And yes I did record a Next Gen CE today (finally, along with a 2024 Blue Bird Vision though I won't post its audio here cuz it was just driving by, so y'all might be confused), and in fact, I actually recorded 2 of them (though unfortunately after I posted one of them onto my YT channel, I discovered that the audio didn't record, which made me sad, but at least it recorded in another video of another 3rd Gen CE). Also, if the engine on the New Flyer bus I rode is not a Cummins ISB6.7, please let me know and I'll move the sound to a different project. Cuz those engines sound different on city buses compared to school buses and Freightliner and International shuttle buses due to the A/C growl. But the reason I say it's an ISB6.7 is because it sounded more like one than an ISL9, cuz the ISL9 has a more aggressive takeoff sound along with a whine, plus the idle would've sounded more similar to a T444E. The ISB6.7 on the city buses sound like a 5.9 Cummins in the idle, and that's really all I could tell. FAXVIN doesn't show anything for that license plate I tried to look up. Ignore the music and kids talking in the background, btw, and just enjoy the sound of the engine and axle noise (and no that was not on the same bus where I got mocked on over a stop request, cuz the bus I got bullied on was a Ford).
Credits: * IC Bus for the image. I'm using a picture of a 3rd Gen CE cuz I recorded 2 of those today. I think you can hear the idle better on the 3rd Gen from the acceleration though. I might get better audio sometime.
