The Bedford Y series was a family of single-decker bus and single-decker coach chassis manufactured by Bedford from 1970 to 1986, when Bedford ceased bus and truck production.
Announced in September 1970, the Bedford YRQ was a 10-metre (33 ft) coach chassis intended to replace the Bedford VAM. The engine was mounted centrally under the floor.
In 1972 an 11-metre (36 ft) version, the YRT, entered production as a replacement for the twin-steer Bedford VAL. [1]
New more powerful engines were introduced in 1975 with the YLQ (10 m) and YMT (11 m).
The 1980 YNT was a development of the YMT with a turbocharged engine, [2] while the YLQ became the YMQ and then the YMP.
The 12-metre YNV Venturer with air suspension was the final development of the Y series, announced in 1984.
Bus and truck production by Bedford ceased in 1986. [3]
The Y series was produced in four different lengths; 8m, 10m, 11m and 12m. The majority were bodied as coaches, though the 8m, 10m and 11m versions were also built as single-decker buses and midibuses. Seating capacities varied, but were typically 45 for a 10m bus or coach and 53 for an 11m. The 12m version was built almost exclusively as a coach, with one exception where a Plaxton Paramount coach body shell was fitted out with bus seats in a high-capacity layout. [4]
Model codes were part of a system introduced by General Motors in 1968. Under this, the first letter (in this case, Y) denoted the basic model range; the second letter denoted the engine type; and the third letter the gross weight range for a complete vehicle. Those applicable to the Y series were as follows: [5]

A further four digits or letters denoted wheelbase, transmission and body type, and the full seven-character code was incorporated in the VIN for each individual vehicle.
The Bedford Y series was sold extensively in the United Kingdom, mainly to independent operators, as well as in export markets. It was fitted with a wide variety of bodies by different manufacturers, chiefly Duple and Plaxton.
The Alexander Dennis Enviro500 is a three-axle double-decker bus built by Alexander Dennis in the United Kingdom. It was unveiled in 2002 and is one of the Enviro-series bus models made by TransBus/Alexander Dennis. The bus was sold on diesel or hybrid-electric powertrains and on Volvo chassis as a bodywork.
Plaxton is an English builder of bus and coach vehicle bodies based in Eastfield, North Yorkshire, England. Founded in 1907 by Frederick William Plaxton, it became a subsidiary of Alexander Dennis in May 2007. In 2019, the maker was acquired by Canadian bus manufacturer New Flyer which then became NFI Group.
The Volvo B7TL is a low-floor double-decker bus chassis which was launched in 1999 and replaced the 2-axle version of the Volvo Olympian. It was built as the British bus operators seemed hesitant to purchase the B7L double decker with a long rear overhang.
The Ford R series was a range of single-decker bus and single-decker coach chassis, built by Ford that evolved from designs made by Thames Trader until the mid-1960s. A number of components were shared with the D-series lorry, including the engine which was mounted vertically at the front of the vehicle, ahead of the front axle so as to provide a passenger entrance opposite the driver. The original R192 and longer R226 models later became the R1014 and R1114 variants which with constant revision and upgrading had become R1015 and R1115 by the mid-1980s. In an attempt to lower the floor height of the vehicle, the turbocharged diesel engine was tilted over to one side around 1978. Synchromesh transmission was fitted as standard but some later examples were equipped with Allison automatic gearboxes to ease the driver's workload in urban areas. It ceased production in 1985.
Duple Coachbuilders was a coach and bus bodybuilder in England from 1919 until 1989.
Bedford Vehicles, usually shortened to just Bedford, was a brand of vehicle manufactured by Vauxhall Motors, then a subsidiary of multinational corporation General Motors. Established in April 1931, Bedford Vehicles was set up to build commercial vehicles. The company was a leading international lorry brand, with substantial export sales of light, medium, and heavy lorries throughout the world.
The Leyland Leopard was a mid-engined single-decker bus and single-decker coach chassis manufactured by Leyland between 1959 and 1982.
Barton Transport was a bus company that operated in Nottinghamshire from 1908 until 1989.
The Plaxton Paramount was a design of coach bodywork built by Plaxton. It first appeared at the 1982 British Motor Show and was built until 1992.
The Plaxton Derwent 3000 was a step entrance single-decker bus body built by Plaxton. It was introduced in 1986, and is not related to the earlier body which was built between 1962 and 1977, with the same name.
The Plaxton Verde was a step-entrance full-size single-decker bus body built by Plaxton between 1991 and 1997. It was built on a rear-engined chassis, the most popular of which was the Dennis Lance which accounted for over half of the Verdes built. The rest were on Volvo B10B, DAF SB220 and Scania N113 chassis.
The Duple Dominant was a design of a coach bodywork built by Duple between 1972 and 1987. It introduced an all-steel structure and replaced the wooden-framed Duple Vega, Viceroy and Vista models.
The MAN Lion's City is a range of low-floor and low-entry public buses built by German truck and bus manufacturer MAN Truck & Bus since 1996 primarily for the European market, but is also available in chassis-only variants worldwide. The name Lion's City has been used since 2006, when MAN's public bus models which had been marketed separately were gathered into one range, when also most models received a facelift. The first models to be introduced were the 12-metre low-floor intercity bus NÜ xx3 (A20) in 1996, the 12-metre city bus NL xx3 (A21) in 1997 and the articulated NG xx3 (A23) in 1998. As with former MAN bus models the power-rating made up part of the model name, giving the NÜ-series buses with power-ratings of 260 and 310 hp model names NÜ 263 and NÜ 313 respectively. The main production sites are in Starachowice and Sady in Poland, but the models have also been built in Germany, Turkey and Malaysia. Initially most of the midibus variants were manufactured by Göppel Bus in Augsburg, later Nobitz.
The Seddon Pennine RU was a rear-engined single-decker bus built by Seddon Diesel Vehicles/Seddon Atkinson between 1969 and 1974.
The Seddon Pennine 7 was a mid-underfloor-engined single-deck bus or coach chassis built by Seddon Atkinson between 1974 and 1982.
The Volvo B11R is a 10.8-litre engined coach chassis available as both two- and tri-axle from Volvo since 2011. It was introduced as the second of the Volvo BXXR series, replacing the rest of the B12B range in 2011, and later its fellow BXXR platform model, the B13R in 2013.
The Wright Contour was a coach body built by Wrightbus from 1982 until 1987. The first entered service with Whittles in 1983. Most were fitted to Bedford Y series, but others were seven Leyland Tigers for Ulsterbus, one Ford R1115 and one ACE Puma IV midicoach.
The Duple Laser was a design of a coach bodywork built by Duple between 1983 and 1986. It replaced the long-running Duple Dominant body as Duple's standard medium-height coach of the mid 1980s.
The Duple 300 Series were a range of bus and coach bodywork built by Duple between 1985 and 1989. The range comprised the 3,000 mm high Duple 300 service bus, the 3,200 mm high Duple 320 coach, and the taller 3,400 mm high Duple 340 coach. The 320 and 340 coaches were announced at the Bus and Coach Show at Earls Court in September 1985 as replacements for the previous Laser and Caribbean. Deliveries of these models commenced in 1986, whilst the 300 bus was launched in 1987 as a replacement for the Dominant Bus. After Duple closed down the designs were sold to Plaxton and a small number of additional 320 bodies were built as the Plaxton 321.
The Duple Viceroy was a type of coach bodywork built by Duple between 1966 and 1972. It was initially launched on lightweight front-engined chassis, but it was latterly built on mid-engined and heavyweight chassis as well. A variant of the Viceroy was the Duple Viceroy Express, which had a bus-type entrance door making it suitable for stage carriage work.
