The Ram HD offers optional Automatic Emergency Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Sierra HD offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

Over 200 people are killed each year when backed over by motor vehicles. The Ram HD offers optional Reverse Stop that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Sierra HD doesn’t offer backup collision prevention brakes.

The Ram HD offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The Sierra HD only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing safer, the Ram HD’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Sierra HD doesn’t offer a cross-path warning system.

Both the Ram HD and the Sierra HD have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available four-wheel drive, lane departure warning systems and blind spot warning systems.

The Ram HD’s corrosion warranty is unlimited miles longer than the Sierra HD’s (unlimited vs. 100,000 miles).

There are over 38 percent more Ram dealers than there are GMC dealers, which makes it easier should you ever need service under the HD’s warranty.

The Ram HD has a solid front axle with a floating power axle for durability that the Sierra HD 4x4’s independent front suspension and exposed front driveshafts don’t offer.

To reliably power the ignition and other systems and to recharge the battery, the Ram HD has a standard 180-amp alternator. The Sierra HD’s standard 150-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Ram HD offers larger standard and optional batteries than the Sierra HD:

An engine control system that can shut down some of the engine’s cylinders helps improve the Ram HD V8’s fuel efficiency. The Sierra HD doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the Ram HD Gas’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Sierra HD doesn’t offer an automatic engine start/stop system.

The Ram HD Long Bed Crew Cab’s standard fuel tank has 14 gallons more fuel capacity than the Sierra HD (50 vs. 36 gallons).

The Ram HD has standard front and rear stabilizer bars, which help keep the Ram HD flat and controlled during cornering. The Sierra HD’s suspension doesn’t offer a rear stabilizer bar.

The Ram HD Power Wagon has an active front sway bar, which helps keep it flat and controlled during cornering, but disconnects at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Sierra HD doesn’t offer an active sway bar system.

The front suspension of the Ram HD uses coil springs for better ride, handling and control than the Sierra HD, which uses torsion bars in front. Coil springs compress more progressively and offer more suspension travel for a smoother ride with less bottoming out.

The Ram HD 2500 has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The Sierra HD doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Ram HD 2500 Long Box Crew Cab’s wheelbase is 1.3 inches longer than on the Sierra 2500 Long Box Crew Cab (169 inches vs. 167.7 inches).

For better maneuverability, the Ram HD’s turning circle is tighter than the Sierra HD’s:

The Ram HD may be more efficient, handle and accelerate better because it weighs about 250 to 700 pounds less than the GMC Sierra HD.

The front grille of the Ram HD uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Sierra HD doesn’t offer active grille shutters.

The Ram HD offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Sierra HD doesn’t offer active noise cancellation.

The Ram HD Crew Cab/Mega Cab’s front power windows both open or close with one touch of the switches. The Sierra HD ’s front passenger window doesn’t close automatically.

Keyless Go standard on the Ram HD allows you to start the engine without removing a key from pocket or purse (optional Keyless Enter ‘n Go will also allow unlocking the driver’s door and tailgate without taking your keys out). The GMC Sierra HD doesn’t offer an advanced key system.

The Ram HD’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Sierra HD’s manually variable intermittent wipers have to be constantly adjusted. The Ram HD’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

While driving with high beams on, sensitive light sensors available for the Ram HD detect other vehicles which could be blinded and automatically switch to low beams. The Sierra HD doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the Ram HD offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Sierra HD doesn’t offer cornering lights.

Both the Ram HD and the Sierra HD offer rear vents. For greater rear passenger comfort, the Ram HD has standard rear air-conditioning vents to keep rear occupants cool in summer or warm in winter. The Sierra HD doesn’t offer rear air-conditioning vents, only heat vents.

To keep a safe, consistent following distance, the Ram HD offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Sierra HD doesn’t offer an adaptive cruise control.
