同意，明明而家d巴士比1999年增加Quota制環保得多
歐三既歐三歐四既歐四，唔係歐三歐四都加晒Filter
反而Quota仲會畀運吉cut，所以quota同環保並冇直接關係 ...
衰D講句, 就算全部巴士都係用加壓氫做燃料,
連CO2都唔洗出, 運吉都照CUT |

以前 Hybrid 車的電池比較大同重，所以唔適合巴士使用。
如今電池體積大幅改善，所以亦適合係巴士上使用。
使用混能巴士的最大障礙其實都係車價問題..... ...
搭單問下, Hybrid 冷狗會唔會俾副冷氣食晒d電而令副 engine 長行义電架? |

都話左混能唔駛交電費咯..........
混能的電力來源除左來自引擎外，另一來源係剎車時的能源再生，
並唔係黎自電廠。
CN9AMT100UP 兄已經解釋唔少。混能車係市區道路的慳油效果
最為顯著，明顯更適合香港環境。
另外，CNG ...
依家有太多唔同類形的Hybrid System，目的雖然相同，但辦法可能會有出入，都係等各位有識之仕補充啦。
Hybrid System 適合香港唔難，但問題係，職業司機會唔會細細力，慢慢o甘踏油門?所以駕駛者的駕駛心態更重要。 |

仲可以有噪音污染，熱污染。
所以，係只要有巴士，運輸署就會繼續cut車。 |

長時間高速/高馬力行車，混燃車甚有可能比普通柴油車用油更多，這是市面上多款混燃私家車運作經驗所得的結果。而天然氣/石油氣方面，其實也只是一個中途方案，車輛仍然會排出各類污染物，長遠而言採用氫為燃料才是解決辦法。如果現在轉用燃氣巴士，若干年後又轉用氫氣巴士，只會造成浪費。 |

雙層方面，反而應向歐盟五型發展，用混能係要交電費的，用天然氣的話加個氣缸上去肯定超高，不過反而最有潛質試驗的係新巴的 33XX，可以試下降低車高去就個 Gas Tank。: l4 D0 n, \; v3 g6 u# E; h
You obviously haven't got a single clue on how hybrid-drive works, so may I suggest you to take a look at this:
http://en.wikipedia.org/wiki/Hybrid_electric_vehicle
...before you carry on with your debate.
And let me just point out, Volvo, Wrightbus and ADL are now offering their hybrid-drive double decker which can deliver, typically, 30% fuel saving whilst, at the same time, providing emission that is 30% lower than the Euro 5 standard.
And for your argument about the supposed supriority of large single decker buses, most of the advantages you quoted have nothing to do with what buses are deployed. Those residental services in northwest NT are successful because of the competitive routing and pricing - I bet you can put a Routemaster or a Dart on them and they will be just as successful.
The fact of the matter is, diesel engine technology has moved on so much over the last decade that they are actually much more environmental friendly than many people realise - You only have to look at the latest diesel cars on sale today for proof. Because of the advance of diesel, gas-powered technology is actually not much cleaner than the lately petrol/diesel engines - and I'm talking about the existing Euro 4 emission standard. The fact that gas-powered vehicle never really out-do petrol and diesel engines, despite 20+ years of trying, speaks for itself really. |

用單層巴士代替雙層巴士行走係不設實際
因為而家有車隊有quota限制，而家已唔夠capacity載人
再轉用單層就真係唔知坐咩 |

hybrid對於市區經常要起步/剎車既環境有好處
反而行高速公路既路段會唔夠電用而轉用返柴油引擎
其實天然氣巴士發展左咁耐, 要試都唔係而家先黎試啦 |

，即系用Fuel cell
