Compare the2024 Genesis GV70VS 2023 Mercedes GLB

Both the GV70 and GLB have child safety locks to prevent children from opening the rear doors. The GV70 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLB’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GV70 are reminded to check the back seat if they opened the rear door before starting out. The GLB doesn’t offer a back seat reminder.

The GV70 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GLB doesn’t offer front seat center airbags.

Using vehicle speed sensors and seat sensors, smart airbags in the GV70 deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The GV70’s side airbags will shut off if a child is leaning against the door. The GLB’s side airbags don’t have smart features and will always deploy full force.

Over 200 people are killed each year when backed over by motor vehicles. The GV70 Advanced/Prestige has a standard Reverse Parking Collision-Avoidance Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GV70. But it costs extra on the GLB.

The GV70’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLB.

Both the GV70 and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning, driver alert monitors and available around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GV70 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The GLB has not been tested, yet.

The GV70 comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes free 24-hour roadside assistance. The GLB’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Genesis’ powertrain warranty covers the GV70 6 years and 50,000 miles longer than Mercedes covers the GLB. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the GLB ends after only 4 years or 50,000 miles.

The GV70’s corrosion warranty is 2 years longer than the GLB’s (7 vs. 5 years).

Genesis pays for scheduled maintenance on the GV70 for 3 years and 36,000 miles. Genesis will pay for oil changes, tire rotations, air filter replacements, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLB.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the GV70’s reliability 21 points higher than the GLB.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Genesis above average in initial quality. With 25 more problems per 100 vehicles, Mercedes is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Genesis vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Genesis fourth in reliability, above the industry average. With 40 more problems per 100 vehicles, Mercedes is ranked 18th.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Genesis vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Genesis 12 places higher in reliability than Mercedes.

The GV70’s standard 2.5 turbo 4-cylinder produces 79 more horsepower (300 vs. 221) and 53 lbs.-ft. more torque (311 vs. 258) than the GLB’s 2.0 turbo 4-cylinder. The GV70’s optional 3.5 turbo V6 produces 154 more horsepower (375 vs. 221) and 133 lbs.-ft. more torque (391 vs. 258) than the GLB’s 2.0 turbo 4-cylinder.

As tested in Car and Driver the Genesis GV70 is faster than the Mercedes GLB:

The GV70 has 1.5 gallons more fuel capacity than the GLB (17.4 vs. 15.9 gallons), for longer range between fill-ups.

The GV70’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The GLB doesn’t offer launch control.

For better stopping power the GV70’s brake rotors are larger than those on the GLB:

The GV70’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the GLB are solid, not vented.

For better traction, the GV70 Sport’s optional tires are larger than the largest tires available on the GLB (255/40R21 vs. 235/55R18).

The GV70 Sport’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the GLB’s optional 45 series tires.

For better ride, handling and brake cooling the GV70 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLB. The GV70 Sport’s optional 21-inch wheels are larger than the 20-inch wheels optional on the GLB.

The GV70 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLB; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLB don’t have a run-flat feature, either.

For a smoother ride and more stable handling, the GV70’s wheelbase is 1.8 inches longer than on the GLB (113.2 inches vs. 111.4 inches).

For better handling and stability, the average track (width between the wheels) on the GV70 is 1.6 inches wider in the front and 2.3 inches wider in the rear than the track on the GLB.

The GV70’s front to rear weight distribution is more even (52.6% to 47.4%) than the GLB’s (57% to 43%). This gives the GV70 more stable handling and braking.

The GV70 Sport Prestige executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the GLB 250 4MATIC (26.4 seconds @ .7 average G’s vs. 27.5 seconds @ .63 average G’s).

For better maneuverability, the GV70’s turning circle is .7 feet tighter than the GLB’s (37.7 feet vs. 38.4 feet).

The GV70 has .2 inches more front legroom, 3.2 inches more front shoulder room and 2 inches more rear shoulder room than the GLB.

The GV70 has a much larger cargo volume than the GLB with its rear seat up (28.9 vs. 5.1 cubic feet).

The GV70’s cargo area is larger than the GLB’s in almost every dimension:

Pulling a handle automatically lowers the GV70’s rear seats, to make changing between passengers and cargo easier. The GLB doesn’t offer automatic folding seats.

The GV70 has a 3500 lbs. towing capacity. The GLB has no towing capacity.

The engine in the GV70 is mounted longitudinally (North-South), instead of sideways, as in the GLB. This makes it easier to service and maintain, because the accessory belts are in front.

The GV70 3.5T Sport Prestige has a standard 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 GLB doesn’t offer a heads-up display.

To improve rear visibility by keeping the rear window clear, the GV70 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLB only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the GV70’s headlight performance “Good,” a higher rating than the GLB’s headlights, which were rated “Fair.”

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the GV70 has standard extendable sun visors. The GLB doesn’t offer extendable visors.

Manual rear side window sunshades are available in the GV70 to help block heat and glare for the rear passengers. The GLB doesn’t offer rear side window sunshades.

The GV70 has standard heated front seats. Heated front seats cost extra on the GLB. The GV70 3.5T Sport Prestige also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Genesis GV70 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the GLB.

The GV70 Sport Advanced/Sport Prestige’s Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GLB’s automatic parking system does not offer parking by remote control.
