The Mercedes-Benz CLA (C117 generation) was launched in 2013 as a '4-door coupé' derived from the A-Class (W176), based on the MFA front-wheel-drive platform. It stands out with its flowing design, record aerodynamics (Cd of 0.22), and frameless doors. A facelift occurred in 2016, bringing standard LED lights, new bumpers, a refined infotainment screen, and a slight improvement in perceived interior quality. Although aesthetically very appealing, it sacrifices rear spaciousness and visibility for style. Mechanically, this report focuses on the diesel offering (very popular in Europe for high-mileage drivers), shared between the 1.5L Renault-sourced engine (OM607) and the 2.1L 100% Mercedes engine (OM651), while also providing an exhaustive overview of global gasoline engines.
The Mercedes CLA C117 is an 'emotional purchase' that prioritizes style over practicality. For diesel engines, the choice depends on your usage. The CLA 180 d (Renault engine) is paradoxically the most rational and reliable choice for daily and economical use, provided the belt change is respected. The CLA 200 d / 220 d (Mercedes OM651 engine) offers better performance for high-mileage highway drivers but requires absolute vigilance regarding the maintenance of its timing chain and the 7G-DCT gearbox. Opt for a facelifted model (post-2016) for better assembly quality and more reliable electronics.
