Despite these substantial updates, the fuel tank capacity remained unchanged. This model year also saw improvements in fuel efficiency due to better aerodynamics and engine enhancements.
Active Fuel Management Technology
One of the most significant advancements in this period was the introduction of Active Fuel Management technology.
This system allowed the engine to operate on fewer cylinders under specific conditions, thereby improving fuel economy.
This technology, combined with the consistent 26-gallon tank, allowed the Tahoe to achieve better mileage, especially on highways.
Hybrid Introduction
Towards the end of this decade, Chevy introduced a hybrid version of the Tahoe. While the hybrid had a different fuel economy profile, the gas tank size for the standard models remained at 26 gallons.
