The little GLB from Mercedes-Benz isn't as compact as you might think. In fact, its interior can accommodate up to seven passengers across three rows. Needless to say, those sitting all the way back don’t enjoy the type of comfort Mercedes-Benz is known for. As for powertrain selection, the standard turbocharged four-cylinder engine develops 221 hp, while the one powering the AMG 35 model increases output to 302 hp. Both feature mild hybrid technology to improve efficiency.
