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 are reminded to check the back seat if they opened the rear door before starting out. The F-150 doesn’t offer a back seat reminder.

Both the Sierra and the F-150 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, daytime running lights, rearview cameras, available four-wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.


The Sierra’s corrosion warranty is 1 year longer than the F-150’s (6 vs. 5 years).


To reliably start during all conditions and help handle large electrical loads, the Sierra has a standard 730-amp battery (850 Diesel). The F-150’s 610-amp battery isn’t as powerful.


The Sierra’s 3.0 turbo diesel produces 27 more horsepower (277 vs. 250) and 20 lbs.-ft. more torque (460 vs. 440) than the F-150’s 3.0 turbo V6 diesel.

As tested in Motor Trend the Sierra SLT/AT4/Denali 6.2 V8 is faster than the Ford F-150:

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Sierra’s fuel efficiency. The F-150 doesn’t offer a system that can shut down part of the engine.

The Sierra Double/Crew Cab’s standard fuel tank has a gallon more fuel capacity than the F-150’s standard fuel tank (24 vs. 23 gallons), for longer range between fill-ups.

Brakes and Stopping

The Sierra stops much shorter than the F-150:

Tires and Wheels

For better traction, the Sierra has larger standard tires than the F-150 (255/70R17 vs. 245/70R17).

The Sierra 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-150 doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Sierra offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The F-150’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Sierra’s wheelbase is longer than on the F-150:

The Sierra 1500 Short Bed Denali Crew Cab 4x4 handles at .77 G’s, while the F-150 Raptor SuperCab pulls only .70 G’s of cornering force in a Motor Trend skidpad test.

The Sierra 1500 Short Bed AT4 Crew Cab executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the F-150 Raptor SuperCab (27.7 seconds @ .73 average G’s vs. 29.2 seconds @ .59 average G’s).

For better maneuverability, the Sierra’s turning circle is tighter than the F-150’s:

The GMC Sierra has a standard CornerStep, which allows for much easier access to the cargo area. A Tailgate Step costs extra on the Ford F-150.

The Sierra has an all welded cargo box to eliminate possible corrosion spots and to provide better chassis stiffness. The cargo box in the F-150 is bolted through the bed to the frame with large bolts. These bolts are a prime area for corrosion to start as the normal flexing of the truck’s chassis causes them to eat through the finish; they can also snag cargo as it slides in and out.

Payload and Towing

The Sierra’s minimum standard towing capacity is much higher than the F-150’s (7400 vs. 5000 pounds).

The Sierra has a much higher standard payload capacity than the F-150:

The Sierra 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-150 doesn’t offer a heads-up display.

The Sierra’s basic optional front and rear power windows all open fully with one touch of the switches and its driver’s window also automatically closes, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The F-150’s basic optional power window switches have to be held the entire time to open or close them. The F-150 XLT/Lariat/King Ranch/Platinum’s rear windows don’t open automatically.

On a hot day the Sierra’s driver can lower all the windows from a distance using the keyless remote (optional feature). The driver of the F-150 can only operate the windows from inside the vehicle, with the ignition on.

When the Sierra 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-150’s mirrors don’t automatically adjust for backing.

Bluetooth wireless connectivity is standard on the Sierra, 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-150.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Sierra (except Base/SLE/Elevation) offers an optional wireless phone charging system (Qi) in the center console. The F-150 doesn’t offer wireless personal charging.

Economic Advantages

Insurance will cost less for the Sierra owner. The Complete Car Cost Guide estimates that insurance for the Sierra will cost $540 less than the F-150 over a five-year period.

According to The Car Book by Jack Gillis, the Sierra is less expensive to operate than the F-150 because typical repairs cost less on the Sierra than the F-150, including $146 less for a water pump and $123 less for fuel injection.


Truck Trend performed a comparison test in its March 2019 issue and they ranked the GMC Sierra 1500 Short Bed AT4 Crew Cab two places higher than the Ford F-150 5.5 ft. bed Limited SuperCrew 4x4.
