Towing 63 mph I’m at 1750 in 5th and putting out 600 Nm (110 Kw) or 1432 in 6th putting out 733 Nm (110 Kw) and getting the 9 mpg.
70 mph empty we are both at 1594 in 6th getting 18 mpg putting out 333 Nm. (55 Kw)
Pulling a 7% grade I’m able to do 45 mph at 2170 rpm putting out 1277 Nm (290 Kw) and according to the bsfc map I should be using 205 g/kwhr which would put me at 2.44 mpg and again you’re not going to do any better.
Edit: I'm barely into the bottom of the dark blue at 63 mph/1750rm and 600 Nm ... so probably 200 g/kwhr 9.22 mpg
just outside the dark blue at 1432 rpm in 6th and 733 Nm
.... so maybe 205 g/kwhr or 9 mpg
At 63 mph your at 1569 rpm in 8th and 669 Nm. So 195 g/kwhr/9.46 mpg
