The GLB’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Trailblazer doesn’t offer pre-crash pretensioners.

The GLB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Trailblazer only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The GLB 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. A system to reveal vehicles in the Trailblazer’s blind spot costs extra.

To help make backing out of a parking space safer, the GLB has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Trailblazer and the Trailblazer’s Rear Cross Traffic Alert does not include automatic braking.

The GLB’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 Trailblazer doesn’t offer a driver alert monitor.

Both the GLB and the Trailblazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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 and lane departure warning systems.

Warranty

The GLB comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Trailblazer’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

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

Reliability

A hardened steel chain, with no maintenance needs, drives the camshafts in the GLB’s engine. A rubber cam drive belt that needs periodic replacement drives the Trailblazer’s camshafts. If the Trailblazer’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

Engine

The GLB’s 2.0 turbo 4-cylinder hybrid produces 84 more horsepower (221 vs. 137) and 96 lbs.-ft. more torque (258 vs. 162) than the Trailblazer’s standard 1.2 turbo 3-cylinder. The GLB’s 2.0 turbo 4-cylinder hybrid produces 66 more horsepower (221 vs. 155) and 84 lbs.-ft. more torque (258 vs. 174) than the Trailblazer’s optional 1.3 turbo 3-cylinder.

As tested in Motor Trend the Mercedes GLB is faster than the Chevrolet Trailblazer 1.3 turbo 3-cylinder:

	GLB	Trailblazer
Zero to 60 MPH	6.2 sec	9.3 sec
Quarter Mile	14.8 sec	17 sec
Speed in 1/4 Mile	94.1 MPH	80.5 MPH

Fuel Economy and Range

On the EPA test cycle the GLB 250 4MATIC gets better fuel mileage than the Trailblazer 1.3 turbo 3-cylinder 9-speed Auto AWD (24 city/33 hwy vs. 26 city/29 hwy).

Regenerative brakes improve the GLB’s fuel efficiency by converting inertia back into energy instead of wasting it. The Trailblazer doesn’t offer a regenerative braking system.

The GLB has 2.7 gallons more fuel capacity than the Trailblazer (15.9 vs. 13.2 gallons), for longer range between fill-ups.

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

Transmission

The GLB offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is more internally efficient than a CVT but just as easy to drive. The Trailblazer doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the GLB’s brake rotors are larger than those on the Trailblazer:

	GLB	Trailblazer
Front Rotors	13 inches	11.81 inches
Rear Rotors	12.6 inches	10.39 inches

Tires and Wheels

For better traction, the GLB has larger tires than the Trailblazer (235/55R18 vs. 225/60R17).

The GLB’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 Trailblazer LS/LT/ACTIV’s standard 60 series tires.

For better ride, handling and brake cooling the GLB has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Trailblazer LS/LT/ACTIV. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the Trailblazer RS.

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

Suspension and Handling

For superior ride and handling, the Mercedes GLB has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Trailblazer has a rear torsion beam axle, with a semi-independent rear suspension.

The GLB has standard front and rear stabilizer bars, which help keep the GLB flat and controlled during cornering. The Trailblazer’s suspension doesn’t offer a rear stabilizer bar.

The GLB offers an optional 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 or off-road. The Trailblazer’s suspension doesn’t offer adjustable shock absorbers.

The GLB has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Trailblazer doesn’t offer variable-assist power steering.

The GLB’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Trailblazer doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLB’s wheelbase is 7.5 inches longer than on the Trailblazer (111.4 inches vs. 103.9 inches).

For better handling and stability, the track (width between the wheels) on the GLB is 1.6 inches wider in the front and 1.2 inches wider in the rear than on the Trailblazer.

The GLB’s front to rear weight distribution is more even (57% to 43%) than the Trailblazer’s (60% to 40%). This gives the GLB more stable handling and braking.

The GLB 250 4MATIC handles at .83 G’s, while the Trailblazer RS AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The GLB 250 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the Trailblazer RS AWD (27.4 seconds @ .62 average G’s vs. 28.3 seconds @ .57 average G’s).

Passenger Space

The GLB offers optional seating for 7 passengers; the Trailblazer can only carry 5.

The GLB has .7 inches more front headroom, .2 inches more front legroom, .5 inches more front shoulder room, .9 inches more rear headroom and 1.1 inches more rear shoulder room than the Trailblazer.

For enhanced passenger comfort on long trips the GLB’s middle row seats recline. The Trailblazer’s rear seats don’t recline.

Cargo Capacity

The GLB’s cargo area provides more volume than the Trailblazer.

	GLB	Trailblazer
Second Seat Folded	62 cubic feet	54.4 cubic feet

A low lift-over cargo hatch design makes loading and unloading the GLB easier. The GLB’s cargo hatch lift-over height is 28.5 inches, while the Trailblazer’s liftover is 30.8 inches.

The GLB’s cargo area is larger than the Trailblazer’s in almost every dimension:

	GLB	Trailblazer
Length to seat (2nd/1st)	32.5”/71”	32”/64.5”
Max Width	41.6”	54”
Min Width	41.6”	41”
Height	37.2”	28.2”

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

Servicing Ease

The GLB uses gas struts to support the hood for easier service access. The Trailblazer uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

When three different drivers share the GLB, the memory system makes it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations. The Trailblazer doesn’t offer a memory system.

The GLB’s standard easy entry and exit feature glides the driver’s seat back, making it easier for the driver to get in and out. The Trailblazer doesn’t offer an easy entry system.

The GLB offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Trailblazer doesn’t offer a heads-up display.

The GLB’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 Trailblazer’s passenger windows don’t close automatically.

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

The GLB’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Start standard on the Trailblazer only offers hands-free access for the ignition, none to unlock the vehicle. Keyless Start is not available on the Trailblazer LT/ACTIV/RS.

The GLB’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Trailblazer’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are optional on the GLB to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Trailblazer doesn’t offer heated windshield washer nozzles.

To help drivers avoid possible obstacles, the GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The Trailblazer doesn’t offer cornering lights. The GLB also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The GLB’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Chevrolet only offers heated mirrors on the Trailblazer LT/ACTIV/RS.

When the GLB is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Trailblazer’s mirror doesn’t automatically adjust for backing.

The GLB’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Trailblazer offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Mercedes GLB and Chevrolet Trailblazer offer exterior mirrors that can be folded to provide convenience. The GLB features standard 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 Trailblazer’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The GLB has a standard center folding armrest for the middle row passengers. A center armrest helps make middle row passengers more comfortable and it can provide a boundary between children. The Trailblazer LS doesn’t offer a rear seat center armrest.

The GLB’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Trailblazer doesn’t offer dual zone air conditioning.

Both the GLB and the Trailblazer offer rear vents. For greater rear passenger comfort, the GLB has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Trailblazer doesn’t offer rear air conditioning vents, only heat vents.

Compared to the Chevrolet Trailblazer, the Mercedes GLB eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries with its standard integrated Homelink® universal remote controlled from the rear view mirror.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLB has a standard wireless phone charging system (Qi) in the center console. Only the Trailblazer LT/ACTIV/RS offers wireless charging and it costs extra.

The GLB’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Trailblazer doesn’t offer an automated parking system.
