Mercedes CLA Coupe

The Mercedes CLA Coupe cuts a rakish silhouette that blends sporty coupe lines with everyday practicality, giving style-minded buyers a premium image without shouting. Inside it feels more luxurious than its size suggests, with a slick cabin, intuitive tech and a composed ride — the kind of car that parties in the city and still shows up polished on Sunday morning.

We've been driving the Arkana RS Line mild-hybrid for almost five years — and we're mega satisfied. At first everyone turned to stare. It's a good car to cover motorway miles, and fuel consumption of about 6.4 l/100 km is acceptable. Since our contract is ending, we're parting with the Arkana despite the lovely years together and switching to the Symbioz full-hybrid 160 Alpine Line. Hopefully we'll have a great time with it too.

An excellent compromise between styling, practicality, space and fuel consumption. It’s not a sporty coupe, but practical for everyday use, with balanced purchase and running costs.
