Optare Solo

Encyclopedia : O : OP : OPT : Optare Solo

The Optare Solo is a low floor midibus manufactured in Leeds, UK by Optare since 1997. The name "Solo" is a play on the low-floor status of the bus, the manufacturer believing its vehicle having an entrance "so low" to the floor, namely 200 mm with kneeling suspension. The innovative design, featuring a front axle ahead of the entrance, gained the bus a "Millennium Product" award, along with "The Queen's Awards for Enterprise 2000".

Construction

It is an integral bus (as opposed to a separate chassis and body) built in a modular design, with steel frame and GRP panels. The Solo is powered by a Mercedes-Benz OM904LA engine, which produces 122 bhp or 147 bhp (91 kW or 110 kW) according to specification, and its typically mated to an Allison 2000 fully-automatic gearbox. Later, an option of Cummins ISBe engine was available, a 6-cylinder unit producing 185 bhp (138 kW). There is also the option of a 4-speed Allison AT545 gearbox, but this is not so common. In 2005 a hybrid Solo was constructed, using a small diesel unit and an Eneco battery propulsion unit.

The Optare Solo is available in various lengths, 7.8 m, 8.5 m, 9.2 m, and 9.9 m, all at 2.5 m width. The chassis type code of the Solo carried the length - M780 corresponds to 7.8 m, M850 to 8.5 m, and so forth. Cummins-powered Solos required extra rear bodywork to accommodate the larger engine, which increased the length of the bus by 0.3 m. However, this is not reflected in the chassis code, so an M990 Solo, Cummins powered, is in fact 10.2 m in length.

Along with the launch of the 9.9m model, the Solo was also first offered with LED-type rear lights, as opposed to the standard rectangular clusters.

Seating capacities ranged from 25 for an M780, 29 for an M850, 33 for M920 and 37 for an M990.

Slimline

-->

A narrow-bodied version named the "Slimline" was launched in 2004 with the first examples entering service in August. It is 2.33 m wide, and identifiable by small wheelarch extensions mounted to the rear. Available across all lengths except the M990, the Slimline is identified by having an SL-suffix in the chassis code, e.g. M780SL for a 7.8 m long version. The compact size of an M780SL, with its 25 seating capacity, has seen it being a popular choice for replacing ageing vehicles from the minibus era, such as MCW Metrorider/Optare MetroRider, and other van-based buses.

SE

In June 2006, Optare announced the arrival of another Solo model - the Solo SE. At just 7.1 m in length, it is the shortest Solo offered, and is capable of seating 23. It also utilises a single-piece entrance door. The is a variant of the Slimline - hence it is 2.33 m in width, but noticeably the rear track has been reduced compared to previous Slimline models, eliminating the need for wheelarch extensions on the rear of the bus. Optare also plan to produce the SE in the 7.8 m length.

Solo Abroad

The Optare Solo is sold mostly in the United Kingdom, but has been exported to countries in Europe, such as Denmark, where the buses are fitted with dual entrance/exit doors. Exported models are typically M920 variants.

In the United States, the Solo is sold under the NABI company name, and is called the 30-LFN.
