Mercedes C-Class Coupe review - Practicality, comfort and boot space

The coupe bodystyle doesn’t stop the C-Class offering acceptable practicality. Rear seat space is tight though

Interior space is reasonable on the C-Class Coupe. Like most cars of this type, space is a little tight in the rear for adults but for shorter journeys it’s adequate. There’s a well-shaped boot and plenty of cubbies and interior storage too.

The front seats fold and move forward quite a way for simple rear access. Long coupe doors and a taller roofline than an Audi A5 mean the back seats are easier to get into, but there’s less room once you're there. Neat touches like the electric seatbelt feeders ensure you needn’t reach too far, so the long doors don’t hit practicality too much. The view out of a coupe can be restricted, but Mercedes offers decent forward and rearward visibility.


At 4,750mm in length and 1,877mm in width, the C-Class Coupe is slightly larger than its biggest rival, the BMW 4 Series Coupe. It’s the same story when you compare it to the Audi A5 Coupe and the Lexus RC – but we are only talking a few millimetres. 

Leg room, head room & passenger space 

Upfront space is excellent, however, as you’d expect, room in the back is rather more restricted. That’s thanks to the sloping roof line meaning anyone over six-foot will really struggle for headroom however kneeroom is just about acceptable and you can slide your feet under the front seats to give a little extra comfort. There are only two seats as well, with a pair of cupholders in the centre – the middle seat has been removed so the two outer seats can be moved inboard allowing passengers a better view our of the front. Overall, space is on par with rivals. 


Apart from the C 63 and C 63 S models, all C-Class Coupes have a 400-litre boot. This is 50-litres smaller than both the BMW 4 Series and the Audi A5. The C63 has even less room for luggage – just 355 litres.
