🧠 Notes

• The 2026 Acadia uses a single 2.5 L turbocharged four-cylinder engine paired with an 8-speed automatictransmission across trims. 

• Fuel economy is generally higher on the highway (27 MPG FWD) due to steady speeds and aerodynamics, while city driving with stop-and-go traffic yields lower MPG. 

• Real-world fuel economy can vary with trim level, payload, driving habits, and conditions — owners often report highway figures in the mid-20s on relaxed cruising.

If you want, I can also calculate approximate driving range per tank based on these mpg figures and the Acadia’s fuel tank capacity.
