According to Aussie youtubes etc. the 2.8 has been tuned to actually have a bit more power and torque to its V8 4.5 diesel counterpart. The V8 has been undertuned a lot to meet emissions etc, but this can be modded to give you much more power and torque.Can't comment on the 250, but the new 70 series 2.8 is apparently faster and more powerful than the V8 diesel and essentially still running all the HD underpinnings, inc the mismatched front and back track (for reasons I can't work out!). Still reckon if they sold it here for under £50k OTR it would sell....
Agree with you Dave, Mr T should have taken this opportunity to correct the track width….Aye, I understood the background to the track differences, I was more surprised that MrT didn't sort this out on the 2.8 version as they don't need the wider track.. or maybe just widen the rear and have done with it. Seems an odd decision to leave it as it is, other than for penny-pinching reasons...
