Chicago 2010: 2011 Chevrolet Silverado Complicated Avocation ups a ante
Identified by its brandnew energy dome hood, a styling reversion, the 2011 ChevroletSilverado HD arrived at the Chicago Automobile Show riding upon an all-new ladder frame, cessation, as well as axles – about the usually carry-over part is a front stabilizer bar link which connects the stabilizer bar to a reduce control arm. Limit towing capacity is up to 20,000 pounds with a DRW Duramax diesel motor fuel and fifth wheel combo (yes, that trumps the Ford F-Series Super Duty F-350 apples to apples). A gasoline-fed SRW 6.0-liter V-8 engine will lift 14,500 pounds with the fifth wheel.
In further to the beefy hood, a front fender has been revised with a larger emblem and a some-more gaping intake – written to urge transmission cooling. Alternative improvements include 17-inch wheels Customary or optional new 18- or 20-inch alloys. The twin rear-wheel tires are still 17-inch, but th ey rightaway house taller aspect comparativemeasure tires. A improvements for 2011 have been all good headlines for complicated duty lorry buyers with a exception of a circle shaft settlement – the eight-lug heart has the slightly different dimensions definition 2007-10 wheels simply won’t fit. See a rest of a details in a press release after a break.

BRING IT ON – 11 WAYS A BRANDNEW 2011 CHEVROLET SILVERADO HEAVY-DUTY TRUCKS INFER THEY’RE READY FOR ANY JOB OR ASPIRANT
CHICAGO – On a new validation expostulate of a new, 2011 Chevrolet Silverado heavy-duty trucks, operative Brent Low 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 overwhelmed the brakes the entire approach.
Deep relied on the Silverado’s new, intelligent empty stop complement to slow a truck/trailer multiple on descents, helping prove a new system is befitting for a many demanding conditions. It was a drive opposite the heart of the Hilly Mountains as well as some of a interstate system’s steepest grades, with altitudes ranging from Denver’s about 5,000 feet (1,525 m) to some-more than 11,100 feet (3,400 m) at the Eisenhower Hovel.
“It takes some courage to leave your foot off the stop, but the Silverado’s Duramax engine and Allison delivery perform a task with smoothness and confidence which really impresses,” said Low. “Improved still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on prolonged descents.”
The exhaust brake system feature is only asingle of a elements that makes a new 2011 Silverado 2500HD and 3500HD models a many able in the industry. They go on sale this summer.
“We sought the submit of our customers during the growth of a 2011 Silverado HD to broach the truck that meets or exceeds their every need,” said Jim Campbell, Chevrolet general manager. “It offers larger strength and capacity – togetherwith class-leading fue l saving, trailering as well as cargo ratings – and has some-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 Taxi with the 6.5-foot cargo box. WT, LT and LTZ trim levels are offered, and renouned facilities such as a EZ Lift tailgate and rearview camera complement lapse. All models bring larger capacity, softened ride and handling and the greater feeling of driver control. Depending upon the model:
* Segment-best fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
* Segment-best required towing genius increases up to 23 percent, with the maximum of 16,000 pounds (7,272 kg)
* Segment-best payload capacity of 6,335 pounds (2,873 kg) on a complete car
* Segment-best Gross Total 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 Spindle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
* Snow plow capacity is rightaway enabled for all 4WD cab configurations
There have been additionally extended powertrains, including the new Duramax 6.6L diesel/Allison 1000 six-speed delivery which offers the exhaust brake complement, brandnew front and rear suspensions, an improved brake complement, hill begin assist, trailer sway control system as well as some-more.
“Along with all their heavy-duty apparatus, these trucks are written to be invogue and refined, inside as well as out,” pronounced Campbell. “You paid tighten attention to all the sum, giving them a particular, muscular appearance on a extraneous and a well-appointed interior with the comfort, convenience and safety facilities business appreciate.”
Outside, the 2011 Silverado 2500HD and 3500HD models are renowned by the energy dome-style hood with the brandnew, louvered design, as good as a brandnew grille as well as full-width chrome steel front fender. THE new lineup of 17-, 18- as well as 20-inch wheel/tire combinations is featured, aswell (20-inch discrim inating forged aluminum wheels are available on 2500HD).
Designers and engineers left almost no bolt unturned during a comprehensive redesign of the trucks. Here are 11 pass elements that demonstrate a 2011 Silverado 2500HD and 3500HD have been ready for any job as well as any aspirant:
1. New frames
In the query to comprehensively redesign the Silverado HD chassis to urge continuance as well as float, while additionally ancillary increased capability, engineers grown 11 all-new, fully boxed frame assemblies. A frames have increased cross sections and use some-more high-strength steel for greater continuance, higher towing genius and softened ride and doing; a front sections are hydroformed.
A bending as well as lucent rigidity of the frames is increasing 92 percent as well as 20 percent, re spectively, with a fully boxed sections enhancing torsional stiffness by a cause of five. Additionally, larger engine as well as transmission mounts, coupled with a 125-percent-stiffer front frame makeup, provide greater quivering control, while hydraulic physique mounts have been incorporated under the taxi territory on extended and crew cab models for the some-more removed feel inside.
Engineers addressed common customer as well as aftermarket uses when designing a brandnew frames, including adding entrance holes to the rear support territory to capacitate simpler designation of fifth-wheel/gooseneck-style hitches. Additionally, the frame-mounted hitch for conventional trailering is stronger, with a box-tube pattern. It supports up to 16,000 pounds (7,257 kg).
2. Brandnew as well as clever independent front cessation
A completely redesigned independent front suspension system offers up to a 25-percent larger front axle weight rating – up to 6,000 pounds (2,721 kg) front sum spindle weight rating (FGAWR) – enabling a snow plow to be used on all 4WD cab configurations with a available sle et plow prep package, whilst also supporting softened float and doing characteristics.
Silverado’s signatur e short-long arm/torsion bar front suspension design is retained, though rightaway features new, forged steel top control arms which are stronger and lighter than their predecessors. A brandnew lower control arms are done of precision-machined expel iron to hoop the larger loads. Five dissimilar torsion bar rates await five dissimilar front gross spindle weight ratings The singular torsion club was previously used for all models). This helps stabilize the range of trim heights of various models underneath load, whilst enhancing appearance, handling, continuance, tire wear and alignment. The trim height is adjusted on any club around a single bolt, simply permitting the tallness to be changed to account for the weight of a snow plow or other accessories.
A Silverado HD front suspension now uses the pair of urethane hop bumpers upon each side, instead of asingle, for improved load government; as well as there’s the new top shock mount connection pattern that’s positively connected to the frame with two fasteners. This design eliminates squeaks and clunks, while supporting aloft load capability and increased durability.
Compared to competitors’ beam-axle front cessation, the Silverado’s eccentric front cessation provides a improved ride, more correct trim height control (with fewer tools and greater coherence to adjust the fixing for weight as well as tire attraction.
3. New asymmetrical leaf-spring back cessation
Co-ordinate with the Silverado HD’s larger strength and capacity is the back suspension designed to await larger loads. It features a new, incomparable asymmetrical leaf-spring design that also contributes to i mproved ride and doing characteristics.
A asymmetrical pattern is derived from unsymmetrical front and rear spring half lengths, that minimize spindle hop as well as raise traction control efficiency. 2500HD models feature the two-stage leaf-spring design, while 3500HD models have the three-stage design. All models feature 3-inch-wide (76 mm) root springs which have been 20-percent wider than prior models.
A incomparable leaf-spring design supports increased rear sum spindle weight ratings across a board. Upon the 2500HD models, the rating is 6,200 pounds (2,818 kg) – up from 6,084 (2,765). On 3500HD models, a rating increases to 7,050 pounds (3,204 kg) upon single-rear-wheel models and 9,375 pounds (4,261 kg) upon dual-rear-wheel models – a latter representing the nearly 14-percent enlarge over a prior 8,200-pound (3,727 kg) rating.
4. Segment-leading towing and payload capability
Stronger frames, cessation systems with greater weight ratings as well as enhanced powertrain systems minister to the Silverado HD’s class-leading towing and payload capacity. The specifications charts included below outline capacities for any model and/or configuration, but here are the pass contribution:
* The limit conventional (ball hitch) towing rating increases to 16,000 pounds (7,257 kg)
* A Silverado 3500HD organisation 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) as well as the 2010 Ford F-350 is rated at the maximum of 18,800 pounds (8,545 kg). It should be noted which while Ford claimed segment-leading trailering and payload during its recent announcement of a 2011 Super Duty models, no towing ratings were released
* The maximum cargo (3500HD) is 6,335 pounds (2,873 kg) – that’s nearly 11 percent greater than a 2010 Ford F-350’s 5,730-pound (2,604 kg) rating as well as about 24 percent so me-more than a 2010 Impel 3500’s 5,130-pound (2,331 kg) ratings. Again, while claiming segment-leading cargo for a 2011 Super Avocation models, Ford did not announce a ratings
5. Brandnew 6.6L Duramax diesel motor fuel as well as Allison 1000 six-speed combination
Assisting a brandnew 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 involuntary delivery powertrain combination. A Duramax 6.6L is some-more absolute as well as durable and a Allison 1000 is stronger as well as helps capacitate brandnew facilities, togetherwith the exhaust stop complement. Together, this improved version of a proven multiple is additionally expected to broach segment-best fuel economy.
A Duramax 6.6L’s new and improved facilities in clude:
* Horsepower and torque approaching to tip previous model Contrast is ongoing – check media.gm.com for updates)
* NOx emissions markeddown during slightest 63 percent over 2010 models
* Quieter operation
* High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel potency, softened performance as well as reduced emissions
* Empty stop complement that enables controlled vehicle slowdown on downhill grades without actuating a brakes
* Selective catalytic reduction after-treatment system using diesel motor fuel exhaust liquid (DEF) injection to yield a most appropriate overall diesel characteristics as well as opening – with a operation of about 5,000 miles (8,000 km) between DEF refills
* Explosion and after-treatment have been optimized to yield about 700 miles (1,125 km) in between diesel motor fuel particulate filter regenerations – a 75-percent alleviation over the prior complement and significant writer to improved fuel eff iciency, as a regeneration process requires additional fuel
* B20 biodiesel capacity for an alternative fueling option
* Inner revisions that urge durability
With scarcely 1.3 million Duramax 6.6L engines produced given 2000, they have proven exceptionally durable as well as dependable. The inner elements that helped setup its reputation are extended for 2011, including:
* Categorical orientation’ profiles changed to enhance oil movie density
* Oil siphon flow increased for increased vigour at low speeds
* A turbocharger’s oil circuit is altered to provide increasing pressure at the turbo as well as faster oil smoothness
* A connecting rods’ pin ends have been mutated to provide increasing piston await
* Brandnew, higher-strength piston pattern which eliminates bushings to provide lower reciprocating weight
* An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit
A enhanced Allison 1000 for 2011 is strengthened to handle a higher torque capacity of the brandnew 6.6L Duramax engine, whilst also helping improve fuel economy as well as yield seamless benefit with the new empty stop system. Greater potency is delivered through markeddown “spin loss” – definition, a delivery channels some-more of the engine’s energy to a axles, allowing it to do some-more with reduction fuel.
The Allison 1000 additionally features motorist change control with daub up/tap down changeable as well as the patented elevated resting mode cab warm-up feature. Additionally, the tow/haul mode reduces shift cycling for improved control and improved cooling when towing or hauling heavy loads. A six-speed pattern retains the two overdrive gears for optimal efficiency.
Performance with the Duramax/Allison multiple is also improved over prior models, with preliminary testing display 0-60 mph times of less than 9 seconds as well as quarter-mile times of less than 16 seconds in 2500HD models. That’s about 0.3-second as well as 0.5-second quicker, respectively, than prior models.
6. Strengthened Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain
The princely Vortec 6.0L gas V-8 with variable valve timing earnings to the new heavy-duty trucks, along with the strengthened version of the Hydra-Matic 6L90 six-speed automatic transmission. This multiple delivers excellent performance as well as potency, with the larger emphasis on low-rpm power.
THE brandnew camshaft profile in the Vortec 6.0L helps a engine furnish some-more torque reduce in the rpm band, for improved launch feel and the greater feeling of overall performance during aloft altitudes and when towing a trailer.
The 6L90 is extended for greater strength, fibre and quietness around:
* Adding four attachment bosses to the transfer box adapter (4WD models) for increasing strength and smoother, quieter opening
* Augmenting a cranky section distance of a transfer box adapter for greater strength
* Adding the brandnew, stronger outlay shaft
* Adding the brandnew heat defense and opening hose
7. Empty stop system
THE new underline upon Duramax-equipped models is an exhaust brake system. This driver-selectable underline uses the turbine control of the variable geometry turbocharger and the compression of a engine to generate backpressure, negligence the vehicle without requesting the brakes. It is a intelligent system integrated with the cruise control underline as w ell as varies a braking to account for a grade and vehicle load.
A empty brake complement allows for probably effortless driving and towing, with seamless as well as still operation. It also helps prolong brake holdup and prevents overheating the brakes on long, downhill grades.
8. Large brakes
Brake feel as well as performance is severely improved with the 2011 Silverado HD trucks. The customary four-wheel disc system is completely revamped to broach smoother, more immediate and confident-feeling opening. Four-wheel, four-channel ABS is standard upon all single-rear-wheel models and a three-channel complement is standard on dual-rear-wheel models.
A front as well as back rotors have been larger in diameter – 14 inches (355 mm) – and breadth upon all models to support their increased genius, weight ratings as well as trailering ratings, while the calipers have been stiffer as well as stronger. A hydroboost brake upholder calibration is revised for reduce d pedal bid as well as a travel of the pedal is also revised for a more gentle, confident feel.
Incomparable circle hub as well as bearing assemblies complement the new brake complement and the rear r otors insert to the wheel hubs for easier servicing.
9. Refined and capable float, handling as well as steering
Longer wheelbases – ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) – and wider front/rear marks enhance the float and handling characteristics of a Silverado 2500HD as well as 3500HD, giving them the greater feeling of smoothness and control.
The longer wheelbases and wider tracks have been complemented by a brandnew, stiffer frames, new jounce bumpers, shock mounts and hydraulic physique mounts to yield the plain, well-spoken and isolated pushing knowledge. New sh ocks were specifically valved to support a new trucks’ weight ratings, while balancing glorious ride characteristics.
Also enhancing the driving knowledge is a revised steering complement designed to support a trucks’ greater front sum spindle weight rating. It includes a new, incomparable steering gear, energy steering pumps as well as linkages. The pumps Dissimilar parts for gas as well as diesel models) deliver larger vigour for reduced steering bid in low-speed and parking maneuvers; they have been also quieter. On some models, a new linkages feature the agreeable corner added at the pitman attachment to enhance handling.
10. Extensive safety and functional record
The 2011 Silverado 2500HD and 3500HD models have the extensive register of reserve facilities as well as functional technologies that include:
* StabiliTrak electronic fortitude control system on all single-rear-wheel models

* Available rear backup camera
* Segment-exclusive OnStar 9.0
* Trailer sway control system on all single-rear-wheel models
* Hill start assist (standard upon single-rear-wheel models)
Trailer sway control system provides an combined measure of confidence when towing a trailer. A complement senses conditions of trailer lean and intervenes with braking and/or reduced engine energy to bring the trailer under control and keep it on the intended path. A complement will make use of electric trailer brakes when the trailer is plugged into the standard wiring strap of the truck as well as its opening requires no input from a driver.
A hill begin assist complement is automatically engaged when sensors acknowledge the car is on class of about 5 percent or greater. It binds a brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback – it is quite effective when towing, giving the motorist time to switch from the brake pedal to the gas pedal but rolling.
11. Lives bigger, drives better, works harder
From the accessible remote starting feature to the unimpeded access offered by a 170-degree-opening rear entrance doors upon lengthened cab models, the 2011 Silverado HD models live bigger, expostulate improved and work harder. The interiors are refined, with improved serenity and courtesy to detail, but designed for working. Numerous storage compartments yield lonesome access for everything from work gloves to laptops.
Intruth, for many owners the Silverado HDs are mobile workspaces, charity mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Airwave and the navigat ion complement. Mixed assign points cap acitate mixed electronic inclination to work concurrently; and when versed with the accessible navigation complement, XM NavTraffic offers real-time updates of traffic conditions (in selected areas) that can assistance plan the most effective track to the pursuit site.
Cold-weather business will conclude the Duramax 6.6L’s discerning, reliable start-up, with the starting time on standard with gas engines. The heat block cycle time is the segment’s most appropriate in all temperatures, rece iving no some-more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up underline which allows the engine to idle faster in low temperatures to comfortable up the interior faster.
And when you’re upon a highway, the Silverado HDs take you over without stopping. THE new, 36-gallon (136 L) fuel tank is customary on all models and, with the improved fuel efficiency of a powertrains, enables a cruising operation of up about 680 miles (1,090 km) with a Duramax 6.6L. That’s the homogeneous of the outing from H ouston to Oklahoma Cit y and back to Dallas on a single tank.
Eventually, all 2011 Silverado 2500HD as well as 3500HD trucks work underneath a best guaranty coverage in America – five-year/100,000-mile limited powertrain warranty, and roadside benefit, pleasantness transportation as well as alternative facilities that provide assurance which Chevrolet backs its trucks confidently.
