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 Chevrolet Blazer 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 Blazer doesn’t offer Downhill Speed Regulation.

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 Blazer doesn’t offer a driver alert monitor.

Both the GLB and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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.

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 Blazer 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 Blazer’s standard 65 series tires.

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 Blazer 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 Blazer’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 Blazer doesn’t offer drift compensation steering.

For greater off-road capability the GLB has a greater minimum ground clearance than the Blazer (7.9 vs. 7.4 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

Unlike the driver-only memory system optional at extra cost in the Blazer (except L/LT), the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) 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 Blazer 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 Blazer’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 Blazer can only close 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 Blazer’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 Blazer 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 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Blazer.

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