2001 Chevrolet Silverado Heavy Duty

NEW SILVERADO AND SIERRA HD MODELS POWER THEIR WAY TO TOP OF SEGMENT

2001 Chevrolet Silverado Heavy Duty
Building on the success of the regular duty pickups in 1999, Chevrolet and GMC are out to revolutionize the heavy-duty market in 2001 with the segment's most powerful lineup of all-new three-quarter and one-ton pickups and chassis cabs.

'The superlative power of our new heavy-duty Silverado and Sierra, coupled with their best-in-class capabilities, durability and improved efficiency, nail every customer requirement and then some,' said Tom Stephens, GM Vice President and Group Director of the Pontiac Vehicle Engineering Center. 'They provide customers with nothing less than a new standard for this segment'

COMPREHENSIVE LINEÚP

Chevrolet Silverado and GMC Sierra each offer a wide selection of 32 heavy-duty models, including 2500HD (3/4-ton) and 3500 Series (one-ton) regular cabs, four-door extended cabs, Crew Cabs and chassis cabs.

Four special versions of the heavy-duty pickups, with a reduced gross vehicle weight rating (GVWR), are also available for alternative fuel vehicle customers.

MOST POWERFÚL ENGINE LINEÚP

The segment's most powerful gasoline and diesel engines drive the 2500HD/3500 Series to the head of their class in performance. The new powertrains were all validated for an extended operating life of at least 200,000 miles (322,000 km), without major component failures. They also incorporate new low maintenance features and provide better economy than the powertrains they replace.

DÚRAMAX 6600 V8 TOPS DIESEL CLASS

A totally new Duramax 6600 diesel V8 replaces the previously available 6.5-liter turbo diesel. The Duramax 6600 is a state-of-the-art, 90-degree, direct-injection, overhead valve, four-valve-per cylinder, turbocharged and intercooled V8, developed through a joint venture between (DMAX Ltd.) between GM and Isuzu Motors. It is built at a new plant in Moraine, Ohio.

From virtually any perspective, the optional new Duramax 6600 provides more customer benefits than competing Ford and Dodge diesels.

HIGHLIGHTS INCLÚDE:

• Awesome power. With 300 hp @ 3100 rpm and 520 lb.-ft. (705 Nm) of torque at 1800 rpm, the Duramax 6600 produces 65-70 more horsepower and 20-70 lb.-ft. more torque than the competition's diesels.
• Segment-leading acceleration at any load level. Acceleration tests actually show that the heavier the load it pulls, the more quickly the Duramax 6600 outdistances its competitors.

• Amazingly quiet operation. At cold-idle startup, for example, it produces only 78 decibels of sound ­ about half the noise level of its next quietest competitor, Ford's 7.3-liter diesel.

• Best-in-class power-to-weight ratio. Lean and powerful, the Duramax has a 0.9 power-to-weight ratio compared to the 0.5 ratio of its two heavier and more sluggish competitors.

• Nineteen percent better specific fuel economy than the 6.5-liter Best-in-class durability and reliability. The Duramax 6600 was tested at more than twice the duty cycles and operating time of its predecessor.

• Easy serviceability/reduced maintenance. Shorter and narrower than any of the competitors' diesels, the Duramax 6600 provides easier access to external components and items like the
timing gear train, the oil filter and the fuel filter.

• Like the other new engines, the Duramax has extended, 7,500-mile (12,000-km) oil change intervals under normal operating conditions and five-year, 50,000-mile (80,000-km) engine coolant.

VORTEC 8100 BIG BLOCK V8 TOPS COMPETITORS' V-10S

An equally impressive new, optional Vortec 8100 V8 gas engine replaces the previous Vortec 7400. Built on one of the most celebrated engine foundations in automotive history, GM's Big Block V8, nearly 80 percent of the Vortec 8100's parts are new. It shares its predecessor's valve and bore centers and bore diameter, but features a 9.4mm longer stoke for higher displacement and more power.

With 340 horsepower at 4200 rpm and 455 lb.-ft (617 Nm) of torque at 3200 rpm, the Vortec 8100 actually produces 40-65 more horsepower and 30-45 lb.-ft of torque than Ford and Dodge's V10 engines!

The Vortec 8100 also provides four percent better specific fuel economy than its predecessor, best-in-class gas engine acceleration and major emissions improvements. Operators can run on alternative fuels such as compressed natural gas (CNG) or Liquid Propane Gas (LPG), without requiring special valves and seats. The Vortec 8100 is so tough, it even stands up to severe marine and industrial use! Oil changes are the only scheduled maintenance requirement during the first 100,000 miles (160,000 km) of operation. And even they have been simplified. GM's Oil Life™ monitoring system tells owners when an oil change is required, based on actual usage and need. An oil level sensing system also alerts operators of the need to replenish oil.

The Vortec 6000 V8 replaces the Vortec 5700 to become the most powerful standard engine in its class. With 300 hp @ 4400 rpm and 360 lb.-ft (501 Nm) of torque @ 4000 rpm, produces 40-50 more horsepower and 25-35 more lb.-ft. of torque than the competition's largest gasoline V8s.

New-for-2001 engine design changes include cast aluminum cylinder heads, intake and exhaust ports that provide major gains in volumetric efficiency (better breathing), a high lift cam and a low restriction induction and exhaust system. The Vortec 6000 shares the Vortec 8100's low maintenance features.

All new 2500HD/3500 models have a standard engine hour meter that also allows fleet and commercial operators to calculate more precise servicing schedules for their engines.

INCREASED AVAILABILITY FOR ALTERNATIVE FÚELS

Both the Vortec 6000 and Vortec 8100 are capable of running on either compressed natural gas (CNG) or liquid propane gas (LPG). The Vortec 6000 requires an (RPO KL5) option to run on these fuels. The Vortec 8100 is already gaseous fuel compatible.

Two other options, (RPO KL7) for LPG and (RPO KL8) for CNG, also provide customers with fully converted, dedicated alternative fuel systems installed at time of delivery. The options are available on 2500 Series 2WD/4WD Regular and Extended Cab pickups. A lower 8,500-pound (3,856-kg) GVW rating on these models enables customers to qualify for special federal government credits and monetary incentives and to meet 'clean fleet requirements' in different geographic areas. IMPCO Technologies of Irvine, California, installs the alternative fuel systems. They carry a full 36-month/36,000 (60,000-km) mile warranty. Chevrolet and GMC dealers do the warranty work.

NEW SMOOTH-SHIFTING, HIGH CAPACITY TRANSMISSIONS

The Duramax 6600 and Vortec 8100 mate to new smooth shifting, high capacity transmissions, including a standard ZF S6-650 six-speed manual and optional Allison 1000 five-speed automatic. Both have close-ratio gearing, which provides exceptional launch, hill climbing and towing capability and economy. Their heavy-duty components are stronger than those typically found in one-ton truck transmissions, providing exceptional durability.

The ZF S6-650 six-speed is fully synchronized in all gears for easy shifting. Dual cone synchronizers in second and third gear provide extra capacity. High helix angle gears provide quiet operation. A convenient shift pattern allows the shift lever to be moved forward for reverse and straight back for first, providing easy low speed maneuvering. Second can be used for launching unloaded or lightly loaded trucks. First gear can be used as a 'creeper gear' for extra low-end performance. As part of its low maintenance design, the ZE S6-650 uses synthetic gear oil. This provides 'lubed-for-life' operation and better reliability by eliminating unnecessary external oil-cooling components.

The Allison 1000 is a GM-exclusive. It has full electronic control of shift timing points, five forward speeds, and helical-type planetary gearsets for quiet operation. It also provides two operating modes, normal and Tow/Haul. In the latter, the torque converter clutch engages in second, third, fourth and fifth gears to avoid excessive heat buildup when the truck is heavily loaded.

Among its features, the 1000 Series provides Engine Grade Braking™, which automatically downshifts the transmission on steep grades to help slow the truck and prevent excessive use of the brakes. It
downshifts from fourth to fifth in its normal operating mode. In the Tow/Haul, the transmission will even do multiple downshifts (fifth to fourth, fourth to third) to steadily slow the truck on steep grades. The Tow/Haul mode also provides Shift Stabilization, which reduces 'shift busyness' in mountainous or hilly terrain.

The 1000 Series has easily accessible fluid fill ports on either side of the main case and an external spin-on oil filter. The oil and filter need only be replaced every two years or 50,000 miles (80,000 km) under normal operating conditions. A standard temperature gauge and a temperature monitoring
system alerts the operator to excessive heat levels.

The previously standard (MW3) heavy-duty five-manual and GM's optional 4L80-E four-speed electronically controlled automatic transmission are carried over for the Vortec 6000. The 4L80-E also provides the benefits of Passive Shift Stabilization with its Tow/Haul mode, two year/50,000-mile (80,000-km) oil change intervals and a standard temperature gauge and temperature monitoring system.

TOP HAÚLING, TRAILERING CAPABILITY

With their awesome power, tough new frames, advanced suspensions and higher capacity brakes, the 2500HD/3500 Series provide outstanding payload capacities and unparalleled hauling and trailering capabilities, including:

• The 3/4-ton segment's highest 9,200-pound (4,173 kg) GVWR (400 pounds/181 kgs more than competitors) and payloads of up to 3,964 pounds (1,798 kgs).

• The one-ton pickup segment's highest 11,400-pound (5,171-kg) GVWR (200 pounds/90.7 kg more than Ford and 900 pounds/408 kgs more than Dodge) and payloads of up to 5,753 pounds (2,610 kgs).

• An 11,400-pound (5,171-kg) GVWR for 2WD chassis cabs and 12,000-pound (5,443-kg) GVWR for 4WD chassis cabs (exceeding Ford's gasoline engine) maximum by 200 pounds/90.7 kg and 800 pounds/363 kg, respectively. Chassis cabs provide payloads of up to 6,089 pounds (2,762 kgs).

Both the Vortec 8100 and Duramax 6600 Diesel V8 permit towing trailers weighing up to 12,000 pounds (5,443 kgs); they provide a maximum 22,000-pound (9,979-kg) gross combined weight rating (GCWR). The trucks' best-in-class trailer ratings are only limited by the weight distributing range of the platform hitch itself.

With a fifth wheel or gooseneck hitch (placed about three inches in front of the rear axle), trailering capability increases to an even more astounding 15,800-pound (6,804-kg) maximum. The Vortec 8100 provides its maximum ratings with either a 4.10:1 or 3.73:1 axle ratio; the Duramax 6600 provides them a 3.73 axle ratio.

With a weight-distributing platform hitch and 4.10 axle ratio, the Vortec 6000 V8 permits towing trailers weighting to 10,500 pounds (4,763 kgs) and provides a maximum 16,000-pound (7,257-kg) GCWR.

The heavy-duty pickups are completely trailering ready. A Heavy Duty Trailering package is optional. A Trailering Equipment package provides the weight-distributing hitch platform, eight-wire trailer harness with mounted connector and a jumper harness with a convenient plug-in for connecting the electric trailer brake controller.

New features like larger recovery hooks and a wider choice of outside mirrors than before further enhance towing.

STRONGER FRAMES

A modular, sectional frame with outstanding strength, reduced weight and precise dimensional control provides the ideal platform for their rugged use and smooth ride. The frames, strengthened over their predecessors, permit better suspension tuning for improved ride quality and more precise handling, whether the truck is loaded or unloaded.

Hydroforming technology is used for the front frame rails of all models. On pickups, the mid-rails are roll formed and drawn bent, using high-strength, low-alloy (HSLA) steel to create their extremely strong, stiff 'lipped' C-shape cross section. They have an impressive 261,000 pound-inch resistant bending moment (RBM). The pickups' rear rail is an HSLA stamping, with a deeper, uniform 200mm
C-shaped cross section.

The 3500 Series are the only chassis cabs in their segment to meet all of the National Truck Equipment Association's requirements for quick, cost-efficient mounting of specialized bodies and equipment. They have clear, flat 34-inch (864-mm) wide rails and a larger, standard 50-gallon (189-liter) dual fuel tank system. (Short box pickups provide a 26-gallon/98-liter fuel tank and long box pickups a 34-gallon/129-liter tank.)

IMPROVED BODY STRENGTH

More rigid body structures create a comfortable, quiet, rattle-free driving environment. Bodies have a high 23-hertz rating. Design features such as a 'spider assembly' beneath and welded to the cab floor, a double-boxed rocker section with more depth than before and a laser-welded door ring help create the exceptional stiffness.

ADVANCED SÚSPENSION SYSTEM

A long- and short-arm independent front torsion bar suspension is standard on all models. It provides a smoother ride, greater durability, more on-center feel and better stability than before.

Semi-elliptic multi-leaf rear springs operate in two stages on pickups and in three stages on one-ton chassis cabs, providing a smooth ride, whether the trucks are loaded or unloaded.

The 2WD models' front tracks are 4.2 to 5.3 inches (107 to 135 mms) wider than before and
rear tracks on all models have increased by 0.9 inches to 1.7 inches (22.8 to 43.2 mms) for improved cornering and stability.

IMPROVED BRAKING

A world-class four-wheel disc brake system, featuring GM's powerful Hydro-Boost™ brake apply system and four-wheel ABS, is standard all models. It provides shorter stopping distances, more linear control with less required pedal effort, quieter operation and more than double the brake pad life of previous models.

Audible wear sensors are used on the inboard and outboard disc brake pads of both front and rear systems to provide a better warning of impending pad wear out.

IMPROVED STEERING

An integral recirculating ball power steering system provides optimum efficiency and durability. Among several other changes, the steering gear has been retuned for better handling than before and two-wheel-drive models receive a whole new steering knuckle GM's automatic toe-in process at plants provides a more precise front-end alignment.
NEW WHEELS

Standard 16 x 6.5-inch eight-bolt steel wheels and rim contours provide more room inside the rim for the larger brakes. A new wheel facing increases brake ventilation.

HIGHER CAPACITY TIRES

The 2500HD/3500 Series also have higher E-load range tires than before to help provide for increased load-carrying capability. The 2500HD models feature standard LT245/75R16E radials with either an all-season or on-/off-road design, depending on the model. The 3500 Series have standard LT215/85R16-E highway or on-/off- road radials. A full-size spare is standard.

EXTERIOR DESIGN

The Silverado HD and Sierra HD have never been more distinctive. The Silverado HD has a massive new front-end appearance that includes wider openings and a bolder chrome center bar displaying its giant, gold Chevy bow tie. Its hood is elevated, and its front bumper pads thicker to accommodate a two-inch (51 mm) higher body height (than the regular duty Silverado.) The Sierra HD also has a taller, more confident and capable design. Its signature center port grille has a chromed look; louvers direct 14 percent more air under the hood (than predecessor models) for enhanced engine cooling.

Both models feature integrated wheel flares that add to their strong, aggressive appearance. Big Dooley models feature stylish one-piece composite rear fenders that reduce weight while adding durability. A new headlamp system for the heavy-duty pickups offers an effective illuminating range of 400 feet (122 meters).

Larger 6.5-foot (2.0-meter) and eight-foot (2.4-meter) cargo boxes provide two percent more cargo volume than predecessor models.

LARGER CABS

Regular, four-door, extended and Crew Cab sizes have all been increased over previous designs for significantly more interior room and outstanding passenger seating comfort.

The extended cab provides the industry's largest rear-door openings. The all-new Crew Cab provides even more headroom, leg room and hip room than the segment-leading Extended Cab. Compared to the previous Crew Cab, it also has 1.1 inches (27.9 mm) of additional head room, an extra 1.4 inches (35.6 mm) more front hip room; 0.7 inches (17.8 mm) more rear leg room; 0.2 inches (5.1 mm) more rear shoulder room and 3.6 inches (91.4 mm) more rear hip room.

MORE FLEXIBLE CREW CAB SEATING

Like the regular and extended cab, the Crew Cab offers a front 40/20/40 split bench or individual bucket seats. A choice of seating surfaces includes leather seating, available with the uplevel Silverado LT/LS and Sierra SLT trim offered on extended cab and Crew Cab models.

The Crew Cab's rear seat is a 40/60 split bench with room for three passengers. Outboard passenger head restraints are vertically adjustable and don't have to be removed to fold the backrest down for extra storage room. The seat can be folded to create a large, flat surface that's ideal for carrying luggage, tools or pets. Three child-seat upper-tether anchors on the back of the rear seat improve safety, a segment-exclusive rear fold-down center armrest with two cupholders and a stowage tray enhances comfort.

With bucket seats, the Crew Cab also has a center console with a large, lockable storage volume, two cupholders, extra stowage in the lid and a coin holder. The rear of the console, like that of the extended cab, also has two more cupholders, adjustable air conditioning vents with positive shutfoffs and a small storage bin for rear passengers. Depending on the trim level, either an overhead mini or full feature console also provides additional storage room on all models.

BETTER TEMPERATÚRE CONTROL

The heating, ventilating and air conditioning system operates more quietly, provides best-in-segment cool-down comfort and better heater and defroster performance than before. It also provides segment-exclusive rear-seat heater ducts as standard equipment. A new five-speed rotary fan control and rear-seating A.C. outlets (with the extended console) provide optimum comfort and balanced airflow. Crew Cabs also offer optional (RPO C68) electronic temperature control, which maintains temperature at a precise, specific setting throughout the cab.

MORE SAFETY AND SECÚRITY

The 2500HD/3500 Series add many new safety and security features, headed by the On Star™ system. It is now standard on uplevel Silverado LT and Sierra SLE extended cab and Crew Cab models.

All models have standard dual air bags, with a passenger side deactivation switch on regular and extended cab models to protect small occupants. They also have seat-mounted safety belts on the
outboard seating positions of all front row seats.

The Silverado LS and LT and Sierra SLE and SLT have standard programmable automatic locking and unlocking doors. Crew Cabs add child security rear door locks. Inside rear door handles on extended cab models are deactivated whenever the doors are closed. The Driver Message Center provides up to 18 alerts, regarding potential service or safety-related concerns.
