Mercedes C-Class Coupe: old and new compared

The all-new Mercedes C-Class Coupe has been officially unveiled, and this new BMW 4 Series and Audi A5 rival will go on sale for UK customers in December.

The German brand claims that this new model is faster, quieter, more efficient and more luxurious than its predecessor, so we have compared the pair side-by-side to find out what has changed.


The outgoing C-Class Coupe looked very much like a regular C-Class Saloon shorn of two rear doors. Approach the new Coupe from the front and it may still seem that way, but look at the rear and the complete redesign is obvious.

The sloping roofline and smooth, wide tail lights are more reminiscent of the S-Class Coupe than they are of either the current C-Class Saloon or the previous-generation Coupe, and that helps it stand out from either. The side in particular looks far more graceful than before, and it helps give an overall impression of a much pricier car. These styling tweaks aren’t just cosmetic either — the latest Coupe boasts an impressively low aerodynamic drag figure, helping to improve overall fuel efficiency.


The old C-Class Coupe was based on the previous generation C-Class saloon, and as a result shared much of that car’s interior design. The new model — taking the current C-Class as a starting point — features a much more contemporary and handsome interior, which won the saloon our interior of the year award in 2014.

The new car is 40mm wider and 80mm longer between the wheels, both of which contribute to greater cabin space in the front than before. However, a steeply raked roof line means that taller passengers sat in the back might notice that it isn’t quite as roomy as before. The front seats are located 25mm lower than the saloon for a sporty driving feel, and the front seatbelts electronically move forward to greet you as you get in, reducing the need to reach awkwardly behind you to belt up.

As you’d expect from a modern Mercedes, the C-Class Coupe is loaded with gadgets. With the help of a Bluetooth-enabled mobile device, the infotainment system provides internet capability as standard. Even the climate control is clever: it pairs up with the satellite navigation so that it knows when you’re driving through a tunnel. It then switches to recirculation mode for the duration to stop exhaust fumes entering the cabin.

A wide selection of new interior colours also separates the Coupe from its forerunner, with high quality leathers and soft touch materials stitched to as many surfaces as possible.


Thanks to an increased use of aluminium and other lightweight materials in the Coupe’s construction, the latest C-Class is as much as 90kg lighter than the model it replaces, and that’s despite the overall increase in size. The structure is stiffer, too, allowing for greater suspension control and reduced noise levels.

The C-Class Coupe rides on regular springs and dampers as standard, but can also be specced with optional air suspension. This electronically-controlled air system constantly adjusts the rate of shock absorbers to deliver the best possible compromise between ride comfort and handling balance. Depending on the driver’s mood, it is possible to switch between Eco, Comfort, Sport, Sport+ and Individual modes.

This doesn’t just adjust the suspension characteristics though — it also alters the behaviour of the automatic gearbox and the throttle response to deliver the most suitable feel according to each mode.


In comparison to the fairly limited choice of one petrol and two diesel units in the old car, the 2015 version can be equipped with one of four petrols and two diesels. The entry-level C 180 is an updated example of the 1.8-litre turbocharged engine found in the previous model, producing the same 156hp. Above that sits the 184hp-rated C 200, a 211hp C 250 and the C 300, which has 211hp. All three use a two-litre turbocharged four cylinder block.

The diesel pair produce the same power as in the old car — 170hp and 204hp — but, like the petrols, now meet the latest Euro 6 emissions standards. a combination of the updated engines, lower weight and aero-efficient shape means that Mercedes claims that like-for-like the new Coupe is 20 per cent more fuel efficient than the old car.

The most powerful version of the new C-Class Coupe is the Mercedes-AMG C 63 S, which will have 510hp and rocket from 0-60mph in 3.9 seconds.

Value for money

The outgoing coupe was marginally more expensive than the equivalent saloon, and although Mercedes hasn’t confirmed exact pricing yet, expect the same to remain true.

A wide-ranging and comprehensive safety kit list should help the latest C-Class Coupe be more secure than ever — despite the old car already achieving the maximum five-star rating when it was tested by Euro NCAP.

The systems are numerous. Attention assist can warn the driver if they are feeling drowsy or if they aren’t paying attention to the road enough, while Collision Prevention Assist alerts the driver to dangers, priming the brakes to ensure the shortest possible stopping distances. It can even perform an emergency stop autonomously if necessary.

Other optional features include Mercedes’ latest adaptive cruise control system, which can steer between the lanes of a motorway, and even follow the direction of the car ahead if lane markings are unclear. Park Assist allows for semi-autonomous bay and parallel parking, while a 360° camera gives the driver a bird’s-eye view of the car while manoeuvring in tight spaces.


If you’re keen on placing an order for a C-Class Coupe, we’d recommend holding fire just a little while longer so you can get the new one. This version should be a step up from the old one in almost every measurable way, and to our eyes it’s prettier too. Not that the old coupe is a bad car by any means — it’s just than the 2015 model moves the game on considerably.
