Chevrolet, which commands the industry’s highest fuel economy in full-size pickup trucks and SUVs, is committed to achieving fuel economy and environmental technology leadership in every segment in which it competes. To do this, Chevy is incorporating improvements to the internal combustion engine such as Active Fuel Management, along with six-speed transmissions; gas-electric hybrids and, in the future, electrically driven vehicles.
Active Fuel Management can enhance fuel economy by up to 12 percent, depending on the vehicle and driving conditions. It automatically and seamlessly deactivates half of an engine’s cylinders in low-demand situations – such as when idling in rush-hour traffic or cruising on a flat highway – and reactivates them when full power is needed. Find fuel-saving AFM on these 2008 Chevys: Avalanche, Silverado, Suburban, Tahoe, Tahoe Hybrid and TrailBlazer (5.3L V-8 plus Vortec 6.0L V-8 for Silverado and Tahoe Hybrid); and Impala and Impala SS (3.9L V-6 and 5.3L small-block V-8).
In North America, Chevy features seven models that achieve EPA fuel economy of 30 or more miles per gallon on the highway, even under the new, tougher 2008 EPA computation.
