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.
History
[edit]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]
Chassis summary
[edit]
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.
