CNG Taxis... Comfort, CityCab, SMRT had a few units before, but in March this year, all withdrawn. Toyota dissapointed with performance.Originally posted by SBS1985C:Got such thing as CNG taxi meh ? Never see B4 .... Which company operate them?
Mercedes, on the other hand, brought one trial unit in. SMART taxis got it. Earlier this month, 30 more units were introduced, and a further 40.

my choice is Diesel. Cheaper in terms of fares, and cheaper for the cabbies to operate. Diesel is also widely available, and reliable.

CNG - Compress natural gas .... less powerful , cleaner omissions , quiet engine . Hard to get the CNG , only Jurong Island available currently . More expensive , full tank travelled less mileage , Full-Tank = 250 km only .
Euro V Standard Diesel ......extremely powerful , equally clean omission , less noisy engine , cheaper , slightly more expensive than Euro 2 Diesel ( now no more ) , available everywhere , can go up to 600km per full tank .
Enviromental wise =CNG ......economically = Euro V Diesel .
Less hassel for cabbies taxis using Diesel . -
But CNG takes a long time to refuel, and has very short legs... anyway, I personally do not feel save seating beside a Compressed gas Bomb.. Accident what happen ? Die also die without a whole body.. I think.
While, Diesel gives good torque, longer legs and filled as usual, and do not burnt easily. Diesel nowadays also give out less polutants than petrol.
So, I will vote Diesel. -
As for me
I'd prefer Diesel Taxis as it is cheaper than the CNG taxis. And also , Diesel runs faster than the CNG ones. -

why they don't use LPG in singapore, as LPG taxi is available widly in Japan and Hong Kong, and talking about time bomb, so far, i've never heard the LPG taxi goes into flame beside, even in the biscut body of Toyota Crown Comfort (the LPG tank won't get damage in a big accident).
CNG taxi is just rare, even in Japan.Originally posted by MobyDog:But CNG takes a long time to refuel, and has very short legs... anyway, I personally do not feel save seating beside a Compressed gas Bomb.. Accident what happen ? Die also die without a whole body.. I think.

Sorry all for coming into this forum so late, as I am a new registered member.
Talking about gas, oil, diesel - I can be considered as technical qualified personal.
I had experience managing fleet of 60 trucks before.
My previous companies had also tested battery powered vehicles,
I had seen CNG vehicles - (local/oversea)
Taken LPG powered vehicles (oversea - China)
I had also seen Duel fuel powered vehicles (mixed, electric + (some thing else)
Few fair practical and commercial points that I would like to highlight for Taxi only , there are as follows:-
Time Bomb
Talking about "Time - Bomb" with reference to any motor-engine vehicles, all can be considered "Time bomb" if no handled and/or driven properly. (except solar powered or battery driven vehicles - not practicable)
Competitive Fare
As the taxi drivers will be competing with other public transports such as Bus and MRT. The fare must be kept low but profitable in order to be competive.
Public Image
Unfortunately, we don't see much publicities done to promote "Taxi" as a alternative and cheaper source for replacing other type of public transport. Hence Taxi can be only classified as a "premium public transport" to consumer.
[url]Market Competitiveness for Taxi as Public Transport[/url]
To improve their competitiveness, I would look into various areas.
a) Cheap vehicle price (Waivered from requiring COE)
b) Import / Land Tax (Waivered for public transport)
c) Road Tax (Waivered for public transport)
d) Alternative fuel
As the first 3 will required the Ministries to look into it. I would only touch on d) alternative fuel.
D) Altenative fuel
I would not go further for those items that got no valve to evaluated or explore further:
1) Petrol - Out - Too expensive
2) Diesel - Will be out - Getting too expensive
3) LNG - No practical now as Singapore still no prepared for
4) CNG - Can be considered only but may not be practical
5) LPG - Should be considered.
6) Others, battery, solar - Out (no pratical sense)
Singapore is a very small island country, however, we are fortunate to have a well built traffic infrastructure that is very well planned. Hence, with little sacrification of convenience, we may be able to provide them a cheaper way of operating this public transport.
2) Diesel is related as a product from oil. Hence any increase in oil price will direct increase in diesel. It will likely to see raise as price is likely to be up/up all the way.
3) LNG will be practical when there is the infrastructure builted.
4) CNG may not be practical in the term of energy in gaseous form is less then it is in liquid form comparing the same volume cylinder. To compress gas, there will be a limit that you can go for.
(For your information, modules can be reduce to 600 times in liquidified form at very low temperature.
5) LPG As mentioned, it is liquidified, hence the energy is more than gaseous form. LPG coming from petrol as a by products, can be easily obtained. Look like the one you used in your house hold, bottled gas.
Compared LPG to LNG, due to the component inside both. LPG mainly pethane while LNG mainly methane. (Any chemist to help me on LPG? please confirm, I don't wish to misled anyone).
LPG will have higher energy compared to LNG (under same pressure supplier, cylinder volume, supply conditions. There is no need for high storage of LPG around any petrol service station as this only mean to serve taxi only. The various distributer can arrange and collect the bottles for refill at their terminal.
I would have taken LPG powered taxi, you can have air-con etc. Most importantly, the fare may be able to be capped at a lower price.
For your reading and thinking only.

Diesel is not going to be cheap future, in 2000, I purchased at around $0.40 per litre now is about $1.00 due to the oil hike.Originally posted by sinicker:ah? deseal already return ah. return if cap is not sealed properly.
Go for LPG, less maintenance and pollution. I had taken in China, very quite.
Run out still can use home bottle to "tong" for a while. (Just kidding) Go for LPG so that in a case of LNG available, convertion will be also easiler.
Note: Check on duties needed for LPG and LNG or not. I know for sure petrol and diesel got to paid duties. -
i prefer diesel as some diesel engines have built-in turbocharger..improving hp..but petrol owns
