Chevrolet Tahoe HybridThe Chevrolet Tahoe Hybrid represents General Motors' unique hybrid strategy when compared to much of the competition. Unlike hybrid systems from most other manufacturers, the Tahoe Hybrid system is mated to a powerful V8 engine. The powerful gasoline engine means that the Tahoe Hybrid is capable of towing up to 6,200 lbs. It will be available with both RWD and 4WD. 
There are two electric motors housed within the transmission and a 300-volt battery is positioned under the middle row seats. GM calls this system a two-mode hybrid. In low load driving (city speeds) engine power is supplemented with one or two of the electric motors and shuts off the gasoline engine when the vehicle comes to a stop. With a gentle foot the Tahoe Hybrid can get up to 30 mph with the electric motors alone. The system is set-up to minimize fuel consumption by running the engine at a constant speed with the electric motors providing additional power when needed. On the highway, the electric motors are only used about 25% of the time and most of the power comes from the gasoline engine. Gains in fuel efficiency occur at highway speeds due to increased aerodynamic performance with the Tahoe Hybrid achieving 0.34cd versus 0.39cd for a conventional Tahoe. In addition, GM has outfitted the Tahoe Hybrid with their Active Fuel Management system which can shut down four cylinders at highway speeds. The end result is significantly better fuel economy than a conventional Tahoe. According to GM, the Tahoe Hybrid is rated at 21 MPG city, 22 highway for RWD models, and 20 city, 20 highway for 4WD. This represents about a 25% improvement over a regular Tahoe. Looking for more information on the Chevrolet Tahoe Hybrid ?
