For enhanced safety, the front and second-row seat shoulder belts of the Mercedes GLB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Mazda CX-5 doesn’t offer pretensioners for its rear seat belts.

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 CX-5 doesn’t offer pre-crash pretensioners.

The Mercedes GLB has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The CX-5 doesn’t offer knee airbags.

When descending a steep, off-road slope, the GLB’s standard Downhill Speed Regulation allows you to creep down safely. The CX-5 doesn’t offer Downhill Speed Regulation.

Both the GLB and the CX-5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

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 CX-5’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Engine

The GLB’s 2.0 turbo 4-cylinder produces 34 more horsepower (221 vs. 187) and 72 lbs.-ft. more torque (258 vs. 186) than the CX-5’s standard 2.5 DOHC 4-cylinder.

As tested in Car and Driver the Mercedes GLB is faster than the Mazda CX-5:

	GLB	CX-5 4 cyl.	CX-5 turbo 4 cyl.
Zero to 60 MPH	6 sec	7.9 sec	6.2 sec
Zero to 100 MPH	17.1 sec	23.6 sec	16.7 sec
5 to 60 MPH Rolling Start	6.9 sec	8.4 sec	6.7 sec
Quarter Mile	14.7 sec	16.2 sec	14.8 sec
Speed in 1/4 Mile	94 MPH	85 MPH	95 MPH
Top Speed	131 MPH	124 MPH	130 MPH

Fuel Economy and Range

On the EPA test cycle the GLB gets better mileage than the CX-5:

			MPG
GLB
	FWD	2.0 turbo 4-cyl.	24 city/32 hwy
	AWD	2.0 turbo 4-cyl.	22 city/30 hwy
CX-5
	AWD	2.5 turbo 4-cyl.	22 city/27 hwy

In heavy traffic or at stoplights the GLB’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CX-5 doesn’t offer an automatic engine start/stop system.

Transmission

An eight-speed automatic (SMG) is standard on the Mercedes GLB, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the CX-5.

The GLB offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The CX-5 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 CX-5:

	GLB	CX-5	CX-5 Turbo
Front Rotors	13 inches	11.7 inches	12.6 inches
Rear Rotors	12.6 inches	11.9 inches	11.9 inches

The GLB stops much shorter than the CX-5:

	GLB	CX-5
70 to 0 MPH	157 feet	184 feet	Car and Driver
60 to 0 MPH	122 feet	136 feet	Motor Trend
60 to 0 MPH (Wet)	135 feet	144 feet	Consumer Reports

Tires and Wheels

For better traction, the GLB has larger tires than the CX-5 (235/55R18 vs. 225/65R17).

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 CX-5’s standard 65 series tires. The GLB’s optional tires have a lower 45 series profile than the CX-5 Carbon Edition/Premium/Turbo’s 55 series tires.

For better ride, handling and brake cooling the GLB has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CX-5. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the CX-5 Carbon Edition/Premium/Turbo.

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 CX-5 doesn’t offer run-flat tires.

Suspension and Handling

The GLB has standard front and rear gas-charged shocks for better control over choppy roads. The CX-5’s suspension doesn’t offer gas-charged shocks.

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 CX-5’s suspension doesn’t offer adjustable shock absorbers.

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 CX-5 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLB’s wheelbase is 5.2 inches longer than on the CX-5 (111.4 inches vs. 106.2 inches).

The GLB 250 4MATIC handles at .89 G’s, while the CX-5 Turbo Signature pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The GLB 250 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the CX-5 (27.5 seconds @ .63 average G’s vs. 28.5 seconds @ .58 average G’s).

For greater off-road capability the GLB has a greater minimum ground clearance than the CX-5 (7.9 vs. 7.6 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

Passenger Space

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

The GLB has 1 inch more front headroom, .1 inches more front legroom, .3 inches more rear headroom and .1 inches more rear shoulder room than the CX-5.

Cargo Capacity

The GLB’s cargo area provides more volume than the CX-5.

	GLB	CX-5
Second Seat Folded	62 cubic feet	59.3 cubic feet

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLB. The CX-5 doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the GLB’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-5 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

The GLB uses gas struts to support the hood for easier service access. The CX-5 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

Unlike the driver-only memory seat in the CX-5 Preferred/Carbon Edition/Premium/Turbo, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLB’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The CX-5 doesn’t offer an easy entry system.

The power windows standard on both the GLB and the CX-5 have locks to prevent small children from operating them. When the lock on the GLB is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-5 prevents the driver from operating the other windows just as it does the other passengers.

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 CX-5 can only operate the windows from inside the vehicle, with the ignition on.

The GLB’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The CX-5’s power mirror switches are unlit, making them difficult to find at night and operate safely.

The GLB’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-5 Premium/Turbo.

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 CX-5’s mirror doesn’t automatically adjust for backing.

The GLB’s optional 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 CX-5 offers an automatic rear view mirror, but its side mirrors don’t dim.

The GLB offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the CX-5.

The GLB has a 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. Dual zone air conditioning is only available on the CX-5 Select/Preferred/Carbon Edition/Premium/Turbo.

Both the GLB and the CX-5 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 CX-5 doesn’t offer rear air conditioning vents, only heat vents.

The GLB 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 CX-5 doesn’t offer a house-current electrical outlet.

The GLB’s optional Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The CX-5 doesn’t offer an automated parking system.

Model Availability

The GLB is available in both front-wheel drive and four-wheel drive configurations. The CX-5 doesn’t offer a two-wheel drive configuration.
