Price: The GLB Leads
At $43,800, the GLB 250 starts thousands below the X3 and Q5. Even with 4MATIC® all-wheel drive at $45,800, it leaves room in the budget for options like the third row or premium audio.
Want more performance? The AMG® GLB 35 4MATIC® delivers 302 hp and a 0 to 60 mph time of 5.4 seconds, starting at $60,600.
Space: The Only One With a Third Row
The GLB is the only SUV in this group that offers a third row, bringing seating to seven. It's ideal for carpools, soccer practice or visiting family. Its boxy shape also pays off in headroom and a practical, square cargo area.
The X3 and Q5 seat five and focus on a sportier driving feel.
Technology and Comfort
The GLB features MBUX infotainment with widescreen digital displays, natural voice control and wireless smartphone integration, plus 64-color ambient lighting. BMW's iDrive and Audi's MMI systems are also well designed, so try each to see which you prefer.
