Chevrolet Tahoe Hybrid
According to Design Manager David Smith, he and his team gave the Chevy Tahoe Two-mode Hybrid a slightly different look to go with its hybrid powertrain, while still ensuring that everyone would know it was a Chevy. The Tahoe Two-mode Hybrid (also known as a full hybrid) is has a lower stance in the front and has additional aerodynamic features  compared to the non-hybrid Tahoe.
The Vortec V8-powered hybrid combines GM's Active Fuel Management technology (Cylinder Deactivation) with a hybrid-electric drive system developed by a GM, BMW, and DaimlerChrysler partnership, and based on the technology in GM's hybrid transit buses. The result is said to be a 25 percent improvement in composite fuel efficiency.
Said Tom Stephens, group vice president, GM Powertrain, "The Tahoe Two-mode Hybrid delivers on GM's commitment to apply advanced technologies where we will realize the most fuel savings."
The two-mode is patented hybrid technology which maximizes efficiency for city and highway driving. In the first mode, at low speeds, the vehicle can operate in one of 3 ways: electric only, engine power only or in any combination of engine and electric power. The second mode combines electronic controls, such as Active Fuel Management (Displacement on Demand), cam phasing, and late-intake valve closure, allowing even more efficient engine operation.

Special features, including prominent hybrid badges and a Glacier Gold exterior finish, complete the look. The hood and liftgate are made of aluminum to keep the weight down, and the leading edges of the hood have been altered for better aerodynamics. The Tahoe Two-mode Hybrid keeps the Chevy dual-port grille with "bowtie", but has larger intake to accommodate the hybrid powertrain's higher airflow requirement for cooling. The front and rear fascias are angled in slightly and the running boards are flared in front for better aerodynamic performance.
Other aerodynamic features include:
- Sharpening of the D-pillar rearward (including the tail lamps)
- A center high mounted stop light detail spoiler over the rear liftgate
- A panel under the back of the vehicle to facilitate airflow.
- Lightweight, aero-efficient wheels with low rolling-resistance tires
