In terms of POWER!!!!!!!! What is the most powerful bus?

Recommended Posts

Which bus has the most HP and powerful yet efficient engine?

 

 

Going out on a limb, but I think the MCI J4500 powered with a Cummins ISX engine. The ISX can be rated at either 425 or 450 HP. ISX replaced the ISM (M11 basically) in 2010. The DD13 (another engine option for the J4500) also ties the ISX as well in terms of HP.

The New Flyer XD40...very efficient, and those things can take off!

 

 

They can't take hills for shit, they are not the most powerful.

Even without the LBSS...they couldn't take Grymes Hill for shit. The Orion Vs took Grymes Hill better than all 3 of the new buses.

 

Don't try and justify what I've known since they arrived at Castleton.

It's the opposite buddy.

 

As for the most powerful, the 2011/12 C40s. Just going by from experience in person.

When it comes to power, its the motorcoaches hands down. The MCIs, Vanhools, Prevosts and ect, they of course have more power than the 40ft buses running around.

With that said, the Orion V's are a bit sluggish, though it may be due to its powerplant.

 

In my experience, in general, buses equipped with Cummins engines have a fast accelaration, yet tend to have a difficult time running at a constant speed. With Detroit engines, it is almost the exact opposite.

 

While I can't say all that much regarding transmissions, Allison knows how to make the ride smooth. Personality is just an extra.

Cummins have more output power in general. There are some DD powered buses that can match the power of a Cummins powered bus.

Any specific reason why, other than the way they are each built?

This topic is kind of pointless. The old Detroit Diesels were the most powerful. Seeing as 99% of all new diesel buses have the same Cummins ISL engines with 280hp, and 99.9% of the CNG's have the Cummins ISL-G most are about the same. However, it depends on the wieght of the vehicle, and the calibration of the transmission.

In terms of today's MC offerings, both DD and Cummins offer an engine that can be rated at 450 hp and 1650 lbft torque. Fuel efficiency is another matter.

mmmmmmmmmm this should not be what is the most powerfull bus but what is the most powerfull engine/powertrain in a bus. Remember it all comes down to what the TA orders for its specs.
