For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Nissan Rogue doesn’t offer pretensioners for the middle seat belts.
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 Rogue doesn’t offer a driver alert monitor.
Both the GLB and the Rogue have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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, lane departure warning systems, blind spot warning systems and around view monitors.
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 Rogue’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Nissan vehicles. J.D. Power ranks Mercedes 13th in reliability, above the industry average. With 3 more problems per 100 vehicles, Nissan is ranked 15th.
The GLB’s 2.0 turbo 4-cylinder produces 51 more horsepower (221 vs. 170) and 83 lbs.-ft. more torque (258 vs. 175) than the Rogue’s 2.5 DOHC 4-cylinder.
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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Rogue doesn’t offer an automatic engine start/stop system.
The GLB has 1.4 gallons more fuel capacity than the Rogue (15.9 vs. 14.5 gallons), for longer range between fill-ups.
For better stopping power the GLB’s brake rotors are larger than those on the Rogue:
For better traction, the GLB has larger tires than the Rogue (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 Rogue S/SV’s standard 65 series tires. The GLB’s optional tires have a lower 50 series profile than the Rogue SL’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 Rogue S/SV. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the Rogue SL.
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 Rogue’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 Rogue doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the GLB’s wheelbase is 4.9 inches longer than on the Rogue (111.4 inches vs. 106.5 inches).
The design of the Mercedes GLB amounts to more than styling. The GLB has an aerodynamic coefficient of drag of .32 Cd. That is lower than the Rogue (.319 to .336) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLB get better fuel mileage.
The GLB offers optional seating for 7 passengers; the Rogue can only carry 5.
The GLB has .8 inches more rear headroom and .2 inches more rear legroom than the Rogue.
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLB. The Rogue doesn’t offer locking storage for small valuables.
The GLB uses gas struts to support the hood for easier service access. The Rogue 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.
J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Nissan. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 38% lower rating, Nissan is ranked 17th.
To help each driver find a more comfortable driving position, the GLB has a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The Rogue doesn’t offer a telescoping steering wheel.
Unlike the driver-only memory seat and mirrors optional at extra cost in the Rogue (except S), the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle 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 Rogue 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 Rogue doesn’t offer a heads-up display.
The GLB’s power parking brake sets with one touch and releases with one touch or automatically. The Rogue’s parking brake has to released manually.
The power windows standard on both the GLB and the Rogue 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 Rogue prevents the driver from operating the other windows just as it does the other passengers.
The GLB’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Rogue’s passenger windows don’t open or 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 Rogue can only operate the windows from inside the vehicle, with the ignition on.
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 Rogue’s manually variable intermittent wipers have to be constantly adjusted.
To help drivers avoid possible obstacles, the GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The Rogue 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. Nissan charges extra for heated mirrors on the Rogue.
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 Rogue’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 Rogue offers an automatic rear view mirror, but its side mirrors don’t dim.
Optional air-conditioned seats in the GLB keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Rogue doesn’t offer air-conditioned seats.
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 Rogue.
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 Rogue SV/SL.
The GLB has a 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 Rogue 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 Rogue doesn’t offer an automated parking system.
