Chevrolet Silverado 2500HD
2016 CHEVROLET SILVERADO HD ADDS TECHNOLOGIES THAT ENHANCE
CONTROL AND CONNECTIVITY
Chevrolet Silverado HD trucks are engineered to make the toughest jobs easier, and new technologies for 2016 complement features such as integrated cruise control, powertrain grade braking and diesel exhaust braking to enhance control.
New Digital Steering Assist power steering on some double cab and crew cab models helps make hauling and trailering easier and more confident, with electronic controls that enhance road holding and stability on the highway – particularly on crowned roads – regardless of whether the truck is loaded. It also offers greater responsiveness and an improved steering feel. (Not available on Work Truck models or regular cab.)
There’s also a new Gooseneck/5th Wheel Trailering Prep Package, with a spray-in bedliner, that makes Silverado HD models ready to tow larger trailers right from the factory. It’s available in the first quarter of 2016 for gas and diesel models, and features a frame-mounted hitch platform and tray that accommodates a gooseneck ball hitch or fifth wheel hitch mounting brackets, as well as a cargo bed-mounted trailer harness. A new Gooseneck Completion Kit will also be available from Chevrolet dealers, featuring a 2-5/16-inch ball hitch and two chain tie-downs.
Silverado HD’s MyLink systems are enhanced for 2016, offering greater connectivity choices. They include a new HD radio with a 7-inch-diagonal capacitive touchscreen with performance improvements such as a faster processer for better performance. The available 8-inch system features similar performance improvements and, on High Country models, Apple CarPlay and Android Auto capability.
Additional new features for 2016 include available wireless phone charging, an available remote locking tailgate and three exterior colors: Siren Red Tintcoat (double cab only), Red Hot and Butte Red Metallic (crew cab only).
Also, the 2016 Silverado HDs’ trailering ratings are aligned with SAE J2807 standards, with maximum available capacities including:
- Maximum 2500HD conventional trailering rating of 14,500 pounds (6,577 kg)
- Maximum 2500HD fifth-wheel or gooseneck trailering rating of 18,000 pounds (8,165 kg)
- Maximum 3500HD single-rear-wheel conventional trailering rating of 15,000 pounds (6,804 kg)
- Maximum 3500HD single-rear-wheel fifth-wheel or gooseneck trailering rating of 17,500 pounds (7,938 kg)
- Maximum 3500HD dual-rear-wheel conventional trailering rating of 20,000 pounds (9,072 kg)
- Maximum 3500HD dual-rear-wheel fifth-wheel or gooseneck trailering rating of 23,200 pounds (10,523 kg).
Those maximum ratings are achieved with the available Duramax 6.6L turbo-diesel and Allison 1000 six-speed transmission, a proven powertrain combination with more than 1.5 million sold.
What hasn’t changed for the new model year are the core elements that support the Silverado HD’s capability with durability. It led its segment in the 2015 J.D. Power Vehicle Dependability Study.

Digital Steering Assist details
Silverado HD’s new Digital Steering Assist system continuously adjusts the amount of hydraulic assist provided to the driver while he or she is steering. It’s similar in concept to electric power steering, where a continuous and varied amount of steering motor torque is used to assist the driver, but Digital Steering Assist uses hydraulics is the primary power source.
Compared to a conventional passive hydraulic system, Digital Steering Assist reduces the amount of work and attention the driver exerts to steer and control the truck. As a result, the truck feels more controlled, with excellent stability at higher speeds and on surfaces such as crowned roads. Additional features and benefits include:
- Speed-variable assist – with lighter turning effort at lower speeds, for easier maneuverability in parking lots, and heavier effort at higher speeds to enhance directional control
- Returnability assist – improves the steering wheel return to center after low-speed parking maneuvers
- Pull compensation – recognizes when a hydraulic pressure offset is required while driving on a sloped road, reducing the driver’s need for steering input. The truck drives straighter and the driver is less fatigued
- Improve Tow/Haul mode efforts – similar to speed-variable assist, when the vehicle is in Tow/Haul mode, less effort is required for parking, making it easier to maneuver a trailer, and a heavier effort at higher speeds helps provide a greater feeling of control and stability.
High Country details
With its quiet, well-appointed interior and advanced technologies that bring extra confidence to the most challenging towing situations, the 2016 Silverado High Country HD offers a unique blend of premium capability.

Silverado HD interior details
Silverado HDs are designed to make work easier, and their interiors are roomy, quiet and functional, making them intuitive extensions of owners’ workplaces – or for many owners, their primary office.
A strong cab structure is their foundation for refinement. Nearly two-thirds of the cab is made of high-strength steel, while shear-style body mounts are used to tune out both up-and-down and side-to-side movement for a quiet, comfortable ride. Double and crew cab models have a set of hydraulic body mounts to further isolate the cabs.
The instrument panel has an intuitive six-gauge cluster. Standard models include a 3.5-inch driver information center display in the middle of the instrument cluster, with a 4.2-inch color driver information center display, for vehicle and infotainment data, standard on LT, LTZ and High Country. Ambient lighting highlights all functional areas, such as the “4x4” and headlamp switches, as well as the radio, for easier viewing at night.
All models have extensive interior storage, tailored to the way customers use their trucks. The center console – available on vehicles with front bucket seats – offers nearly one cubic foot (24.5 liters) of combined storage space, with the depth and width to conceal a laptop computer. Additionally, the locking console accommodates hanging files for owners who use their truck as a rolling office, as well as controls for overhead ambient lighting, map pockets along the side, movable cup holders and reconfigurable compartments. It also includes USB ports, two 12-volt power points, a 110-volt outlet and a cord management system, allowing owners to leave their phone charger plugged in for quicker access when it’s needed, but remains concealed and without a dangling cord when it’s not. Plus, there’s a location on the console designed specifically for cell phone storage.
The fold-down center armrest on standard models and other models equipped with the 40/20/40-split bench seat offers covered storage and connectivity, with USB ports and two 12-volt power points.
New wireless phone charging allows compatible phones to be charged without having to connect or disconnect wires or cables. It is available on LT and LTZ double cab and crew cab models with standard bucket seats; and it is standard on High Country.

Connectivity includes MyLink with new phone integration technology, OnStar 4G LTE
Upgrades and enhancements for 2016 include an all-new radio with a 7-inch-diagonal color touchscreen that’s available on the base-model 1SA trim and an 8-inch system offered on higher trim levels and equipment packages.
Both radios offer improved system speed and performance, faster, more accurate map loading, faster service reprogramming and redesigned navigation interfaces, including a quick list of recently browsed points of interest, point of interest country grouping, last destination screen and visual landmark indication with map guidance (on navigation radios only). The 8-inch radio offers enhanced voice command execution, while the new 7-inch radio uses pass-through voice recognition synched with the user’s phone.
An HD radio is also available with the 8-inch system, with or without navigation. On High Country models, it offers Apple CarPlay and Android Auto capability, which provides simple and smart use of smartphones in the vehicle, integrating certain phone functions onto MyLink’s color touchscreen and allowing users to call up music, navigation apps and more via compatible phones.
Complementing MyLink to enhance Silverado’s connectivity is OnStar 4G LTE with a Wi-Fi hotspot. It provides a mobile hub for drivers and passengers to stay connected. The hotspot supports up to seven mobile devices and is on whenever the vehicle is on. It comes with a three-month/three-gigabyte data trial. It is available on the 1SA and standard on SLE, SLT and Denali models.
At the time of purchase, six months of an OnStar Guidance plan includes all of OnStar’s advisor-based safety and security features, including Automatic Crash Response and Stolen Vehicle Assistance, as well as turn-by-turn navigation.

It also includes OnStar Vehicle Diagnostics, which runs monthly checks of a vehicle’s engine, transmission, anti-lock brakes and more, and Dealer Maintenance Notification, which sends a diagnostic report directly to a preferred dealer to simplify service scheduling.
Proven Duramax turbo-diesel
The Duramax 6.6L turbo-diesel is available across the lineup and has proven itself with a strong record of performance, capability and durability. It led the industry with first-in-class common-rail fuel injection and aluminum heads with a six-bolts-per-cylinder design.
It is rated at 397 horsepower (296 kW) at 3,000 rpm and 765 lb-ft of torque (1,037 Nm) at 1,600 rpm, contributing to their tremendous capability – including a maximum towing rating of 23,200 pounds on Silverado 3500HD. Horsepower is reduced slightly for some commercial chassis cab models.
Architectural features include a rigid cast-iron cylinder block with induction-hardened cylinder bores; four-bolt, cross-drilled main bearing caps; forged steel, nitride-hardened crankshaft; aluminum pistons with jet-spray oil cooling; aluminum cylinder heads with four valves per cylinder; water-cooled turbocharger; integrated oil cooler and a charge-cooled turbocharging system.
The Duramax’s variable vane geometry turbocharger makes downhill towing less stressful, with an integrated exhaust brake system. Matched with the Allison 1000 transmission, it creates added backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life.
The Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas engine-like start performance in less than three seconds in temperatures as low as -20 degrees F (-29 C), without a block heater.
Advanced emission control technology makes the Duramax one of the cleanest diesels in the segment. NOx emissions are controlled via a Selective Catalyst Reduction aftertreatment system that uses urea-based Diesel (Emission) Exhaust Fluid (DEF), which is housed in a 5.3-gallon (20 L) tank and needs to be replenished about every 5,000 miles (8,000 km). Electrically heated lines feed the DEF to the emission system to ensure adequate delivery in cold weather.
The system also incorporates GM’s second-generation diesel particulate filter system. Unlike most of the competition, the Duramax regenerates its diesel particulate filter using a downstream injection of diesel fuel directly into the exhaust stream and can travel up to 700 miles (1,125 km) between regenerations. The use of downstream injection helps improve engine life by eliminating concerns surrounding the possibility of diesel fuel contaminating engine oil, which can happen when fuel used for regeneration is introduced directly into the cylinder.
Allison 1000 transmission
The Allison 1000 backs the Duramax engine with features that support its tremendous torque with driver-control features that make hauling and towing easier – including the smart exhaust brake system. It features a class-first range selection function, which allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.
The Allison 1000’s six-speed configuration also contributes to greater efficiency, with lower engine speed on the highway. Both the fifth and sixth gears are overdrives (turning slower than engine speed), with a sixth-gear ratio of 0.62:1. A lower cruising rpm also contributes to a quieter interior on the highway.
Additional features include:
- Power take off – It offers 250 lb-ft of torque for excellent performance in PTO applications, such as snowplows. There are two locations (right- and left-hand sides of the transmission) for PTO accessories – such as hydraulic pumps – to be attached on the transmission
- Driver Shift Control – This feature allows the driver to manually select and hold a gear to satisfy a variety of driving scenarios. The easy tap-up/tap-down shift control holds the desired gear, but also protects the engine by inhibiting downshifts when the engine speed is above allowable rpm limits.
- Tow/haul mode – The driver-selectable tow/haul mode provides greater driver control and trailering performance in certain conditions, such as steep grades. When engaged, shift schedules are optimized so that the system locks the torque converter earlier to minimize heat gain and to take greater advantage of engine braking when vehicle is traveling downhill.
- Cab warm-up (elevated idle) – In certain low-temperature circumstances, the engine speed is raised and the transmission increases the load on the engine, allowing the engine to produce heat quicker and warm up the truck’s interior faster. The idle speed varies with the engine coolant temperature and the normal idle resumes when it reaches 154 degrees F (68 C). The feature is also enabled when the engine is started via remote starting.
- Easy maintenance – The Allison 1000 has an easily removable, spin-on filter with a long, 60,000-mile change interval. Another internal filter is rated for the life of the transmission. Some competitors’ transmissions offer longer filter change intervals, but require more intensive, time-consuming change procedures that include removing the oil pan.
Smart exhaust brake system
The highly integrated, driver-selectable exhaust brake system uses the compression power of the Duramax engine to improve vehicle control and reduce brake pad wear. When the exhaust brake is engaged in cruise mode, exhaust cruise grade braking will help the cruise control system maintain the desired vehicle speed when travelling downhill, keeping the driver from having to apply the brakes and exit cruise control to maintain speed.
When the exhaust brake is engaged in non-cruise mode, the transmission and the exhaust brake deliver the correct amount of braking to assist in vehicle control, regardless of vehicle load. The system provides more engine braking with this feature for a heavier vehicle, for example.
Exhaust grade braking is one of the best examples of the Duramax engine and Allison transmission working as a seamless powertrain unit. It is a smart system that varies the amount of brakes needed for the vehicle, load and grade. The engagement of the system is smooth and quiet, while its performance enhances the driver’s feeling of control.
Standard V-8 power
The standard engine in all 2500HD and 3500HD models is the proven 6.0L FlexFuel V-8, which can run on gas, E85 or a mixture of both. It’s rated at 360 horsepower (268 kW) and 380 lb.-ft. of torque (515 Nm) on gas. It is also offered in a bi-fuel version and is rated at 301 horsepower (225 kW) and 333 lb.-ft. (452 Nm) on CNG.
The 6.0L is part of the legendary small block engine family, which was introduced in 1955. All iterations share basic architectural cues, including 4.400-inch cylinder bore centers and cam-in-block valve actuation. It is a simpler, lighter and more-compact design than many overhead-cam engines, with intrinsic attributes well-suited to the performance heavy-duty truck customers demand – particularly torque that’s developed early and maintained over a broad rpm range.
In fact, approximately 90 percent of peak torque available at only 2,000 rpm, for confidence and ease of operation with a full load or trailer, particularly on steep grades. Additional engine highlights include:
- Deep-skirt iron cylinder block with cross-bolted main caps for strength, durability and refinement
- High-flow aluminum cylinder heads that help produce more power and sustain longer across the rpm range
- Polymer-coated pistons with full-floating wrist pins that offer lower friction, for greater performance and efficiency
- Steel camshaft for long-term performance and durability
- Steel roller rockers add stiffness, allowing greater engine speed with less vibration
- Hydraulic roller lifters reduce friction for greater efficiency and wear resistance
- Steel camshaft for long-term performance and durability
- Regulated voltage control that enhances efficiency by reducing the draw on the alternator
- Coil-near-plug ignition features an individual coil for each spark plug to deliver maximum voltage and consistent spark density, with no variation between cylinders.
Heavy-duty foundation and vehicle control technologies
All Silverado HD models feature fully boxed frame assemblies – 18 different assemblies that accommodate more than 150 possible vehicle configurations across the lineup.
A short-long arm/torsion bar front suspension features forged steel upper control arms and precision-machined cast iron lower control arms. Five different torsion bar rates support five different front gross axle weight ratings to help stabilize the range of trim heights of various models under load – including snow plows – while enhancing appearance, handling, durability, tire wear and alignment.
At the rear, an asymmetrical leaf-spring design minimizes axle hop and enhances traction control efficiency. A two-stage leaf-spring design is used on 2500HD models and three-stage design is employed on 3500HD model.
Silverado HD’s advanced vehicle control technologies are designed to make tough jobs easier and more comfortable, while also contributing to a safe driving experience, particularly when hauling cargo or towing a trailer.
StabiliTrak electronic stability control is standard on all single-rear-wheel models and 3500HD dual-rear-wheel models. It incorporates trailer sway control and hill start assist. Additionally, available cruise control, auto grade braking, and diesel exhaust brake features help the vehicle maintain a set speed up and down grades, even when towing a heavy trailer.
With the diesel exhaust brake feature, the turbocharger is used to smoothly and quietly create additional backpressure in the engine to help slow the vehicle. The combination of the exhaust brake and the automatic transmission downshifts helps the driver maintain the desired speed, even on steep grades.
New Digital Steering Assist – standard on LT and LTZ double cab and crew cab models, as well as High Country – also enhances driver control, maneuverability and highway stability. It adapts technology similar to active rack-and-pinion systems for the Silverado HD’s recirculating ball power steering system, providing corrections to enhance stability on the highway, enhance stability control assistance and more. It also helps make Silverado HDs feel more maneuverable and responsive to the driver.
The available Rear Vision camera system with dynamic guidelines (standard on LTZ and High Country and included with the Sport Appearance Package and Midnight Edition) provides a view of items behind the vehicle. It can also assist with lining up in front of a trailer.
Testing, manufacturing and factory support
The Silverado HDs are part of full-size truck family that underwent more than 6 million miles of durability testing in the torture chambers at the Milford Proving Ground, over the deserts and mountains of Nevada and across the frozen flats of Kapuskasing, Ontario. They also accumulated more than 7 million real-world miles development, bringing total test miles to more than 13 million.
