Mercedes-Benz GLB: Price, Specs, Features & Review
The Mercedes-Benz GLB is a compact luxury SUV with a practical advantage that many rivals do not offer: an available third row. It has a boxier shape than the smaller GLA, more usable cargo space, and a cabin that can be configured for five or seven passengers.
The standard GLB 250 is designed for daily driving, with a turbocharged mild-hybrid engine, a roomy second row, and enough performance for normal commuting and highway travel. The GLB 250 4MATIC adds all-wheel drive, while the Mercedes-AMG GLB 35 brings much quicker acceleration and a more performance-focused setup.
The optional third row is best viewed as occasional seating for children or smaller passengers. Buyers who regularly need to carry seven adults should move up to a larger three-row SUV.
WheelPedia Rating: 8.1/10
The Mercedes-Benz GLB earns an 8.1/10 WheelPedia Rating for its flexible interior, available third row, strong standard technology, efficient turbocharged engine, and compact exterior dimensions.
Its main drawbacks are a high starting price, a tight third row, premium-fuel requirement, and long-term ownership costs that are higher than those of mainstream compact SUVs.

Expert Tip
The GLB 250 4MATIC is the best fit for most families in four-season climates. Its added traction is useful, while the GLB’s real reason to buy remains its flexible cabin—not its off-road capability.
About the Mercedes-Benz GLB
The GLB occupies a useful position in the Mercedes-Benz SUV range. It is larger and more upright than the Mercedes-Benz GLA, but it is easier to park and less expensive than a larger GLC, GLE, or GLS.
Its square-shaped body gives it a more practical cabin than the GLA. The GLB can carry more cargo, offers a more family-friendly second row, and is available with a small third row. Those qualities make it one of the few luxury compact SUVs that can serve as a part-time seven-passenger vehicle.
The GLB 250 is the mainstream version. The AMG GLB 35 is considerably faster and sharper to drive, but its stronger performance comes with a higher purchase price, firmer ride, and greater fuel and maintenance costs.
Price and Trims
These are current U.S. starting MSRPs. Final prices can change with destination charges, paint, wheel choices, option packages, dealer-installed accessories, and local market conditions.
| Trim | Starting MSRP | Powertrain | Drivetrain | 0–60 mph |
| GLB 250 SUV | $43,800 | 221-hp 2.0L turbo mild hybrid | FWD | 6.9 sec |
| GLB 250 4MATIC SUV | $45,800 | 221-hp 2.0L turbo mild hybrid | AWD | 6.9 sec |
| Mercedes-AMG GLB 35 SUV | $60,600 | 302-hp 2.0L turbo mild hybrid | AWD | 5.4 sec |
The front-wheel-drive GLB 250 is the right choice if budget and fuel economy are your top priorities. It has the same interior layout and available third row as the 4MATIC model.
The GLB 250 4MATIC is worth the additional cost for buyers who deal with rain, snow, steep driveways, or unpaved access roads. It is the strongest all-round choice for most people shopping this range.
The AMG GLB 35 is for drivers who want a genuinely quick compact SUV. It does not make the third row larger or improve the GLB’s family usefulness, so its value depends on how much you care about performance.
Engine, Powertrain, and Performance
The GLB 250 uses a turbocharged 2.0-liter four-cylinder engine with a 48-volt mild-hybrid system. It produces 221 horsepower and 258 lb-ft of torque and sends power through an 8-speed dual-clutch automatic transmission.
The mild-hybrid system supports smoother stop-start operation and can provide brief electric assistance during acceleration. It is not a full hybrid system and does not allow electric-only driving.
| Model | Engine | Horsepower | Torque | Drivetrain |
| GLB 250 | 2.0L turbo mild hybrid | 221 hp | 258 lb-ft | FWD |
| GLB 250 4MATIC | 2.0L turbo mild hybrid | 221 hp | 258 lb-ft | AWD |
| AMG GLB 35 | AMG-enhanced 2.0L turbo mild hybrid | 302 hp | 295 lb-ft | AWD |
The GLB 250 has enough power for normal family use. It accelerates confidently in city traffic and has adequate passing power at highway speeds, though it does not feel especially quick when heavily loaded with passengers and luggage.
The AMG GLB 35 uses a more powerful engine, AMG-tuned 8-speed dual-clutch transmission, all-wheel drive, adaptive damping, and stronger brakes. It is much more responsive than the standard GLB, but it is not the trim to choose if comfort and low running costs matter most.
0–60 MPH Performance
| Model | Manufacturer-Claimed 0–60 mph Time |
| GLB 250 SUV | 6.9 sec |
| GLB 250 4MATIC SUV | 6.9 sec |
| Mercedes-AMG GLB 35 SUV | 5.4 sec |
The standard GLB is quick enough for commuting, school runs, and highway travel. The AMG GLB 35 is more than a second quicker to 60 mph and feels substantially stronger in passing situations.
Driving Experience
The GLB is more upright and practical than the smaller GLA. Its driving position gives the driver a clear view forward, and its compact footprint helps it remain easy to handle in city traffic and parking garages.
The standard suspension is tuned more for comfort than sport. It handles daily driving well, although rough pavement is more noticeable with larger optional wheels. The dual-clutch transmission can feel less smooth at low speeds than a conventional automatic, especially during stop-and-go traffic or parking maneuvers.
The GLB 250 4MATIC adds confidence on slippery roads by sending power to the rear wheels when needed. It is useful for poor weather, but buyers should still use winter tires where winter conditions are severe.
The AMG GLB 35 has much quicker steering and stronger braking, but it rides more firmly. It is engaging for a compact SUV, yet the standard GLB 250 is the better fit for buyers who prioritize passenger comfort.
Fuel Economy
| Model | City | Highway | Combined |
| GLB 250 SUV | 25 mpg | 33 mpg | 28 mpg |
| GLB 250 4MATIC SUV | 24 mpg | 33 mpg | 27 mpg |
| Mercedes-AMG GLB 35 SUV | 21 mpg | 27 mpg | 23 mpg |
The front-wheel-drive GLB 250 is the most efficient version. Its fuel economy is reasonable for a premium compact SUV with this much passenger and cargo flexibility, but premium unleaded gasoline is required.
The 4MATIC model gives up only a small amount of fuel economy for all-wheel drive. The AMG GLB 35 uses more fuel because of its higher-output engine, all-wheel-drive system, and performance tuning.
Real-world fuel economy can vary with driving style, weather, traffic, passenger load, wheel choice, and use of air conditioning or heating.
Interior, Comfort, and Technology
The GLB cabin is functional, well finished, and more family-oriented than its smaller GLA sibling. Its upright roofline gives the first and second rows a more open feel, while the available third row provides occasional extra seating.
Standard and available features include:
- Dual 10.25-inch digital displays
- MBUX infotainment system
- “Hey, Mercedes” voice assistant
- Wireless Apple CarPlay
- Wireless Android Auto
- Power front seats with memory
- Dual-zone automatic climate control
- Sliding and reclining second-row seats
- Power liftgate
- Available third-row seating
- Available panoramic roof
- Available wireless charging
- Available 64-color ambient lighting
- Available Burmester surround-sound system
- Available head-up display
- Available navigation with augmented-reality guidance
The front seats are comfortable and supportive. The second row is one of the GLB’s better features: it is more accommodating than the GLA’s and can slide forward to free up room for third-row passengers.
The optional third row is useful for children, short trips, or occasional extra passengers. With only 29.1 inches of third-row legroom, it is not a comfortable long-distance space for most adults.
Dimensions, Cargo, and Practicality
| Dimension | Measurement |
| Length | 182.4 in. |
| Width without mirrors | 72.2 in. |
| Width with mirrors | 79.5 in. |
| Height | 66.7 in. |
| Wheelbase | 111.4 in. |
| Front headroom | 40.7 in. |
| Second-row headroom | 39.3 in. |
| Third-row headroom | 34.8 in. |
| Front legroom | 41.1 in. |
| Second-row legroom | 38.1 in. |
| Third-row legroom | 29.1 in. |
| Cargo capacity | 12.4–62.0 cu. ft. |
| Seating capacity | 5 standard; 7 optional |
Cargo capacity changes significantly with the seating layout. The 12.4-cubic-foot minimum applies when the optional third row is in use. Folding the rear seats opens up a maximum of 62.0 cubic feet for larger items.
The GLB is a strong option for buyers who need flexibility more than maximum passenger space. It can handle errands, sports equipment, strollers, and weekend luggage well, but a fully occupied seven-seat GLB leaves limited room for cargo.
Exterior Design
The GLB has a boxy, upright design that clearly favors practicality. It is less coupe-like than the GLA, with a taller roof, squared-off rear end, and a more traditional SUV profile.
Standard models use a clean, understated appearance with LED lighting and 18-inch wheels. Available packages can add AMG-inspired styling, larger wheels, darker exterior trim, and sportier design details.
The AMG GLB 35 adds a more aggressive grille, AMG-specific wheels, larger brakes, and performance styling. It has a more assertive look than the standard GLB without changing the basic practical shape.
Safety Features and Ratings
Standard and available safety features include:
- Active Brake Assist
- Blind Spot Assist with Exit Warning Assist
- ATTENTION ASSIST driver monitoring
- Rearview camera
- LED headlamps
- PRE-SAFE occupant protection system
- Available DISTRONIC adaptive cruise control
- Available Active Steering Assist
- Available Active Lane Keeping Assist
- Available Active Lane Change Assist
- Available surround-view camera system
- Available Active Parking Assist
The GLB’s standard safety equipment covers important daily risks, particularly automatic emergency braking and blind-spot monitoring. Several advanced assistance features are optional, so check the exact vehicle and package list before buying.
The IIHS gives the 2025 GLB an Acceptable rating for whiplash prevention. It does not appear among the current 2026 IIHS award winners, so buyers should not assume a current Top Safety Pick designation. Check the latest IIHS GLB ratings for the specific model year and test coverage.
Reliability, Warranty, and Ownership
The GLB is a technology-heavy luxury SUV with a turbocharged engine, mild-hybrid electrical system, and dual-clutch transmission. Proper maintenance is important, and service or repair costs will generally be higher than for a mainstream compact SUV.
The GLB 250 is the lower-cost ownership choice. The AMG GLB 35 adds more specialized mechanical parts, performance tires, larger brakes, and higher insurance costs, so it needs a larger long-term budget.
| Coverage | Length |
| New Vehicle Limited Warranty | 4 years / 50,000 miles |
| Roadside Assistance | 4 years / 50,000 miles |
| Federal Emissions Warranty | Up to 8 years / 80,000 miles on selected components |
Before buying a used GLB, review its full service history, tire condition, brake wear, wheel damage, electronic functions, third-row operation if fitted, and open recall status. A Mercedes-Benz Certified Pre-Owned vehicle can be useful for buyers who want coverage beyond the original warranty.

Should You Buy the Mercedes-Benz GLB?
Buy the Mercedes-Benz GLB if you want a premium compact SUV with more passenger and cargo flexibility than most alternatives. It is particularly well suited to small families that need an occasional third row but do not want the size of a midsize SUV.
Choose the GLB 250 SUV if you want the lowest price and mainly drive on dry roads. Choose the GLB 250 4MATIC if you want the best overall balance of all-weather ability, family usefulness, and ownership costs.
Choose the AMG GLB 35 only if stronger performance matters enough to justify the higher price, firmer ride, fuel use, insurance, and maintenance costs.
Skip the GLB if you need a genuinely adult-friendly third row, a large cargo area with all seats occupied, regular-grade fuel, or lower-cost long-term ownership.

Final Verdict
The Mercedes-Benz GLB is one of the most practical small luxury SUVs. Its compact exterior dimensions, spacious second row, optional third row, and flexible cargo area make it a strong choice for buyers who need more utility than the smaller GLA can provide.
The GLB 250 4MATIC is the sweet spot. It gives most families the traction they want, preserves the GLB’s useful interior layout, and avoids the much higher price and ownership costs of the AMG GLB 35.
The central compromise is the third row: it is useful, but it is not a substitute for a full-size seven-passenger SUV. For buyers who need occasional extra seats and prefer a premium compact vehicle, the GLB is a very sensible option.
Prices, specifications, fuel-economy ratings, safety results, and feature availability can change by trim, model year, and market.
