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 Kia Sorento doesn’t offer pretensioners for the middle seat belts.

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

The GLB has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Sorento doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the GLB and the Sorento 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, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

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 Sorento doesn’t offer an automatic engine start/stop system.

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 Sorento doesn’t offer an SMG or a conventional manual transmission.

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 Sorento L/LX’s standard 65 series tires. The GLB’s optional tires have a lower 50 series profile than the Sorento S/EX/SX’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 Sorento L/LX. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the Sorento S/EX/SX.

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 Sorento doesn’t offer run-flat tires.

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 Sorento’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 Sorento doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLB’s wheelbase is 2 inches longer than on the Sorento (111.4 inches vs. 109.4 inches).

For greater off-road capability the GLB has a greater minimum ground clearance than the Sorento (7.9 vs. 7.3 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

Unlike the driver-only memory seat and mirrors in the Sorento SX, 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 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 Sorento 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 Sorento’s parking brake has to released manually.

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 Sorento’s standard 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 Sorento 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 Sorento’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors available for the GLB detect other vehicles which could be blinded and automatically switch to low beams. The Sorento doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The Sorento 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 side window demisters help clear frost or condensation from the side windows in the winter. The Sorento doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

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 Sorento offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the GLB’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Sorento doesn’t offer a heated steering wheel.

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 Sorento.

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 costs extra on the Sorento and isn’t available on the Sorento L.

The GLB’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Sorento L doesn’t offer automatic air conditioning.

The GLB’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Sorento’s navigation system doesn’t offer real-time traffic updates.

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 Sorento 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 Sorento doesn’t offer an automated parking system.
