2010 SIERRA HYBRID DELIVERS 23-PERCENT IMPROVED FUEL CONSUMPTION, THANKS TO GMC'S ENGINEERING EXPERTISE
The GMC Sierra Hybrid is a powerful, full-size pickup that achieves an estimated 32-percent improvement in city fuel consumption and a 23-percent improvement in overall fuel consumption than non-hybrid models, while delivering the capability expected of a full-size truck - including a 2,767 kg (6,100-pound) towing capacity.
Partnering General Motors' patented two-mode hybrid system and a powerful 6.0L gas V-8, the Sierra Hybrid delivers highly efficient performance, including all-electric driving up to 48 km/h (30 mph). That saves fuel even when the truck is fully loaded or towing a trailer.
The Sierra Hybrid is offered in the Crew Cab body style on both 2WD and 4WD models. Each model is equipped with several standard, popular features, including StabiliTrak electronic stability control system, a locking rear axle and a trailering package. Sierra Hybrid also offers dual-stage frontal air bags and head curtain side air bags, and it is the only full-size truck with five-star side-impact ratings in federal crash tests.
Hybrid details
The Sierra Hybrid's fuel-saving performance is derived from GM's advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM's hybrid system not only enables the Sierra to launch and drive up to 48 km on electricity alone, it allows the Vortec 6.0 L V-8 engine to operate in its more economical V-4 mode for longer periods.
As part of the vehicle's emission control system, the ESS is warranted for eight years/160,000 kms.
In the Sierra Hybrid, the hybrid system itself generates the electricity used to propel the vehicle. When the brakes are applied or the vehicle is coasting, the electric motors within the hybrid system create electricity that is stored in the 300-volt battery. This stored energy moves the vehicle and the regenerative braking cycle is renewed.
The hybrid system provides seamless, dependable power on demand in an efficient package. In fact, its electric motor is less than half the size of those in single-mode hybrid systems. This technology was developed and is still used in fleets of hybrid transit buses in more than 70 North American and European cities. Scaled down for use in passenger vehicles, the two-mode system delivers fuel savings where it is needed most - in large vehicles with high levels of capability. The system was first introduced on the 2008 Yukon Hybrid. It is a core part of GM's energy diversity efforts, centered on reducing dependence on petroleum, reducing fuel consumption, reducing emissions and minimizing the automobile's impact on the environment.
Quiet and smooth
Integration of the hybrid system on the Sierra is seamless - the battery pack is beneath the rear seat - and delivers a quiet driving experience. Contributors to this include:
- New exhaust system and resonator tuned for the 6.0L engine's Active Fuel Management operation
- Additional engine intake induction tuning for reduced interior noise and pleasing sound quality
- Low-rolling resistance, "quiet-tuned" P265/65R18 tires for reduced road noise
- Electrically driven 300-volt air conditioning compressor reduces vibration and allows the standard, tri-zone HVAC system to cool the passenger compartment even when the gasoline engine is shut off
- Electrically driven 42-volt variable-assist power steering reduces vibration and provides a fuel consumption improvement by reducing parasitic losses common in belt-driven hydraulic systems
- Energy Storage System (ESS) cooling system internal fan is tuned to be quiet at low vehicle speeds.
Along with quietness, the Sierra Hybrid also delivers exceptional driving smoothness, thanks to specifically tuned shocks for its Z85 suspension and a hydraulic body mount. Located on the passenger side of the chassis, the hydraulic mount provides a dramatic improvement in highway driving smoothness, particularly on rough or choppy road surfaces.
Trailering performance
In addition to lower fuel consumption , the Sierra Hybrid's electrically variable transmission also provides tremendous trailering capability, enhancing driving smoothness and quality when towing. Towing capacity is 2,767 kg (6,100 pounds) with 2WD models and 2,676 kg (5,900 pounds) with 4WD models.
Electric drive is enabled up to approximately 48 km/h (30 mph), saving fuel even when the truck is towing a trailer.
The EVT incorporates grade braking and tap up/tap down shift control. It also benefits towing on curves or lower-speed back roads, as exceptionally smooth gear transitions eliminate the "shift shock" torque disruption that can occur during abrupt shifts, such as when slowing or braking.
In addition to the eight-year/160,000-km warranty on the Sierra Hybrid's Energy Storage System, GM's five-year/160,000-km Powertrain Limited Warranty continues to make GM a better choice for customers. GM's coverage focuses on the complete ownership experience and includes other provisions that competitors do not offer, including transferability to the next owner, more complete coverage of parts, and coverage for new and certified used vehicles. In addition, GM offers complementary courtesy transportation and roadside assistance.
