Took a 230 miles trip today - Fort Collins to Winter Park and back again. I (mostly) limited my speed to about 78MPH. This trip involves quite a climb along I70 west up to Empire, and then up and over Berthoud Pass (11,307 feet) to Winter Park. Avg. MPG for the trip was 18.1, which I think is exceptional.
Also, I was quite pleased with the way the descent system works. This made flying down steep sections of I70 going east a breeze. A little tap on the brake at high speeds, with your foot off the pedal, is all it took to get a downshift to 5th or 4th. I also noticed that you do NOT always have to tap the brake to get the tranny to shift into a lower gear when in descent mode. I make this trip frequently in the Winter months (season pass to Winter Park), either in my truck, our Acura MDX or one of our BMW sedans. In the 08 Duramax and the Acura, I always place the tranny into "M" manual mode and manually shift the tranny into lower gears to take a little load off the brakes on steep descents. With the descent system in the Ford, the manual effort is almost entirely unnecessary.
BTW, this Scorpion motor kicked *** going up and over Berthoud pass - I was the aggressor going up in both directions, negotiating around the twisties and gunning the big motor in 3th nd 4th gear, passing essentially every vehicle making the climb! I am not a crazy driver, the truck just has the power, and I was very impressed with the handling through the switchbacks. And, after all this, I averaged 18.1 MPG for the trip!
Final note - there was a "hot rodded" Black smoker Duramax (had a huge side exhaust pipe and she was making some noise) that flew around me when beginning one of the longest climbs on I70 eastbound - I know he saw me as I saw him coming after me in my rearview mirror. So, when he went around me (and several others) on this 4 lane section, I decided that I had no need to race him or anything stupid, but I thought, "I will just get right up behind him (4 or 5 lengths) and show him that this Ford is one vehicle he is not going to just walk away from!" I held right behind (fairly easily I might add) all the way up this long step section of I70. This truck can move!
