Driving experience and capability

A new, Gen-IV 6.0L gasoline V-8 engine with variable valve timing and an enhanced, more powerful version of the Duramax 6.6L turbo-diesel are the engine choices for the Silverado and Sierra 2500HD and 3500HD models. Both engines offer segment-leading power and torque ratings. The gas engine is backed by a new, Hydra-Matic 6L90 six-speed automatic transmission, which features grade braking capability. Duramax-powered trucks are backed by the reknown six-speed Allison 1000 automatic transmission.

The standard engine is the new, 6.0L gas V-8. It is rated at a best-in-class 353 horsepower (233 kW) and 373 lb.-ft. of torque (506 Nm) on single rear wheel configurations.* Variable valve timing helps improve performance and fuel economy. A new, Hydra-Matic 6L90 six-speed automatic transmission is paired with the engine. This powertrain combination offers a higher maximum gross combined weight rating (GCWR) – 18,500 pounds (8,392 kg) – than previous gas-powered combinations and is the segment leader for vehicles with a small-block V-8 gas engine. The 6L90 has a wide, 6.04:1 overall ratio – including two overdrive gears – that helps deliver an excellent balance of performance and fuel economy. It also offers manual range selection and tap up/tap down control.

A cleaner, more powerful Duramax 6.6L turbo-diesel engine is available. It continues to lead the segment in power and torque, with power ratings increased to 365 horsepower (272 kW) and 660 lb.-ft. of torque (895 Nm). Upgrades to the engine and a new diesel particulate filter system help provide a 90-percent reduction in particulate matter and a 50-percent reduction in NOx (compared with current standards), meeting a new federal government mandate. All diesel manufacturers are required to meet the new emissions standard, starting in calendar year 2007.

The renowned Allison 1000 six-speed automatic transmission is partnered with the Duramax 6.6L turbo-diesel engine. It delivers good fuel economy, quietness and control. It features a class-first range selection function, which allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.

Working in concert with the powertrains are a strong chassis and responsive suspension systems. The vehicle frame is comprised of a sturdy ladder design that is reinforced with cross braces. It features a segmented design that enables easy and accurate adaptation of numerous lengths to accommodate the trucks’ five wheelbase lengths. The frame sections are joined with strong, overlapping segments that bolster overall strength and rigidity.

The strength of the frame and enhanced capabilities enabled by the powertrain systems allow the 2007 Silverado and Sierra heavy-duty trucks to offer a larger, 2.5-inch trailer hitch receiver platform. This enables the trucks to pull a segment-leading maximum of 13,000 pounds (5,897 kg) with conventional trailers. Trucks with fifth-wheel hitches can tow up to 16,700 pounds (7,575 kg), when properly equipped.

Additional features:

• All 2500HD and 3500HD models ride on a wide, 68.6-inch (1,742 mm) front track. The rear track on 2500HD trucks is 66 inches (1,676 mm); the rear track on 3500HD models is 74.7 inches (1,897 mm), giving Silverado and Sierra heavy-duty models a firmly planted feel.

• Two suspension packages: Z85 and Z71. The Z85 suspension is standard on 2WD and 4WD models; the Z71 Off Road suspension is optional and includes additional chassis and suspension equipment, including skid plates.

• A new steering control box is used with the recirculating ball steering system, delivering improved returnability for a greater feeling of control and on-center feel.

• A high capacity, four-wheel disc brake system with Hydroboost and four-wheel ABS is standard on all models. The brake system includes large-diameter front and rear disc rotors and stiff brake calipers.

All heavy-duty models are available with an integrated trailer brake controller. It is integrated with the ABS system and provides immediate and measured brake force signaling to electric-controlled trailer brake systems. There is no requirement for external and/or aftermarket brake control systems. The brake controller switch is conveniently mounted on the lower-left section of the instrument panel.

Safety details

Silverado and Sierra heavy-duty models are designed to help drivers avoid crashes and protect passengers in the event one occurs. The robust ladder frame and strong body structure provide occupant protection. The frame is designed with crush zones that crumple to absorb crash energy, while the new body structure incorporates the strategic use of high-strength steel and structural adhesives designed to help maintain passenger compartment integrity and manage energy in a crash.

Additional safety features include:

• Dual-stage frontal air bags are standard on all models.

• Segment-first front safety belt pretensioners with both front and rear crash sensing.

• A standard, high capacity four-wheel disc brake system with four-channel ABS system provides superior stopping capability.

• A new Ultrasonic Rear Parking Assist system is available and provides visual (LED lights) and audible warnings of objects behind the vehicle.

• Tire pressure monitoring system is standard on all models except Dually.

• Segment-exclusive factory-installed remote vehicle starting system is available on most models.

• Power-adjustable pedals complement increased front seat fore/aft travel to enable smaller-stature drivers to find an optimized driving position.

All retail models come standard with the OnStar Generation 7 system, including a one-year subscription to the Safe & Sound plan. The OnStar service includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen and provides remote door-unlocking service (when the vehicle is equipped with power locks).

*SAE certification. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005. This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.
