Mississauga Transit 2007 D40LFR

A ride on board one of MT's newest buses, a 2007 D40LFR (#0727) which was delivered a few weeks ago and was just put into service 4 days ago as of this post. This is the first of the 3 parts, it's on the 3 from the City Center Terminal to Kariya Drive and Burnhamthorpe.
Powertrain:
Cummins ISL ULSD with the Voith D864.3, 4 speed transmission.
Axles:
MAN

She sounds lovely with that Cummins ISL and Voith combo

[@brownbrownson]

wow, that bus even sounds clean... so do our DE41LFRs... DD S50s sound light, and Cummins engines make the bus seem like a heavyweight wrestler... cool stuff..

The 06XXs have the same axles and powertrain yet they still sound different. The axles sound the same, the engine sounds lower pitched though.

All I know is that it doesn't sound like the ISLs we already have!

[@MT0603]

Now, the 07XXs run on ULSD while the previous models run on normal diesel.

[@MT0603]

They petty much sound the same, except the older ISLs are a little higher pitched.

Can you elaborate? :)
I'm not working in Mississauga anymore, so I haven't the chance to experience these new 07s, haha.

[@orionviii]

It's not just you.

Is it just me, or does the ISL sound different from the '06 D40LFRs?
