Driving experience

Mercedes-Benz C-Class

The W205 leans fully into the Mercedes comfort remit: it wafts rather than corners hard. The ride is plush, the cabin library-quiet at speed, and the 9G-Tronic dissolves shifts so completely you forget it is there. The steering is relaxed and low-effort, matching the unhurried character. Engines matter more than chassis here: the M274/M264 petrols are smooth and unobtrusive, the OM654 diesel is the one to have, and the plug-in covers town trips almost entirely on battery. AIRMATIC, where fitted, turns poor roads into a distant murmur. It does not ask to be driven hard — it makes every journey feel shorter than it was.

Mercedes-Benz C-Class

Serene, refined and quietly effortless to drive. The W206 puts comfort first: the ride is supple and isolating, the 9G-Tronic shifts are seamless, and the cabin stays hushed at speed. Steering is light and precise rather than talkative, and the body rolls a little more than a 3 Series in corners, but it never feels unsettled. 4MATIC adds all-weather traction without changing the relaxed character. Every engine is a 48-volt mild hybrid, so the petrols are smooth and eager, the diesels pull strongly and stay quiet, and the C 300 e plug-in glides on electric power around town. Overall a calm, tech-rich executive saloon that trades ultimate sportiness for effortless long-distance comfort.
