The Ford R-Series is a range of bus and coach chassis evolved from designs made by Ford's Thames commercial vehicle subsidiary 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 (nominally 10 and 11 metres long respectively with 140bhp engines) 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.
The R-Series was principally a competitor to the various Bedford chassis that were also successful during the same era, both makes being cheaper alternatives to offerings from the then market leader Leyland and later foreign imports such as Volvo and DAF. 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.
In the United Kingdom the design was popular during the 1970s, when considerable financial assistance was available to operators for fleet renewal, but following the election of the Conservative Government in 1979, the subsidy money began to dry up causing demand for full-size buses and coaches to decline and the last R-Series was built around 1986. Front-engined buses have generally fallen out of favour in Europe, as new accessibility requirements favour rear- or side-engined designs so as a low front entrance can be provided. Few examples of the Ford R-series remain in current passenger use, but many have gone on to second lives as mobile homes and stock car transporters.
Another significant user of the type was Jersey Motor Transport, who during the 1970s and 1980s purchased little else. The operational fleet consisted 100% of this bus model for several years during this period, and was chosen because of the manufacturer's willingness to supply chassis of non-standard width and length to suit local size limits. Many of these vehicles received bodywork by Duple whose narrow width Dominant also found buyers on other chassis in the UK, but earlier examples were constructed by Willowbrook and later versions by Wadham Stringer. JMT also had a number of longer, wider examples which had started life in the late 1960s with Trimdon Motor Services in the north-east of England; these Plaxton-bodied buses required special dispensation to operate on the island being restricted to certain services where the roads could accommodate them and were all sold for further use after a few years.
