What is E85?
E85 is the term for motor fuel blends of 85 percent ethanol and just 15 percent gasoline. E85 is an alternative fuel as defined by the U.S. Department of Energy. Besides its superior performance characteristics, ethanol burns cleaner than gasoline; it is a completely renewable, domestic, environmentally friendly fuel that enhances the nation's economy and energy independence.
Today, the U. S. imports more than half of its oil, and overall consumption continues to increase. By supporting ethanol production and use, U.S. drivers can help reverse that trend. 85 percent ethanol can reduce pollution. Government tests have shown that E85 vehicles reduce harmful hydrocarbon and benzene emissions when compared to vehicles running on gasoline. E85 can also reduce carbon dioxide (CO2), a harmful greenhouse gas and a major contributor to global warming.
Although CO2 is released during ethanol production and combustion, it is recaptured as a nutrient to the crops that are used in its production. Unlike fossil fuel combustion, which unlocks carbon that has been stored for millions of years, use of ethanol results in low increases to the carbon cycle.
Ethanol also degrades quickly in water and, therefore, poses much less risk to the environment than an oil or gasoline spill.
Hybrid Design Vehicles
Silverado Hybrid
10 percent better fuel economy than the conventional V8 engine. A battery stores energy and provides power to run the wheels in low-demand situations, improving fuel economy 10 percent, without compromising performance.
The Single Mode Hybrid system in the Silverado gets more miles from each gallon of gas by capturing energy through regenerative braking, shutting the engine off at low vehicle speeds or idle and shutting the fuel off instantly any time the truck is coasting or braking.
Tahoe Hybrid
When combined with Active Fuel Management, the two-mode hybrid enables a composite fuel efficiency improvement of 25 percent.
The Dual Made Hybrid system in the Tahoe uses an electrically variable transmission with two hybrid modes of operation that optimize power and torque for various driving conditions. The first mode is used for low speeds and light loads, while the second mode is primarily used at highway speeds.
What is a Hybrid?
A hybrid propulsion system uses two sources of power to move a vehicle - an internal combustion engine and electric motors. The engine charges the electric motors' batteries and their load is then reduced by the motors. This allows the engine to run more efficiently using less fuel and producing fewer emissions.
