Detroit DD13 vs Volvo D13 for Highway Express

Which is better if you want to run long-haul highway express bus into Commiefornia - Detroit DD13 or Volvo D13? Both with Allison B500R with Jake Brake.

Outside Commiefornia I prefer pre-EGR.

 

Wow, is DD13 really that much better? If it's good for a reefer truck it's probably good for a bus because reefers usually don't need to tug heavy over hills.

 

DD13 for the win, then!

 

D13 lasts longer than DD13? Hmm, that might be a consideration. Could be doing up to 300k a year, though probably less. Significantly more mileage than charter buses because this would be regular route long-haul.

The DD13 coach seats up to 60, and the D13 coach up to 56 passengers, but the D13 coach can be found on the used market for much less whereas the DD13 coach is pretty much only available as new order.

What about MPG highway?

 

Well, DD13 won poll by landslide. Any objections?

 

Transmission is the same; it's Allison B500 for all of them. Probably a 2010 or 2011 compliant in CA with a EPA2010 engine. No gliders in coach industry. Almost exclusively for highway regular route.
