General Motors introduces its all-new, 2007 GMC Sierra – comprehensively redesigned pickup that incorporate new exterior and interior design, and powertrain, chassis and safety systems. The vehicle take GM’s truck legacy to a new level. Sierra leads the segment in performance, efficiency, capability, refinement and safety. The new truck offers more power and better fuel economy than the vehicle that replaced.

GMC Sierra is offered with three cab styles, three cargo box lengths and several specially tuned suspensions. All have distinct identities, including brand-exclusive sheet metal and design cues yet share fundamental traits that support segment-leading capability, quality and performance.

The broad range of configurations and models gives customers tremendous choice when selecting a vehicle to suit their needs, particularly with the heavy-duty models, which some competitors simply do not offer. Capability also is unmatched, with a strengthened chassis and enhanced towing package enabling the light-duty segment’s best towing capacity of 10,500 pounds (4,763 kg).

GMC Sierra light-duty models will arrive in the fourth quarter of 2006. Sierra heavy-duty models are available in the first quarter of 2007. The heavy-duty trucks offer new sleek designs and spacious interior features like light-duty models, but with increased capability – including more powerful gas and diesel engines.

Sierra is sleeker and more aerodynamic, including a faster, 57-degree windshield angle, reducing wind noise and improving fuel economy. Wider, segment-leading front and rear tracks and a tailored wheel-to-body relationship provide a stance that is both muscular and agile. The truck is more refined looking, too, with doors that extend over the rockers for a smooth, uninterrupted look, and lamps that have a jeweled appearance. Tolerances between panels are greatly reduced – including a 50-percent reduction in the space between the cab and cargo box.

The all-new GMC Sierra is quieter, more spacious and refined inside, with increased passenger comfort and storage space. Sierra features a new and distinct interior design that reflects its respective brand identity, including specific trim, appointments and gauge cluster appearance.

The fourth generation of the legendary small-block V-8 engine family is the power behind GM’s all-new full-size trucks, delivering segment-leading horsepower and fuel economy through advanced technology such as Active Fuel Management (AFM) and variable valve timing (VVT). A FlexFuel engine is available – and partnered with fuel-saving AFM – giving customers the choice of powering their truck with E85 ethanol, gasoline or a combination of both fuels.

GM’s fuel-saving Active Fuel Management bolsters the trucks’ capability with the segment’s best fuel economy. Highway fuel economy for models equipped with the 5.3L AFM V-8 now are estimated at more than 20 mpg for both 2WD and 4WD models.
