BRING IT ON – 11 WAYS THE NEW 2011 CHEVROLET SILVERADO HEAVY-DUTY TRUCKS PROVE THEY’RE READY FOR ANY JOB OR COMPETITOR

CHICAGO – On a recent validation drive of the new, 2011 Chevrolet Silverado heavy-duty trucks, engineer Brent Deep towed a 20,000-pound (9,072 kg) trailer for 245 miles (400 km) along I-70 between Denver and Grand Junction, Colo. – and he barely touched the brakes the entire way.


Deep relied on the Silverado’s new, smart exhaust brake system to slow the truck/trailer combination on descents, helping prove the new system is suitable for the most demanding conditions. It was a drive across the heart of the Rocky Mountains and some of the interstate system’s steepest grades, with altitudes ranging from Denver’s approximately 5,000 feet (1,525 m) to more than 11,100 feet (3,400 m) at the Eisenhower Tunnel.

“It takes some courage to leave your foot off the brake, but the Silverado’s Duramax engine and Allison transmission perform the task with smoothness and confidence that really impresses,” said Deep. “Better still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on long descents.”

The exhaust brake system feature is just one of the elements that makes the new 2011 Silverado 2500HD and 3500HD models the most capable in the industry. They go on sale this summer.

“We sought the input of our customers during the development of the 2011 Silverado HD to deliver a truck that meets or exceeds their every need,” said Jim Campbell, Chevrolet general manager. “It offers greater strength and capability – including class-leading fuel economy, trailering and payload ratings – and has more power, accelerates quicker and has lower emissions. That sounds like the very definition of no compromises.”

The Silverado heavy-duty lineup is broader than ever, with 11 2500HD models and eight single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box. WT, LT and LTZ trim levels are offered, and popular features such as the EZ Lift tailgate and rearview camera system return. All models bring greater capability, improved ride and handling and a greater feeling of driver control. Depending on the model:

-Segment-best fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
-Segment-best conventional towing capacity increases up to 23 percent, with a maximum of 16,000 pounds (7,272 kg)
-Segment-best payload capability of 6,335 pounds (2,873 kg) on a complete vehicle
-Segment-best Gross Combined Weight Rating increases to 27,500 pounds (12,500 kg)
-Gross Vehicle Weight Ratings increases up to 17 percent to 13,000 pounds (5,909 kg)
-Front Axle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
-Snow plow capability is now enabled for all 4WD cab configurations

There are also enhanced powertrains, including a new Duramax 6.6L diesel/Allison 1000 six-speed transmission that offers the exhaust brake system, new front and rear suspensions, an improved brake system, hill start assist, trailer sway control system and more.

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

Outside, the 2011 Silverado 2500HD and 3500HD models are distinguished by a power dome-style hood with a new, louvered design, as well as a new grille and full-width chrome steel front bumper. A new lineup of 17-, 18- and 20-inch wheel/tire combinations is featured, too (20-inch polished forged aluminum wheels are available on 2500HD).

Designers and engineers left almost no bolt unturned during the comprehensive redesign of the trucks. Here are 11 key elements that demonstrate the 2011 Silverado 2500HD and 3500HD are ready for any job and any competitor:

1. New frames

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

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

Engineers addressed common customer and aftermarket uses when designing the new frames, including adding access holes to the rear frame section to enable easier installation of fifth-wheel/gooseneck-style hitches. Also, the frame-mounted hitch for conventional trailering is stronger, with a box-tube design. It supports up to 16,000 pounds (7,257 kg).

2. New and strong independent front suspension

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

Silverado’s signature short-long arm/torsion bar front suspension design is retained, but now features new, forged steel upper control arms that are stronger and lighter than their predecessors. The new lower control arms are made of precision-machined cast iron to handle the greater loads. Five different torsion bar rates support five different front gross axle weight ratings (a single torsion bar was previously used for all models). This helps stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.

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

Compared to competitors’ beam-axle front suspension, the Silverado’s independent front suspension provides a better ride, more accurate trim height control (with fewer parts) and greater flexibility to adjust the alignment for weight and tire sensitivity.

3. New asymmetrical leaf-spring rear suspension

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

The asymmetrical design is derived from unequal front and rear spring half lengths, which minimize axle hop and enhance traction control efficiency. 2500HD models feature a two-stage leaf-spring design, while 3500HD models have a three-stage design. All models feature 3-inch-wide (76 mm) leaf springs that are 20-percent wider than previous models.

The larger leaf-spring design supports increased rear gross axle weight ratings across the board. On the 2500HD models, the rating is 6,200 pounds (2,818 kg) – up from 6,084 (2,765). On 3500HD models, the rating increases to 7,050 pounds (3,204 kg) on single-rear-wheel models and 9,375 pounds (4,261 kg) on dual-rear-wheel models – the latter representing a nearly 14-percent increase over the previous 8,200-pound (3,727 kg) rating.

4. Segment-leading towing and payload capability

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

-The maximum conventional (ball hitch) towing rating increases to 16,000 pounds (7,257 kg)
-A Silverado 3500HD crew cab/long box can tow up to 20,000 pounds (9,091 kg) with a fifth-wheel hitch. The 2010 Ram 3500 has a maximum rating of 17,600 pounds (8,000 kg) and the 2010 Ford F-350 is rated at a maximum of 18,800 pounds (8,545 kg). It should be noted that while Ford claimed segment-leading trailering and payload during its recent announcement of the 2011 Super Duty models, no towing ratings were issued
-The maximum payload (3500HD) is 6,335 pounds (2,873 kg) – that’s nearly 11 percent greater than the 2010 Ford F-350’s 5,730-pound (2,604 kg) rating and about 24 percent more than the 2010 Ram 3500’s 5,130-pound (2,331 kg) ratings. Again, while claiming segment-leading payload for the 2011 Super Duty models, Ford did not announce the ratings

5. New 6.6L Duramax diesel and Allison 1000 six-speed combination

Helping the new 2011 Silverado HD trucks deliver their best-in-class capabilities is a new version of the workhorse Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination. The Duramax 6.6L is more powerful and durable and the Allison 1000 is stronger and helps enable new features, including the exhaust brake system. Together, this improved version of a proven combination is also expected to deliver segment-best fuel economy.

The Duramax 6.6L’s new and improved features include:

-Horsepower and torque expected to top previous model (testing is ongoing – check media.gm.com for updates)
-NOx emissions reduced at least 63 percent over 2010 models
-Quieter operation
-High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
-Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes
-Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills
-Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel
-B20 biodiesel capability for an alternative fueling option
-Internal revisions that improve durability

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

-Main bearings’ profiles changed to enhance oil film thickness
-Oil pump flow increased for increased pressure at low speeds
-The turbocharger’s oil circuit is changed to provide increased pressure at the turbo and faster oil delivery
-The connecting rods’ pin ends are modified to provide increased piston support
-New, higher-strength piston design that eliminates bushings to provide lower reciprocating weight
-An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit

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

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

Performance with the Duramax/Allison combination is also improved over previous models, with preliminary testing showing 0-60 mph times of less than 9 seconds and quarter-mile times of less than 16 seconds in 2500HD models. That’s about 0.3-second and 0.5-second quicker, respectively, than previous models.

6. Strengthened Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain

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

A new camshaft profile in the Vortec 6.0L helps the engine produce more torque lower in the rpm band, for improved launch feel and a greater feeling of overall performance at higher altitudes and when towing a trailer.

The 6L90 is enhanced for greater strength, smoothness and quietness via:

-Adding four attachment bosses to the transfer case adapter (4WD models) for increased strength and smoother, quieter performance
-Increasing the cross section size of the transfer case adapter for greater strength
-Adding a new, stronger output shaft
-Adding a new heat shield and vent hose

7. Exhaust brake system

A new feature on Duramax-equipped models is an exhaust brake system. This driver-selectable feature uses the turbine control of the variable geometry turbocharger and the compression of the engine to generate backpressure, slowing the vehicle without applying the brakes. It is a smart system integrated with the cruise control feature and varies the braking to account for the grade and vehicle load.

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

8. Large brakes

Brake feel and performance is greatly improved with the 2011 Silverado HD trucks. The standard four-wheel disc system is completely revamped to deliver smoother, more immediate and confident-feeling performance. Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models.

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

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

9. Refined and capable ride, handling and steering

Longer wheelbases – ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) – and wider front/rear tracks enhance the ride and handling characteristics of the Silverado 2500HD and 3500HD, giving them a greater feeling of smoothness and control.

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

Also enhancing the driving experience is a revised steering system designed to support the trucks’ greater front gross axle weight rating. It includes a new, larger steering gear, power steering pumps and linkages. The pumps (different parts for gas and diesel models) deliver greater pressure for reduced steering effort in low-speed and parking maneuvers; they are also quieter. On some models, the new linkages feature a compliant joint added at the pitman attachment to enhance handling.

10. Comprehensive safety and functional technology

The 2011 Silverado 2500HD and 3500HD models have a comprehensive roster of safety features and functional technologies that include:

-StabiliTrak electronic stability control system on all single-rear-wheel models
-Larger, four-wheel disc brakes with standard four-wheel ABS
-A new high-strength steel tubular frame cross member that enhances safety and improves crashworthiness
-Seat pelvic/thorax and head curtain side air bags available on 2500HD
-Available rear backup camera
-Segment-exclusive OnStar 9.0
-Trailer sway control system on all single-rear-wheel models
-Hill start assist (standard on single-rear-wheel models)

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

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

11. Lives bigger, drives better, works harder

From the available remote starting feature to the unimpeded access offered by the 170-degree-opening rear access doors on extended cab models, the 2011 Silverado HD models live bigger, drive better and work harder. The interiors are refined, with improved quietness and attention to detail, but designed for working. Numerous storage compartments provide covered access for everything from work gloves to laptops.

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

Cold-weather customers will appreciate the Duramax 6.6L’s quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment’s best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm up the interior faster.

And when you’re on the road, the Silverado HDs take you farther without stopping. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of up about 680 miles (1,090 km) with the Duramax 6.6L. That’s the equivalent of a trip from Houston to Oklahoma City and back to Dallas on a single tank.

Finally, all 2011 Silverado 2500HD and 3500HD trucks work under the best warranty coverage in America – five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that Chevrolet backs its trucks confidently.

Love all the thought but into the truck, not a big fan looks wise.

Good thing the GMC Sierra is much better looking, IMO.

Gawd GM you're killin' me. I mean I trust your quality, and your drivetrains, and I want to be a diehard enthusiast, but I'm not. Say I'm not a true 4x4 / truck guy, but I can't justify the gas money... unless I like the way it looks too But when I look at this "new" model, I can see the same basic lines and design schemes that our farm truck has, and it's an '89 Silverado.

Yes people still need work trucks, but (as sad as it may be) a lot of people buy big trucks now for the whole testosterone thing lol... I mean here in Farmland, Indiana most guys rock their Cummins' around town like you'd think they were in a Corvette lol. GM's SUV's aren't too bad, but they still seem kind of all bland IMO. No edginess. They started to do the right thing with the Colorado, but I don't think it ever got enough attention from the people at GM. So it will be a while before I own a GM truck or SUV, assuming that I wait till every year-model is probably 3-5 years old so I can afford it lol.

For now I'll be stickin' with my beloved Jeep brand, and of course the cavy for mpg purposes.

I keep trying to proofread this, btw, but I can't because I'm a little toasted so sorry for any grammatical errors. I'm in college what do you expect haha

I'm impressed.

Didn't mention the 2K price increase over previous duramax engine. They also going to be longer due to the urea injection system was told they added 15 inches of exhaust just to add the burn chamber for the urea. I'm eager to see this urea injection system and if people wil stay on top of the refiling cycles. Still have people coming in saying The exaust filter message is on fix it. There isn't a 2010 duramax by the way if you get a chance to see a 2010 HD truck with the duramax the emission sticker states its a 2009 engine in a 2010 frame(goverment regs and loop holes). I still like that Ford and GM are starting to use the DEF system, dodge on the other hand just cranked exhaust temperatures to meet goverment standards.

Any more pics Mr. Goodwrench?

Update from GM... .

New 2011 Chevrolet Silverado Heavy Duty Trucks Deliver Best-In-Class Diesel Torque And Horsepower

-New 6.6L Duramax turbo diesel rated at 397 hp (296 kW) and 765 lb.-ft. of torque (1,037 Nm)
-Segment-best diesel power complemented by up to 11-percent improved highway fuel economy and up to 63-percent reduced NOx emissions
-Up to 680-mile (1,090 km) driving range with Duramax engine in pickups
-Standard small-block 6.0L gas V-8 delivers 360 hp (268 kW)

Chevrolet’s new 2011 Silverado 2500HD and 3500HD pickups deliver the segment’s best diesel power. Their new, optional 6.6L Duramax turbo-diesel V-8 is rated at 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm – an improvement of 32 horsepower (24 kW) and 105 lb.-ft. of torque (142 Nm) over last year’s engine.
“Segment-leading power is great, but it’s not the only thing that makes the new Duramax a winner,” said Gary Arvan, Duramax chief engineer. “We designed the engine to make that power with less fuel and fewer emissions, while also increasing its durability.”

A slightly different version of the 6.6L Duramax is offered in Silverado HD chassis and box-delete models. It is based on the same improved architecture and includes most of the same features as the pickup version, but is engineered to meet federal certification standards for incomplete vehicles, including the incorporation of a robust EGR system. It is rated at 335 horsepower (249 kW) at 3,100 rpm and 685 lb.-ft. of torque (928 Nm) at 1,600 rpm.

Among the 2011 6.6L Duramax turbo diesel’s new and enhanced features are:

-Main bearing profiles changed to enhance oil film thickness
-Oil pump flow increased for more pressure at low speeds
-A revised turbocharger oil circuit for increased pressure at the turbo and faster oil delivery
-Connecting rod pin ends modified to provide increased piston support
-New, higher-strength piston design
-A new 30,000-psi (2,000 bar) piezo-actuated fuel injection system – capable of operating on ASTM grade B20 biodiesel – ensures more precise fuel delivery, improving emission performance
-An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit (pickup versions only).

The more powerful 6.6L Duramax is also more fuel-efficient – up to 11-percent greater highway fuel economy than the outgoing model – reduces NOx emissions by up to 63 percent and helps enable greater towing ratings. Silverado 3500HD equipped with a fifth wheel hitch can tow up to 20,000 pounds (9,072 kg). The increased fuel efficiency, combined with a new, 36-gallon (136 L) fuel tank, provides up to 680 miles (1,090 km) of highway driving between fill-ups.
With nearly 1.3 million Duramax diesel engines put into operation since its launch in 2000, no other automaker has as much diesel engine development experience for meeting the demands of the heavy-duty truck customer.

Strong small-block 6.0L V-8

The standard engine in Silverado HD trucks is the Vortec 6.0L small-block V-8, which is enhanced for 2011 with greater idle refinement. It is rated at 360 horsepower (268 kW) at 5,400 rpm and 380 lb.-ft. (515 Nm) at 4,200 rpm in Silverado 2500HD and 3500HD pickup models. In chassis cab and box-delete models, as well as pickups with a GVWR greater than 10,000 pounds, it is rated at 322 horsepower (240 kW) at 4,400 rpm and 380 lb.-ft. (515 Nm) at 4,200 rpm.

Approximately 90 percent of the Vortec 6.0L’s peak torque is available by only 2,000 rpm and excellent fuel economy is enabled by the engine’s low-friction OHV configuration and cam phasing. The state-of-the-art small-block architecture of the Vortec 6.0L – known commonly as the “LS” family – delivers great strength, smoothness and durability.
Whether equipped with the 6.6L Duramax or the small-block 6.0L, all 2011 Silverado models work under the best warranty coverage in America – a five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that Chevrolet backs its trucks for everything the road offers.

Update from GM...
Chevrolet Announces Pricing For 2011 Silverado HD

-Segment-leading horsepower and torque with proven Duramax diesel engine / Allison transmission combination at carryover pricing
-2011 Silverado HD hits Chevy dealerships this summer

Chevrolet announced pricing for the 2011 Silverado HD, highlighted by carryover pricing on the improved Duramax diesel engine and Allison transmission. This means best-in-class horsepower and torque at 397 HP and 765 lb-ft of torque, respectively, for the same option price as 2010 models.

“Heavy duty pickup customers are some of the most knowledgeable out there, and we heard them loud and clear. They want maximum power and capability at the best value possible,” said Product Director Maria Rohrer. “We delivered huge increases in power and capability while actually improving our fuel economy with the Duramax diesel engine – all while maintaining current pricing.”

Silverado HD base pricing starts at $27,965, which excludes a $995 destination charge. An upgrade to the proven Duramax diesel engine and Allison transmission combination runs $8,395 – the same amount as in 2010, despite the significant improvements in fuel economy – including a highway cruising range of up to 680 miles; aforementioned increases in performance; and new B20 biodiesel capability.

The 2011 Silverado HD also offers the latest technology in driver confidence and control features such as trailer sway control, smart exhaust braking, hill start assist and more. An all-new chassis, featuring a fully-boxed, high-strength steel frame combines with the aforementioned engine improvements to increase trailering capacity to 20,000 pounds (9,072 kg), and payload capacity to 6,335 pounds (2,873 kg).

The Silverado HD will be offered in work truck, LT and LTZ trim levels, and will begin production in May. Delivery to dealers is expected in early June. All models come with a segment-best five-year/100,000-mile powertrain warranty.

Hopefully the build quality is better. My father and next door neighbor both have 1500's and the doors are terrible... they sound hollow. Also, the interior is pretty shoddy on 'em. I haven't bought a new SUV or Truck due to this. I need something that can pull a boat, yet has a good build.

Maybe they both got lemons? *Shrugs*

Update from GM... .

Silverado HD Bests the Competition with 21,700 Pound Towing and 6,635 Pound Payload Ratings

Through ongoing development and testing, the 2011 Chevrolet Silverado HD capability ratings have been increased to 21,700 pounds of towing, and 6,635 pounds of payload. Based on these ratings, the Silverado HD will offer heavy-duty truck buyers the most power and most capability available in the segment.

According to Rick Spina, GM Full-size Truck global vehicle line executive, the increased ratings are a result of exceeding the original performance targets for the Silverado HD:

“Our focus has consistently been on delivering customers the most capable heavy-duty trucks in the market. The first set of capability tests confirmed that the team had exceeded the payload and towing targets by a significant margin. Ongoing testing demonstrated a clear opportunity to increase the true capabilities of these trucks. Even pulling a combined weight of nearly 15 tons seems easy behind the wheel of a 2011 Silverado HD 3500 with the proven Duramax Diesel.”

To certify increased payload and towing capacities for the 2011 Silverado HD, engineers conducted a battery of tests.

-Based on extensive testing at maximum gross combined weight rating (GCWR) to validate the durability of the powertain, drivetrain, and brake components, the GCWR is increased to 29,200 pounds.
-Based on further testing in varied terrain, grades, and climates while pulling the maximum trailer weight to confirm predictable and stable handling, the maximum 5th-wheel towing capacity was increased to 21,700 pounds, and conventional towing capacity increased to 17,000 pounds.
-After higher-strength steel for cargo box cross sills was specified, the team conducted additional testing hauling maximum payloads to test the stronger cargo box and rear-axle components. As a result, the maximum payload has been increased to 6,635 pounds.

Based on these improved capacities, the 2011 Silverado HD possesses segment-leading capability in horsepower, torque, conventional towing, 5th-wheel towing, and payload.

Starting production next week, it becomes the most capable heavy duty pickup on the market.

“We encourage consumers to test drive the Silverado HD against competitive models,” said Spina. “Based on our test results, we are confident the Silverado HD will prove to be the best choice for real-world towing and hauling needs.”

I used to drive a 2003 F-350 Turbo Diesel when I did commercial roofing, that engine had ballz and so did the 2007 F-250 that the formen drove when he hauled the trailor across country (went from MN to SC and MN to CA) Those engines had a lot of power to them. I drove a 2008 GMC 2500 and the engine had no balls, when you stomped on the gas pedal nothing happened, you weren't even able to feel the turbo kick in.

The only thing that Chevy really beat Ford on (atleast more than 150) was the Max. Conventional towing. Other than that, they barley squeeked by. But then again, I'd rather have an independant (non consumer reports type) study done on all three of these trucks.

Duromax with no balls....don't think so.

GM missed the boat when they didn't make a monster pickup like the ford. Guys pulling equipment around like the extra weight.

If I was running a fleet again, I'd still go GM truck!

I'm sure plow operators miss the old front suspension.
