Press release

On a validation drive of the new, Chevrolet Silverado heavy-duty engineer Brent Deep a 20,000-pound (9,072 kg) trailer for 245 (400 km) along I-70 Denver and Grand Junction, and he barely touched the brakes the way.

Deep relied on the new, smart exhaust system to slow the truck/trailer on descents, helping prove the new is suitable for the most demanding It was a drive across the heart of the Mountains and some of the interstate steepest grades, with ranging from Denver’s 5,000 feet (1,525 m) to than 11,100 feet m) at the Eisenhower Tunnel.

“It some courage to leave foot off the brake, but the Silverado’s engine and Allison transmission the task with smoothness and that really impresses,” Deep. “Better still, the brake system can help brake pad life and help overheating the brakes on long

The exhaust brake system is just one of the elements that the new 2011 Silverado 2500HD and models the most capable in the They go on sale this

“We sought the input of our during the development of the 2011 HD to deliver a truck that or exceeds their every said Jim Campbell, Chevrolet manager. “It offers strength and capability including fuel economy, trailering and ratings and has more power, quicker and has lower emissions. sounds like the very of no compromises.”

The Silverado heavy-duty is broader than ever, 11 2500HD models and eight and dual-rear-wheel 3500HD models a new 3500HD Crew Cab with a cargo box. WT, LT and LTZ trim are offered, and popular features as the EZ Lift tailgate and rearview system return. All models greater capability, improved and handling and a greater feeling of control. Depending on the model:

fifth-wheel towing capacity of pounds (9,072 kg)

Segment-best towing capacity increases up to 23 with a maximum of 16,000 (7,272 kg)

Segment-best payload of 6,335 pounds (2,873 kg) on a vehicle

Segment-best Gross Weight Rating increases to pounds (12,500 kg)

Gross Weight Ratings increases up to 17 to 13,000 pounds (5,909 kg)

Axle Weight Rating by up to 25 percent to 6,000 pounds kg)

Snow plow capability is now for all 4WD cab configurations

There are also powertrains, including a new Duramax diesel/Allison 1000 six-speed that offers the exhaust system, new front and rear an improved brake system, start assist, trailer control system and more.

with all their heavy-duty these trucks are designed to be and refined, inside and out,” Campbell. “We paid attention to all the details, giving a distinctive, muscular appearance on the and a well-appointed interior with the convenience and safety features appreciate.”

Outside, the 2011 2500HD and 3500HD models are by a power dome-style hood a new, louvered design, as as a new grille and full-width chrome front bumper. A new lineup of 18- and 20-inch wheel/tire combinations is too (20-inch polished forged wheels are available on 2500HD).

and engineers left almost no unturned during the comprehensive of the trucks. Here are 11 key elements demonstrate the 2011 Silverado and 3500HD are ready for any job and any competitor:

1. New

In the quest to comprehensively redesign the HD chassis to improve durability and while also supporting capability, engineers developed 11 fully boxed frame The frames have increased sections and use more high-strength for greater durability, higher capacity and improved ride and the front sections are hydroformed.

The bending and beaming stiffness of the is increased 92 percent and 20 percent, with the fully boxed enhancing torsional stiffness by a of five. Also, larger and transmission mounts, coupled a 125-percent-stiffer front frame provide greater vibration while hydraulic body are incorporated under the cab section on and crew cab models for a more feel inside.

Engineers common customer and aftermarket when designing the new frames, adding access holes to the frame section to enable installation of fifth-wheel/gooseneck-style hitches. the frame-mounted hitch for conventional is stronger, with a box-tube It supports up to 16,000 pounds kg).

2. New and strong independent suspension

A completely redesigned front suspension system up to a 25-percent greater front weight rating up to 6,000 (2,721 kg) front gross weight rating (FGAWR) a snow plow to be used on all 4WD cab with the available snow prep package, while supporting improved ride and characteristics.

Silverado’s signature arm/torsion bar front suspension is retained, but now features new, steel upper control that are stronger and lighter their predecessors. The new lower arms are made of precision-machined iron to handle the greater Five different torsion bar support five different gross axle weight (a single torsion bar was previously for all models).

This helps the range of trim heights of models under load, enhancing appearance, handling, tire wear and alignment. The height is adjusted on each bar via a bolt, easily allowing the to be changed to account for the weight of a plow or other accessories.

The HD front suspension now uses a of urethane jounce bumpers on side, instead of one, for load management; and there’s a new shock mount attachment that’s positively connected to the with two fasteners. This eliminates squeaks and clunks, supporting higher load and increased durability.

Compared to beam-axle front suspension, the independent front suspension a better ride, more trim height control fewer parts) and greater to adjust the alignment for weight and sensitivity.

3. New asymmetrical leaf-spring suspension

Commensurate with the HD’s greater strength and is a rear suspension designed to greater loads. It features a larger asymmetrical leaf-spring that also contributes to ride and handling characteristics.

The design is derived from front and rear spring lengths, which minimize hop and enhance traction control 2500HD models feature a leaf-spring design, while models have a three-stage All models feature 3-inch-wide (76 mm) springs that are 20-percent than previous models.

The larger leaf-spring design increased rear gross weight ratings across the On the 2500HD models, the rating is pounds (2,818 kg) up from (2,765). On 3500HD models, the increases to 7,050 pounds kg) on single-rear-wheel models and 9,375 (4,261 kg) on dual-rear-wheel models the representing a nearly 14-percent over the previous 8,200-pound kg) rating.

4. Segment-leading towing and capability

Stronger frames, systems with greater ratings and enhanced powertrain contribute to the Silverado HD’s towing and payload capability. The charts included below capacities for each model configuration, but here are the key facts:

The conventional (ball hitch) rating increases to 16,000 (7,257 kg)

A Silverado 3500HD cab/long box can tow up to 20,000 pounds kg) with a fifth-wheel hitch. The Ram 3500 has a maximum rating of pounds (8,000 kg) and the 2010 F-350 is rated at a maximum of pounds (8,545 kg). It be noted that while claimed segment-leading trailering and during its recent announcement of the Super Duty models, no ratings were issued

The payload (3500HD) is 6,335 (2,873 kg) that’s nearly 11 greater than the 2010 F-350 ’s 5,730-pound kg) rating and about 24 percent than the 2010 Ram 3500’s (2,331 kg) ratings. Again, claiming segment-leading payload for the Super Duty models, did not announce the ratings

5. New 6.6L diesel and Allison 1000 combination

Helping the new 2011 HD trucks deliver their capabilities is a new version of the workhorse 6.6L diesel and Allison six-speed automatic transmission combination. The Duramax 6.6L is powerful and durable and the Allison is stronger and helps enable new including the exhaust brake Together, this improved of a proven combination is also to deliver segment-best fuel

The Duramax 6.6L’s new and improved include:

Horsepower and torque to top previous model (testing is check media.gm.com for updates)

NOx reduced at least 63 percent 2010 models

Quieter

High-pressure (30,000 psi/2,000 Piezo-actuated fuel system for fuel efficiency, improved and reduced emissions

Exhaust system that enables vehicle slowdown on downhill without actuating the brakes

catalytic reduction after-treatment using diesel exhaust (DEF) injection to provide the overall diesel characteristics and with a range of about miles (8,000 km) between DEF

Combustion and after-treatment have optimized to provide about 700 (1,125 km) between diesel filter regenerations a 75-percent over the previous system and contributor to improved fuel as the regeneration process requires fuel

B20 biodiesel capability for an alternative option

Internal revisions improve durability

With 1.3 million Duramax 6.6L produced since 2000, have proven exceptionally and dependable. The internal elements helped build its reputation are for 2011, including:

Main profiles changed to enhance oil thickness

Oil pump flow for increased pressure at low speeds

The oil circuit is changed to provide pressure at the turbo and faster oil

The connecting rods’ pin ends are to provide increased piston

New, higher-strength piston that eliminates bushings to lower reciprocating weight

An EGR bypass reduces high-mileage deposits in the cooler and EGR circuit

The Allison 1000 for 2011 is to handle the higher torque of the new 6.6L Duramax engine, also helping improve economy and provide seamless with a new exhaust brake Greater efficiency is delivered reduced “spin loss” the transmission channels more of the power to the axles, allowing it to do with less fuel.

The 1000 also features shift control with tap down shifting and a patented idle mode cab warm-up Also, the tow/haul mode shift cycling for better and improved cooling when or hauling heavy loads. The configuration retains its two overdrive for optimal efficiency.

Performance the Duramax/Allison combination is also over previous models, preliminary testing showing mph times of less than 9 and quarter-mile times of less 16 seconds in 2500HD models. about 0.3-second and 0.5-second respectively, than previous

6. Strengthened Vortec 6.0L/Hydra-Matic six-speed powertrain

The venerable 6.0L gas V-8 with variable timing returns to the new heavy-duty along with a strengthened of the Hydra-Matic 6L90 six-speed transmission. This combination excellent performance and efficiency, a greater emphasis on low-rpm

A new camshaft profile in the Vortec helps the engine produce torque lower in the rpm band, for launch feel and a greater of overall performance at higher and when towing a trailer.

The is enhanced for greater strength, and quietness via:

Adding attachment bosses to the transfer adapter (4WD models) for strength and smoother, quieter

Increasing the cross section of the transfer case adapter for strength

Adding a new, output shaft

Adding a new shield and vent hose

7. brake system

A new feature on models is an exhaust brake This driver-selectable feature the turbine control of the variable turbocharger and the compression of the engine to backpressure, slowing the vehicle applying the brakes. It is a smart integrated with the cruise feature and varies the braking to for the grade and vehicle load.

The exhaust brake system for virtually effortless driving and with seamless and quiet It also helps prolong life and prevents overheating the on long, downhill grades.

8. brakes

Brake feel and is greatly improved with the Silverado HD trucks. The standard disc system is completely to deliver smoother, more and confident-feeling performance. Four-wheel, ABS is standard on all single-rear-wheel models and a system is standard on dual-rear-wheel

The front and rear rotors are in diameter 14 inches (355 mm) and on all models to support their capacity, weight ratings and ratings, while the calipers are and stronger. The hydroboost brake calibration is revised for reduced effort and the travel of the pedal is revised for a more comfortable, feel.

Larger wheel hub and assemblies complement the new brake and the rear rotors attach to the hubs for easier servicing.

9. and capable ride, handling and

Longer wheelbases ranging 133.6 inches (3,395 mm) to inches (4,259 mm) and wider tracks enhance the ride and characteristics of the Silverado 2500HD and giving them a greater of smoothness and control.

The longer and wider tracks are complemented by the stiffer frames, new jounce shock mounts and hydraulic mounts to provide a solid, and isolated driving experience. New were specially valved to the new trucks’ weight ratings, balancing excellent ride

Also enhancing the driving is a revised steering system to support the trucks’ greater gross axle weight It includes a new, larger gear, power steering and linkages. The pumps (different for gas and diesel models) deliver pressure for reduced steering in low-speed and parking maneuvers; are also quieter.

On some the new linkages feature a compliant added at the pitman attachment to handling.

10. Comprehensive safety and technology

The 2011 Silverado and 3500HD models have a roster of safety features and technologies that include:

electronic stability control on all single-rear-wheel models

Larger, disc brakes with four-wheel ABS

A new high-strength steel frame cross member enhances safety and improves

Seat pelvic/thorax and head side air bags available on

Available rear backup

Segment-exclusive OnStar 9.0

Trailer control system on all single-rear-wheel

Hill start assist on single-rear-wheel models)

Trailer control system provides an measure of confidence when a trailer. The system senses of trailer sway and intervenes braking and/or reduced power to bring the trailer control and keep it on its intended The system will use electric brakes when a trailer is into the standard wiring of the truck and its performance requires no from the driver.

The hill assist system is automatically when sensors detect the is on grade of about 5 percent or It holds the brakes for about 1.5 or until the gas pedal is pressed, rollback it is particularly effective towing, giving the driver to switch from the brake to the gas pedal without rolling.

11. bigger, drives better, harder

From the available starting feature to the unimpeded offered by the 170-degree-opening rear doors on extended cab models, the Silverado HD models live drive better and work The interiors are refined, with quietness and attention to detail, but for working. Numerous storage provide covered access for from work gloves to

Indeed, for many owners the HDs are mobile workspaces, offering WiFi, USB connectivity, Bluetooth XM Satellite Radio and a navigation Multiple charge points multiple electronic devices to simultaneously; and when equipped the available navigation system, XM offers real-time updates of conditions (in selected areas) can help plan the most route to the job site.

Cold-weather will appreciate the Duramax quick, reliable start-up, a starting time on par with gas Its glow plug cycle is the segment’s best in all temperatures, no more than 3 seconds in as low as -20 F (-29 C). There’s also a cab feature that allows the to idle faster in low temperatures to up the interior faster.

And when on the road, the Silverado HDs take you without stopping. A new, (136 L) fuel tank is on all models and, with the fuel efficiency of the powertrains, a cruising range of up about 680 (1,090 km) with the Duramax That’s the equivalent of a trip Houston to Oklahoma City and to Dallas on a single tank.
