One of the most comfortable cars you'll ever travel in, genuine four-seater, entry-level V8 provides reasonable fuel economy.

Not a true driver's car, nine-speed auto prone to odd bout of confusion, Active Curve System struggles with British B roads.

Mercedes-Benz S-Class Coupe (2014): At A Glance

Beautifully engineered, filled with useful tech and effortlessly fast, the Mercedes-Benz S-Class Coupe is German car building at its very finest. It might not be a true driver’s car, but few grand tourers match this big Benz for opulence or comfort.

The Mercedes-Benz S-Class Coupe is a big visual leap from the old CL-Class, with a domed roof and heavily sculpted flanks. Some may say that the optional 47 Swarovski crystal headlamps are a step too far, but the S-Class Coupe makes an imposing statement on the road.

Like the S-Class limo, the interior is lavish and filled with soft-touch leathers, polished metals and hand finished wood trims. The S-Class Coupe is a genuine four-seater and has enough boot space for six cabin-sized suitcases. The individually contoured seats are excellent over a long distance drive, but making a dignified exit from the rear seats is a near impossible task with the huge front seats making it difficult to climb out.

Despite its impressive choice of V8 and V12 engines, the S-Class Coupe is not a car that scores highly for dynamic, sports car handling. The air suspension robs the majority of the feel from the chassis and steering, while the car's colossal size - and 2.1 tonne kerb weight - provides the occasional bout of anxiety when navigating narrow or twisty county roads.

It might not be the sharpest tack in the box when it comes to handling, but the S-Class Coupe is certainly one of the most comfortable. Point the five metre long Mercedes-Benz at a British motorway or German Autobahn and it'll cover huge distances with the soft and relaxing grace of a supercharged cloud.

The swooping dashboard is home to a pair of bonded widescreen displays, which makes it easy for the driver to customise the instrument binnacle and central screen with maps, media or technical information for the vehicle. However, while the Comand online system is impressive, it’s let down by slow-witted navigation.

Mercedes-Benz has some accomplished competition in the GT market, but this offering more than holds its own on the road, while its exceptional build quality puts some of its costly British rivals to considerable shame. As long distance grand tourers go, the S-Class Coupe is among the very best.

Full specifications

The cabin of the S-Class Coupe feels more akin to an executive jet than a GT car, with dual HD cockpit displays, handstitched leathers and brushed aluminium switches providing a true first class experience.

Despite the low slung, two-door design, the S-Class Coupe is a genuine four-seater. Admittedly, getting in and out of the rear seats is a bit of an assault course, owing to the size of the contoured seats in the front, but once fully loaded the S-Class Coupe is every inch as classy and comfortable as its saloon-shaped counterpart. It also has a 400 litre boot, which is larger and far more useable than anything you'll find in its rivals from Aston Martin or Bentley.

The S-Class Coupe easily matches its more expensive British rivals for comfort, with its individually contoured seats providing the same comfort as set of soft-cushioned armchairs. However, while head and legroom is generally fine all-round, the tallest passengers in the rear seats will need those in the front to slide forward to get the best fit.

As a two-seater, the S-Class Coupe has acres of space. Both of the front seats get four-way electric lumbar adjustment and the option of a heated massage system that will sooth your back on those long, cross-continental drives. The large panoramic roof fills the cabin with natural light during the day, while ambient lighting - with 64 colour settings - adding a soft warm glow when the sun has set.

In keeping with its executive airline appearance, the S-Class Coupe is whispery quite at motorway cruising speeds, with its thick windows eliminating almost all road and wind noise. The optional Magic Body Control system also reduces body pitching in the corners, with the car leaning into bends by up to 2.5 degrees to reduce the lateral acceleration acting on the vehicle's occupants.

This means the S-Class Coupe will glide around a sharp motorway slipway, without any unpleasant body roll; however, the system suffers the odd bout of confusion when confronted with a rough B road which results in the occasional supressed thud.

The curved dashboard houses two 12.3-inch screens, which are operated via a rotary wheel next to the armrest or by touchpad controls on the steering wheel. The system is easy to use for the most part, with lots of customisation options - maps, engine data, media and climate control - for both the central display and instrument binnacle. The only disappointing aspect of the Mercedes-Benz Comand system is the navigation, which is slow to react and prone to missing road closures or traffic delays.

What's the Mercedes-Benz S-Class Coupe (2014) like to drive?

The S-Class Coupe is a monstrously powerful grand tourer that’s prioritises comfort and refinement over handling. This means its light steering and soft air suspension nullifying much of the feedback you would traditionally get from the chassis, steering and pedals. That’s not necessarily a bad thing, especially if you are in the market for a GT car that's designed for wafting over the motorway miles.

Measuring more than five metres long and two metres wide, the S-Class Coupe feels undeniably large in town, but its light steering and abundance of driving aids make it surprisingly easy to guide into a parking space or down a narrow one way street.

On the open road there is very little to criticise, with the soft ride quality, quiet and airy cabin making long drives a genuine pleasure. However, while the air suspension can be tailored with active ride height control and a curve function to mitigate bodyroll on the corners, there is no hiding the fact that this is a car that's designed for the motorway. Head onto the twisty stuff and the S-Class Coupe feels too large, too vague and too much like the S-Class saloon to return any fulfilment. For most buyers, this will not matter. 

The entry-level S560 is the most-rounded model in the range, with the V8 producing a healthy 469PS at 5250rpm and 700Nm at 2000rpm. As you might expect, with so much low-gear torque, the S560 pulls strongly through all of the gears. The 0-62mph sprint takes just 4.6 seconds to complete, which is impressive for a 2.2 tonne GT.  

For the most part, the 9G-Tronic automatic transmission is a worthy match for the 4.0-litre twin-turbocharged petrol unit, but at lower speeds it can be prone to the odd moment of befuddlement with questionable gear changes. These usually manifests at roundabouts and junctions when you have to pause to find a gap in the traffic. On the motorways, however, the nine-speed ‘box is smooth and painless to use.

Those wanting more punch from their big Benz can choose between two AMG-badged models: the S63 AMG uses the same V8 engine as the S560, but develops 612PS and a uses a MCT nine-speed automatic that's sharpened to cope with the engine's 900Nm of torque. The 6.0-litre V12 uses a 7G-Tronic auto and produces 630PS and 1000Nm of torque- both cover 0-62mph in around four seconds and are electronically limited to 155mph. 

When it comes to fuel economy, it could be argued that those who need to ask cannot afford a Mercedes-Benz S-Class Coupe. But for the record the S560 returns an advertised 27.7mpg while the more powerful S63 AMG manged 25.9mpg. The fire breathing S65 AMG managed an official 19.9mpg, but expect single figures if you push it on a spirited drive.  

Engine MPG 0-62 CO2
S 500 32–33 mpg 4.6 s 197–204 g/km
S 63 AMG 28 mpg 4.2 s 237 g/km
S 65 AMG 24 mpg 4.1 s 279 g/km
