Volvo B9LA have the same engine as B9TL as there are D9B310 and D9B360
-
The Citaro G would still be more driveable than the B9LA because it has a large displacement 12L engine which produces higher torque at low engine speeds, whereas the B9LA has a lower displacement 9.4L engine. Both the Citaro G and B9LA are available in CNG versions, the former with a 326hp 12L engine and the latter with a 300hp 9.4L engine.

DaveYou can't tell by looking at 12L engine or 9.4L engine
but i think that MAN lion' city G and Volvo B12BLEA will be better :D:D

It's common sense. A higher capacity engine is able to reach its peak torque at lower revolutions than a smaller capacity one.And how do you "see" torque?

Volvo B9LA is D9B360 with 360BHP. Torque: 2000NM
Mercedes-Benz Citaro G is 354BHP
Volvo B12BLEA with D12E460 with 460BHP. Torque: 2500NM
MAN Lion's City G 360BHP

If you don't know, don't post.
The Mercedes-Benz Citaro G or O 500 UA has a 12.0L engine that outputs 260kW (354hp) @ 2000rpm and 1600Nm @ 1100rpm.
The Volvo B9LA has a 9.4L engine that outputs 265kW (360hp) @ 1900rpm and 1600Nm @ 1200-1400rpm.
The Volvo B12BLEA has a 12.1L engine that outputs 250kW (340hp) @ 1400-1800rpm and 1700Nm @ 950-1400rpm.
The MAN Lions City G (A23) or NG-chassis (A24) has a 10.5L engine that outputs 228kW (310hp) @ 1700rpm and 1550Nm @ 1000-1400rpm or optionally 257kW (350hp) @ 1700rpm and 1750Nm @ 1000-1400rpm.
It would not be wise to purchase Volvo B12BLEAs as these suffer from high fuel consumption, as experienced by State Transit/Sydney Buses. The best overall performer (considering economy vs. power) is the Mercedes-Benz.

if you say me not know that mean you say them not knowing the spec la
Dont mess with the expert. You are rude enough to even suspect that what he says is not accurate.

DaveNot forgetting to mention of the brake problems that they are suffering right now. Which has led to drivers boycotting the B12BLEAs.

I've told you umpteen times that the D12E460 engine option is available only to coaches modules and optionally, B12MA.
No automatic gearboxes offered by Voith or ZF can handle such a powerful engine. The ZF6HP604 can handle a maximum of around 1700Nm, which is around the peak torque of the D12E340 engine.

Very much agreed. He is the subject matter expert in this area. :) -

Yeah, although I am not willing to speculate on the exact problems at this stage. With the price of fuel being so high these days, an operator would have to be insane to want to buy B12BLEAs.

The D12E engine is not an option on B12BLE and B12BLEA city buses. This is because it is a vertical engine for trucks and coaches only. The design of the B12BLE and B12BLEA requires an engine that is able to fit under the floor of the bus at the rear. Therefore the engine used on the B12BLE and B12BLEA is the DH12E.
You are right regarding the transmission issue as well. The only real solution for an engine that outputs 2000Nm is the new ZF-Ecolife 6-speed automatic transmission.

DaveOops. Haha. I forgot to put the "H" in.
Hmm anw, i thought the B12B and B12M also uses the DH12E? Correct me if im wrong tho.
I see. The only auto transmission that i can think of that can handle such high load of that of DH12E460 is an Allison gearbox. That option alone wouldn't have been feasible either.

BC were doing trial and familiaing themselves on this bus at KJDEP just now. Keep on and off headlight/signal light. Playing with EDS as well. EDS Switch between Sv 190, Sv 700 and off service, plus "Ezlink out of order, please pay cash" etc etc.
Bus was spotted turning out from KJDEP just now. Might be heading to CCK now. Maybe someone can go CCK now to double confirm. or it might doing trial around kranji and sungei kadut area.

SMB1H spotted at Choa Chu Kang Interchange on afternoon 26/6/08. Also spotted on 27/6 travelling within Choa Chu Kang.

Yes, the B12B and B12M have DH12E engines.
Apart from the ZF-Ecolife, Volvo's own i-Shift transmissions can transmit 2000Nm of torque and are also capable of automatically changing gears - another possible option if required.
