subject: The 2010 Gmc Sierra 1500 Goes Green With A Hybrid Engine [print this page] The 2010 GMC Sierra 1500 Hybrid is mostly unchanged from the 2009 model. The large-cab pick-up features a 4-door design and seats 6 inside. The rugged body design is matched by the Autotrac 4-wheel drive that can remain engaged on any surface but has a low gear that can be activated on rough terrain off-road. The only available transmission for the 2010 GMC Sierra Hybrid is a continuously variable automatic.
The sophisticated technology of the 2010 GMC Sierra Hybrid's engine system allows for a 40 percent overall increase in fuel efficiency. The dual engine system of the hybrid uses a standard combustion power plant for acceleration and high speed while two electric motors handle sustained and low speeds. The standard engine is a Vortec 6.0 liter V8 with active fuel management. The active fuel management system allows the engine to run smoothly while firing on only 4 cylinders instead of the full 8. This provides additional fuel economy and as it shifts modes the action is so smooth as to be undetectable.
Together, the dual gasoline engine system churns out 332 horsepower with a 6,100 lb. towing capacity using rear-wheel drive and 5,900 lb capacity if using 4-wheel drive. With 367 lb/ft of torque, the 2010 GMC Sierra 1500 Hybrid is a workhorse ready for action. The two electric motors provide an additional 80 horsepower each. Some complain that the acceleration pauses unnaturally as the electric motors start the wheels rolling and then the gasoline engine kicks in. However, those who appreciate the fuel economy of the hybrid system are quick to note that with a light touch, the 2010 GMC Sierra Hybrid can go from 0 30 mph purely on the electric engine, never using even a single drop of gas.
