2009 Mercedes-Benz CLS

Fast, luxurious, beautiful. edited by New Car Test Drive

Walk Around

The Mercedes-Benz CLS is a four-door car with the ambience of a coupe, and a beautiful coupe at that. This is one of the most striking four-passenger cars anywhere.

The sedan quality derives from one obvious characteristic. It has four large, conventionally hinged side doors that allow unfettered access to both the front and rear seats.

Its coupe qualities are harder to define, but it's that makes the CLS so interesting and attractive. And it's not just its long, low-slung profile. It's the frameless side windows, the barely-visible center roof pillar, and the descending slope of the rear pillar, which blends into muscled rear fenders. A pronounced shoulder line sweeps back from the front wheel arch, creating a wide, tall-waisted stance, as though the car has been stretched by the wind. It's hard to believe that a tilt/sliding glass sunroof will fit within the arching roofline, but it does.

The front of the car thrusts visually forward with prominent grille slats, a deeply wedged hood and fenders that dive steeply into the distinctive headlamp clusters. A deep bumper forms a coupe's characteristically muscular rear, braced by two chromed exhaust pipes.

The CLS features details that reduce noise when cruising at high speed. Look closely and you'll discover things like plastic deflectors in front of the front wheel arches to improve airflow across the front axle links, aerodynamic cladding on the rear axle spring links, and mini-spoilers in front of each wheel to reduce dynamic pressures at the tires and improve airflow around the wheels. Even the wiper arms were refined in the wind tunnel. These aerodynamic wipers feature a mounting system and integrated spoiler for better wiping with less noise.

We're not sure we love the looks of the aggressive lower body cladding on the CLS63 AMG. It's just not as pretty as the CLS550. The staggered-width, 19-inch five-spoke AMG wheels look fantastic. The deep front and rear aprons and sculpted doors sills are anything but ugly, yet they take away of the graceful shape. That's sometimes the case with racy versions of beautiful cars.

The CLS cuts a fairly slippery profile, with a drag coefficient of 0.31, low for such a sculpted four-door car. This aerodynamic efficiency contributes to overall fuel efficiency and reduces wind noise at high speeds. The AMG rides a half-inch lower than the standard CLS.

Interior

2009 Mercedes-Benz CLS

Inside, the Mercedes-Benz CLS has the bespoke quality of some of the world's most expensive sedans. This richness flows from good, clever design as much as from the materials used.

The view forward is filled by an expanse of burr walnut that stretches between round vents in the far corners of the dash, finished in a silk matt rather than the high-gloss familiar in many Mercedes. The walnut surface is broken by recessed center air vents, the climate control switch cluster and the main instrument cluster, which features three chronometer-style gauges and two LCD bar graphs for fuel level and coolant temperature. Each gauge is ringed with chrome, as is the cluster as whole. The graphics are crisp, and covered with a special mineral glass that virtually eliminates glare.

Fit and finish is terrific, and the custom-tailored feel is enhanced by the design. Note how the front passenger airbag door blends perfectly into the upward sweep of the walnut panel. Note how the chrome-and-walnut theme carries down through the center console, with a ring surrounding the transmission shift lever, and into the rear cabin, with a separate walnut panel and chrome trim for the rear-seat climate controls. Note how the curve of the center rear console is reflected in the reverse curve of the outboard armrest.

All four seats are covered in leather, with a thicker, richer Nappa finish in the CLS63 AMG. The standard front seats are adjustable 10 ways, using Mercedes' patented seat-shaped switches. There are three memory storage settings, and they can be matched to the remote key fob. Most switches are conveniently placed. A color display screen incorporates audio controls, navigation system and most other functions into a single set of switches. It takes time to learn, but I prefer it to the point-and-click devices in many luxury cars.

The standard harman/kardon Logic 7 stereo sends 480 watts of audio through 12 speakers. Digital processing allows the driver to tailor sound to his or her taste, or to create a surround effect for any seating position.

In the rear seats, the sexy exterior styling results in a decrease in headroom, compared to a Mercedes E-Class. As part of our familiarization with the CLS, we were chauffeured across Rome so that we might see how the rich and famous do it. Tough job. My six-foot frame was comfortable on winding city streets, but passengers much taller may step out of the CLS with a crick in the neck.

Trunk space is not a problem, however. With 15.9 cubic feet of volume, the CLS trunk offers exactly the same space as the E-Class sedan, and not much less than the larger S-Class sedan.

In terms of interior comfort, the CLS makes for a great four-passenger sedan.
