The Volvo B10M was a mid-engined city bus and coach chassis manufactured by the Swedish automaker Volvo between 1978 and 2003. It succeeded the B58 and was equipped with the same 9.6-litre horizontally mounted Volvo diesel engine mounted under the floor behind the front axle. An articulated version under the model name Volvo B10MA was also offered, as was a semi-integral version known as the C10M, with the engine in the middle of the chassis.
The B10M was one of the best-selling chassis in the United Kingdom throughout the 1980s and 1990s. Having originally been produced only as a coach chassis, the B10M was made available as a city bus, in which form it was also very popular.
It was available as B10M-46, B10M-50, B10M-55, B10M-60, B10M-62, B10M-65 and B10M-70, where the number represents the wheelbase in decimetres. Many bodybuilders did however shorten or extend the chassis to fit their needs. No later than 1981 a tri-axle chassis was introduced, available as B10M-50B, B10M-55B, B10M-60B, B10M-65B and B10M-70B, with some bodybuilders extending them up to 7.25 metres wheelbase.
A double-decker version of the B10M was developed for Strathclyde PTE in 1981. It was launched in early 1982, with a downrated engine from the coach, and was named Citybus (also known unofficially as B10MD or D10M). Most early examples were bodied by Alexander Coachbuilders, who provided a modified version - common to all Volvo double-deck chassis bodied by the company after 1980 - of their popular and attractive R type bodywork. Eastern Scottish and Fife Scottish bought many of these early versions in 1985-1987. Two were exported in 1984, one of them to Singapore Bus Service and the other to Kowloon Motor Bus, but was destroyed by fire in 1988. The Citybus lasted until the end of B10M production but fell out of favour after Volvo re-engineered the Leyland Olympian as the Volvo Olympian in 1993.
The B9M was launched in 1982 as a light-weight, stripped-down, budget version of the standard B10M. It was available as B9M-46, B9M-50, B9M-55 and B9M-60. Although technically not a successor to the B57, it found more or less the same place in the markets where it was available. The B9M had the same 9.6-litre engine as the B10M, but at lower outputs. It sold well in the Nordic countries, with the exception of Denmark, where only a few were sold. The model was available at least past 1996.
B10MT and B10T
C10M and B10M-C
In 1984, Swiss bodybuilder Ramseier & Jenzer collaborated with Volvo to unveil a semi-integral coach known as the C10M, with the engine in the middle of the chassis. Production of the C10M was ended in 1987, but the position of the engine was still available as an option and became known as B10M-C.
In the 1990s, Stagecoach standardised on the bus version of the B10M as their full-size single decker. Most received Alexander PS bodies but some received Northern Counties Paladin bodywork. Stagecoach also took numerous examples of the coach version with Plaxton's Interurban bodywork and Jonckheere's Modulo bodywork. South Yorkshire Transport and Kelvin Central Buses also purchased large numbers of the type with Alexander PS bodies.
The B10MA articulated variant was of limited popularity among bus operators in the UK. British Caledonian Airways took four in 1988, the next examples sold in Britain were supplied eight years later, with the delivery of four to Ulsterbus. Stagecoach was the biggest customer for the model in the UK, purchasing 18 in the mid- to late-1990s, with the last delivered in 1999.
The first 200 Volvo B10M Mark 2s were delivered between March 1988 and April 1989. They were bodied by Duple Metsec and Walter Alexander. Some of them were converted to air-con buses in 1999. 1 bus was sold to New Zealand and 1 bus became "Heritage on the Move" bus in 2002, later was scrapped in January 2006. The remaining 197 buses were all de-registered between 1 March 2007 and 13 May 2008 after all completing 19 years lifespan. Upon de-registration, all of the buses were replaced by Volvo B10M Mark 3s and 4s. These were originally from Bedok North, Ang Mo Kio, Bukit Batok and Hougang bus depots. Several Striders were transferred to Soon Lee Bus Park to replace the outgoing Leyland Olympian 2-Axle.
The second batch of 300 Volvo B10M Mark 3s were delivered between November 1992 and June 1993. All units were bodied by Duple Metsec and had received mid life refurbishment. They were all retired between November 2009 and June 2012, as most units received a 2 year lifespan extension due to insufficient replacements. These B10M Mark IIIs were being replaced by B10M Mark IV DM3500 buses for services 160 and 170, and has been planned since 2001.
The third batch of 475 Volvo B10M Mark 4s were delivered between June 1995 and December 2000. They were bodied by Duple Metsec and Walter Alexander Strider. As most buses have undergone mid life refurbishment, most buses had their lifespan extended by 2 years due to insufficient replacements. Buses registered from 1997 did not receive a lifespan extension owing to large numbers of replacements being registered. In 2017, 30 units of the last 50 DM3500 bodied buses received a 1 year extension due to insufficient replacement buses. These buses will retire in December 2018.
For Expo '85 in Tsukuba, Fuji Heavy Industries bodied 100 B10MLs. Seventy-nine were exported to Australia in 1986 with Brisbane Transport, Busways, Grenda's Bus Service, Hornibrook Bus Lines, Invicta Bus Service, Kangaroo Bus Lines, Metro-link Bus Lines, Metropolitan Transit Authority, Premier Roadliners, Sunbury Bus Service and Surfside Buslines purchasing examples.
From 1983 to 1986, a number of B10Ms was built and used in the United States. The American B10M was manufactured mostly in its articulated form (which was purchased by SEPTA, SamTrans, and New Jersey Transit) though a standard length B10M model was made for the RIPTA with one example going to SEPTA as compensation for delays. Canadian production of the B10MA articulated bus under licence to Ontario Bus Industries nearly took place, however it fell through when that company negotiated a more favorable deal with Ikarus Bus.
In Australia, the B10M was purchased by government operators Adelaide Metro, Brisbane Transport and Metro Tasmania, as well as private operators, with large fleets built up in Sydney by Busways and Westbus, and in Melbourne by Grenda Corporation and Sita Buslines.
The articulated version of the B10M constructed by Saracakis under the name "Alexandros" in 1993, 1995 and 1997. All the buses were ordered by Thessaloniki Urban Transport Organization (ΟΑΣΘ) in Thessaloniki, Greece.
- 1993 version was featured with steering in the rear axle.
- The 1995 and 1997 are facelift versions and the chassis on the rear part was changed.
In Thessaloniki 44 buses (1997 version) still in use but OASTH fitted them with modern telematics GPS tracking systems. The older versions were recycled and some of buses were sold to Astiko Ktel Patron (the transport organization of Patras), and are still (Q3 2015) in use in the city of Patras, Greece. They operate routes connecting the outskirts of Patras to the city center and the city center to the University of Patras in Rion. In 2015, all the Astiko Ktel Patron buses were fitted with GPS tracking systems for use with modern real time bus arrival boards at the bus stops and a mobile application.
The B10M as a single-deck bus was complemented (and was largely replaced) by the low-floor rear-engined B10L and B10BLE chassis in some markets in the late 1990s. In 2001 the B10M was replaced by the B12M, sporting a larger 12.1-litre engine and the engine position of the C10M/B10M-C.
