2009 SILVERADO HYBRID DELIVERS 25-PERCENT IMPROVED FUEL ECONOMY AND DELIVERS CHEVY’S RUGGED CAPABILITY

The 2009 Chevrolet Silverado Hybrid is a powerful full-size pickup that achieves 40-percent greater city fuel economy and a 25-percent improvement in overall fuel economy while delivering the capability expected of a full-size truck – including a 6,100-pound (2,767 kg) towing capacity.

Partnering General Motors’ patented two-mode hybrid system and a powerful 6.0L gas V-8, the Silverado Hybrid delivers highly efficient performance, including all-electric driving up to 30 mph (48 km/h). That allows fuel savings to be realized even when the truck is fully loaded or towing a trailer.

EPA-estimated fuel economy for 2WD models is 21 mpg in the city and 22 on the highway; 4WD models are estimated at 20 mpg in both city and highway driving. That mileage, combined with the Silverado Hybrid’s 26-gallon (98 L) fuel tank, delivers a cruising range of more than 500 miles with 2WD models and more than 470 miles with 4WD models.

“The Silverado Hybrid’s combination of efficiency and capability make it a no-compromises truck for customers who work and play hard, but want greater fuel economy,” said Ed Peper, Chevrolet general manager.

The Silverado Hybrid goes on sale in the first quarter of 2009. It 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. Silverado 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 Silverado 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 in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM’s hybrid technology system not only enables the Silverado to launch and drive up to 30 mph on electricity alone, it also allows the Vortec 6.0L 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/100,000 miles.

With GM’s two-mode hybrid system, the electric power used to propel the vehicle is generated by the hybrid system itself. 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 is used to move the vehicle and the regenerative braking cycle is renewed.

The two-mode 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 two-mode system was first introduced on the 2008 Tahoe Hybrid. It is a core part of GM’s energy diversity efforts, which are centered on reducing dependence on petroleum, improving fuel economy, reducing emissions and minimizing the automobile’s impact on the environment.

With the fuel savings of the hybrid system and Silverado’s 26-gallon (98-liter) fuel tank, the Silverado Hybrid has a cruising range of more than 500 miles (800 km).

Quiet and smooth

Integration of the hybrid system on the Silverado is seamless – the battery pack is located beneath the rear seat – and delivers a quiet driving experience. Contributors to this include:

Along with quietness, the Silverado Hybrid also delivers exceptional driving smoothness, thanks to specifically tuned shocks and a new 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 increased fuel economy, the Silverado Hybrid’s electrically variable transmission also provides tremendous trailering capability, enhancing driving smoothness and quality when towing. Towing capacity is 6,100 pounds (2,767 kg) with 2WD models and 5900 pounds (2,676 kg) with 4WD models.

Electric drive is enabled up to approximately 30 mph (48 km/h), even when towing, allowing fuel savings 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/100,000-mile warranty on the Silverado Hybrid’s Energy Storage System, GM's Five-Year/100,000 Mile 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 programs such as courtesy transportation and roadside assistance.
