2023 Mercedes-Benz GLA vs 2023 Mercedes-Benz GLB

Serving Milwaukee, WI

The 2023 Mercedes-Benz GLA and its close sibling, the GLB, are smaller crossovers that produce the powerful, premium driving experience that today’s drivers crave. While these exciting options are comparable in several ways and sit next to each other in the 2023 lineup, they are unique in critical areas. We are eager to support you at Mercedes-Benz of Milwaukee North as you get better acquainted with these models.


You will undoubtedly be thrilled by the performances of these Mercedes-Benz crossovers thanks to their powerful engines and great mechanical features. The GLA 250 for 2023 has a four-cylinder, 2.0-liter turbo, 221-horsepower engine. It is offered with an eight-speed, dual-clutch automatic transmission and available 4MATIC® all-wheel drive. The other GLA trims are equipped with standard 4MATIC® all-wheel drive. The mid-level trim, the AMG® GLA 35, has a turbocharged 2.0-liter, four-cylinder, 302-horsepower system, and the AMG® GLA 45 is equipped with a high-performance, 382-horsepower variation of the same powertrain. If you choose an AMG® GLA model, your crossover will also have upgraded braking, an enhanced exhaust system, and a few driving modes.

In comparison, the GLB 250 and GLB 250 4MATIC® trims have the same 221-horsepower engine and the same transmission that are available in the GLA. Likewise, the AMG® GLB 35 is outfitted with the same 302-horsepower system that the AMG® GLA 35 has. The AMG® GLA 35 includes additional driving modes, improved braking functionality, and a sport exhaust.


The 2023 Mercedes-Benz GLA and GLB are easy to tell apart in a side-by-side comparison. The two-row GLA has an arched roof with a sharp angle through the hood. The sides are dressed up with modest molding and horizontal contours. The grille has a vertical-bar design on the GLA’s nose, and horizontal elements cross through the bumper. The LED-enhanced headlamps complete the look. Comparatively, the 2023 Mercedes-Benz GLB is a boxier crossover with a fairly level roof. This ensures that passengers in the optional third row have ample space for comfort. While the GLB has smooth contours on its sides, they are accompanied by prominent door molding. Other differences include the GLB’s rectangular headlights, the sectioned bumper, and the more prominent grille. These models are both available with rain-sensing wipers, auto-dimming and power-folding side mirrors, hands-free entry, a hands-free liftgate, and a sunroof.


Thanks to their shared features, you will feel pampered while driving the GLA and the GLB. Some of the equipment offered in both models for select or all trims include a traffic sign reader, augmented reality with the navigation system, adaptive cruise control, ambient cabin lighting, blind-spot monitoring, Android Auto, Apple CarPlay, forward collision mitigation, Mercedes Me, an MBUX infotainment system, a two-zone auto climate management system, driver’s memory functions, heated seats, and simulated leather upholstery. There are a few features that are only available in the GLB. These include a surround-view camera, automated parking, a household power outlet, USB-C ports, a touch controller pad, reclining rear seats, and voice recognition.
