Perhaps SBST and TIBS are looking at them now to replace the old buses that are reaching 15 years old.

Mercedes-Benz

Volvo
Idea All Volvo CNG buses are listed as "Euro 3" emission standard in their specifications but the 2 Volvo B10BLE-CNG demonstrators are already Euro-4 and granted ARF exemptions by LTA for having met stringent emission standards.
Idea Volvo Super Olympian is listed as "Euro 3" emission standard in their specifications. So are they Euro 3 or Euro 4, since they are bought so recently? And it's quite unbelievable a bus with an engine that sounds like a "vacumn cleaner" is so clean. If it's Euro 4 it'll be quite impressive.

DesignLine Electric Hybrid City "Shuttle" Bus

Idea it should be noted that current diesel buses can be retrofitted with a CNG engine.

Idea it is noted in some reports that CNG buses consume more fuel due to it being 700kg heavier (estimation) than its Euro III diesel counterparts, and that CNG engines are 10%-15% less efficient than diesel engines though they are cleaner. that could explain why SBST mentioned that the 2 Volvo CNG buses costs 30% more to operate.

How long does it take to go from 0 to 100km/h?
How long does it take to go from 0 to 100 mph?
How much Torque?
How much Horsepower?
Top Speed?
Turbo Type?

^tamago^ SG

for buses, it's uncommon that acceleration up to 100km/h is taken into account. in fact, all but a rare few single-decks are fitted with 60km/h speed limiters as required by the LTA. the more important thing is the ability to handle frequent start-stop operations and have optimum acceleration.

from the speedometers of most buses in Singapore, the top speed should hover around 140km/h to 160km/h.

and the Volvo website is not so technical so i can't fish out much.

Volvo 7700 (using D7C engine)
Horsepower: available in 215, 250 & 275hp flavours
Torque: Not known
Top speed: Not applicable in singaporean context
Turbo type: Not known

Volvo B12LE (using DH12 engine)
Horsepower: 340hp only
Torque: 1200 or 1700Nm
Top speed: Not applicable in singaporean context
