The latest Tahoe fuel economy starts from a powerful V8 engine, found in LS and LT trims, which makes the performance even more impressive. Depending on your engine choice, either 355 or 420 horsepower gets delivered to an automatic transmission. The 5.3L V8 engine uses a six-speed automatic transmission, while the 6.2L V8 combines with a 10-speed automatic. Both engines use smart Active Fuel Management technology to disable some of the cylinders while coasting, and bring them back to life when you need more power. This helps achieve the best in class Tahoe fuel economy drivers love. Best of all, the active fuel management system transitions the cylinders from active to inactive and back again so smoothly that you might not even notice it’s happening.

Both combinations of engine and transmission get unbeatable mileage for every gallon of gas when compared to other SUVs with this size and capability. This is especially impressive considering that the Chevrolet Tahoe is a truck-based SUV. The United States Department of Energy reports the following official estimates for the 5.3L engine and six-speed transmission:

  • 23 miles per gallon highway
  • 16 miles per gallon city
  • 19 miles per gallon combined

Those numbers are for the two-wheel drive option, and upgrading to four-wheel drive only shaves off one mile per gallon. The 6.2L engine offers even more power and retains an impressive efficiency.

  • 23 miles per gallon highway
  • 14 miles per gallon city
  • 17 miles per gallon combined

Thanks to the added power of the larger engine, this mileage stays almost completely consistent with four-wheel drive. The 6.2L Tahoe (2018) engine only loses one mile per gallon highway when upgrading to four-wheel drive, and it keeps the same city and combined mileage.
