The car was built on the front-wheel-drive MFA platform. The same chassis is used by the Mercedes A-Class and GLA. The wheelbase of the new model is 12.7 cm longer than the GLA and 4.3 cm shorter than the GLC.
The new model features three rows of seats and seven seating positions. The second row can be folded in a 40:20:40 ratio. The third row of seats has cup holders, USB ports, side airbags, and child seat anchors. The five-seat version of the GLB turned out to be more spacious - for example, the trunk volume with the rear seats folded is 1755 liters.
The crossover also received a digital instrument cluster, a 7.0-inch touchscreen display, and the MBUX multimedia system that debuted on the fourth-generation A-Class family. The system can recognize voice commands, understanding "natural" language, and some functions can be controlled with gestures. For an additional cost, drivers are offered a 10.25-inch display and a Burmester audio system.
The base versions of the GLB will go on sale with front-wheel drive. Customers will also be offered the 4Matic all-wheel-drive system. Under normal conditions, torque is transmitted to the front wheels, but if necessary, traction can be distributed between the axles in a 50:50 ratio.
So far, the car has been presented only with the top-end 2.0-liter four-cylinder turbocharged gasoline engine. The unit's power is 224 hp and 350 Nm of torque. With this engine, the car accelerates to 100 km/h in 6.9 seconds. The unit works in conjunction with an eight-speed gearbox. The power of the other units should be from 150 to 190 horsepower. The GLB also received air suspension and adaptive dampers.
