Mercedes E-class Coupe (C207)

Debut: 2009
Maker: Mercedes-Benz
Predecessor: CLK (C209)


By switching to the E-class name, Mercedes hopes the coupe will have a psychological advantage over its rivals.

In 1968, Mercedes-Benz introduced a hardtop coupe based on its mid-sized W114 saloon. The 250CE, where C stands for Coupe, was renowned for mechanical refinement and an elegant style by its Italian designer Bruno Sacco. That was the ancestor of today's E-class Coupe. Mercedes produced three generations of CE coupes before switching to the smaller CLK-class from 1997. While the latter was a commercial success, it had been finding more and more difficult to fend off the competition from BMW 3-Series Coupe, Audi A5 and Infiniti G37 Coupe. These cars are more dynamically capable yet cheaper to purchase. In order to sustain a price premium, the product planners at Stuttgart decided to terminate the CLK line and go back to its mid-size strategy. As a result, E-class Coupe is born.

By switching to the E-class name, Mercedes hopes the coupe will have a psychological advantage over its rivals, because customers can clearly see its classier status. Moreover, it is part of the company's strategy to reduce its increasingly confusing nameplates. As we know, the next generation CL coupe will also be renamed to S-class Coupe.


Its sleek profile enables a world record-breaking Cx of 0.24

The relationship between E-class Coupe and E-class saloon is evident from its quad-diamond-shape headlights. But everything else is different. There is not a single body panel shared between the two cars as their dimensions and shapes are very different. The Coupe has a much sleeker profile. Its windshield and rear screen are set at fast angles to enable a world record-breaking Cx of 0.24, i.e., one point better than the saloon. Its slopping bonnet is headed by a grille and 3-pointed star badge traditionally reserved for Mercedes coupes. Its side glasses are heavily tapered towards the roof to create a sportier feel. The power bulges around rear fenders have a similar intention. The frameless doors and B-pillarless hardtop design bring a cleaner side view. There is some CLS-class flavours in the banana-shape waistline. However, like the sedan, the E-class Coupe is not a good example of automotive design. I particularly dislike its complicated front end, whose angular elements contrast the smooth body profile. Moreover, the high and curvy waistline creates a sense of fatness so that the rear wheels look at least a couple of inches smaller than they should be. On the road, this car might be as head-turning as CLS because of its heavy-handed design, but from purist point of view it has little to remember.

The interior of E-class Coupe adopts a design similar to its saloon sibling, which means intuitive, high-quality and robust. But since this is a coupe, we should expect something more stylish, shouldn't we ? Fortunately, those good-looking leather seats save the game. The front seats are not only supportive and comfortable, they are also set low enough in the cabin. The two individual rear seats have a similar sporty design as the front (like Porsche Panamera), what a pity they are not the most accommodative in the class - while legroom is abundant, people over 5' 9" (175cm) will have their heads touching the sloping roof. All passengers are cocooned by a high waistline, but a light and airy ambience is made possible by a panoramic glass roof, remarkably narrow roof rails and the lack of B-pillars.


More style would be welcomed to the interior

As in the sedan, you can have a wide range of luxury, infotainment and safety features. However, I suppose our readers are more interested in the mechanical aspect. Although E-class Coupe is supposed to be the coupe version of E-class, I found it actually owes more to the C-class. Look at its dimensions: this car is 117 mm longer than C-class and 170 mm shorter than E-class, 16 mm wider than C-class and 68 mm narrower than the E-class, so it is closer to the former. Most important, its 2760 mm wheelbase is identical to the smaller saloon. What do you think ? Yes, it might be derived from the C-class. Mercedes insisted that it employs more components from E-class than C-class, such as suspensions and powertrains. It just didn't tell us that the new E-class has already switched to C-class suspensions. Moreover, the Coupe does not get Airmatic suspensions, unlike E-class. As for powertrains, it is meaningless to say which ones come from E-class because Mercedes' powertrains are always designed independent of cars. Any new models are free to adopt suitable powertrains from the enormous parts pool.

5 engines are offered on the Coupe: 204hp 1.8 direct-injection turbo (E250CGI), 204hp 2.1 twin-turbo diesel (E250CDI), 231hp 3.0 turbo diesel V6 (E350CDI), 292hp 3.5 direct-injection V6 (E350CGI) and 388hp 5.5 V8 (E500 or E550). As you have read from our E-class report, the V8 offers serious performance but its asking price is out of the reach of most buyers. Moreover, its extra weight compromises handling a little. The petrol V6 looks powerful on paper, but in reality it lacks instantaneous torque compared with BMW's twin-turbo straight-six or Audi's supercharged V6, so it is not the best choice here. The diesel V6 is worth more recommendation for its combination of real world performance and respectable refinement, though a low-revving diesel engine is hardly an inspiring choice. The same goes for the four-cylinder E250CGI, which is willing and refined, if not very quick. It represents great value for money. We praised the four-cylinder diesel E250CDI in our E-class saloon report. In the lighter and sleeker coupe, it delivers an even more incredible fuel economy (55.3 mpg) and emission (135g/km CO2). Nevertheless, the engine is coarse whenever being pushed to upper rev range, thus it can hardly satisfy enthusiastic drivers.


The best part of this car should be comfort and refinement...

On the road, the E-class Coupe shows considerable improvement in handling compared with the previous CLK. There is a new sense of speed and accuracy from its variable-ratio steering rack. The chassis shows tighter body control and better balance in corners. Understeer is better suppressed. Such improvements are brought by the "Agility Control" suspensions, which employ two-stage mechanical adaptive dampers. If you opt for "Dynamic Handling" pack, which is an affordable option on all sport models and standard on E500, you'll also get electronic continuous adaptive damping, gearshift paddles and a Sport button which switch to sportier suspension, throttle and transmission mapping.
You can have the E-class Coupe set as a sports coupe or a comfort coupe depending on your mood. In sport mode, it flows through winding back roads more fluently, giving you more confidence. Admittedly, even then the Mercedes coupe is not as agile as a BMW 3-Series Coupe in sport suspensions. To preserve a ride quality that Mercedes needs, it leaves some body roll and understeer unrectified.

In Comfort mode, or on standard suspensions without Dynamic Handling pack, the E-class Coupe rides nicely - slightly firmer than E-class saloon but perfectly suitable to a civilized coupe.
Only the E500 on 18-inch rims and low-profile tires would generate some harshness over bumpy roads.

Unsurprisingly, the best part of E-class Coupe is still comfort and refinement, especially how it is driven relaxingly cross country. The way it cruises at high speed with little wind noise, engine noise and road noise is impressive. Its high-speed stablity, its refined steering and ride ease your fatigue over long journey, let you enjoy the great view from the paranomic glass house. Use the Command voice recognition to play your favourite Jazz, let the radar cruise control, lane departure warning and blindspot warning to relieve your pressure... relax... and relax... Just as you fall asleep, the drowsy alert sounds a warning chime to wake you up. It's time to have a coffee at road side cafe. If you enjoy luxury motoring, E-class Coupe should be the cheapest entry point.

E-class Cabriolet



Even at 70 mph, you can talk in regular volume to passengers at the back. Such refinement is unprecedented in the open-air motoring world...

It is easy to see why Mercedes E-class Cabriolet can charge more money than the equivalent BMW 3-series Cabriolet or Audi A5 Cabriolet. The family name E-class might help, but from many areas you can feel the Mercedes open-air car is better designed and more exclusive than its counterparts. One problem is common to its rivals: they look like coupes minus roofs. That is to say in pursuit of open-air motoring, you have to sacrifice a little bit style. The Mercedes is on the contrary. While the E-class Coupe looks a little bulky, cutting the roof actually makes the Cabriolet slimmer and more charming. So this is not a coupe minus something, but plus something.

Another thing I don't like other cabriolets is they treat rear passengers as second-class citizens. Not so in the E-class Cabriolet. Six-footers can sit comfortably at the back unless the front occupants are unusually tall.

Space aside, Mercedes seems to understand the needs of open-air motorists better than everyone else. If you want to enjoy sunshine in winter, the "Airscarf" seat blows hot air to keep your neck warm. If your rear passengers dislike the wind buffeting at cruising speed, you can activate the new "Aircap" feature, which deploys an aerodynamic foil a few inches from the windscreen header, deflecting the air flow upward and greatly reducing buffeting to the rear passengers. It also makes the cabin a lot quieter. Even at 70 mph, you can talk in regular volume to passengers at the back. Such refinement is unprecedented in the open-air motoring world.



Jumping from the E-class coupe to the cabriolet would not find a remarkably difference in driving fun - or the lack of it.

Unlike BMW, Mercedes wisely decided to keep using conventional fabric roof instead of switching to folding metal roof. This result in a weight increase of 120 kg, versus 210 kg in the case of BMW 3-Series Cabriolet. Mercedes' 3-layer soft roof is a quality work. It keeps the cabin quiet at motorway speed. It opens or closes in just 20 seconds, and is operable at speed up to 25 mph. It eats little trunk space. Luggage volume is 390 liters with the roof up or 300 liters with it stored, much better than BMW's 350 and 210 liters respectively.

Expectedly, the cabriolet is not quite as stiff as the coupe despite of some underfloor reinforcement. However, by the standard of cabriolets its chassis rigidity or running refinement is beyond criticism. Unless you push it on really bad roads, the E-class Cabriolet hardly shows any scuttle shake or chassis flex. On regular roads, you can expect superb refinement in terms of ride and powertrain smoothness.

A wide range of petrol and diesel engines are available. Best selling of them should be the 292-horsepower direct-injected V6 of 350CGI. However, we find the 3.0-liter V6 turbo diesel of 350CDI the sweetest of all. It is not only more frugal but also more refined than the slightly underachieved 350CGI. On paper, it hardly loses any performance to the petrol V6. In real world, you will feel the difference made by its 398 pound-foot of torque from just 1600 rpm, which translates to instant acceleration when you need to overtake other cars. Moreover, the mountain of torque calms down the 7G-Tronic gearbox, which is busier in hunt for gears in the 350CGI. The V6 turbo diesel could have made the range-topping 5.5-liter V8 redundant if
America were offered with super low sulfur diesel.

Then what about handling ? Considering cabriolets are designed for more laid-back driving style, the E-class Cabriolet's emphasis on refinement is more suitable to the task than either 3-Series Cabriolet or A5 Cabriolet. At least, jumping from the E-class coupe to the cabriolet would not find a remarkable difference in driving fun - or the lack of it. The same cannot be said to BMW. For all these reasons, Mercedes deserves the slight premium it asks for.
