Instead of a conventional starter motor and alternator, the hybrid pickup use a compact, 14 kW electric induction motor or starter generator integrated in a patented, space-efficient manner between the engine and transmission. The starter generator provides fast, quiet starting power and allows automatic engine stops/starts to conserve fuel. It also smoothes out any driveline surges; generates electrical current to charge the batteries and run auxiliary power outlets; and provides coast-down regenerative braking, to improve fuel economy.

The standard Vortec 5.3L V-8 engine delivers 295 horsepower (220 kW) and 335 lb.-ft. (463 Nm) of torque - the same as its non-hybrid counterpart - along with the capability of acting as a mobile power-generating station, including four 120-volt/20-amp electrical auxiliary power outlets (APO). The power outlets are located under the rear seat of the cab and in the pickup bed. Customers can conveniently operate power equipment without taking up the bed space typical portable generators would use.


GMC Sierra Classic Performance Edition

For SLE/SLT Extended Cab 2WD models, the Sierra Classic Performance Edition pairs the VortecMAX high-output Vortec 6.0L powertrain with 20-inch chrome wheels, which combine to create a powerful and road-ready Sierra Classic. This package also includes a VortecMAX door badge and engine cover, 3.73 rear axle, high-performance suspension, HD automatic transmission, HD trailering, HD oil cooler, automatic locking differential, engine oil cooling system and traction control.


Duramax 6.6L turbo-diesel

An all-new version of the Duramax 6.6L turbo-diesel V-8 engine was introduced during the '06 model year and paired with a new, Allison 1000 six-speed automatic transmission. In this configuration the engine delivers 360 hp (268 kW) at 3200 rpm and 650 lb.-ft. of torque (881 Nm) - more power with lower emissions than the previous diesel engine.

The Duramax 6.6L's horsepower and torque increase and emissions reduction are enabled by a strengthened iron cylinder block and a lower compression ratio. The lower compression reduces stress on the engine by reducing the peak cylinder firing pressure. This, in turn, allows more fuel to be burned - more fuel means more power - while the lower compression helps reduce NOx emissions. Lower compression also helps reduce noise and vibration, making it a quieter and smoother engine.

A revised variable-geometry turbocharger also enhances the driving experience of the Duramax 6.6L. Aerodynamic changes to the turbo's impellers help tailor controlled application of turbo power for seamless and immediate response at full throttle. The turbo, which spins at up to 120,000 rpm, is high-speed-balanced, reducing vibration and resonance - and contributing to the engine's overall smoothness and refinement. The revised turbo also helps reduce emissions, while maximum boost remains at 20 psi.


2007 GMC Sierra Classic Safety features

All Sierra 1500 Classic models (except 1500HD) are equipped with GM's Passenger Sensing System, which uses the latest sensing technology to turn the front passenger air bag on or off. If the sensor system detects an unoccupied front passenger seat or the presence of a smaller occupant, the front passenger air bag is designed to automatically turn off so it will not deploy in the event of a frontal collision. A status indicator on the inside rearview mirror alerts occupants that the passenger air bag is on or off. Even with this system, GM strongly recommends restraining child passengers in an appropriate child seat placed in the rear of the vehicle. Owners should never install a rear-facing infant seat in front of an active air bag. GM also recommends that all children 12 and under ride in the rear seat when possible.
