Thankfully, its engine is more refined the iron-block unit of the old E 220 d Coupé, and its automatic gearbox has been upgraded from a seven-speed unit to a nine-speed one.
Step off is smooth and, with a good deal of torque low down in the rev range, impressively responsive. Gearshifts are crisp and reasonably rapid, even under full throttle. Together with a 23bhp hike in power, the more closely stacked gear ratios result in a 1.1sec reduction in the 0-62mph time of the old E 220 d Coupé, at 7.4sec.
The new E 220 d Coupé also proves wonderfully relaxed and serene at motorway speeds. A word of warning, though: with a 16-litre reduction in fuel tank capacity, down to 50 litres, range can’t match that of the proceeding model, despite a 4.9mpg improvement at a claimed 70.6mpg.
From a dynamic standpoint, the E-Class Coupé does everything you’d expect. There’s an appealing completeness to its chassis engineering and it is hugely competent over a whole variety of roads. However, when coupled with the optional 4Matic four-wheel drive system, as fitted to our test car, it is not exactly gushing with verve, nor is it quite as entertaining as Mercedes-Benz would perhaps have you believe.
Grippy properties ensure there is always plenty of purchase. When you turn in to corners, the car feels willing, and the weighting of its steering builds up nicely to provide a good deal of resistance as lateral forces increases. However, the electro-mechanical set-up is clearly tuned for relaxed handling properties, being rather less direct than one might expect in a car with such overtly sporting overtones.
The optional Air Body Control suspension (along with optional 19in alloys here) does an excellent job, too. There is an obvious degree of body lean when you push hard in corners, but overall body control is very good, ensuring the car is well tied-down and never ponderous.
The ride is also mostly good, delivering impressive compliance and absorbing imperfections around town without too much bucking or shudder through the car's body. However, where the E-Class Coupé really excels is out on the open road, where it delivers settled and comfortable qualities at speed that make it a wonderfully capable proposition for long-distance journeys.
Meanwhile, the interior looks great, and is far roomier than before, especially the rear, which can now accommodate two adults in far greater comfort than the old E-Class Coupé could.
The design of the interior leans heavily on that of other new E-Class models, but it has a number of bespoke touches, including newly designed air vents, automatically extending feeder arms for the front seatbelts and some model-exclusive trim panels. You can optionally have two 12.3in displays, one for the instruments and one for the infotainment system, with the latter being operable either via touchpads on the steering wheel or a rotary dial controller and a touchpad on the centre console.
