其實neoplan 係生產一體化車身方面，技術比其他國家較為成熟，但是一體化車身佢嘅失天性缺陷，由其是車身結 ...
全部Metropolitan上層車尾上面都有凸起嗰件嘢，求其搵張Metropolitan嘅相都會見到，絕對唔係乜嘢香港版獨有。而嗰件嘢係用嚟畀引擎室通風（為隔音而用密閉式引擎室），同Metrobus車尾鯊魚鰓嘅功用一樣。
要散熱就當然係靠兩邊尾轆前面各一個水箱去做，部引擎又唔係風冷。Metropolitan過熱係有，不過主要唔係引擎而係波箱，因為個波箱heat exchanger唔夠用而又成日用一波。英國有巴士公司試過改用Voith嘅heat exchanger，問題即刻迎刃而解;P
Metropolitan最主要死因係車身骨架易生鏽，而且引擎cc大、波箱得兩個波、車身重（係全車鋼骨所以重，點會話擺個引擎通風口喺車頂就會重？）導致食油，倫敦嗰164部只係行咗八年就退晒。
Metropolitan推出時Commercial Motor嘅文章，睇吓佢車身骨架有幾咁誇張：

wright 有平治偈, 冇康明斯.
唔一定，雖然StreetDeck似乎得Benz引擎，但Wright有其他車款用康明斯，例如Borismaster：

StreetLite都可以用ISB4.5，不過而家官網冇直接link去呢份brochure，可能而家冇得再揀：

而且賣嚟香港要推埋冷氣嘅話，肯定唔會用標準版嘅四缸Benz引擎，橫掂都係要大改，用ISB6.7都唔奇，不過如果係ISL9就有啲過分。

一體化／integral結構同無大樑底盤完全係兩個概念，以前Metropolitan同Titan B15係integral結構，咪又係有 ...
Metropolitan is not an integral, it has a Scania BR111DH chassis with a MCW body bolted on top of it. It is not even close to a Titan from an integral design point of view.

Indeed Metropolitan is based on BR111DH running units, but as far as I know the chassis supplied by Scania is not a complete one, i.e. only consists of front & rear sub-frames, while the body designed & built by MCW bears the load and holds the sub-frames together. It is not a traditional "body on chassis" bus.
睇個勢,似係歐六兩軸版本
算吧啦呢間公司,有坐過wright底盤嘅人都知垃圾過洗衣機,仲好意思供港
