Compare the2024 Chevrolet BlazerVS 2023 Mercedes GLB

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 Mercedes GLB doesn’t offer comfort guides on its rear 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 GLB doesn’t offer a back seat reminder.

The Blazer’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLB.

Both the Blazer and the GLB 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Blazer the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The GLB has not been tested, yet.

Chevrolet’s powertrain warranty covers the Blazer 1 year and 10,000 miles longer than Mercedes covers the GLB. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLB ends after only 4 years or 50,000 miles.

The Blazer’s corrosion warranty is 1 year longer than the GLB’s (6 vs. 5 years).

There are almost 8 times as many Chevrolet dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Blazer’s warranty.

The Blazer’s standard 2.0 turbo 4-cylinder produces 7 more horsepower (228 vs. 221) than the GLB’s 2.0 turbo 4-cylinder. The Blazer’s optional 3.6 DOHC V6 produces 87 more horsepower (308 vs. 221) and 12 lbs.-ft. more torque (270 vs. 258) than the GLB’s 2.0 turbo 4-cylinder.

As tested in Motor Trend the Chevrolet Blazer V6 is faster than the Mercedes GLB:

An engine control system that can shut down some of the engine’s cylinders helps improve the Blazer V6’s fuel efficiency. The GLB doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Chevrolet Blazer uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cylinder engine for maximum performance). The GLB requires premium, which can cost on average about 82.8 cents more per gallon.

The Blazer FWD’s standard fuel tank has 3.5 gallons more fuel capacity than the GLB (19.4 vs. 15.9 gallons), for longer range between fill-ups. The Blazer AWD’s standard fuel tank has 5.8 gallons more fuel capacity than the GLB (21.7 vs. 15.9 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 GLB doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Chevrolet Blazer higher (6 to 7 out of 10) than the Mercedes GLB (5). This means the Blazer produces up to 8 pounds less smog-producing pollutants than the GLB every 15,000 miles.

A nine-speed automatic is standard on the Chevrolet Blazer, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the GLB.

The Blazer stops shorter than the GLB:

For better traction, the Blazer RS/Premier’s optional tires are larger than the largest tires available on the GLB (265/45R21 vs. 235/55R18).

For better ride, handling and brake cooling the Blazer RS/Premier offers optional 21-inch wheels. The GLB’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 Mercedes GLB only has 5 wheel lugs per wheel.

The Blazer 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 GLB doesn’t offer vehicle monitored tire inflation.

The Blazer 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 GLB; 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. Some tire options on the GLB don’t have a run-flat feature, either.

For a smoother ride and more stable handling, the Blazer’s wheelbase is 1.3 inches longer than on the GLB (112.7 inches vs. 111.4 inches).

For better handling and stability, the track (width between the wheels) on the Blazer is 3.2 inches wider in the front and 3 inches wider in the rear than on the GLB.

The Blazer RS 4x4 handles at .83 G’s, while the GLB 250 4MATIC pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The Blazer RS 4x4 executes Motor Trend’s “Figure Eight” maneuver quicker than the GLB 250 4MATIC (27.1 seconds @ .65 average G’s vs. 27.5 seconds @ .63 average G’s).

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 GLB doesn’t offer active grille shutters.

The Blazer uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLB doesn’t offer active noise cancellation.

The Blazer has 3.2 inches more front shoulder room, 1.5 inches more rear legroom and 3.7 inches more rear shoulder room than the GLB.

The Blazer has a much larger cargo volume with its rear seat up than the GLB with its rear seat up (30.5 vs. 5.1 cubic feet). The Blazer has a much larger cargo volume with its rear seat folded than the GLB with its rear seat folded (64.2 vs. 62 cubic feet).

Pulling a handle automatically lowers the Blazer’s rear seats, to make changing between passengers and cargo easier. The GLB doesn’t offer automatic folding seats.

The Blazer has a 1500 lbs. towing capacity. The GLB has no towing capacity.

The Blazer can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Blazer can be unhitched and driven around locally. The GLB can’t be towed flat on the ground.

Standard Trailer Sway Control on the Blazer uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The GLB doesn’t offer electronic trailer sway control.

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 GLB does not have an oil pressure gauge.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Blazer LT/RS/Premier’s available exterior PIN entry system. The GLB doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

To improve rear visibility by keeping the rear window clear, the Blazer has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLB only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the Blazer’s headlight performance “Very Good,” a higher rating than the GLB’s headlights, which were rated “Fair.”

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Blazer has standard extendable sun visors. The GLB doesn’t offer extendable visors.

Both the Blazer and the GLB offer optional heated front seats. The Blazer RS/Premier also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.
