Safety

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sierra HD are reminded to check the back seat if they opened the rear door before starting out. The F-Super Duty doesn’t offer a back seat reminder.

The Sierra HD (except Base/SLE) 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 F-Super Duty offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

Full-time four-wheel drive is optional on the Sierra HD. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the F-Super Duty.

Both the Sierra HD and the F-Super Duty have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The Sierra HD’s corrosion warranty is 1 year longer than the F-Super Duty’s (6 vs. 5 years).

Reliability

To reliably power the ignition and other systems and to recharge the battery, the Sierra HD has a standard 170-amp alternator. The F-Super Duty’s standard 157-amp alternator isn’t as powerful.

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

F-Super Duty

Standard Battery

720 amps

650 amps

Optional Battery

Engine

The Sierra HD’s 6.6 V8 produces 16 more horsepower (401 vs. 385) and 34 lbs.-ft. more torque (464 vs. 430) than the F-Super Duty’s 6.2 SOHC V8.

Transmission

A 10-speed automatic is standard on the GMC Sierra HD Diesel, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the F-Super Duty.

Tires and Wheels

The Sierra HD has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The F-Super Duty doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The GMC Sierra HD’s independent front suspension is much lighter than the F-Super Duty 4x4’s solid front axle, which allows the Sierra HD’s wheels to react more quickly and accurately to the road’s surface, improving both ride and handling.

The Sierra HD’s independent front suspension is much lighter than the Ford F-Super Duty’s I-beam semi-independent suspension, which allows the Sierra HD’s wheels to react more quickly and accurately to the road’s surface, improving both ride and handling. The twin I-beam design is also expensive to maintain in proper alignment.

The Sierra HD’s optional drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The F-Super Duty doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Sierra HD’s wheelbase is longer than on the F-Super Duty:

Ergonomics

The Sierra HD SLT/AT4/Denali offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The F-Super Duty doesn’t offer a heads-up display.

The Sierra HD’s power parking brake sets with one touch and releases with one touch or automatically. The F-Super Duty’s parking brake has to released manually.

The Sierra HD’s basic available front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The F-Super Duty’s optional power windows’ rear power window switches have to be held the entire time to open them fully.

When the Sierra HD SLT/AT4/Denali is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The F-Super Duty’s mirrors don’t automatically adjust for backing.

The Sierra HD offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The F-Super Duty offers an automatic rear view mirror, but its side mirrors don’t dim.

Bluetooth wireless connectivity is standard on the Sierra HD, connecting the driver and passenger’s cell phones to the vehicle systems. This allows them to use the vehicle’s stereo and hand controls to place calls safely and easily. Bluetooth costs extra on the F-Super Duty.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Sierra HD (except Base/SLE) offers an optional wireless phone charging system (Qi) in the center console. The F-Super Duty doesn’t offer wireless personal charging.
