the introduction of its new Tempo SR model
at Coach & Bus Live 2011, Optare is
aiming to be an even stronger contender
in the 10 to 12 metre heavy-duty single-deck
sector of the UK market.
The first Tempo SRs will be completed before
the end of the year. With Optare’s
new plant at Sherburn in Elmet now coming
on stream, the company is much better positioned
to pursue high volume business with the large
fleets as well as meeting demand from its
extensive customer base in the independent
sector for buses in this category.
The totally restyled Tempo SR replaces the
Tempo model which is renowned for its low
weight, contributing to exceptional fuel
efficiency, its durability, reliability,
passenger appeal and performance.
Optare is offering the new model in three
body lengths of 10.6, 11.3 and 12.0 metres
with standard seating capacities ranging
from 35 to 43. Amongst the wide range of
customised internal layout configurations
are the options of cantilevered seats, sculpted
wheelarch seats and luggage pens.
The 12 metre SR model on show weighs in
at just 9650 kgs (fitted with double glazing
and cantilevered seats), giving it a potential
to carry up to 85 passengers. However, for
high passenger density operations, such as
airport transfer duties, in excess of 100
passengers can be carried.
The appearance of the new SR model is, however,
significantly different. It has a more rounded
front and rear styling in line with that
of other models in the Optare range resulting
in a bus that is more evidently from the
Proven driveline and electronics:
The Tempo SR is offered with the 6.37 litre
Mercedes-Benz OM906L six-cylinder unit as
the standard power unit. This delivers 210kW
(282 bhp) at 2200 rpm and 1120 Nm of torque
at between 1200 and 1600 rpm to ensure smooth
move-offs in all road and load conditions.
The engine meets Euro 5 emissions standards
through the use of SCR technology and AdBlue
as a re-agent.
As with all Optare integral models, the
entire power pack and transmission is housed
in an easily removable cradle using a system
pioneered by Optare and which has become
a hallmark of the company’s products.
This enables fast engine removal for major
repairs and can also facilitate conversion
to other fuel or propulsion systems, such
as low carbon fuels, hybrid systems and even
battery power, to bring an element of future-proofing
to the model.
Operators can specify one of two fully automatic
transmissions, both of which feature integral
retarders. The Allison T310R five-speed is
the standard fitment, with the ZF6HP500 six-speed
as an option.
Tempo SR features the Actia multiplexed
electrical system, which enables faults to
be checked, located and remedied quickly
and easily using a lap-top based diagnostic
programme. The system is designed to allow
the factory fitment of a wide range of optional
equipment and functions, including CCTV systems,
reversing cameras, passenger counting devices,
ticketing machines and tachographs. A full
telematics package can also include a remote
diagnostics capability and vehicle tracking
to support timekeeping and route adherence.
LED lighting is used for all exterior lamps,
excluding the halogen headlamps, making the
Tempo SR more visible in poor light conditions.
Passenger comfort assured:
The Tempo SR is a very accessible bus for
people of all levels of mobility. The wide
two-leaf glider entrance door makes access
easy and a ‘bookleaf’ manual
wheelchair ramp is standard with a powered
ramp as an option. The wheelchair bay includes
a backrest and pivoting gangway armrest.
In its normal position the entrance step
height is 333mm, which reduces to just 245mm
when the front air bags are exhausted.
The tinted deep side windows ensure a bright
and airy feeling inside the saloon which
is enhanced by uplighting throughout to create
a pleasant ambience in all conditions. The
35mm track-mounted handrails are curved,
adding to the stylish interior, and incorporate
palm operated bell pushes with a ‘stopping’ sign.
Exceptionally low interior noise levels
have been achieved by optimising the insulation
package and through the use of a drive axle
engineered for smoother, quieter running.
Drive by noise levels are also low, making
the Tempo SR well suited to operation in
town and city centre environments.
Driver friendly features:
Driver comfort and safety have been key
factors in the design of the Tempo SR with
all instruments and controls ergonomically
laid out to ensure ease of use without distraction
The moulded driver’s compartment is
designed for easy cleaning; the seat is fully
adjustable to allow a comfortable posture
to be quickly adopted as drivers change;
and the telescopic steering column can be
altered for both reach and rake. Two high-powered
windscreen demisters ensure good visibility
and a cab heater helps to provide a comfortable
A notable feature is the Eco Drive dashboard,
which is now a standard feature across the
Optare integral range. This takes information
from the Actia multiplex system and presents
it in a simple visual format, telling the
driver at a glance how their driving is affecting
fuel consumption and passenger comfort and
safety. The system has been clearly shown
to deliver significant fuel efficiency improvements
in operation in other Optare models.
Durable construction for long life:
Tempo SR is built using the proven integral
construction principles for which Optare
is renowned. The basis of the model is an
all-welded, heavy-duty, box section system
combining stainless and high-grade carbon
steel to deliver low weight with strength
Anti-rust protection is applied to all exposed
structural components for long life. A combination
of glass fibre and aluminium modular exterior
panels also contribute to longevity and reduced
weight as well as being designed for low-cost,
fast and easy replacement.
