Observed MPG?

For those who have had a little time behind the wheel of their new GV80's, what type of MPG's are you seeing in real-world driving?

Also which engine do you have and what is your ratio of City/Hwy driving?

Thanks!

Have the 3.5 Prestige. Probably doing 50/50 hwy/city right now. Getting around 17 mpg avg.
2275 miles on my 3.5 advanced plus and averaging 19.6 MPG with very little highway but lots of back country roads at 45 to 55 MPH. I got 13.3 MPG pulling my 2700 Lb fishing boat about 120 miles round trip
Finally took a road trip of 800 miles to gauge MPG performance: 3.5TT - using Midrange Fuel - 23.6 on highway (80 mph), 15 urban stop and go but 17 average. Not the greatest, but given the engine performance and power, seems acceptable.

I now have about 11K on my GV80 Presyige with 3.5. I live in a very hilly area of North Georgia and I would have to at first I was disappointed with my mileage. I was averaging about 15 MPG. When out of the hilly area and on a flat highway on cruise it went to 19 MPG. Last spring I drove from Georgia to Cape Cod Massachusetts, an 1100 mile trip. I averaged 20.5 MPG

While there, I averaged 20 or better. On the trip back to Georgia at the end of the summer, I averaged 21.7 mpg. Back in Georgia going up and down hills I back to 15-17 mpg.
Just finished a 2,700+ mile road trip, western states. From basically sea level to 11k feet elevation, a lot of our driving was at altitudes over 4k feet. We did a significant amount of cruising at 80+ (ID and UT highways are posted at 80, in some places 85), we hit some serious headwinds while climbing out of St George UT on I15. I hand calculated our mileage at 22.9 and the GV had it at 22.7 for the trip. Not at all unhappy. Gret vehicle for long distance cruising.

Interesting how close your hand calculation and the GV computed calculation were to each other.
I live in Florida so mostly flat driving and I have about 19,000 miles on my 21 Prestige 3.5. To begin with my gas mileage wasn’t very good, about 19 miles a gallon running 75 mph. Recently though, after putting some miles on my GV 80, I have been averaging 24.8 mph while running 75. Also, I have pulled an enclosed 5x10 motorcycle trailer to Utah twice in the past year. Trailer, (all aluminum) motorcycle (Harley Touring) and luggage, weight approximately 2200 lbs total. Maintaining 75mph and pulling this rig, gas mileage drops to 14.3 mph.
