City and Highway MPG
The 2021 GMC Sierra V6 Diesel stands out with its fuel efficiency ratings that are commendable for a truck of its size and capability. For city driving, the Estimation lands around 20 MPG. This figure, while not astonishing, is noticeable for a full-size pickup and caters well to those who primarily navigate urban landscapes. On the flip side, when you hit the highway, the Sierra excels, reaching approximately 23 MPG.
Understanding the nuances of these figures is essential. The urban environment presents challenges: frequent stops, variable speeds, and the inherent weight of a truck can affect performance.
