KBB Editor's Overview

By Editorial Staff

Mercedes-Benz spawned the “4-door coupe” revolution, and the 2015 CLS-Class coupe proves it still owns the segment. New for 2015 is the Mercedes-Benz CLS400, a twin-turbocharged V6 entry-level model set to do battle with the Audi A7 and BMW 6 Series Gran Coupe. A more powerful front-end design lessens the original car’s sleek, streamlined appearance, but keeps the CLS in line with MB’s other 4-door models. Power, speed and superb handling are the 2015 CLS’ trademarks, combined with a sense of exclusivity that seems to elude lesser brands. Those who desire an even more exclusive calling card will appreciate the 577-horsepower provided by CLS63 AMG S 4Matic, although they might not be as enamored by its $100,000-plus price tag.


You'll Like This Car If...

The Mercedes-Benz CLS-Class "coupe" for 2015 is the 4-door sedan for people who prefer the look and feel of a 2-door coupe. As fast as it is stylish, the Mercedes-Benz CLS coupe should appeal most to those who place form over function.

You May Not Like This Car If...

True to its coupe formula, the 2015 MB CLS doesn’t offer much in the way of a comfortable rear seat or roomy trunk. Those who can’t manage the lofty price of a more spacious Audi A7 can get similar styling from the more affordable VW CC or Hyundai Genesis.

What's New for 2015

2015 sees the introduction of the CLS400 turbo-V6 model, as well as a major facelift for the entire CLS-Class lineup. A standing view screen is added to the sculpted dash, while the rear-drive CLS550 gains a new 9-speed automatic transmission. The CLS63 AMG S becomes the sole AMG offering.

Driving It

Driving Impressions

Mercedes-Benz’s CLS550 4-door coupe for 2015 might not be the best car for passengers, but it is a driver’s dream come true. With its twin-turbocharged 4.7-liter V8 pumping out 402 horsepower, the CLS550 can rocket off the line, pass with authority and cruise effortlessly at high speed for hours on end. If quick isn’t quick enough, a move up to the all-wheel-drive 577-horsepower CLS63 AMG S 4Matic is in order. Bolstered by AMG’s impressive suspension and engine tuning, the CLS63 AMG S can dash to 60 mph in less than four seconds, placing it in line with the world’s best performance sedans including the Audi S7 and Porsche Panamera Turbo. From behind the wheel, the CLS inspires confidence in hard cornering and high-speed lane changes, feeling both smaller and lighter than it actually is. Around town, the CLS rides hard but is still civilized enough to earn its 3-star badge.

Favorite Features

MB’s ingenious Adaptive High-Beam Assist uses cameras to detect oncoming vehicles and dim one or both high beams. The system can also adjust the beam’s range. Optional full LED headlights provide maximum illumination.

Directly responsible for the CLS’ responsive and linear driving dynamics, this system actually increases fuel efficiency by drawing power from the engine only when actual steering takes place.

Vehicle Details


Inside, the 2015 Mercedes-Benz CLS offers all the lavishness and technology one would expect at this price point. Elevated levels of detail can be found in the dash design, the intricate stitching on the seats and door panels, and the unique wood trim colors and textures. The CLS’ cockpit is defined by near-perfect ergonomics and a solid, tactile feel. Seats are highly bolstered and designed for both spirited driving and long-distance cruising. However, don’t look for matching comfort in the rear seat area, where both headroom and legroom are in short supply.


For 2015, the Mercedes-Benz CLS 4-door coupe is as distinctive as ever. Its signature roofline and shapely greenhouse give the car a flowing, uninterrupted form that extends rearward to a new, more muscular fastback profile. New front-end styling this year links the CLS to other Mercedes-Benz sedans, an upgrade that suits it well. It is spearheaded with a larger, more ominous big-star grille, flanked by optional full-LED headlights. Body lines are sharply sculpted, and the Mercedes CLS moves further into coupe territory with its longer hood and shorter overhangs.

Notable Standard Equipment

The CLS400 will use conventional steel springs for its suspension, with all other CLS models employing an adjustable air suspension. 14-way power and heated front seats, leather upholstery, automatic climate control, multi-color ambient lighting, and an 8-inch audio display screen are also standard. Inside the CLS550, you’ll find a navigation system, 14-speaker harman/kardon sound system and many of the other amenities that are optional on the CLS400. In the name of safety, the Mercedes CLS provides 12 airbags, Attention Assist drowsiness monitor, Electronic Stability Program and bi-xenon headlights. A limited-slip rear differential is standard on the AMG S.

Notable Optional Equipment

Top options on the Mercedes CLS include full LED headlights, a rearview camera, heated and ventilated front seats, iPod interface, split-folding rear seats and an electric trunk closer. Available driver assist technologies include Adaptive Highbeam Assist, Distronic PLUS cruise control, Active Blind Spot Assist, Active Lane Keeping Assist, Parktronic with Advanced Parking Assist, and Night View Assist PLUS with Pedestrian Detection. The CLS63 AMG S 4Matic can be equipped with carbon ceramic brakes and Bang & Olufsen audio.

Under the Hood

New for 2015 is the CLS400. Powered by a 3.0-liter twin-turbo V6, the CLS400 pumps out an impressive 329 horsepower, which is more horsepower than offered by the entry-level Audi A7 or BMW Gran Touring. The 2015 Mercedes-Benz CLS550 is powered by a 4.7-liter twin-turbocharged V8 producing 402 horsepower and 443 lb-ft of torque. Power delivery is smooth and full-bodied, matched with quick, seamless shifts. It’s always a joy to have that much brute force at one’s disposal. Of course, it’s twice as much fun when you step into the CLS63 AMG S, which bumps output to 577 horsepower and 590 lb-ft of torque. Top speed for the 63 AMG S is limited to 186 mph.
