Core summary
U.S. MY2023 GLC 300 SUV and GLC 300 4MATIC SUV. Source-based specification and buying analysis.
The GLC 300 decision begins with driven wheels and the equipment you will use. Keep SUV and Coupe listings separate so that body-style differences do not disappear behind one badge.
History & generations
This reference covers the redesigned X254 GLC SUV for U.S. model year 2023. It does not include the Coupe or other markets' plug-in variants.
Body, platform & design
Mercedes lists a 185.7-inch length and 113.1-inch wheelbase for this SUV.
Engine & drivetrain
The 2.0-liter turbo produces 255 hp and 295 lb-ft, with temporary integrated-starter-generator assistance and a nine-speed automatic. Rear-drive and 4MATIC versions are offered.
Trim differences
Compare packages against a written must-have list before choosing 4MATIC by default. Drivetrain need and cabin equipment preference are separate decisions.
Interior & seating
An 11.9-inch portrait center display, 12.3-inch driver display and 40/20/40 folding rear seat are listed in the U.S. guide.
Efficiency & range
The guide quotes 28 mpg combined for rear-drive GLC 300 and 26 for 4MATIC. These figures should not be reused for a different model year without checking.
Safety & equipment
Confirm camera and assistance equipment on the actual car. A feature illustrated in a launch guide may depend on drivetrain or equipment package.
Strengths
Its strongest argument is the SUV packaging combined with the particular cabin interface you prefer. Verify those benefits in person rather than assuming the redesign automatically suits you.

Considerations
Try climate, navigation and phone functions before judging the portrait screen. Daily interactions matter more than the amount of display surface visible in a photograph.
Recommended use
For family trips, use the split rear seat with the luggage and remaining passengers in place. That establishes whether the flexibility is useful in your specific arrangement.
Rivals & related
Compare the previous-generation GLC only after identifying which redesign changes you want. Compare the Coupe independently if its roofline, rather than SUV utility, is the attraction.
FAQ
Does mild hybrid mean this GLC can be charged from a socket? No. The U.S. MY2023 GLC 300 reference is not a plug-in-hybrid specification.
