The '''Optare Delta''' was a ] body manufactured by ] between 1990 and 1999 on the ] chassis. The Delta was Optare's first full-size ] body, with the company having previously built ] bodies on ] and ] chassis. The Delta was succeeded by the ] from 1995 onwards, with production of the Delta body ceasing in 1999.
The '''] Delta''' is a single-decker bus body produced for the ] chassis.


==Design==
The dramatic front windscreen was a product of the designer’s experience of driving buses as it maximized driver visibility. It was also an attempt to disguise the bulge of the DAF SB220 chassis stylistically.
First announced in early 1988,<ref>{{cite news |url=https://archive.commercialmotor.com/article/18th-february-1988/16/single-deck-optare-on-the-way |title=Single deck Optare on the way |work=] |publisher=Temple Press |date=18 February 1988 |page=16 |access-date=31 January 2021}}</ref> the Optare Delta was formally launched as the first body for the UK market to be fitted to the DAF SB220 chassis in June 1988.

At a length of {{convert|11.6|m}}, the Delta was marketed to three configurations: as a standard city bus, carrying 53 seated and 24 standing passengers, or to either city or intercity specification with 47 passengers seated hard plastic seats.<ref name="Launch">{{cite news |url=https://archive.commercialmotor.com/article/2nd-june-1988/21/optare-launches-delta-city-bus |title=Optare launches Delta city bus |work=Commercial Motor |publisher=Temple Press |date=2 June 1988 |page=21 |access-date=25 July 2024}}</ref>
The overall design stems from a design exercise into a new trolleybus for the proposed Leeds Trolleybus network in the 1980s. Although the trolleybus network didn’t come to fruition due to political and financial reasons the design was used for the Delta, with very few minor alterations. These included the removal of trolley poles (since the Delta would be powered by a diesel engine these weren’t required) and the replacement of a smooth panel emblazoned with ‘Optare’ with a conventional grill between the headlights.


The Delta was powered by a DAF LC1160 {{convert|11.6|l}} turbocharged six-cylinder engine, and it could be optioned with either ] 4HP500 or 5HP500 automatic gearbox. The Delta's front suspension could "kneel", allowing the {{convert|310|mm}} entrance step to lower to a height of {{convert|200|mm}},<ref name="RoadTest" /> while air springs and a centrally-mounted steering column, unusual for British buses at the time, were also provided.<ref name="Launch" />
The design of the Delta was continued in a less dramatic form onto the ].


Production of the Delta eventually ceased in 1999, around the time the second-generation ] ] began entering production.<ref>{{cite magazine |last= |first= |title=Daughters of Delta |magazine=] |issue=690 |pages=38-39 |date=September 2012 |location=Stamford |publisher=Key Publishing}}</ref><ref>{{cite book|last=Jenkison|first1=Keith|title=The History of Optare|date=2020|publisher=]|location=Stroud|isbn=978-1445696942}}</ref>{{page needed|date=July 2024}}
The Delta sold well during its lifetime but production of the Delta ceased in 1999.


===Articulated designs===
A large number of Optare Deltas are still in use with bus operating companies in the UK, most widely used by ]. They are found in high numbers with ], with the Darlington and Bishop depot having around 18 between them.
The Delta's design was originally utilised by Optare as part of proposals for a ] in ].<ref name="RoadTest" /> Though the trolleybus proposal did not progress further, Optare instead redesigned the bus to be a diesel double-fronted ] on DAF SB220 chassis. A mock-up bus was built, and an order for 12 articulated Deltas was considered in 1992 by ] when the operator proposed a ] serving ] and ],<ref>{{cite news |url=https://archive.commercialmotor.com/article/5th-march-1992/16/northern-alights-on-artic |title=Northern alights on artic |work=Commercial Motor |publisher=Temple Press |date=5 March 1992 |page=16 |access-date=25 July 2024}}</ref> however no orders resulted due to the busway never being approved.


An articulated Optare Delta was eventually developed by vehicle fitters Sutrak UK and BTSE 2000 in 1992, designed for use as a European roadshow vehicle by American ] company ]. Named the 'Amway Showcase', the vehicle was built on a left-hand drive ] articulated chassis and LAG Panoramic coach framework, using a combination of ] coach mouldings, the Optare Delta's front fascia and the LAG Panormaic's rear fascia.

The Optare Delta was a single-deck bus body manufactured by Optare between 1990 and 1999 on the DAF SB220 chassis. The Delta was Optare's first full-size transit bus body, with the company having previously built minibus bodies on Volkwagen LT55 and Mercedes-Benz 811D chassis. The Delta was succeeded by the Optare Excel from 1995 onwards, with production of the Delta body ceasing in 1999.

Design

First announced in early 1988, the Optare Delta was formally launched as the first body for the UK market to be fitted to the DAF SB220 chassis in June 1988. The Delta bodywork featured a distinctive sloping one-piece windscreen with a separately mounted destination display, as well as gasket glazed tinted windows in the passenger cabin, and was constructed with an Alusuisse bolted aluminium frame, which Optare had gained the exclusive rights to use in Great Britain. At a length of 11.6 metres (38 ft), the Delta was marketed to three configurations: as a standard city bus, carrying 53 seated and 24 standing passengers, or to either city or intercity specification with 47 passengers seated hard plastic seats.

The Delta was powered by a DAF LC1160 11.6 litres (2.6 imp gal; 3.1 US gal) turbocharged six-cylinder engine, and it could be optioned with either ZF Ecomat 4HP500 or 5HP500 automatic gearbox. The Delta's front suspension could "kneel", allowing the 310 millimetres (12 in) entrance step to lower to a height of 200 millimetres (7.9 in), while air springs and a centrally-mounted steering column, unusual for British buses at the time, were also provided.

Production of the Delta eventually ceased in 1999, around the time the second-generation low-floor Optare Excel began entering production.

Articulated designs

The Delta's design was originally utilised by Optare as part of proposals for a trolleybus system in Leeds. Though the trolleybus proposal did not progress further, Optare instead redesigned the bus to be a diesel double-fronted articulated bus on DAF SB220 chassis. A mock-up bus was built, and an order for 12 articulated Deltas was considered in 1992 by Go-Ahead Northern when the operator proposed a guided busway serving Newcastle upon Tyne and Sunderland, however no orders resulted due to the busway never being approved.

An articulated Optare Delta was eventually developed by vehicle fitters Sutrak UK and BTSE 2000 in 1992, designed for use as a European roadshow vehicle by American multi-level marketing company Amway. Named the 'Amway Showcase', the vehicle was built on a left-hand drive MAN articulated chassis and LAG Panoramic coach framework, using a combination of Bova Futura coach mouldings, the Optare Delta's front fascia and the LAG Panormaic's rear fascia. Internally, the Amway Showcase featured a broadcasting studio, a portable stage, a NICAM stereo video system, and an IBM AS/400 computer for demonstrating Amway's customer support system. This bus was exported to Ireland for use by Dublin radio station FM104 in May 1996, however the bus was eventually scrapped after the collapse of its suspension frame had rendered it inoperable.

Operators

The combined Trentbarton companies were the largest purchaser of Optare Deltas, purchasing a total of 51 between 1991 and 1993, with all but ten being delivered to Trent Buses, predominantly for use on the operator's Rainbow Routes network.

The second largest operator of Deltas was British Airways, who purchased 49 of the type between 1990 and 1993 for airside passenger transfer services at Heathrow Airport. These Deltas were unique in having three entrance doors, with a centre offside exit door situated opposite a nearside exit door, reducing seating capacity to up to 40 passengers; a batch of six Deltas delivered for use on a ten-minute landside shuttle between Terminal 1 and Terminal 4 had their doors sealed by HM Customs and Excise on each journey to eliminate the need for re-checking passengers and luggage at the destination terminal.

London Regional Transport's London Buses business units took delivery of 35 Deltas between 1990 and 1992, with most being built to dual-door configuration. After initial examples were bought for evaluation by London General and East London in 1989, 19 dual-door Deltas were delivered to East London in April 1992, Prior to this, seven Deltas were also delivered to Westlink in 1990.

Go-Ahead Northern first took delivery of 14 Deltas in 1989, which were followed by an additional five in 1990. Competing operator Northumbria Motor Services took delivery of 17 between 1989 and 1990, while elsewhere in the North East of England, other operators included United Automobile Services, OK Motor Services and Teesside Motor Traction.

Other notable operators of the Optare Delta included PMT of Stoke-on-Trent, taking delivery of nine in 1990, Blackpool Transport, who first purchased eight Deltas in 1990, going on to purchase 20 more between 1991 and 1993, Ipswich Buses, who took its first Delta in 1991, following with another four delivered in 1994, and Fylde Borough Transport, who took three Deltas in 1991. Among the Delta's final customers were Reading Buses, who after first purchasing ten Deltas in 1989, took delivery of its final ten between 1995 and 1996.
