For enhanced safety, the front and rear seat shoulder belts of the Toyota Tundra are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Sierra doesn’t offer height-adjustable seat belts.

The Tundra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Sierra doesn’t offer a driver alert monitor.

Both the Tundra and the Sierra 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, blind spot warning systems, rear parking sensors and rear cross-path warning.


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


For smoother operation, better efficiency and fewer moving parts, the engines in the Tundra have an overhead cam design, rather than the old pushrod design of some of the engines in the Sierra.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Toyota Tundra uses regular unleaded gasoline. The Sierra SLT/AT4/Denali requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Tundra’s standard fuel tank has 2.4 gallons more fuel capacity than the Sierra Double/Crew Cab’s standard fuel tank (26.4 vs. 24 gallons), for longer range between fill-ups. The Tundra Limited/Platinum/1794/TRD Pro’s standard fuel tank has 10 gallons more fuel capacity than the Sierra Regular Cab’s standard fuel tank (38 vs. 28 gallons).

Brakes and Stopping

For better stopping power the Tundra’s front brake rotors are larger than those on the Sierra:




Front Rotors

13.9 inches

13.5 inches

Tires and Wheels

For better ride, handling and brake cooling the Tundra has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Sierra.

The Tundra has a standard full size spare so a flat doesn’t interrupt your work or a trip. A full size spare costs extra on the Sierra. Without the option you must depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling

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

For a smoother ride and more stable handling, the Tundra Long Bed Double Cab’s wheelbase is 7.6 inches longer than on the Sierra 1500 Standard Bed Crew Cab (164.6 feet vs. 157 inches).

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




Extended Cab Standard Bed

44 feet

46.3 feet

Crew Cab Short Bed

44 feet

46.3 feet

Extended Cab Standard Bed 4x4

44 feet

46.3 feet

Crew Cab Short Bed 4x4

44 feet

46.3 feet


The Tundra is shorter than the Sierra, making the Tundra easier to handle, maneuver and park in tight spaces:




Extended Cab Standard Bed

228.9 inches

231.7 inches

Crew Cab Short Bed

228.9 inches

231.7 inches

Passenger Space

The Tundra Double Cab has 1.4 inches more front hip room, 2.4 inches more rear hip room and .7 inches more rear shoulder room than the Sierra Double Cab.

The Tundra CrewMax has 1.4 inches more front hip room, .2 inches more rear hip room and .3 inches more rear shoulder room than the Sierra Crew Cab.

For enhanced passenger comfort on long trips the Tundra CrewMax’s rear seats recline. The Sierra’s optional rear seats don’t recline.

Cargo Capacity

The Toyota Tundra has a standard Easy Lower and Lift Tailgate, which prevents the heavy tailgate from falling with a crash and causing injury. It allows adults and children to easily open and close the tailgate with one hand to better facilitate loading and unloading. Tailgate assist costs extra on the GMC Sierra.

Both the Tundra and Sierra have bed indentations that accommodate 2x4’s for two-tiered loading, but the Tundra also has indentations to separate the cargo box into three different sections length-wise.


To better shield the driver and front passenger’s vision, the Tundra Limited has standard dual-element sun visors that can block glare from two directions simultaneously. The Sierra doesn’t offer secondary sun visors.

The Tundra has standard power remote mirrors. The Sierra only comes with remote mirrors at extra cost. Without them the driver will have to roll down the windows and reach across the car to adjust the mirrors.

The Tundra’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. GMC charges extra for heated mirrors on the Sierra.

To keep a safe, consistent following distance, the Tundra has a standard Dynamic Radar 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 doesn’t offer an adaptive cruise control.

Economic Advantages

The Tundra will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Tundra will retain 53.8% to 78.42% of its original price after five years, while the Sierra only retains 53.16% to 57.57%.
