The 2026 Mercedes-Benz GLB differentiates itself from the related GLA with boxier styling and a more traditional SUV vibe, albeit in a smaller package. It competes with small luxury SUVs such as the BMW X1, the Audi Q3, and the Volvo XC40.

What’s New for the 2026 Mercedes-Benz GLB
First launched for the 2020 model year, the GLB preps for a new iteration for the 2027 model year. For now, the 2026 GLB can be had with cosmetic upgrades shared with its GLA sibling. For no extra cost, shoppers can opt for an AMG Line Lite to get 19-inch AMG wheels and a rear spoiler. A $1,950 Midnight Edition takes parts from the brand’s performance arm with adaptive dampers, 20-inch AMG wheels, and black exterior accents. A $1,500 Sun and Sound package bundles a panoramic sunroof and a 10-speaker sound system.
The actual AMG GLB has a new Design Package Plus with Alpine Grey paint and the gloss-black accents of the Night Package Plus. It rolls on 19-inch AMG wheels and has red AMG brake calipers.
Design
The GLB SUV is the more upright, boxy counter to the related GLA. It’s the dog to the GLA’s cat in Mercedes' growing SUV family. The small crossover has aged well with understated elegance. Horizontal bars hold up the big Mercedes badge in the grille, and relatively large headlights sit over large fog light housings. Opting for the Night Package adds large 20-inch black alloy wheels and a flashier grille, as well as black accents that give this bulldog a sinister allure. The interior acts young and hip with various ambient lighting options and twin 10.3-inch displays under a single pane of glass detracting attention from classic Mercedes design elements, such as circular vents and available wood and aluminum trim. The nightlife vibe also conceals some cheaper plastic parts on the doors and lower dash that reveal its entry-level nature, even with the Tri-Star’s pedigree.
Powertrain
Every 2026 GLB has a 48-volt mild-hybrid system to assist the 2.0-liter turbocharged four-cylinder engine off the line. The base GLB 250’s engine makes 221 horsepower and a potent 258 pound-feet of torque. It’s quick enough at speed, but its off-the-line drags its zero-to-60-mph time to 6.9 seconds. A standard eight-speed dual-clutch automatic transmission (DCT) shifts quickly, and the four drive modes delay or hasten the shifts to provide more power or for greater efficiency. Front-wheel drive (FWD) is standard, while all-wheel drive (AWD) is a $2,000 option.
For more spirited performance, step up to the AMG GLB 35 with a standard AWD system with more of a rear bias. The engine is tuned to 302 hp and 295 lb-ft, good for a zero-to-60-mph time of 5.4 seconds, according to Mercedes. That’s 0.3 seconds off the sleeker AMG GLA 35.
The mild-hybrid system also helps with fuel economy. The GLB 250 has an EPA estimate of 25 mpg city, 33 highway, and 28 combined. That’s 1 mpg off the GLA. Adding 4Matic AWD doesn’t hurt efficiency much, with a rating of 24 mpg city, 33 highway, and 27 combined. The AMG GLA 35 returns 21 mpg city, 27 highway, and 23 combined.
Interior
The GLB tries to go big with its small space by offering a third row for $850, but fitting even two small bodies back there requires wiggle room for all five rear passengers. There’s only 29.1 inches of legroom in the way back, and headroom shrinks to 34.8 inches, which means it can’t accommodate anyone older than grade schoolers. The starting peewee basketball team might need to keep their bags in their laps, as there’s only 12.4 cubic feet of cargo space.
Without the third-row seats, the second row has decent legroom (38.4 inches) and headroom (39.3 inches). The 40/20/40-split seats fold down to expand the cargo space to up to 62 cubic feet, and that configuration keeps the small SUV versatile enough to load four passengers and their gear for a comfy weekend getaway.
Standard features across the lineup include 18-inch wheels, synthetic leather upholstery, remote start, dual-zone automatic climate control, four USB ports, power-adjustable front seats, and sliding and reclining rear seats.
Opting for the $1,600 Exclusive trim adds keyless start, 64-way ambient lighting, wireless device charging, active park assist, and biometric authentication that uses fingerprint, voice, or facial recognition to activate driver profiles and other stored info.
The $5,450 Pinnacle trim includes those features and adds a panoramic sunroof, dynamic LED headlights, navigation, a head-up display, a surround-view camera system, and other interior lighting elements.
The AMG GLA 35 comes with 19-inch wheels, heated front seats, a power liftgate, 64-way ambient lighting, and sport front seats with more bolstering.
Technology
Also standard across the lineup are dual 10.25-inch displays under a single pane of glass. The steering wheel sliders can be finicky while driving to toggle through vehicle info and display options in the digital instrument cluster. The touchscreen portion curves toward the driver for easier ergonomics, and it includes wireless Apple CarPlay and Android Auto.
The latest iteration of the MBUX infotainment system has good responsiveness to “Hey, Mercedes…” voice prompts so you can keep your hands on the wheel.
