But do remember that the a/c taps power from the engine as well. A NAC bus would mean that the engine has no additional aircon compressor to drive.Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.
Less weight= more power
sleeker design = more speed
flat design = less speed
The B9TL will have a higher top speed in Singapore then the others as it has a sleeker design. Think of aerodynamics of a car and then you'll know. For the 3rd theory, gearbox and power not only determines top speed but the design also plays a part. Take Bus A and Bus B to have the same engine, gearbox but different design. Bus A is flat while B is sleeky. Take to a drag strip and test them. You'll see that Bus B comes in first. The Nissans tend to have a low top speed because of the front bumper.
I think 60km/h hardly allows for significant air resistence.Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.

I think Don't talk physics here. Not in science class lar boku-chan....Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.

Yeah, I agree. If we are talking like maybe more than 150km/h, then air resistance will be more significant.Originally posted by SBS3625D:I think 60km/h hardly allows for significant air resistence.
One point i would like to make is that, in order for the UD to be slow all because of the bumper , the bumper would have to weigh almost a ton. That alone is impossible ,as the bumper is either a plastic or a hollow metal tube.Originally posted by Class 55 Deltic Fan:The Nissans tend to have a low top speed because of the front bumper.
hehe...i luved TIB581Y. quite special. lock at 1st and 2nd gear for quite longOriginally posted by patdog112:SMRT merz 0405...
i luv the engine sound.. but some are weak already
I rmbr taking a B10M MKIV on 161 which chionged on the third lane until the turbo whistle was damm loud.Originally posted by carbikebus:Vovlo B10M MKIV DM & MKIII DM & OAC Scanias(Exclude JBs ones) are rated slow.
Only a few can run.....Originally posted by Scania N113CRB luver:I rmbr taking a B10M MKIV on 161 which chionged on the third lane until the turbo whistle was damm loud.![]()
SBS1987Y- can speed up to 70km/hOriginally posted by carbikebus:Only a few can run.....
