Hi Johnny,
This one has a Detroit Diesel Series 60 DDEC III. 13 liters and dialed for 475 HP and 1600 pounds feet of torque. Chassis GVW is just under 50,000 pounds but the coach weight is way short of that, below 43,000 IIRC so it performs well. I could not keep up with the Prevost in the GMC when the bus was driven by a pro driver for the mountainous run from AZ where we purchased it and NV where we took possession. The 6 speed Allison bus transmission (different from the motorhome transmissions - more cooling capacity and larger bearings) is a big part of the performance. Sure wish we could get a 6 speed automatic in our GMCs! In the Prevost case gear 4 is 1:1 and 5 and 6 are both overdrive gears. Final drive gearing is such that even steep mountain passes can be crossed in gear 4 at around 55-60mph. It has a dual stage Jacobs brake which really hauls this thing down going down hills.
