color=Silver]為何新巴有新車都冇680份，680都要用舊車，近年先有些較新的有頭屏的那種﹖

大把新巴路線都只係用3A黨 la,就好似970 系,101 依類線王,點解新車就一定要有680 分先?
舊

咁依家新巴都已經將所有最新有頭枕的車
已經會優先比680同682用... (仲有82)
都唔差啦?

至於將來新直有無680份，有排都唔會知...

老友，你唔覺新巴的最新車都是俾682先，新里程60xx、509x-51xx及12xx都是給682的。而3A俾970是因為南區多數要用細車。

以本人觀察，你有幾點錯處
1. 已有多年，60XX未被編配行走東隧線，包括680、682
2. 60XX多數行走2X、8P、720、720A
3. 若要用細車，970、970X為何不能被編配多些14XX、16XX、33XX呢？你的講法不成立
4. 680不時也會被編派較新的車種，包括你所說的509x-51xx及12xx

若要論舊車，南區眾線用車不是比680舊得多嗎？
難道南區又要嚷著一定要用最新的車種嗎？

1. 佢又冇講錯, 你都冇講錯..60XX初時真係有行682, 之後點解唔行得東隧? 問下隧道公司部拖車先啦!
4. 680而家同682都開始一時時啦..不過新巴對呢兩條佢旗下最長的線路一向都幾睇重的...

香港禁止柴油車輛?
你講柴油私家車呀
好明顯係稅率唔同o既問題
除非可以分開私家車用柴油同商業車用柴油啦

其實呢個答案唔算100%正確
真正柴油私家車出唔到牌0既原因
反而係私家車0既廢氣排放要求同商用車唔同
呢個0係早幾期0既汽車雜誌度有專欄提及過

不過講真0個句, 柴油車比汽油車適合香港
因為柴油車燃燒比率一般都高過汽油車, 扭力亦較大
適合越野或經常上落斜路時使用
另一方面, 柴油價格一直都比汽油廉宜超過一半
燃料費相對慳番一大筆


PS 我記得早前計算過舊年年尾其中兩個月份0既石油氣費
發現小巴 每日入三次氣(由0至滿)
燃料費比 每日入兩次柴油(由0至滿) 高
(石油氣消耗量本身已經大過柴油, 連入氣次數都多過柴油
長遠計石油氣唔係賺多柴油幾多)

If anything, I see hybrid-powered buses to be the more likely candidate to appear in HK in
short term, esp. London is looking to evaluate a few hybrid double deckers like the Wright
HEV and Volvo's hybrid "B9TL"s this year. If the trial proves successful, I think we stand a
good chance to se the first hybrid double decker in HK in the next 2/3 years.

Personally, I agree with this point of view.

As hybrid buses can reduce the consumption of fuel
and emission of wastes(CO2, Particulates, NOx)
What it have to do before introduced to Hong Kong
is just make some adjustments to suit the unique situation in Hong Kong

I am looking forward to see the first hybrid double decker introduces in next few years
(As bus companies and  the Government need time to evaluate it)

...which will be the biggest challenge of the lot.

The problem of hybrid buses is they require very good cooling system for the powerplant,
but in HK, the hot weather is not going to help at all. When London introduced 6 Wright
Electrocities, which is just a Dart-size vehicle, in 2005, they suffered a lot of overheating
problems, esp over the summer.

Another thing that is not helping is the HK-spec double decker will require more power
to power the air-cond, which eats up a lot of power, and the bus itself, which will be a
lot heavier as a result. To do that, manufacturers will have to rely on better battery/
hybrid technology, as they always are, in the future, and try to find space to squeeze as
many battery units as they can. Of course, they can also go for a bigger dieseal engine
as a backup, but in doing so, the whole point of hybrid power is going to be diminished
badly.

Having said that, I still see a hybrid double decker to come to HK in around 5 years time.
