2026 Mercedes-Benz GLB vs the Competition

BMW’s X2 and X1 models emulate the GLA / GLB relationship, with the former representing a fastback roof variant of the latter, both classified within the luxury sub-compact crossover segment. The X1 is sufficiently compact to share its front-drive-based platform with the Mini Countryman, although it is equipped as standard with all-wheel drive (AWD). Like the GLB, it is powered by a 2.0-liter turbocharged inline-4 engine with two different tuning options. The X2 M28i delivers 241 horsepower and 295 lb-ft of torque, while the M35i maintains the same peak torque but elevates horsepower to 312. Power is transmitted via a 7-speed dual-clutch automatic transmission. The primary focus of this model is performance, which may come at the expense of ride comfort. 

• The X1 7-speed dual-clutch transmission tends to be rough at low speeds, causing slight lurching and sluggish throttle response from a stop. This can be particularly frustrating in stop-and-go traffic.
• For its size, the GLB has a surprisingly long 111.4-inch wheelbase, which helps provide a comfortable, stable highway ride. The X1 is significantly shorter at 106 inches.
• Rear seat passengers will enjoy the additional inch of legroom in the GLB (38.1 vs. 37.0 inches).
• The X1 does not offer an optional third-row seat.
• The GLB comes standard with a hands-free power liftgate, a feature not available on the X1.
• The GLB comes standard with parallel and perpendicular automated parking. The X1 does not have this feature.
• The GLB and X1 trade cargo space advantages. With the rear seats up, the X1 has the advantage (22.0 vs. 25.7 cubic feet), while the GLB has the advantage in maximum cargo capacity (62.0 vs. 57.2 cubic feet).

The Audi Q3 was introduced in the 2012 model year and is currently the smallest model in the Audi lineup in the United States. The current iteration is the third design generation, launched for the 2026 model year. Like many vehicles in this category, it is equipped with a 2.0-liter turbocharged inline-4 engine that produces 255 horsepower and 273 lb-ft of torque. Power is delivered through a 7-speed dual-clutch transmission and distributed to all four wheels via the Quattro all-wheel-drive system. The Q3 shares its platform with the Volkswagen Tiguan but is smaller overall.

• The Q3 comes with a 7-speed dual-clutch transmission that shifts rapidly for sporty driving but can feel a bit rough at low speeds, resulting in slight jerks and slower throttle response from a complete stop. This may be especially annoying in stop-and-go traffic.
• The GLB 4MATIC® has noticeably better EPA-estimated city/highway/combined mpg than the Q3 (24/33/27 vs, 22/29/25).
• The GLB has a much longer wheelbase than the Q3 to help provide a comfortable, stable highway ride (111.4 vs. 105.6 inches).
• The Q3 is not available with a 3rd row seat.
• The GLB comes standard with a hands-free power liftgate, which is not available on the Q3.
• The GLB comes standard with automated parallel and perpendicular parking; a feature not available on the Q3.
• The GLB has more space than the Q3 in several metrics, including front headroom: (40.7 inches vs. 38.1), rear headroom (39.3 inches vs. 37.6), front legroom (41.4 inches vs. 40.0), and rear legroom (38.1 inches vs. 36.1).
• The GLB also has 24% more maximum cargo space than the Q3 (62.0 cubic feet vs. 50.0).
• Mercedes-Benz has a better showing in the 2026 J.D. Power Initial Quality Study with 182 problems per 100 vehicles compared to the 225 problems per 100 vehicles for Audi.
• According to Kelley Blue Book, the GLB loses about 45.6% of its value after five years compared to Q3, which loses about 50.3% of its value.

The XC40 is Volvo’s smallest crossover. Like the rest of the Volvo lineup, it features a distinctly Scandinavian interior design and plenty of Volvo design cues on the exterior. The plug-in hybrid and EV versions are no longer available in the XC40 lineup, with the hybrid discontinued and the EV adopting a different model name to align with the brand’s EV nomenclature.

The remaining XC40 is powered by a 2.0-liter turbocharged inline-4 in two states of tune. One produces 194 horsepower and 221 lb-ft of torque, while the other bumps up to 247 horsepower and 258 lb-ft of torque. Both have a mild hybrid component that assists with initial start-up and acceleration. The engines are paired with an 8-speed transmission, and FWD is standard while AWD is available. The XC40 is available in Core, Plus, and Ultra trims.

• The GLB’s base powertrain is noticeably more powerful than the XC40’s in both horsepower (221 vs. 194) and torque (258 lb-ft vs. 221). In fact, the GLB’s torque matches that of the XC40’s more expensive engine option.
• Though more powerful, the GLB with the base engine and FWD gets slightly better fuel economy than the comparable XC40 (25/33/28 MPG city/ highway/ combined vs. 25/32/27).
• The AMG® GLB 35 drivetrain is more powerful than the XC40’s most powerful engine, with both higher horsepower (302 vs. 247) and torque (295 vs. 258 lb-ft).
• The GLB’s 111.4-inch wheelbase is significantly longer than the XC40’s 106.4-inch wheelbase, helping provide a comfortable, stable highway ride. 
• The base GLB comes standard with automated parallel and perpendicular parking and remote engine start, two features not available on the price-comparable XC40 Core trim.
• The XC40 is not available with a third row seat.
• The GLB has more space than the XC40 across several metrics, including: 
  • Front headroom: (40.7 inches vs. 37.6)
  • Rear headroom: (39.3 inches vs. 38.3)
  • Front legroom: (41.4 inches vs. 40.9)
  • Rear legroom: (38.1 inches vs. 36.1)
• The GLB offers more cargo space, both with the rear seats up (22.0 cubic feet vs. 20.1) and when the rear seatbacks are folded (62.0 cubic feet vs. 57.5).
• Mercedes-Benz has a better showing in the 2026 J.D. Power Initial Quality Study, with 182 problems per 100 vehicles, compared with Volvo’s 221 problems per 100 vehicles.

Lexus’s smallest NX shares its platform with the Toyota RAV4 but did not receive a redesign in 2026 like its corporate sibling. The NX does not overtly share any exterior or interior design with the RAV4, instead featuring Lexus’s distinctive (albeit possibly polarizing) front grille on an otherwise chiseled body, though with a much higher beltline and shorter windows than the GLB. The NX ranks among the most powerful models in this comparison, with its 2.4-liter turbocharged inline-4 engine delivering 275 horsepower and 317 lb-ft of torque.

The NX is also offered with a hybrid drivetrain based on a non-turbocharged 2.5-liter engine producing 240 horsepower, and a plug-in hybrid ($59,505) that generates 304 horsepower and provides an estimated 37 miles of electric vehicle (EV) range. Notably, the hybrid variant is available with both front-wheel drive (FWD) and all-wheel drive (AWD), whereas the non-hybrid model comes with standard AWD.

• Although the NX engine is more powerful, MotorTrend tested the NX 350 and a GLB, both with AWD and found the GLB quicker in 0-60 mph (6.2 seconds vs. 7.3 ) and in the quarter mile (14.8 seconds vs. 15.5).
• The GLB with AWD has a better EPA estimate. mpg rating than the standard AWD NX (24/33/27 MPG city/ highway/ combined vs. 21/28/24).
• The GLB has more space than the NX across several metrics, including (all figures in inches):
  • Front headroom: (40.7 inches vs. 38.3)
  • Rear headroom: (39.3 inches vs. 38.5)
  • Front legroom: (41.4 inches vs. 41.0)
  • Rear legroom: (38.1 inches vs. 36.1)
• The GLB also has 32% more maximum cargo space than the NX (62.0 cubic feet vs. 46.9).
• The GLB has standard driver position memory, a feature that requires an upgrade on the NX.
• A hands-free power liftgate is standard on the GLB. The NX has a power tailgate but not a hands-free system without an upgrade in trims.
• The GLB offers the additional flexibility of a 40/20/40 split-folding rear seatback, giving you more loading options than the NX’s 60/40 split seatbacks.
• The NX is not available with a 3rd-row seat.
• The GLB has a class-leading 111.4-inch wheelbase, which helps provide a comfortable, stable highway ride. The NX wheelbase is significantly shorter at 105.9 inches.
