Mercedes-Benz is adding four new models to its lineup this summer – well, kind of. Replacing the GLK and ML, the GLC and GLE plus “coupe” variants of each are poised to take the fight to Audi and BMW in this hotly contested luxury SUV market.

The drivetrain options are numerous, but the big news is an upcoming plug-in hybrid version of the GLE and a new nine-speed gearbox. With an ambitious three-pronged attack based on sport, style and comfort, the revised Mercedes-Benz SUV lineup is bringing some big changes.
