For enhanced safety, the front shoulder belts of the Chevrolet Blazer are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Infiniti QX50 has only front height-adjustable seat belts.
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 Blazer are reminded to check the back seat if they opened the rear door before starting out. The QX50 doesn’t offer a back seat reminder.
Both the Blazer and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, 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 crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
There are over 14 times as many Chevrolet dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Blazer’s warranty.
To reliably power the ignition and other systems and to recharge the battery, the Blazer has a standard 150-amp alternator (155-amp - Blazer V6 FWD and 170 V6 AWD/2.0 Turbo). The QX50’s 130-amp alternator isn’t as powerful.
J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 16 more problems per 100 vehicles, Infiniti is ranked 19th, below the industry average.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Chevrolet fourth in reliability, above the industry average. With 13 more problems per 100 vehicles, Infiniti is ranked 11th.
The Blazer’s optional 3.6 DOHC V6 produces 40 more horsepower (308 vs. 268) than the QX50’s 2.0 turbo 4-cylinder.
As tested in Consumer Reports the Chevrolet Blazer V6 is faster than the Infiniti QX50:
Zero to 30 MPH
Zero to 60 MPH
45 to 65 MPH Passing
Speed in 1/4 Mile
An engine control system that can shut down half of the engine’s cylinders helps improve the Blazer V6’s fuel efficiency. The QX50 doesn’t offer a system that can shut down part of the engine.
In heavy traffic or at stoplights the Blazer’s 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 QX50 doesn’t offer an automatic engine start/stop system.
To lower fuel costs and make buying fuel easier, the Chevrolet Blazer uses regular unleaded gasoline (premium recommended with the 2.0 turbo for maximum performance). The QX50 requires premium, which can cost 20 to 55 cents more per gallon.
The Blazer FWD’s standard fuel tank has 3.4 gallons more fuel capacity than the QX50 (19.4 vs. 16 gallons), for longer range between fill-ups. The Blazer AWD’s standard fuel tank has 5.7 gallons more fuel capacity than the QX50 (21.7 vs. 16 gallons).
The Blazer has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX50 doesn’t offer a cap-less fueling system.
For better traction, the Blazer RS/Premier’s optional tires are larger than the largest tires available on the QX50 (265/45R21 vs. 255/45R20).
For better ride, handling and brake cooling the Blazer RS/Premier offers optional 21-inch wheels. The QX50’s largest wheels are only 20-inches.
The Chevrolet Blazer’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Infiniti QX50 only has 5 wheel lugs per wheel.
The Blazer LT/RS/Premier has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the QX50; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
For a smoother ride and more stable handling, the Blazer’s wheelbase is 2.5 inches longer than on the QX50 (112.7 inches vs. 110.2 inches).
For better handling and stability, the track (width between the wheels) on the Blazer is 2.1 inches wider in the front and 2.2 inches wider in the rear than the average track on the QX50.
The front grille of the Blazer uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX50 doesn’t offer active grille shutters.
The Blazer has 3.4 cubic feet more passenger volume than the QX50 (107.8 vs. 104.4).
The Blazer has 1.4 inches more front legroom, 1.2 inches more front shoulder room, .9 inches more rear legroom, .4 inches more rear hip room and 1.5 inches more rear shoulder room than the QX50.
Pressing a switch automatically lowers the Blazer’s rear seats, to make changing between passengers and cargo easier. The QX50 doesn’t offer automatic folding seats.
The Blazer’s standard towing capacity is much higher than the QX50’s (1500 vs. 0 pounds). Maximum trailer towing in the Infiniti QX50 AWD is only 3000 pounds. The Blazer 4x4 offers up to a 4500 lbs. towing capacity.
The Blazer’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX50 does not have an oil pressure gauge.
The power windows standard on both the Blazer and the QX50 have locks to prevent small children from operating them. When the lock on the Blazer is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.
Consumer Reports rated the Blazer’s headlight performance “Very Good,” a higher rating than the QX50’s headlights, which were rated “Good.”
The Blazer’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential.
The Blazer 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 QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.
Both the Blazer and the QX50 offer available heated front seats. The Blazer also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Chevrolet Blazer RS/Premier offers an optional wireless phone charging system (Qi) in the center console. The QX50 doesn’t offer wireless personal charging.
The Blazer (except L) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX50 doesn’t offer a house-current electrical outlet.
J.D. Power and Associates rated the Blazer first among midsize SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The QX50 isn’t in the top three.
