Similar to AD1, These 'production' Dragons are 11-metre long. However, they have different interior configurations and general appearance. For example, individual seats in grey or red colours were used. Also, windows of AD1 are mounted with rubber-gasket, while those on these new Dragons are bonded glazing. For mechanic specifications, the new buses are powered by Cummins LT10 engine with Voith DIWA D863 3-speed automatic transmission, while AD1 is fitted with 4-speed ZF4HP500 gearbox with the same model of engine.

Excluding AD1, there were totally 359 Dragons with 11 metres long (AD2-360) purchased during 1991-97. Configurations among these buses are more or less the same, except that 2+2 high-back seats were installed for the last batch of 80 (AD281-360). These 80 buses were also fitted with modified Nippondenso air-condition system.

AD2 (EU 7058) was withdrawn from service and scrapped as a result of a serious accident in 1996. The bus became the first withdrawn double-deck air-conditioned bus in the fleet. Therefore, there are only 359 AD-class Dragons in service.
