ROMEI should be drinking in the vivacity of the Trevi Fountain. Or maybe the ruby-hued bottle of Chianti I liberated from the hotel minibar? No, instead I’m sitting in the back seat of a coupe — a four-door coupe — trying to wrap my brain around the very idea that such an animal exists.

Review continues below

Now, two-door sedans are a reality. Pretty much every BMW 3-Series two-door still qualifies as a sedan, by EPA measurements. But anything with four doors is plainly a sedan. Right?

Not by the yardstick applied by a growing number of car companies, who can identify those of you who still want four-door practicality but the sleeker silhouette of a vehicle with fewer orifices. Audi’s new A6 is one of these animals, but possibly the most hotly intent on selling the idea is Mercedes-Benz via its new CLS.

The CLS, Mercedes vows, offers up the “elegance and dynamism of a coupé with the comfort and practicality of a saloon.” Translation: you don’t lose the room or trunk space of a typical four-door, even though the body is styled to look more like a coupe. And in the case of the CLS, which shares roughly 35 percent of its body structure with the conventional E-Class four-door, most of the functional goodness is retained beneath an intriguing new skin.

The very Gaul

You’ll look twice or even thrice at the CLS’s glam new shape, a gamine and slightly tawdry take on the E’s rather upright demeanor. (In Atlanta, a white E-Class is a hallmark of “Buckhead Betty” status, which wins you a lifetime of valet parking at Lenox Mall along with other ladies who lunch.) The CLS a hussy all right, with more voluptuous fender swells, a tighter rear end and a youthful cleft from nose to tail. If we can indulge in a cultural stereotype for a brief moment, our French ancestors would characterize the CLS as the mistress to the E-Class’ wifely duty.

It’s appropriate, because in many ways it’s as if Mercedes set out to build a French car, soft and forgiving (even to us Americans!) and prepossessed not by speed but by comfort. The evidence is copious: the instrument panel morphs from the E-Class’ Teutonic rigor into Monet softness, empanelled in your choice of dark or light wood, in matte or gloss finish. Wait, are we ordering a car or lipstick? Wood and leather ring the steering wheel as well, and the seats are padded in creamy leather.

If you’re looking for hints on heritage, the mass of electronics underneath gives away the German heritage. There are electronic devices and gadgets to take care of most of the car’s bodily functions and the names will honestly depress you in their dullness. If you have to know, the Parktronic system keeps you from backing up into yard kerbies; Distronic uses radar to keep your cruise control from homing in on the car in front; Linguatronic understands your commands and informs the navigation system and audio controls per your wishes; Thermotronic is the four-zone system that pumps out enough air to mimic a new home; and Sensotronic takes over actual braking for your right (or left) foot, transmitting force to a computer that interprets how much brake power you need.

We know the intentions are good. But with all the buttons and switches and even with voice-activated help, controlling the secondary systems at a roll can be confusing as playing whack-a-mole while piloting a 737. Set and forget before you engage, please.

Rev it up, monsieur

With the available Keyless Go system, there’s no need to even pull the key from your man purse. (Call us surprised, too — Benz says the percentage of men buying the CLS will be even higher than in the E-Class.) Just clamber in — watch those Abboud slacks, you just got them out of the dry cleaners — and press the Start/Stop button domed atop the gear selector. The 5.0-liter V-8 awakens and the seven-speed automatic gearbox awaits further instruction.

Set out apace and the lovely V-8 canto will encourage you to explore the CLS’s talents. It’s a marvelous engine, and though we didn’t care for the seven-speed in the sporty Boxster-baiting SLK, here it’s perfectly suited for duty. Upshifts are undetectable, downshifts of two or three gears are nearly as smooth, and as the best transmissions are, the seven-speed’s action is a complement to the CLS’ character, not an off-note. Coupled to the 302-hp V-8, it assists the CLS to 60 mph in about six seconds on its way to a top speed of 155 mph.

The powertrain feels as similar to the E-Class as any fraternal twin would to their wombmate, but the CLS’s steering and suspension are set noticeably apart from the standard E. There’s more play on center with the Active Steering option, and cornering forces build artificially, though the interplay is far from sloppy. The Airmatic suspension, which lowers the CLS six-tenths of an inch at speed, tends to allow body impacts to shudder through the car’s structure in a way we don’t recall in the E-Class. Three settings allow drivers to choose the softness or stiffness of the Airmatic setup, and both my co-driver and I thought it was best in the stiffest setting.

The electronic parade washes the CLS’ cabin in safety gear. There are dual front airbags, side thorax and side curtain airbags, a tire-pressure monitor, and stability control, all standard.

But we ingress

If the dynamics of the CLS show the softer side of Mercedes-Benz, the rear seat sets the tone for the notion of the “four-door coupe” and the compromises it entails. Officially, the line is that the CLS’ sloping roofline allows rear passengers to enter and exit the car in comfort. We’d agree for people shorter than six feet; as in other cars with radical rooflines and lots of side-profile slope (tumblehome), it’s easy for heighty types to clock our heads against the roof on the way into the twin buckets in the rear. The elbow room in back is fine, since there’s no pretense of a fifth passenger riding on the transmission tunnel, but the headliner encroaches on the noggins of the taller riders.

The trunk has been spared too much cutting. The drop-off decklid leaves behind a usable 17.8 cubic feet of trunk space, and Benz adds on a motorized lid in case you’re too infirm — or important — to close it manually.

In front, it’s a better story, though the lower roofline can have the same hair-pulling effect. So can the new buckets available on the CLS — multiadjustable units that have inflatable bladders that offer literally thousands of potentially comfortable seating positions. Customize it, play with the settings or turn on the massage function and save yourself a trip to the Tokyo Spa out by the rest area. Base buckets have power functions, and can be ordered with seat-cushion ventilation (“butt conditioning”? "Asstronic"?).

The CLS is an unusual vehicle for any automaker not headquartered in Paris. For Mercedes, it’s even more a stretch, given the fundamental goodness of the E-Class and the resistance to changing its winning formula. But then, Mercedes doesn’t expect huge waves of clients to switch allegiance to the CLS: they plan only about 30,000 units per year, with 10,000 coming to America, which explains why no all-wheel-drive option will be offered. (A six-cylinder CLS350 is virtually assured, however). For those who prefer a subtler flavor of E-Class with four doors and hardtop style, the CLS caters to your needs exquisitely.
