2017 Express with 2.8 Duramax?

[zuren]

Posting to subscribe to this thread, and see if any more info has come out regarding the Baby Duramax in the GM vans? I didn't realize they began offering this engine choice.

Is the number I'm seeing for fuel economy accurate - about 28 MPG on the highway?

I am debating my own van situation. Now with a 3 yr. old and a another kid on the way, the distance of the sofabed from the front seats is a problem; the front passenger cannot easily reach over the seat and help a young child. I'm considering the addition of a middle seat (eliminating the RB50 layout; most likely 2 Sienna seats) or considering the age and other issues developing with my van (167,000 mi., bad GM paint is peeling), is it time to look at another rig in a passenger configuration?

That's higher than the Colorado is rated for, so it's probably not realistic to expect 28 MPG from a bigger and heavier rig.

Published numbers for the Colorado/Canyon are 28 MPG, but real world seems to be closer to 30 MPG:

I get 20-22 MPG on the highway in my 5.3L with 3.42 gears, 4L60e tranny, AWD/4x4 hardware, and A/T tires rolling at 65 MPH. It would not surprise me to see 26+ MPG out of the diesel with the same gears, 8 speed tranny, and 2WD, but hard numbers have been ellusive.

FWIW, Chevy Colorado owners with the 2.8L Duramax, report the Fuelly about 24mpg collectively.

The downside is did the owner's calculate those mpg figures, or rely on overly optimistic onboard displays?
