Ngl, that engine sounds really good with that axle noise! I even tried matching my voice perfectly with it (worked for that Cummins B6.7 engine, but for the axle noise, I sounded more like a 1st Gen CE with a T444E). lol Diesel-Electric Hybrid, btw. Meaning there’s a diesel engine paired with an electric motor. I also got fooled by the bus number, btw, so I thought I was riding a 2011, but I was actually riding a 2021. (Again, still trying to get familiar with public transit as much as I’m familiar with school buses. lol)
