Validation is to drive a new 2011 Chevrolet Silverado HD trucks, engineer Brent Deep towed 20 000 pounds (9,072 kg) trailer 245 miles (400 km) along the I-70 between Denver and Grand Junction, Colorado - and he just touched the brakes the whole way.
Deep is based on a new Chevrolet Silverado, intelligent exhaust brake system slows the combination of car and trailer bills, helping to test the new system is suitable for harsh conditions. It 'been a disc in the heart of the Rocky Mountains and some inter-state system of the steepest grades with heights from Denver about 5000 feet (1525 meters) above 11,100 feet (3400 m) is the Eisenhower Tunnel.
"It takes courage to let your foot off the brake, but the engine of the Chevrolet Silverado Duramax Allison Transmission and execute the task with the sweetness and confidence that impressed the most," said Deep. "Better yet, the system exhaust brake can help extend the life of brake pads and help prevent overheating of the brakes on long descents. "
The braking function exhaust system is one element that makes the new 2011 Chevrolet Silverado 2500HD and 3500HD, the brightest in the industry. They will go on sale this summer.
"We were looking for input during the development of our 2011 Chevrolet Silverado HD for a car that meets or exceeds their needs," said Jim Campbell, executive director of Chevrolet. "It provides more power and abilities - including the fuel economy leader in its class, trailering and payload ratings - and more power, accelerates faster and has lower emissions This sounds like the very definition makes no compromises .."
The Chevrolet Silverado HD heavy lineup is broader than ever, with 11 2500HD and 3500HD eight wheels and two rear one - including a new 3500HD Crew Cab with a loan of 6.5 meters. WT, LT and LTZ are available, and popular features such as EZ Lift tailgate and return system rear view camera. All models provide greater capacity, improved ride and handling and a greater sense of control of the driver. According to the model:
Segment-best towing capacity of the fifth wheel of 20,000 pounds (9072 kg)
Segment-best towing capacity increases to conventional 23 percent, with a maximum of 16,000 pounds (7272 kg)
better payload capacity of the segment £ 6,335 (2,873 kg) of a complete vehicle
Segment-best gross combined weight rating is £ 27 500 (12500 kg)
Ratings of gross vehicle weight increases up to 17 percent of 13,000 pounds (5,909 kilograms)
Front axle weight rating increased by nearly 25 percent to 6,000 lbs (2721 kg)
Snowplow functionality is now available in all cab configurations 4WD
It 'also need to improve power supplies, such as the new 6.6L Duramax Diesel / Allison 1000 six-speed automatic transmission that offers the exhaust system of brakes, new front and rear suspension, improved braking system, Hill Start Assist and Trailer Sway control and more.
"With all their heavy equipment, these trucks are designed to be elegant and refined, both inside and outside," said Campbell. "We paid special attention to every detail, giving a distinctive appearance, muscular exterior and interior are equipped with comfort, convenience and safety of our customers appreciate."
Outside, 2011 2500HD Silverado 3500HD models differ, and the power dome hood with a new style and new design cues and a chrome grille, full width steel front bumper. The new line-up 17 -, 18 - 20-inch wheels and combination / tire is also present (circles polished 20-inch forged aluminum wheels are available 2500HD).
Designers and engineers left almost no chance to bolt for the review of the trucks. Here are 11 key elements are the 2011 Chevrolet Silverado 2500HD and 3500HD is ready for any job and any competitor:
A new framework
In the search for the complete reconstruction of the Chevrolet Silverado HD chassis to enhance durability and the horse, while supporting increased capacity, engineers have developed 11 all-new, fully boxed frame assemblies. Administrators have increased the sections and a more high-strength steel for durability, greater towing capacity and improved ride and handling, the front sections are hydroformed.
Bending and stiffness of frames is radiating up 92 percent and 20 percent, respectively, fully boxed sections increase torsional rigidity by a factor of five. In addition, major engine and transmission media, combined with a 125-percent-front structure stiffer frame provides greater vibration, while the body of hydraulic engine mounts are formed in the section on Extended Cab models cabin crew for a more isolated feel inside.
Engineers sent to customers and end uses of the secondary market in the design of new executives, including the addition of access holes to the rear frame section to allow easy installation of hooks fifth-wheel/gooseneck- style. Moreover, the classical frame-mounted trailer hitch is stronger, with a tube design of the box. Supports up to 16,000 pounds (7257 kilograms).
Strong new independent front suspension
A redesigned independent front suspension provides a weight division for more than 25 percent per axle - up to 6,000 pounds (2,721 kilograms) front axle weight rating Gross Vehicle (FGAWR) - which allows hunters to use in snow all Cab 4WD configurations with snow plow preparation package available, while also supporting improved ride and handling.
Chevrolet Silverado signature of the short-long arm / suspension design of front torsion bar remains, but now has new, forged steel upper control arms that are stronger and lighter than its predecessor. New lower control arms in precision machined cast iron handle large loads. Five different torsion bar rates to support five different front Gross axle weight rating (one of the torsion bar has been previously used for all models). This will help to stabilize the different cutting heights of the various models under load and at the same time improve the appearance, handling, durability, tire wear and alignment. Cutting height is adjustable through a column of the bolt, can be easily modified when the height of the weight of the snow plow or other accessories.
The front suspension now uses a couple Chevrolet Silverado HD polyurethane cap on each side, instead of one, to manage the occupation has improved, and there is a newly designed upper shock mount bracket is positively related to the framework with two fasteners. This design eliminates the squeaks and clunks, while supporting the greater load capacity and longer life.
Compared to the beam axle front suspension its competitors', Silverado is equipped with independent front suspension provides better ride, the more precise cutting height adjustment (fewer parts), and greater flexibility to change the alignment of the weight and the sensitivity of the tire.
New rear suspension asymmetric leaf spring
force proportional to the Chevrolet Silverado HD and higher performance is the rear suspension is designed to support large loads. It includes a new, larger, asymmetric leaf spring design will also support improved ride and functionality.
The asymmetrical design is derived from the front and rear spring half unequal lengths that minimize the axle hop and improve the efficiency of traction. 2500HD models of two-stage leaf spring design, even if the 3500HD models have a three-tier design. All models have a 3-inch-wide (76 mm), leaf springs, which are 20 percent larger than previous models.
largest leaf spring design supports increased rear gross axle weight ratings across the board. The models are 2500HD rating is 6200 pounds (2,818 kg) - up to 6084 (2765). 3500HD models is an assessment rises £ 7,050 (3204 kg), one of the models of rear wheels and 9375 lbs (4261 kg), two models of the rear wheel - the latter representing about 14 per cent increase over the previous 8200 - pounds ( 3,727 kg) rating.
Segment leader towing and payload capacity
Stronger frames, suspension systems with higher scores weight and transmission systems contribute to increased class tension, the Chevy Silverado HD and payload capacity. The graphs show the specifications of each model includes the construction and / or configuration, but here the main facts:
The classical maximum (wheel), towing rating rises to 16,000 pounds (7257 kg)
Silverado 3500HD crew cab of a frame / time can tow up to 20,000 pounds (9.091 kilograms) with a fifth wheel. The Ram 2010 3500 has a maximum output of 17.600 pounds (8.000 kg) and 2010 Ford F-350 is rated at up to 18.800 pounds (8.545 kilograms). It should be noted that while Ford's Leading says towing and payload during its recent announcement of 2011 Super Duty models, no tow ratings have been issued
Maximum payload (3500HD) is 6335 pounds (2,873 kg) - which is almost 11 percent higher than the 2010 Ford F-350 to 5730 pounds (2604 kg) rating, and about 24 percent more than the 2010 Ram 3500 to 5130 pounds (2,331 kg) of the estimates. Re-support segment-leading models in the payload 2011 Super Duty, Ford has not announced votes
