Optare MetroCity (UK market only) |
The Optare Tempo is a full-size rigid 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 integral rigids. As of July 2017, 233 had been built, including 27 Tempo SRs. The Tempo SR has now been replaced in the UK market by longer variants of the Optare MetroCity, although production of the Tempo SR continues for the Australian market.
The Optare Tempo was launched in October 2004, with the first delivered to Trentbarton in February 2005. It came in four different lengths: 10.6, 11.3, 12.0 and 12.6 metres and it has a raised roofline in the middle continuously to the rear roof spoiler instead of an arched top.
It was originally powered by a Mercedes-Benz OM906LA engine, with a MAN D0836 engine option later introduced, coupled to an Allison or ZF automatic transmission. In 2007, a hybrid version was introduced for London operators. The Optare Tempo has stopped production and got replaced with the Optare Tempo SR.
In October 2011, a restyled version was launched as the Tempo SR. The Tempo SR came in three different lengths: 10.6, 11.3 and 12.0 metres and incorporated a Mercedes-Benz OM906 six-cylinder 210 kW (282 bhp) SCR engine (the MAN engine option being dropped). ZF 6HP500* six-speed transmission could be specified as an alternative to the standard Allison T310R gearbox – both of which feature integral retarders.
Trentbarton were announced as the launch customer for the Tempo SR, taking delivery of thirteen examples between May and July 2012. Following poor sales, the Tempo SR has now been replaced in the UK market by longer variants of the Optare MetroCity. However, Manchester Airport took delivery of a further four Tempo SRs in May 2017 for use on airport car park shuttle bus operations; these buses came from an order intended for an Australian operator, which was cancelled. Trentbarton and Manchester Airport remain the only operators of the Tempo SR in the United Kingdom to date.
