Mercedes-Benz GLC Coupé: C253 and X254 generations, engines and trims
The Mercedes-Benz GLC Coupé is a mid-size luxury SUV with coupé styling, built on the GLC platform. We take a look at the C253 and X254 generations, the most popular engines, the trims and what to check before buying a used example.
GLC Coupé in brief
The GLC Coupé debuted in 2016 as a coupé-styled version of the GLC, with a lower and more sloping roofline. It competed with the BMW X4 and other similar models, and its distinctive looks were its main advantage.
Compared with the standard GLC, boot and rear-seat space are a little tighter, but the car still offers all-wheel drive, a comfortable ride and a luxurious Mercedes-Benz cabin.
Which generation to choose
C253 (2016–2023) — the first generation, which is widely available on the used market. Updated versions from 2019 got a newer cabin with the MBUX system, improved engines and more up-to-date equipment, making them the more worthwhile choice.
X254 (from 2023) — the new generation, with a larger digital display, mild-hybrid technology and plug-in hybrid versions. On the used market they are still quite expensive.
For the more budget-conscious buyer, it is best to look for a 2019–2022 C253 with MBUX, while the earliest years (2016–2018) should only be chosen with a full service history.
Engines and gearboxes
In the C253 generation, the most popular diesel models are the GLC 220 d and 250 d, while the petrol versions are the GLC 250 and 300. More powerful variants are also offered: the GLC 350 d (V6 diesel), GLC 43 AMG and GLC 63 AMG, plus the GLC 350 e plug-in hybrid.
The facelifted C253 brought in the 200 d and 300 d diesel engines. Most cars have a 9-speed 9G-TRONIC automatic gearbox and 4MATIC all-wheel drive.
In the X254 generation, mild hybrids and plug-in versions are offered, but they are still scarce on the used market.
What to check when buying a used GLC Coupé
First, check that the engine runs smoothly, without unusual noises or smoke. On diesel cars, it is worth checking the condition of the diesel particulate filter, as well as the AdBlue system if fitted.
Test the automatic gearbox, all-wheel drive and brakes. If the car has air suspension, make sure it doesn't sag and that there are no fluid leaks.
Check that all electronic functions work — the MBUX system, cameras, heating and driver assistance systems. Verify the mileage against the service history.

Most cars on the market feature 4MATIC all-wheel drive, though rear-wheel-drive versions do occasionally pop up. Always check the exact specification using the seller's data.
