The Mercedes-Benz GLC is a compact luxury crossover SUV introduced in 2015 for the 2016 model year that replaced the GLK-Class. According to Mercedes-Benz, it is the SUV equivalent to the C-Class.

Under the vehicle naming scheme maintained by Mercedes-Benz, SUVs use the base name "GL", followed by the model's placement in Mercedes-Benz hierarchy. The "G" is for Geländewagen (German for off-road vehicle) and alludes to the long-running G-Class. This is followed by the letter "L" that acts as a linkage with the letter "C" to signify that the vehicle is a SUV equivalent to the C-Class.

First generation (X253/C253; 2015)

Like its predecessor, it is assembled at Mercedes-Benz's plant in Bremen, Germany. Since the main GLC production site in Bremen already runs at full capacity, Mercedes-Benz have decided to expand the production capacity by utilizing Valmet Automotive plant at Uusikaupunki, Finland. The manufacturing of the GLC started in Finland during Q1 of 2017.

The first-generation GLC was available in a five-door body style with seating for five. Mercedes also offers a GLC Coupé, with a sloping rear roof design. In mainland Europe, it is available with three diesel engines, three petrol engines, and a plug-in hybrid. In the United Kingdom, only three diesels and one petrol AMG-model are offered.

Power comes from a choice of 2.0-litre 4-cylinder turbocharged petrol (same engine combined with the electric engine in the 350e hybrid) and 2.2-liter 4-cylinder turbo diesel engines in various power stages mated to a 9-speed (7-speed for the 350e hybrid) G-Tronic automatic transmission. 4MATIC all-wheel-drive is standard in some markets and optional in others. The GLC has a track width of 63.9 in (1,623 mm) in front and 63.7 in (1,618 mm) in the rear. Trunk volume is rated at 20.5 cu ft (580 L).

In the German home market, the GLC 250 4MATIC petrol version is joined by GLC 220d 4MATIC and GLC 250d 4MATIC diesel versions along with a plug-in hybrid version called the 350e. In North America, only the GLC 300, GLC 43 AMG and GLC 63 AMG are available.
