New for 2013 is a bi-fuel version of the 6.0L engine – known by its LC8 engine code – which features special hardened valves and valve seats that enable it to run on compressed natural gas (CNG) or gasoline.

2013 Silverado/Sierra HD - TheDieselPage.com

The Duramax 6.6L turbo-diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 2500HD and 3500HD models. Highlights of the Duramax diesel include:

  • 397 horsepower (296 kW) at 3,000 rpm
  • 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm
  • 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.

The Allison 1000 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.

Silverado HD chassis and suspension

All Silverado HD models feature fully boxed frame assemblies – 18 different assemblies that accommodate all of the range’s configurations. The front sections are hydroformed.

Additional chassis and suspension features include:

  • Front gross axle weight rating up to 5,600 pounds (2,540 kg), enabling a snow plow to be used on all 4WD cab configurations with the available snow plow prep package
  • Short-long arm/torsion bar front suspension features forged steel upper control arms and precision-machined cast iron lower control arms
  • Four different torsion bar rates support four different front gross axle weight ratings to help 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
  • An upper shock mount attachment design that’s positively connected to the frame with two fasteners, eliminating squeaks and clunks, while supporting higher load capability and increased durability
  • Asymmetrical leaf-spring design that minimizes axle hop and enhances traction control efficiency
  • Two-stage leaf-spring design on 2500HD models and three-stage design on 3500HD model. All models feature 3-inch-wide (76 mm) leaf springs
  • Z71 Off Road suspension is available on LT and LTZ models and includes 35mm deflective disk twin-tube shock absorbers, off-road jounce bumpers, 33mm front stabilizer bar and a skid plate package
  • Four-wheel disc brakes with hydroboost are standard on all models
  • 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 frame-mounted hitch for conventional trailering has a box-tube design and supports up to 18,000 pounds (8,164 kg).

Silverado HD safety and crash-avoidance features

Silverado has a strong body structure to absorb crash energy and provide a protective “safety cage” around occupants. Head curtain side air bags with rollover protection and seat-mounted side-impact air bags for driver and right-front passenger are available. The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment, while the seat-mounted air bags provide thorax and pelvic protection.

Additional safety features include:

  • StabiliTrak electronic stability control system is standard on all single-rear-wheel models
  • Large, four-wheel disc brakes with four-wheel ABS are standard on all models
  • High-strength steel tubular frame cross member that enhances safety and improves crashworthiness
  • Available rear vision camera
  • Trailer sway control system on all single-rear-wheel models
  • Hill start assist is standard on single-rear-wheel models.

The 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.
