The Optare Prisma was a single-decker bus body that was fitted to the Mercedes-Benz O405 chassis, produced between 1995 and 1998, when it was discontinued in favour of the integral Optare Excel low-floor bus.
The Optare Prisma body was constructed on the O405 chassis with an OM447H 157 kW (211 hp) engine, and was built with Alusuisse aluminium framework, retaining a Mercedes-Benz built front cowl and destination display as standard. The sides and back end of the body, however, followed the styling of other Optare products at that time, such as the Delta and Vecta.[1] The Prisma was also designed with the ability to have equipment for use on a guided busway fitted,[2] with a demonstrator operated by Stagecoach Busways in 1996 being fitted with an AEG electronic guidance system.[3]
Capable of seating up to 54 passengers, to meet Disabled Persons Transport Advisory Committee (DiPTAC) accessibility recommendations, the Prisma has a 320 millimetres (13 in) step at the entrance door, capable of being reduced to 240 millimetres (9.4 in) with a kneeling front air suspension. The passenger compartment could be optioned with three further low steps towards the rear of the bus or a ramped floor towards the rear. Gasket-glazed tinted side windows were fitted as standard.[1][2]
