General Motors Corp. announces pricing for the ’09 Chevrolet Silverado and GMC Sierra 2-Mode Hybrid fullsize pickups, as well as pricing on its all-new Pontiac G3 hatchback.

The auto maker also says it will tweak the Pontiac G6 lineup for the new model year.

The Silverado hybrid will start at $38,995, including a $975 destination charge, for 2-wheel-drive models. The Sierra starts at $39,365, including a $975 destination charge, for 2WD models. Higher trim levels of the Silverado and Sierra, which include items such as leather-trimmed seats and navigation system, are priced at $45,130 and $45,500, respectively.

The pricing does not reflect a $2,200 federal tax credit customers may apply for because the pickups are hybrids. Production begins next month at GM’s Oshawa, ON, Canada, assembly plant, and hybrids arrive at dealer showrooms in early 2009.

GM’s 2-Mode hybrid system combines a 6.0L V-8 engine with an electrically assisted transmission. The trucks can travel on electric power only at speeds of up 30 mph (48.3 kph) and use cylinder deactivation at higher speeds, but still tow as much as 6,100 lbs. (2,767 kgs).

The Environmental Protection Agency rates fuel economy for 2WD models at 21/22 mpg city/highway (11.2-10.7 L/100 km), while 4-wheel drive models achieve an estimated at 20 mpg (11.8 L/100 km) in city and highway driving.

That mileage, combined with a 26-gallon (98 L) fuel tank, provides the pickups with a cruising range of more than 500 miles (804.5 km) on 2WD drive models and more than 470 miles (756.4 km) with 4WD models, GM says.

The pickups represent the third application of GM’s 2-Mode hybrid system. The system also appears as an option on its fullsize SUVs. The Saturn Vue midsize cross/utility vehicle will receive a version of the technology next year.

GM also announces pricing on the ’09 Pontiac G3, an all-new hatchback based on the same subcompact platform shouldering the Chevy Aveo. The G3 will start at $14,995, including a $660 destination charge. GM says the G3 achieves an EPA-estimated 34 mpg (6.9 L/100 km) on the highway.

GM additionally announces midyear enhancements to its ’09 Pontiac G6 lineup. Changes include more aggressive exterior styling, an upgraded instrument panel design and first-time availability of a 2.4L I-4 engine in coupe models. The 4-cyl. mill achieves 33 mpg (7.1 L/100 km) on the highway, GM says.

GM is adding E85-capability to all G6 body styles with a 3.5L V-6 at no cost.

Pricing for a 4-cyl. G6 coupe with a 6-speed automatic transmission starts at $22,890 and includes a $670 destination charge. A similarly equipped G6 sedan starts at $23,875. A G6 sedan equipped with the E85-capable 3.5L engine bases at $24,125, while the GT coupe starts at $25,280.

The G6 retractable-hardtop convertible begins at $32,970, while a “value-priced” G6 base sedan with a standard equipment package starts at $19,945, GM says.

The enhanced G6 lineup will begin arriving at Pontiac dealers in January.
