Mercedes-Benz is debuting a new member of its compact SUV family this summer. The so-called GLB will share its bones with the A-Class, and based on spy photos, we know will have a boxy, upright shape. We still don't know what will power it, but our best guess is the A-Class Sedan's turbo 2.0-liter producing 188 horsepower (140 kilowatts) and 221 pound-feet (299 Newton-meters) of torque.
