For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX50 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Chevrolet Blazer doesn’t offer pretensioners for its rear seat belts.

The Infiniti QX50 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Blazer doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The QX50 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Blazer doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX50. But it costs extra on the Blazer.

The QX50 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Blazer’s blind spot costs extra.

To help make backing out of a parking space safer, the QX50 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Chevrolet charges extra for Rear Cross Traffic Alert on the Blazer.

Both the QX50 and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Infiniti QX50 is safer than the Chevrolet Blazer:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

The QX50 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Blazer’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX50 1 year and 10,000 miles longer than Chevrolet covers the Blazer. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Blazer ends after only 5 years or 60,000 miles.

The QX50’s corrosion warranty is 1 year and unlimited miles longer than the Blazer’s (7/unlimited vs. 6/100,000).

Infiniti pays for scheduled maintenance on the QX50 for 3 years and 22500 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Chevrolet only pays for the first scheduled maintenance visit on the Blazer.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the QX50’s reliability 16 points higher than the Blazer.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Infiniti vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Infiniti 7 places higher in reliability than Chevrolet.

Engine

The QX50’s 2.0 turbo 4-cylinder produces 40 more horsepower (268 vs. 228) and 22 lbs.-ft. more torque (280 vs. 258) than the Blazer’s standard 2.0 turbo 4-cylinder. The QX50’s 2.0 turbo 4-cylinder produces 10 lbs.-ft. more torque (280 vs. 270) than the Blazer’s optional 3.6 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the QX50 gets better mileage than the Blazer:

			MPG
QX50
	AWD	2.0 turbo 4-cyl.	22 city/28 hwy
Blazer
	FWD	3.6 DOHC V6	19 city/26 hwy
	AWD	3.6 DOHC V6	18 city/26 hwy
		2.0 turbo 4-cyl.	22 city/27 hwy

The QX50 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Blazer. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Transmission

The QX50 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Blazer doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the QX50’s front brake rotors are larger than those on the Blazer:

	QX50	Blazer
Front Rotors	13 inches	12.64 inches

The QX50’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Blazer are solid, not vented.

The QX50 stops shorter than the Blazer:

	QX50	Blazer
60 to 0 MPH	121 feet	126 feet	Motor Trend
60 to 0 MPH (Wet)	130 feet	139 feet	Consumer Reports

Tires and Wheels

The QX50’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Blazer’s standard 65 series tires.

For better ride, handling and brake cooling the QX50 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Blazer.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Blazer doesn’t offer run-flat tires.

Suspension and Handling

The QX50 handles at .84 G’s, while the Blazer RS 4x4 pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The QX50 executes Motor Trend’s “Figure Eight” maneuver quicker than the Blazer RS 4x4 (26.7 seconds @ .66 average G’s vs. 27.3 seconds @ .67 average G’s).

For better maneuverability, the QX50’s turning circle is 2.3 feet tighter than the Blazer’s (36.4 feet vs. 38.7 feet).

For greater off-road capability the QX50 has a 1.1 inches greater minimum ground clearance than the Blazer LT (8.6 vs. 7.5 inches), allowing the QX50 to travel over rougher terrain without being stopped or damaged. The QX50’s minimum ground clearance is 1 inch higher than on the Blazer RS/Premier (8.6 vs. 7.6 inches).

Chassis

The QX50 is 7.1 inches shorter than the Blazer, making the QX50 easier to handle, maneuver and park in tight spaces.

Passenger Space

The QX50 has 1.2 inches more front headroom and .5 inches more rear headroom than the Blazer.

The front step up height for the QX50 is 1.2 inches lower than the Blazer (17.2” vs. 18.4”). The QX50’s rear step up height is 1.3 inches lower than the Blazer’s (17.7” vs. 19”).

Cargo Capacity

The QX50 has a larger cargo volume with its rear seat up than the Blazer with its rear seat up (31.4 vs. 30.5 cubic feet). The QX50 has a larger cargo volume with its rear seat folded than the Blazer with its rear seat folded (65.1 vs. 64.2 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the QX50 easier. The QX50’s cargo hatch lift-over height is 27.7 inches, while the Blazer’s liftover is 30.3 inches.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the QX50. The Blazer doesn’t offer locking storage for small valuables.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Chevrolet. J.D. Power ranks Infiniti 6th in service department satisfaction (above the industry average). With a 21% lower rating, Chevrolet is ranked 14th.

Ergonomics

The QX50’s front and rear power windows all open or close 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 Blazer’s passenger windows don’t close automatically.

If the windows are left open on the QX50 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Blazer can only close the windows from inside the vehicle, with the ignition on.

The QX50’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 Blazer’s manually variable intermittent wipers have to be constantly adjusted. The QX50 Sport’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

Manual rear side window sunshades are available in the QX50 to help block heat and glare for the rear passengers. The Blazer doesn’t offer rear side window sunshades.

Both the Infiniti QX50 and Chevrolet Blazer offer exterior mirrors that can be folded to provide convenience. The QX50 offers available power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Blazer’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX50 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Blazer.

Economic Advantages

According to The Car Book by Jack Gillis, the QX50 is less expensive to operate than the Blazer because it costs $618 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the QX50 than the Blazer, including $116 less for front brake pads, $11 less for a fuel pump and $362 less for a timing belt/chain.
