Compare the2025 Mercedes GLBVS 2025 Kia Sportage Hybrid

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 Kia Sportage Hybrid 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 Sportage Hybrid 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 Sportage Hybrid doesn’t offer knee airbags.

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. Only the Sportage Hybrid EX/SX-Prestige offers a blind spot warning system.

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. Only the Sportage Hybrid EX/SX-Prestige offers Rear Cross-Traffic Collision Warning.

Both the GLB and the Sportage Hybrid 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, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.

The GLB’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Sportage Hybrid runs out after 100,000 miles.

Both the GLB and Sportage Hybrid have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. The GLB has a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily.

The GLB has 2.2 gallons more fuel capacity than the Sportage Hybrid (15.9 vs. 13.7 gallons), for longer range between fill-ups.

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 Sportage Hybrid.

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

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

	GLB	Sportage Hybrid
Front Rotors	13 inches	12.6 inches
Rear Rotors	12.6 inches	11.8 inches

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 Sportage LX HEV’s standard 65 series tires. The GLB’s optional tires have a lower 45 series profile than the Sportage Hybrid EX/SX-Prestige’s 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 Sportage LX HEV. The GLB’s optional 20-inch wheels are larger than the 18-inch wheels on the Sportage Hybrid EX/SX-Prestige.

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 Sportage Hybrid 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 Sportage Hybrid’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 Sportage Hybrid doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLB’s wheelbase is 2.9 inches longer than on the Sportage Hybrid (111.4 inches vs. 108.5 inches).

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

The GLB has 1.1 inches more front headroom and .2 inches more rear headroom than the Sportage Hybrid.

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

The GLB uses gas struts to support the hood for easier service access. The Sportage Hybrid 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.

Unlike the driver-only memory seat and mirrors in the Sportage Hybrid SX-Prestige, 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 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 Sportage Hybrid doesn’t offer a heads-up display.

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 Sportage Hybrid’s standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically. With the Sportage Hybrid EX/SX-Prestige’s power windows, only the front windows 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 Sportage Hybrid can only close 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. Push Button Start standard on the Sportage Hybrid only offers hands-free access for the ignition, none to unlock the vehicle. Push Button Start is not available on the Sportage Hybrid EX/SX-Prestige.

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 Sportage Hybrid’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 Sportage Hybrid 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. Kia charges extra for heated mirrors on the Sportage Hybrid.

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

Both the Mercedes GLB and Kia Sportage Hybrid 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 Sportage Hybrid’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The Mercedes GLB has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Kia charges extra for Homelink® on the Sportage Hybrid.

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 Sportage Hybrid EX/SX-Prestige offers wireless charging.

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 Sportage Hybrid doesn’t offer a house-current electrical outlet.

The GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLB will retain 61.32% of its original price after five years, while the Sportage Hybrid only retains 52.49% to 53.39%.
