The Optare Tempo is a full-size single-deck bus manufactured by Optare and was launched in late 2004. It is marketed and sold as the replacement for the Optare Excel. It is designed as a lightweight bus, to use less fuel than traditional heavy duty integrals.
The original Optare Tempo came in four different lengths: 10.6, 11.3, 12.0 and 12.6 metres. It can be fitted with Mercedes-Benz engine, with an option of MAN engine followed later on, coupled to an Allison or ZF automatic transmission.
Amongst the first operators in the UK were Trent Barton of Nottingham, Wilfreda Beehive of Adwick-le-Street, Doncaster, and Sargeants Brothers of Kington. Arriva is the only one of the big groups to have taken some on board, for services in West Yorkshire. Regal Busways have bought three vehicles for use on their premier route 1 service between Chelmsford and Canvey Island in Essex. All three buses are fitted with leather seats, power points, and tables. The Welsh Assembly Government purchased several for use on the TrawsCambria bus network, despite protests about the unsuitability of a normal bus for the long distance journeys.
In November 2008, it was announced that Transdev Yellow Buses had ordered 11 Tempos for its fleet, following on from an order of 11 Optare Versas. All were delivered in 2009, with a further 7 delivered in 2010. Soon afterwards another order was announced, of 13 for Arriva Yorkshire, all were delivered in 2009. This is the first order of the type from one of the main UK bus groups.
In February 2010, It was announced that Centrebus Calderdale (Centrebus Holdings) had ordered 4 Optare Tempos for its fleet, to replace the various Dennis Darts on hire. These new Optare Tempos entered service in April 2010.
More Optare Tempos are delivered for the Lim Chu Kang service 971, and service 371.
