. The Singapore unit has yet to enter service.
The only other B8L produced so far, operating in Hong Kong, is fitted with a Volvo D8K350 paired with a ZF EcoLife 6 AP 1600 BS transmission, which ZF also offers with rear axle steering as an option.
