Compare the2023 Volkswagen AtlasVS 2023 Mercedes GLB

The Atlas has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLB doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Atlas offers optional Maneuver Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.

Both the Atlas and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, lane departure warning systems and 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, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Atlas its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 134 vehicles tested by the IIHS. The GLB has not been tested, yet.

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

Volkswagen pays for scheduled maintenance on the Atlas for 2 years and 20,000 miles. Volkswagen will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLB.

There are over 66 percent more Volkswagen dealers than there are Mercedes dealers, which makes it much easier should you ever need service under the Atlas’ warranty.

The Volkswagen Atlas’ engines use a cast iron block for durability, while the GLB’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The Atlas 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 Atlas’ wheelbase is 5.9 inches longer than on the GLB (117.3 inches vs. 111.4 inches).
