The VDL DB250 (launched as the DAF DB250 in 1991) is a double-decker bus sold in the UK through VDL Bus International's UK dealer Arriva Bus & Coach. A small number of DB250s have also been exported to Istanbul, Turkey.
The original DB250 was originally only available with Optare Spectra bodywork, with the Northern Counties Palatine body becoming available later. The original design was based on the MCW Metrobus for which Optare and DAF Bus International (then VDL) bought the rights after MCW decided to end bus production.
The DB250LF, the low-floor version of the DB250 chassis, is perhaps more well-known as the first low-floor double-decker bus chassis available in the UK. The DB250LF is readily identified by the centrally-exiting exhaust at the rear, which can cause problems with extreme changes of slope. The new version of DB250LF was launched in 2004 which is officially known as DB250+. The design has received a number of modifications, one of which is the use of independent front suspension.
The first DB250LFs were bodied by Optare, with the modified Spectra body which was sold exclusively on the DB250. The first low-floor variant (R222AJP) entered service in 1997 with Alan Peters (trading as A Bus) of Bristol, which narrowly beat a Travel West Midlands DB250LF from being the UK's first low-floor double-decker bus. Later the Alexander ALX400, Plaxton President, East Lancs Myllennium Lowlander and Wright Pulsar Gemini (almost identical to the Eclipse Gemini sold on the Volvo B7TL chassis) also became available. The development of a Wright alternative arose because Arriva wished to buy both the Wright body and VDL chassis. Unable to do so, they took delivery of over 100 Wright-bodied Volvo B7TLs. Wright subsequently developed the Pulsar Gemini in order to win more orders from Arriva.
Despite the DB250LF arriving early to the market, DAF had always struggled to find orders. Travel West Midlands (TWM) ordered 20, for example, but after Dennis and Volvo entered the market with the Trident 2 and B7TL respectively, TWM never purchased more. Despite this DB250s are numberable, by far the biggest number owned by Arriva, mostly for its London subsidiary, but a number of the type can be found with Arriva Midlands and Arriva Yorkshire with both East Lancs bodywork and unusually with the Wright Pulsar Gemini body, these being some of few Pulsar Gemini single-door bodies. Other sizeable operators are Travel West Midlands and Wilts & Dorset.
The DB250LF chassis was also adopted by Wrightbus for the development of its hybrid-powered double-decker bus, Wright Pulsar Gemini HEV.
Production of the DB250 ended in 2006, although examples continued entering service in the UK in 2008. Its successor, the Wright Gemini 2 integral double decker with VDL chassis modules, was announced in December 2007 and launched in November 2008.
VDL DB250(原本叫DAF DB250)係荷蘭VDL Bus(同埋前身DAF Bus)出嘅一款後置引擎雙層巴士,1991年亮相。
DB250嘅部分設計係源自DAF聯同英國Optare喺1989年收購嘅都城嘉慕威曼都城巴士設計。佢嘅前部分同DAF SB220單層巴士類似,而尾軸至引擎部分就同都城嘉慕威曼都城巴士差唔多,不過引擎係由DAF造,而散熱水箱就擺咗喺引擎室右邊。1995年,DAF Bus展出DB250低地台巴士底盤,但佢嘅完整巴士去到1997年至現身。2004年,VDL Bus推出低地台版DB250嘅改良版,是為DB250+。
車身選擇方面,DB250初時只可以配Optare Spectra車身,但Optare同埋DAF Bus脫離United Bus集團之後,就多咗Northern Counties Palatine II車身選擇。至於低地台版就可以配Optare Spectra、亞歷山大ALX400或者Plaxton President車身,後來再加入東蘭開夏Myllennium Lowlander、Wright Pulsar Gemini等車身選擇。
DB250主要係供應英國市場,其中以Arriva集團買得最多,低地台版DB250更係全英國第一款低地台雙層巴士。另外亦有多架DB250賣咗去土耳其,其中非低地台版係配Optare Spectra車身,而低地台版就配MJT車身。
喺2006年,DB250低地台巴士底盤俾Wright用嚟整佢嘅混能雙層巴士,即係Wright Pulsar Gemini HEV。
DB250喺2006年停產,但最後一批新車去到2008年先至投入服務。後來VDL Bus同Wright合作研製新嘅Wright Gemini 2一體化巴士。
