After restructuring of MAN's bus division in 2009, Neoplan is concentrating exclusively on luxury coaches and due to that, Centroliner was discontinued without Neoplan-branded successor.

[1] [2][5] The Neoplan Centroliner was the third type of German double-decker introduced in Hong Kong (the first being the Mercedes-Benz O305, and the second the MAN 24.350 HOCLNR-NL).

A total of 20 Centroliner N4026/3s (fleet number AP1-AP20), equipped with Cummins M11-305E21 10.8 litres (659.1 cu in) straight six diesel engine and ZF Ecomat 5HP590 five-speed automatic transmission, entered service in August 1999.

In April 2001, KMB acquired two Centroliner N4426/3s (AP131-AP132) which were fitted with MAN D2866 LOH-27 straight six common rail Euro 3 turbodiesel engines, and either a four-speed Voith DIWA864.3E or five-speed ZF Ecomat 5HP602C transmissions.

They were coated with special metallic 'flip' paint, which shows different colours (mainly green and purple), depending on the angle of light reflection.

They were the test buses of Eco-driveline (with large differential gear ratio, engine with high low-end torque and six-speed automatic gearbox).

The bus was painted in gold with dark brown skirt, which is the standard livery for other straight-staircase low-floor buses such as TransBus Enviro500 and Wright-bodied Volvo Super Olympian.

Some believe that it is caused by the difficulty in maintenance by NWFB, or due to the fleet quota limit set by the Transport Department of Hong Kong.

A Kowloon Motor Bus Centroliner (fleet number AP69) was forced off a viaduct by a lorry on Tuen Mun Road on 10 July 2003 and was subsequently written off.

The lorry driver involved was sentenced to 18 months in prison after being found guilty of causing death by dangerous driving.
