2021 GLB-Class trim level differences

The 2021 Mercedes-Benz GLB is a small, entry-level luxury SUV with seating for five. An optional third-row of seats expands capacity for two more (very small) passengers. The GLB comes in three trim levels: GLB 250, GLB 250 4Matic and AMG GLB 35.

The GLB 250 and GLB 250 4Matic are powered by a turbocharged 2.0-liter four-cylinder engine (221 horsepower, 258 lb-ft of torque) connected to an eight-speed automatic transmission. The GLB 250 is front-wheel-drive, while all-wheel drive comes standard on the 4Matic. The AMG GLB 35 uses a high-performance version of the same engine (302 hp, 295 lb-ft of torque) and eight-speed transmission. All-wheel drive comes standard.

GLB 250 and GLB 250 4Matic
The base trim GLB comes nicely equipped with standard features including:

  • LED headlights
  • Power liftgate
  • 18-inch wheels
  • Aluminum roof rails
  • Heated side mirrors
  • Rain-sensing windshield wipers
  • Push-start ignition

Interior features include:

  • Dual-zone climate control
  • Simulated leather upholstery
  • Power-adjustable front seats with memory settings
  • Sliding and reclining rear seats
  • Household-style power outlet

Standard technology and safety features include:

  • 7-inch touchscreen display
  • Touchpad controller
  • Digital gauge cluster display
  • Mercedes' MBUX infotainment interface
  • Apple CarPlay and Android Auto smartphone integration
  • Four USB-C ports
  • Blind-spot monitor (warns you if a vehicle is in your blind spot during a lane change or while reversing)
  • Forward collision warning with automatic emergency braking (warns if a front impact is imminent and applies the brakes if you don't respond in time)

AMG GLB 35
In addition to a more powerful engine and all-wheel drive, the new AMG GLB 35 adds:

  • 19-inch wheels
  • Aluminum and brushed steel interior trim
  • 10.25-inch infotainment display
  • Bigger driver information display
  • Customizable ambient cabin lighting

The GLB 250 and AMG GLB 35 offer abundant options, both à la carte and bundled in packages. Highlights include:

  • Driver Assistance package
    • Adaptive cruise control (maintains a driver-set distance between the GLB and the car in front
    • Lane keeping assist (steers the GLB back into its lane if it begins to drift over the lane marker)
    • Lane keeping system (makes minor steering corrections to help keep the vehicle centered in its lane)
    • Enhanced blind-spot monitoring (can steer the GLB to help avoid a collision with a vehicle in your blind spot)
  • Panoramic sunroof
  • Adaptive sport suspension
  • Third-row seats
  • Leather upholstery
  • Heated and ventilated front seats
  • Heated steering wheel
  • Touch door lock/unlock
  • Navigation system
  • Upgraded Burmester sound system
  • Wireless charging pad

Which 2021 GLB-Class trim does Edmunds recommend?

For many drivers, the base GLB 250 (or its 4Matic all-wheel-drive counterpart for slick-weather regions) is a fine choice. But for those of a sporting persuasion, we'd recommend the AMG GLB 35 for its 302-horsepower engine and performance-tuned suspension. It demands a significant price jump but transforms the GLB into a small SUV hot rod.
