bbigrig Posted August 28, 2014 Share Posted August 28, 2014 That and the C denotes Maxicruise ECM programming rather then the 505 Econodyne that was the only available Mp8 505 rating.

LSI Posted August 29, 2014 Share Posted August 29, 2014 wonder how fuel mileage will be? Quote Link to comment https://www.bigmacktrucks.com/topic/36799-mp-8-505/#findComment-257695 Share on other sites More sharing options...
RowdyRebel Posted August 29, 2014 Share Posted August 29, 2014 You could get the MP8 as a 505E, 505C, or 505M if you wanted. The 505E+ was the only 505 HP version to carry the "+" designation up until now. I'd like to see the 505M get it, though...

Mackpro Posted August 29, 2014 Share Posted August 29, 2014 His 2012 had 505 with Mack 310 trans and 3.42 rears. His 2015 has the 505+, same Mack T310 but 3.21 rears, His overall MPG average has jumped 1 mile per gallon over his 2012. I think he is at 7.1 overall . This is a daycab that pulls all kinds of different trailers and has no MPH limit on the throttle pedal but is driven by the same person/owner. I'll try to get get a print out of the trip MPG when he is here next.
