I took a 21 Tahoe 5.3 on a test drive. On the interstate at 65 to 70 but only for a few miles it indicated 19 MPG. What surprised me was that taking country roads on my return the average increased to 23 or 24 MPG. My guess is that the new fuel management and 10 speed transmission are real improvements and seamless but there is no helping the fuel mileage at highways speeds with the added size and weight.
Also, I recently drove a new Expedition in a similar test. It indicated 23 MPG on the highway but began falling on stop and go traffic during the return trip not surprising. Not really apples to apples except for the highway portion where mild wind might have hindered the Tahoe and aided the Expedition somewhat though not to the extent I was seeing.
Other notes from my test drive of the LT Tahoe. If you don't use phone apps or have navigation that big monitor growing out of the dash is wasted real estate. Salesman pushed the cargo light on and the whole fixture moved. Vinyl in cargo area seemed thin and flexible compared to my 12 which I had considered too flexible but in comparison much better than the 21. It was fun to drive, nice and smooth.
