I just traded my 2019 GMC 1500 Denali at 95k miles for a 2021 model equipped similarily with 32k miles. (I lost some cameras, but gained the adaptive cruise control option.) My 2019 overall got 19 mph regularly, and 23 on interstate trips (daily). And THE BEST for 25 miles was 32mpg; 28 mpg for the 50 mile interval and 23 mpg on the 400 mile trip interval. I was very pleased and therefore upgraded to the same just 2 years newer and the lower mileage bc during construction season I'm traveling 150 to 200 miles per day. On my test drive, I noted that the 2021 showed much lower mpg for those same intervals. And the Trip 2 odometer memory was for the life of the vehicle (32,777 miles) and was only 15.5 mpg. I still purchased the 2021 under the assumption that the previous owner drove local in stop/go traffic with very little interstate mileage. The salesman who took it on trade for a new 2024 indicated it was an older gent who averaged less than 10k miles per year, bolstering assumption. My point here, is to show my 2019 experience for others to see. And, that once I season this 2021 to my driving habits I'm expecting that the 2021 mpg will improve closer to my previous experience given its the same 6.2L and 10 speed tranny for the same crew cab short bed truck.
